  □ Xue Qingxin

  "A glass of milk every day makes Chinese strong" is a classic milk slogan that many people are very familiar with. Drinking milk often is good for health. All along, China has been vigorously promoting the benefits of drinking milk. I hope everyone can drink milk every day.

  Not long ago, the 2022 edition of Dietary Guidelines for Residents in China was published. Compared with the 2016 edition of Dietary Guidelines for Residents in China, the new guidelines put special emphasis on milk intake. The original version recommended that the intake of milk and dairy products be 300g/day, but the recommended amount in the 2022 version has been increased to 300g-500g/day.

  This change further confirms the importance of drinking milk, and also reflects the importance China attaches to drinking milk.

  Even so, there will still be many different voices on drinking milk, and there are even people who strongly oppose drinking milk.

  But there are still many misunderstandings about milk.

  answer questions

  Drinking milk has hormones, and drinking it often can lead to precocious puberty? Not really!

  There are two sources of estrogen in milk: one is the natural estrogen contained in milk itself, which comes from the natural secretion of dairy cows during milk production; The other is artificially added estrogen, which is mainly used for infertility and cow disease treatment. Among them, the content of natural estrogen in milk is very low, which is not harmful to human body, and many common natural foods contain estrogen or estrogen-like, such as meat and bean products, and even breast milk contains estrogen, which is often higher than milk. The artificially added estrogen will of course be restricted by the state. China’s "Regulations on the Administration of Veterinary Drugs" clearly stipulates estrogen drugs, and related drugs may not be detected in animal foods. Therefore, as long as it is milk purchased by regular manufacturers, you don’t have to worry too much about estrogen.

  In addition, there is no evidence that drinking milk will lead to precocious puberty or damage children’s health. On the contrary, many studies show that the intake of milk and its products can increase the bone density of children, adolescents and postmenopausal women, which is beneficial to the growth and development of children.

  Adults drinking milk will not cause cancer. Studies have shown that milk and its products have nothing to do with the risks of breast cancer and prostate cancer. And drinking milk often may also reduce the risk of breast cancer by 16%, and drinking 200 grams of dairy products every day can reduce the risk of colon cancer by 7%.

  Therefore, on the whole, as long as it is milk produced by regular manufacturers, you don’t have to worry about cancer, so drink it with confidence.

  Milk and citrus fruits are the same? Rest assured to eat!

  There are rumors among the people that milk and citrus fruits are alike and cannot be eaten together, because milk will denature and precipitate after encountering citric acid in oranges, which will lead to stones.

  The truth is that when milk meets citrus fruits, precipitation may indeed occur. This is because the organic acid in the fruit breaks the acid-base balance. When the pH value just reaches the isoelectric point of protein, protein particles in milk are easily collided and condensed because of the weakened intermolecular force, and thus flocculent precipitation will occur. But these deposits are also edible, and many cheeses are produced in this way.

  Even if you don’t eat it with fruit, milk will precipitate and solidify after encountering stomach acid. Therefore, milk and citrus fruits can be safely eaten together, without poisoning or stones.

  Lactose intolerance: Do you want to quit milk? Actually, no!

  Lactose intolerance is very common in China. Lactase that decomposes lactose is lacking in the intestines of these people, and discomfort will occur after drinking milk, such as abdominal distension, abdominal pain and diarrhea. But even if there is lactose intolerance, it does not mean that it is necessary to quit milk.

  It is recommended to try the following four methods:

  ① Drink yogurt: During the fermentation of yogurt, lactose will be decomposed by microorganisms to produce lactic acid, which will reduce the lactose content and relieve the symptoms of lactose intolerance. Another study shows that increasing the intake of yogurt can improve the symptoms of lactose intolerance.

  ② Drink 0 lactose or low lactose milk: It is very suitable for lactose intolerant people to drink by using special technology to hydrolyze lactose in milk.

  ③ People who are only slightly lactose intolerant can try to improve lactose tolerance: drink 60-120g pure milk 2-3 times a day for 3 weeks after each meal, and gradually induce the intestine to enhance lactose tolerance.

  ④ Low-salt cheese: According to protein ratio, 10 grams of cheese is equivalent to 100 grams of milk.

  Is the milk with long shelf life because of preservatives? fault

  Many milk on the market has a shelf life of up to 6 months, so some people think that it is secretly added with preservatives.

  In fact, there is no need to add preservatives to milk, and the shelf life depends on the sterilization method of milk.

  The shelf life of pasteurized milk is generally short, usually 7 days, and it needs to be stored in cold storage; However, milk sterilized at ultra-high temperature instantly kills almost all microorganisms and bacteria during sterilization, so it can still be preserved for a long time without preservatives, generally up to 6 months, and can be stored at room temperature.

  Now there are many transparent packaging bags of milk on the market, the price is relatively high, which can directly see the true color of milk and give people a very fresh feeling. Many consumers also prefer to buy this kind of milk, thinking it is more nutritious and more comfortable to drink. In fact, transparent packaging bags do not mean that milk is fresher and more nutritious. Vitamin B2 in milk is a photosensitive substance, which is unstable under light. However, milk in transparent packaging bags is often directly exposed to sunlight and light, which may increase the loss of vitamin B2 in milk.

  However, opaque milk packaging can be stored away from light, which can better preserve the nutrition in milk.

  remove a doubt

  Continue to drink milk. Is a kilo a day enough?

  Most people in our country don’t drink enough recommended milk.

  According to the Scientific Research Report on Dietary Guidelines for Residents in China 2021, in 2015, the per capita milk intake in Chinese cities only reached 14% of the recommended amount in the 2016 edition of Dietary Guidelines, and it will be lower in rural areas. In other words, most people in China don’t drink enough milk. Milk is a good source of calcium supplement. If milk intake is insufficient for a long time, it may increase the risk of calcium deficiency.

  Milk can not only supplement calcium, but also provide high-quality protein and vitamin B2. Lactose in milk can also promote the absorption of minerals such as calcium, iron and zinc.

  The recommended milk intake in the 2022 edition of Dietary Guidelines for China Residents has increased to 300 -500 grams per day — — A kilo (500g) of milk a day is actually necessary. For special people with high calcium demand, it is still difficult to make up enough calcium even if they insist on drinking 300 grams of milk every day. For example, teenagers, women in the second and third trimester of pregnancy, nursing mothers and people over 50 can only supplement 321 mg of calcium if they drink 300 g of milk every day, which means they need to take 500 mg -900 mg of calcium from other foods.

  In addition to milk, green leafy vegetables and bean products are also sources of calcium supplementation, but influenced by phytic acid and oxalic acid, the absorption rate is mostly not as good as that of milk. For example, the calcium absorption rate of tofu is only 15%; The calcium content of celery is 191 mg /100 g higher than that of milk, but the oxalic acid content is as high as 231 mg /100 g, the available calcium is only 79 mg /100 g, the leek calcium content is 105 mg /100 g, the oxalic acid content is as high as 162 mg /100 g, and the available calcium is only 34 mg /100 g. (Editor’s Note: Phytic acid can produce insoluble compounds with metal ions such as calcium, iron, magnesium and zinc; Oxalic acid can reduce the bioavailability of mineral elements, and it is easy to form calcium oxalate with calcium ions in human body, leading to kidney calculi).

  I really don’t like drinking milk. How can I supplement my nutrition?

  There are some people who just don’t like the taste of milk or are allergic to dairy products, so they really can’t drink milk to supplement calcium. There are also some friends who are always suspicious of milk and are unwilling to drink it. So how can these people get enough calcium?

  For people who don’t like the taste of milk, milk and fruit can be made into milkshakes, such as strawberry milkshakes, banana milkshakes, mango milkshakes, etc., and the taste is mostly acceptable; You can also make custard and steamed bread with milk or milk powder; Yogurt and cheese are also good choices. According to protein ratio, 12.5 grams of milk powder is equivalent to 100 grams of milk.

  For people who are allergic to milk, they can’t eat any dairy products, and they often worry about insufficient calcium intake. It is suggested to choose vegetables with high calcium content, such as rape, Chinese cabbage, radish tassel, fennel and coriander, while vegetables with high oxalic acid, such as spinach, amaranth, water spinach and celery, can be blanched before eating. Eat 300 -500 grams of vegetables every day, and the cooked vegetables are about 100 grams in size.

  Bean products are recommended to eat at least 50 grams of soybeans, such as two fist-sized tofu or four pieces of dried tofu or 1.5 fist-sized shredded tofu.

  In addition, calcium can also be supplemented appropriately. It is recommended to choose a small dose, preferably 100 -300 mg of calcium per tablet, which can be supplemented flexibly.

  If you drink milk, you will get acne. What should I do?

  Many friends actually like to drink milk, but it is helpless that when they drink milk, their faces will explode. This situation may be due to food intolerance to milk. Casein in milk can promote the secretion of insulin and IGF-1, leading to acne.

  In particular, skim milk may be more serious than whole milk, so it is also mentioned in the China Acne Treatment Guide (2019 Revision) that if you have acne, you should pay special attention to limiting the intake of skim milk, and you can try sugar-free yogurt and low-salt cheese.

  Some people also like to use milk as a mask, thinking that drinking milk and smearing milk can whiten the skin. In fact, this statement is unfounded. Black people also drink milk, and their skin color is still black.

  The main ingredients of milk are water, protein, fat, calcium, etc. These ingredients have no special effect on whitening, even if you wash your face with milk every day, it will not whiten.

  Skin color is closely related to genetic factors and environmental factors, and it cannot be changed by eating any kind of food. Drinking milk is recommended, but don’t expect whitening; As for washing your face with milk, don’t waste it again.

  summary

  From the point of view of calcium supplementation and disease prevention, it is necessary to have 300 -500 grams of milk every day. If you especially like to drink milk and drink more than 500 grams a day, then it is more recommended to choose low-fat milk, or reduce the intake of other oils in moderation, and avoid the total energy exceeding the standard.

  Interview with Lou Wenyong, Professor of South China University of Technology;

  If you want to supplement calcium, besides drinking milk, you should also supplement CBP.

  Text/Yangcheng Evening News reporter Sun Lei

  South China University of Technology Press timely published a popular science book "Basic Protein CBP in Colostrum and Bone Health", which was co-edited by Professor Lou Wenyong of South China University of Technology, Dr. Zeng Yingjie of Southwest University for Nationalities and popular science author Li Daiwei.

  The book emphasizes that a colostrum basic protein (CBP) can directly act on bone cells, promote osteoblast proliferation, and greatly enhance the absorption and utilization of calcium. Combining with calcium, it can effectively increase human bone density and bone length of children and adolescents.

  CBP is made from bovine colostrum through sterilization, degreasing, centrifugal separation, ultrafiltration and other processes. Scientific research shows that CBP is an active protein with a molecular weight of only 30 kDa, which can directly act on bone cells, promote the proliferation of osteoblasts and greatly enhance the absorption and utilization of calcium. Therefore, CBP can inject new energy into bone health, and this mechanism is also called "CBP bone energy".

  It is reported that in August 2021, the College of Food Science and Engineering of South China University of Technology and Peizhi Health Center organized a "90-day CBP Bone Energy Experience Program", in which 31 subjects including faculty and staff of South China University of Technology participated in the test. The test and statistical results show that about 90% of the subjects’ bone mass has been improved or maintained in good condition, and the remarkable effect accounts for about 65%.

  Speaking of the legend that "milk contains hormones, which are harmful to health for adults and precocious puberty for children", Lou Wenyong also said that this statement exaggerated the influence of hormones in milk on people. "Growth hormone is a kind of protein secreted by animals’ brains. Almost all animal milk contains a small amount of hormones to promote the growth of animals. Undoubtedly, as long as it is milk squeezed by healthy cows, its hormones are very low and meet safety standards, so don’t worry too much. " He said that milk is rich in nutrients such as calcium, vitamins, protein and trace amounts of bone growth factors CBP, lactoferrin, immunoglobulin, etc. It is self-evident that drinking milk for a long time is beneficial to health. "Humans have been drinking milk for thousands of years. Facts have proved that children who drink milk for a long time are generally taller than children who don’t drink milk. Adults who insist on drinking milk are also healthier. That’s why ‘ A glass of milk a day makes a nation strong ’ The statement. "

  But he also stressed that it is impossible to effectively supplement CBP by drinking milk alone. He said that the content of CBP in ordinary milk is only 0.15% (0.015‰ ), the content in bovine colostrum is only four ten thousandths (0.4‰ ), the content is extremely low, very rare. Therefore, it is necessary to extract CBP from milk and bovine colostrum and add it to related products to realize an efficient and rapid CBP supplement method. At present, CBP can be added to nutritious food alone, and it can also be combined with other nutrients to play a better role. For example, the DKC gold combined bone energy composed of CBP, vitamin D and vitamin K2, or immunoglobulin IgG, intelligent nutrition phosphatidylserine PS, etc.

  In addition, Lou Wenyong also suggested that developing good living habits, such as eating more foods with high calcium content, ensuring adequate sleep, getting more sunshine, and appropriately increasing exercise load, will make the effect of CBP on improving bone health more obvious.

Kong You and Jeon Do-yeon will join "Men and Women" to present a large-scale sex scene.


Jeon Do-yeon, Kong You.

    1905 movie network news Korean actors Kong You and Jeon Do-yeon will join hands in the new film directed by Yoon-ki Lee. In February this year, it was reported that Jin Yunshi and Jeon Do-yeon were expected to join the film, and it is now confirmed that Kong You will take over Jin Yunshi’s role.
 
    "Men and Women" is a large-scale love movie about a pair of men and women who fall in love after meeting in Finland. Kong You will dedicate her first nudity and sex scene after her debut. And Jeon Do-yeon, a predecessor of Kong You’s company, took the film out of his trust in Jeon Do-yeon.
 
    Jeon Do-yeon will also be bold and naked in this film. As early as 1999, Jeon Do-yeon appeared in a large-scale sex scene in the film and became a hot topic. Later, she stepped onto the red carpet of Cannes International Film Festival with her large-scale performance full of functional stimulation. This time, in the new film "Men and Women", the audience will see Jeon Do-yeon’s unique large-scale acting skills. The film also said: "Men and Women will portray the emotional lines of the hero and heroine in a delicate and charming way. Although there is some burden on nudity, both actors have shown positive intentions. "
 
    Yoon-ki Lee, the director of "Men and Women", has directed films such as,, etc. Jeon Do-yeon once starred in Wonderful Day with director Yoon-ki Lee and actor Ha Jung Woo, and this time he also strongly supported Yoon-ki Lee’s new work. Jeon Do-yeon was still filming, and after receiving the proposal of "Men and Women", she readily agreed without hesitation.
 
    Last year, Kong You’s starring role mobilized 4.13 million audiences, and after that, it was a box office success again. Originally, it was confirmed that I would star in a new film adapted from online comics with an investment of more than 15 billion won. However, due to the delay in starting the movie, I was very willing to cooperate with my predecessor Jeon Do-yeon after receiving the proposal of "Men and Women". The new film is expected to be filmed in Jeon Do-yeon after a short break.
 
    The production company "Spring" has previously produced "Wonderful Day" starring Jeon Do-yeon and several films directed by Hong Shangxiu, which were released by CJ E&M..

Can pets make money? Watch out! It could be a pit.

  Now with more and more people keeping pets, related industries have also formed a scale. Some of them want to make money by raising pets and selling cubs. Is this money really that easy to earn? Recently, the reporter received a related complaint to remind everyone.

  I spent tens of thousands of yuan for half a year and didn’t earn a penny.    

  When Mr. Zhou, who lives in Fenghua, was at home, he found an organization called "Ningbo Langchong International Maine Cat Breeding Base" on the Internet, claiming that he could make a profit by raising pet cats and selling cubs. So, Mr. Zhou contacted the agency and planned to make some money by raising pet cats.

  "I live in Fenghua. This institution is in Jiangshan Town, Yinzhou, and it is quite far every time." Mr. Zhou told reporters that in January this year, he reached an agreement with the organization, and the other party gave him a male cat and five female cats for breeding kittens. When the kittens were born, the company was responsible for repurchase.

  Mr. Zhou said that he keeps Maine cats, which are relatively large. For this reason, he also bought a cat cage, rented a house and installed air conditioning, thinking that he could make money by selling cats.

  "We didn’t have any written agreement at that time. We all talked about it verbally. Later, they added a feeding entrustment agreement to me." Mr. Zhou said, "I don’t have any culture either. I was very anxious at that time. They kept urging me, so I signed it. It was not until Alipay deducted the money that I discovered that the original account was automatically bound, and I had to deduct a lot of money every time. " He told reporters that at that time, the other party asked him to scan a QR code and enter a small program. The cat food, cat litter and other supplies needed for feeding should be purchased from here. The staple food purchase fee is paid once every three months.

  Mr. Zhou said that he was also full of confidence at that time. "I have raised cats before, and I know that cats can give birth in almost half a year, and there is more than one child per child. If they can buy back smoothly, they should be able to make money." However, what makes him feel uneasy is that although the staff later pulled him into a breeding group, there was almost no professional guidance. "Moreover, they didn’t deliver the cat in time according to the agreement. Every time the cat was sent, it was sick. They said that it was vaccinated, but every time I had to spend money to treat the disease, or simply change the cat." Mr. Zhou said that the agreement stated that the feeding fee should be paid half by half, but he has invested tens of thousands of yuan at present, but the other party has almost no cost except providing a breeding cat. "After a period of feeding, the female cat did give birth and finally survived three, but the promise of the agency to buy back at 4,000 yuan each was not fulfilled." As a result, Mr. Zhou went back and forth between Fenghua and Yinzhou several times, hoping that the other party could keep his promise, but the other party evaded it for various reasons and has been delaying it. So, he complained to the 12315 hotline, hoping that the company could buy back the cat and compensate him for the related losses.

  The reporter visited the scene and there were dozens of cats.

  According to the address provided by Mr. Zhou, the reporter went to this institution named "Ningbo Langchong International Maine Cat Breeding Base" located in Jiangshan Town, Yinzhou District. The reporter found the company in a factory area, and only after asking the security guards did he know that the company rented their office. On the 4th and 5th floors, the reporter saw that the air-conditioned rooms here were filled with dozens of cats of all kinds, large and small, and there were also many cats in other warehouses and aisles. In one of the offices, there are many disposable injections and many medicines. It seems that cats are injected with related vaccines and antibacterial drugs.

  The reporter asked the relevant staff as an ordinary breeder. The staff member said that they have two ways here, one is adoption. Consumers can get cats free of charge, but they have to buy cat food and related products on their designated websites, each for one month, with a total of 12 issues.

  According to the variety of cats, the cost is different, usually several hundred yuan per month. The other is entrusted breeding. The company provides a male cat and a number of female cats for breeding. According to the variety and quantity, different fees are charged.

  In addition, you need to buy cat food and related products in the designated online mall for a period of 2 years.

  "That at that time, the kitten born you responsible for repurchase? How about the price? " The reporter continued to ask. "This depends on the market situation. We will have an approximate price, depending on the situation at that time." The staff member said that he had just come to work, and many details were unclear.

  The reporter also asked about vaccination. The staff member said, "We can give you a vaccination, or we can give you vaccines and tools. Just go back and do it yourself." He said that this is very simple and does not require any qualifications, as long as it is injected subcutaneously. "It’s usually around the neck."

  Subsequently, the staff member showed the reporter an electronic version of the agreement, saying that the printer was broken and the paper version could not be printed. The reporter looked at it, and the content of the agreement was similar to that provided by Mr. Zhou.

  Subsequently, the reporter also asked for the phone number of Mr. Hu, the relevant person in charge of the company, but he called several times and no one answered. Mr. Hu was not contacted as of press time.

  Lawyer’s statement: If the business fails to honor its promise, it may be suspected of fraud.    

  However, the reporter also found that there are many complaints about free adoption of pets on the Internet. Some businesses sell all kinds of pet products under the banner of free adoption, and many consumers are "trapped".

  There are still many people on the internet who post the information of "free pets". However, some of them take advantage of the adopters’ love to make friends with each other, such as bundling high-priced and inferior pet toys, snacks and supplies or signing a fixed purchase agreement, so that the adopters can pay more than the pet’s own value and gain benefits. In the end, the free adoption of pets became a "strong sale". The adopters questioned whether the pet adoption agreement was fair and reasonable and were unwilling to continue to perform the agreement, which caused disputes between the two sides. According to media reports, some people use false pet information for profit, which is huge and even suspected of fraud.

  To this end, Han Zhiqing, a partner of Zhejiang Tongzhou Law Firm, said that if the merchant has never redeemed the cat pups from the pet adopters and shared the expenses according to the contract, it is likely to have been suspected of fraud; However, if there are not many deceived people reporting the case, the public security organs will probably think that it is only a civil dispute. At the same time, the adopter should make a risk assessment in advance for the bundled deduction of purchase expenses and the other party’s failure to fulfill the repurchase obligation and share the agreed expenses; Clear the time for the other party to fulfill its obligations, such as timely sharing of monthly purchasing expenses, such as overdue sharing of expenses, failure to fulfill the obligation of cat cub repurchase and other breach of contract, with clear constraints and responsibilities.

From the whole vehicle to the parts, 100,000 kilometers of vehicles are completely dismantled.

  [car home Technology] After driving for a certain mileage, vehicles often have slightly different driving feelings from new cars, and the reason for this is ultimately attributed to the components that make up the vehicle. Therefore, we have done such a thing, completely disassembling a family car that has traveled 100,000 kilometers in a short time, which is the first time for us.

Home of the car

  Because it is the first time to make such a topic, we found many problems in the planning process, which may lead to the failure of the dismantling project, such as the dismantling site, vehicles used for dismantling and related technical support. Therefore, we finally decided to cooperate with automobile manufacturers. After a long period of communication, Dongfeng Nissan Qichen accepted our proposal.

Why choose a car that travels 100,000 kilometers for disassembly?

  The reason why the mileage of 100,000 kilometers is selected is because when a car travels more than 100,000 kilometers, some faults and problems will gradually emerge, which has little to do with the brand and price of the vehicle, that is to say, even millions of high-end brand vehicles may have various problems.

  By disassembling a vehicle traveling 100,000 kilometers (disassembling it to the most basic component level, such as a bolt or a bearing), we can tell you which components will wear, especially the chassis system and powertrain system, which are normal and which are abnormal, and how these wear will be related to the final vehicle performance. In this process, we will also tell you how to reduce this unnecessary wear in daily use.

● Which car to dismantle?

  Initially, we had several basic requirements for vehicle selection:

  1. The longer the mileage is on the basis of 100,000 kilometers, the better;
  2. The vehicle has not been modified in power and performance, and it is all set by the original factory;
  3. The vehicle has not had any accidents;
  4. The vehicle is the original paint;
  5. The vehicle is normally maintained in the 4S shop according to the regulations.

  The vehicle has not been modified and has not had an accident. At the same time, these conditions are maintained normally, and some interference factors are eliminated as much as possible. Only in this way can the contents presented by disassembly be more representative. Based on the above points, (click for details) we have collected vehicles in the forum. In addition, you may also see the collection information of vehicles in the 4S shop. After screening, a Qichen D50 was finally locked.

Qichen Dongfeng Nissan Qichen D502012 1.6L Manual Comfort Edition

Ran 100 thousand kilometers a year!

  The Qichen D50 we chose has a mileage of more than 100,000 kilometers in more than one year, and the average daily mileage is more than 300 kilometers. We only know the reason by asking the owner. Because of business needs, car owners often drive back and forth between cities in the Pearl River Delta region. Most of the roads they drive are high-speed and relatively smooth national roads, while the rest are relatively congested and complicated urban roads.

Where shall we open it?

Qichen Dongfeng Nissan Qichen D502012 1.6L Manual Comfort Edition

  Such disassembly requires the cooperation of the site and relevant personnel. At the same time, we also hope to send the vehicle to a professional institution for testing and verify the state of the vehicle through the test data. Based on the above demand, we transported the vehicle to Dongfeng Nissan Factory in Xiangyang City, Hubei Province for disassembly. It is worth mentioning that it can also be borrowed from the professional test site in the factory to evaluate the vehicle subjectively.

 Basic information of the vehicle

Qichen Dongfeng Nissan Qichen D502012 1.6L Manual Comfort Edition

  This Qichen D50 was produced in April 2012, and the specific model is the 2012 1.6L manual comfort version. The owner bought this car in June last year. After buying a car, the owner first installed an electric rearview mirror in the 4S shop (it is indeed a very practical configuration, and the manufacturer seems to realize this, which became the standard of the whole department on the 2013 Qichen D50), an anti-theft device, a leather seat and a reversing radar. We found a slight crack at the adjusting button of the electric rearview mirror, which may be caused by the later installation.

Qichen Dongfeng Nissan Qichen D502012 1.6L Manual Comfort Edition

  For more than a year, the owner carried out routine maintenance in the 4S shop according to the provisions of the maintenance manual. At the same time, during the use process, the owner himself felt that there was abnormal noise at the position of the generator and the front shock absorber. After going to the 4S shop for inspection and maintenance, he finally replaced the generator and the right front shock absorber free of charge through the claim procedure. In addition, before lifting the new car, the engine harness was damaged due to the storage problem of the car, so the engine harness was also replaced.

Owner’s evaluation of the car 

  In more than a year’s use, the owner is satisfied with the overall performance of the car, and there has never been any breakdown on the way to and from the city. Because it is located in the high humidity and high heat environment in the south, the owner turns on the air conditioner every time he gets on the bus. According to the road conditions explained earlier, the fuel consumption is more than 6 liters per 100 kilometers, and the owner is quite satisfied with this fuel consumption. The owner also thinks that the noise of the engine of the car is relatively small and the gear is very clear. In addition, the owner is also very satisfied with the space performance of the car and the cooling effect of the air conditioner. As for the shortage, the owner thinks that the interior of Qichen D50 is too simple, and I think this is also a compromise that has to be made from the perspective of cost control.

Editor’s subjective driving experience (static+dynamic evaluation)

  The vehicle has been explained clearly, and after listening to the owner’s feelings about the car, let’s make a subjective evaluation. Let’s see what changes will happen to the vehicle driving 100,000 kilometers from the most intuitive feeling. To this end,We found a 2013 1.6L manual deluxe version of Qichen D50 (hereinafter referred to as the new car) with a mileage of only over 2,000 kilometers for comparison, thusFeel the difference and difference more obviously.

-Good appearance and interior color.

Qichen Dongfeng Nissan Qichen D502012 1.6L Manual Comfort Edition

   Perhaps it is because of the relatively short service life and the care of the owner. In short, it is difficult for us to associate this car with driving 100,000 kilometers through static observation. Its appearance and interior color are good, and all functions of the vehicle are normal.

-Abnormal sound may come from generator pulley bearing.

  After landing, under the condition of quiet external environment, there was abnormal noise coming from the pulley side of the engine crankshaft, and it was preliminarily judged that it came from the pulley bearing of the generator. If this is the case, it can be seen that the generator assembly replaced by claim has the same problem again. But whether the abnormal sound comes from here or not, we have to wait until the disassembly to find the real answer.

 -There is slight abnormal sound at the stop bar.

  We found that this old car will have a slight abnormal noise when it is in gear, but it will not affect the clarity of gear and the feel of shifting. We feel that this abnormal noise is probably caused by the lack of adequate lubrication of the gear selection mechanism. In the later disassembly, we will further confirm the cause of the problem.

Qichen Dongfeng Nissan Qichen D502012 1.6L Manual Comfort Edition

-The noise of the old car is slightly louder than that of the new one.

  In terms of noise, we selected two points: idle speed and 80km/h (the engine speed is about 2000rpm after the manual gear D50 is engaged in the fifth gear at this speed) to compare and test the new car and the old car. From the results, the new car is better than the old car with a mileage of 100 thousand kilometers, but the advantage is relatively small, especially when idling, the abnormal noise from the pulley of the old car leads to the obvious noise of the old car in idling. In fact, the increase of noise is an unavoidable problem for any vehicle, because the rubber and related materials that play a role in sealing and sound insulation will age to a certain extent with the passage of time, which will lead to the noise can enter, thus making the noise of vehicles rise slightly.

-The dynamic performance of the old car is better than that of the new car before the running-in period.

  In addition, we entrust a third-party testing organization to test the dynamic performance of two Qichen (one new and one old) (the tires are all new tires of the same brand and series). Judging from the final results, the dynamic performance of the old car that has traveled for 100,000 kilometers is better than that of the new car, and it is not unusual to see this situation. After all, the new car is still in the running-in period, and the power and chassis system have not yet reached the best running-in state. In addition, although the old car has been fully run-in, there will be a certain degree of attenuation in the power system, but the attenuation of this car is not obvious because of its good driving condition, which can also be confirmed by the disassembly of the engine and transmission of the old car in our later period.

Comparative experiment of dynamic performance (not representative of all operating conditions, for reference only) Experimental project New car Old car Maximum speed (km/h) 186.9 189.2 0-100km/h acceleration time (s) 11.59 11.44

-the new car is tighter and the old car is slightly loose.

  In terms of actual driving experience, we choose to carry out it in a closed test site, where there are many different roads that can simulate the bumps, twists, speed bumps, asphalt roads, stone roads and gravel roads that vehicles may encounter when driving on actual roads.

Qichen Dongfeng Nissan Qichen D502012 1.6L Manual Comfort Edition

  By comparing the test drive of two vehicles, the first obvious feeling is that the new car is more compact and complete, while the old car is slightly loose. When passing through cobblestone sections, the interior parts of the two cars will have obvious abnormal noise, while the old car is more prominent. I think this may be related to the deformation of the plastic parts in the car after a certain period of use and the change of assembly clearance.

Qichen Dongfeng Nissan Qichen D502012 1.6L Manual Comfort Edition

  When I was driving at a speed of about 20km/h on a twisted road with ups and downs, I could obviously feel that the potential energy of the spring could not be reduced and absorbed quickly because of the performance attenuation of the shock absorber in the old car, which made the body bounce relatively greatly, while the body bounce of the new car was smaller. Based on this, we have to dismantle the shock absorber destructively in the later stage to see what happened inside the shock absorber, and please pay attention to our subsequent disassembly report.

Summary:

  Through subjective driving experience, we have a preliminary understanding of the basic situation of the vehicle. In terms of appearance, interior and various functions of the vehicle, the vehicle has maintained a relatively new level. However, after all, I have already traveled 100,000 kilometers, and I immediately felt the obvious difference through driving. We have also recorded some good or bad situations found, and we will find the corresponding answers for everyone in the later disassembly. (Text/car home Feng Jingyi)

Next notice:

  At the beginning of this topic, this paper mainly explains the daily use of this vehicle which has traveled for 100,000 kilometers. In addition, we will also analyze the subjective evaluation of static and dynamic driving, and find the answer to the question through detailed disassembly in the later period.

Home of the car

  [car home Technology] With the increase of mileage, the aging characteristics of vehicles are becoming more and more obvious. For drivers, abnormal noise is the most intuitive category. As mentioned in our previous article, the owner judges that there may be some problems in the vehicle based on abnormal noise, and the subsequent inspection results also confirm the reliability of this intuition, and those silent changes are also taking place. We ended them when the odometer of Qichen D50 entered the 100,000-kilometer mark. This article will show you the situation of the body and chassis.

  Don’t underestimate the structure of this energy-absorbing box. Through literal understanding, we know that its function is to absorb collision energy by virtue of its own deformation in the event of collision, so as to reduce the impact on the back.

  It’s easy to say, but it needs careful design to achieve better energy absorption effect. On the one hand, the wrinkle design on its surface divides the energy absorption process of the energy absorption box into three parts, which makes the energy absorption process of each part relatively independent and stable, and the position and amplitude of these two folds are obviously calculated through a lot of calculations. In addition, the energy-absorbing box connected by bolts can effectively control the maintenance cost.

  In the energy-absorbing box, different cars have different structures, some cars are not equipped with energy-absorbing boxes, some cars are equipped with energy-absorbing boxes but have no wrinkle design. In addition, there is a difference in the connection mode of energy-absorbing boxes. Some cars’ energy-absorbing boxes are connected with anti-collision beams and longitudinal beams by welding.

Further disassembly in the car

  The next step is to disassemble the car body further. In the end, what we see is just a car body, just like the car body we see in the painting workshop every time we visit the factory. Although it is impossible for us to judge the anti-corrosion ability of the car body by using it for more than one year, when it is "naked" in front of us, we can clearly see the structure of the car body and the workmanship inside and outside. This is also a very noteworthy link.

Passenger compartment structure

  As we all know, the coating process carried out in the vehicle manufacturing process can ensure the corrosion resistance of the car body. As long as the paint surface of the car body is not damaged in the later use of the car, in general, the car body steel plate can be guaranteed not to be rusted in 10 years. Of course, the process of the steel plate itself is also very important. We learned from the manufacturer that the Qichen D50 uses galvanized steel plate with good corrosion resistance, which also ensures the aging resistance of the car body to a certain extent.

  As we expected, there are no signs of years such as rust or dim color on the surface of the car body. For such a car with a driving time of about one year, it is really difficult to judge its anti-corrosion performance, but in any case, we can still gain something in the process of disassembling the car body, such as the materials and structure of the car body.

The third stage: chassis disassembly

  According to our previous experience of comparing the test drive of new and old models, Qichen, which has traveled for 10,000 kilometers, did show some fatigue in the chassis link. For example, after passing through the ditch and ridge road for many times in a row, the vibration absorber’s ability to restrain the body shaking has declined, and we hope to find the answer in the subsequent disassembly.

Suspension disassembly

Qichen Dongfeng Nissan Qichen D502012 1.6L Manual Comfort Edition

Front suspension disassembly

  The front suspension structure of Qichen D50 is McPherson-style, and the process of detaching it from the car body together with the subframe is not complicated. The subframe and the car body are connected by four bolts, but before loosening them, we need to disconnect the connection between the damping strut and the car body and the engine support elements, and then the suspension assembly and the engine are detached together. Next, we will analyze the suspension disassembly, and the engine disassembly will be arranged at the end.

steering rod ball

  Under normal circumstances, the car that has traveled for 100,000 kilometers is prone to problems, which is the abnormal sound or looseness caused by the aging of the rubber parts of the chassis. The ball head of the steering rod is a part that is prone to problems. The ball head of the steering rod is responsible for connecting the steering rod and the steering knuckle. Besides the ball head, there is lubricating oil in it. Once the rubber sleeve outside is damaged due to aging, on the one hand, the lubricating oil will leak out; on the other hand, dust, dirt and rain may also enter the ball head, which will accelerate the wear of the ball head, and then the damping force on the swing of the ball head will become smaller, and its interior will begin to wear and gradually become loose.

Qichen Dongfeng Nissan Qichen D502012 1.6L Manual Comfort Edition

  For the driver, it may be felt that the virtual position of the steering wheel is getting bigger (loose and spacious, which can be felt by shaking the wheels with both hands after lifting the car). On the other hand, it will also affect the stability of the vehicle when it is dynamic to some extent. From the disassembly of Qichen D50, we can see that the steering rod ball head is in good condition, and the steering wheel is not found to be too empty during the previous test drive, so it can be judged that there is no problem in this part. However, the aging of rubber covers is also related to time, which generally does not happen when the car is used for more than one year.

Rear suspension disassembly

  The rear suspension of Qichen D50 adopts the longitudinal arm torsion beam structure, and the simple structure is the advantage of this kind of suspension structure, especially for compact cars like Qichen D50, it is particularly important to contribute more space to the interior of the car.

Disassemble shock absorber

  The situation that the body sway can not be suppressed as soon as possible is mostly directly related to the shock absorber. With the increase of mileage, its performance will gradually decline. In addition, continuous and high-intensity work will also reduce its performance.

Qichen Dongfeng Nissan Qichen D502012 1.6L Manual Comfort Edition

  Before disassembling, we made a static comparison of the height of the car body. In the case of no load, there was no obvious difference between the heights of the old and new cars, which to some extent showed that there was no big problem with the springs supporting the height of the car body. Next, we will further disassemble the shock absorber strut and shock absorber.

  This kind of shock absorber with double-tube structure is widely used in ordinary household cars. After many times of intensive work, the hydraulic oil and air inside may be mixed together, which will lead to a large number of bubbles in the hydraulic oil. In this state, the performance of the hydraulic oil is bound to be greatly affected. This may be the reason why the car body shaking in Qichen D50 cannot be suppressed as soon as possible. The above is only our theoretical analysis according to the structure.

Abnormal wear of tires

Wear difference between front and rear tires

  When cleaning up the workshop, we accidentally found that the removed tires showed signs of abnormal wear. Usually, this is related to the four-wheel alignment of the vehicle and daily use.

Qichen Dongfeng Nissan Qichen D502012 1.6L Manual Comfort Edition

  According to our understanding, the tires of this Qichen D50 have not been changed during the driving period of 100,000 kilometers. Only during the maintenance period, the maintenance technician found that the wear of the front and rear tires was obviously different, and the front and rear tires were switched. However, we can still see some clues from the wear of the tire surface.

Qichen Dongfeng Nissan Qichen D502012 1.6L Manual Comfort Edition

  For most (engine-front) vehicles, because the center of gravity of the vehicle is relatively forward, the pressure on the front tire is greater. According to the physical definition, the friction between the tire and the ground is greater when the contact area is fixed. In contrast, the wear of the front tire is more serious than that of the rear tire.

  From this point of view, it is very necessary for us to switch the front and rear tires regularly during our daily car use, which can make the wear state of the front and rear tires more uniform, thus delaying the service life of the tires. Specifically, the front-back exchange or diagonal exchange can be adopted, but if the tire has a rolling direction mark, then the same side can only be used for the front-back exchange when the tire is transposed. This requires special attention.

Eccentric wear of tires

  In addition to the difference between the front and rear tires, the tires used as front wheels for a long time have eccentric wear. From the tire surface, the degree of wear on the outer side is more serious.

Qichen Dongfeng Nissan Qichen D502012 1.6L Manual Comfort Edition

  This may be a problem with the four-wheel alignment of the vehicle, but it may also be caused by the tire being in a state of insufficient air pressure for a long time. Modern cars tend to set camber to a negative value to improve the driving stability of the vehicle. If the tire is in a state of insufficient air pressure, it will aggravate the wear on the outside of the tire when the vehicle turns.

Editor’s summary:

  The Qichen D50, with a mileage of over 100,000 kilometers, shows no obvious signs of aging in the body and chassis. Among them, because the service life of the vehicle is about 1 year, and under normal circumstances, the painting process can ensure that the car body will not be rusted for 10 years, so it is difficult to fully show the anti-corrosion state of the car body. In addition, in the chassis link, we focused on the problem of vehicle body sloshing after passing through the ditch and ridge. Through structural analysis, after many bumps, the mixing of oil and gas in the shock absorber may be the chief culprit leading to damping attenuation. No signs of aging were found in the rubber bushings between the various connectors of the chassis. On the one hand, the quality of the components themselves was excellent, on the other hand, it was related to driving habits and car use time. In the next article, we will disassemble the powertrain. Compared with the body and chassis, the driving of 100,000 kilometers is a greater test for this part. (Photo/Text car home Li Boxu)

The fourth stage: engine disassembly

● Find the source of abnormal noise on one side of the engine pulley.

  First of all, we have to remove the generator, air conditioning compressor and other accessories from the engine. We turned the pulley of the removed generator by hand, but we didn’t find the abnormal sound we heard in the subjective evaluation before. It can be seen that the abnormal sound didn’t come from this, and finally it was determined that the root cause was the tensioner.

  Generally, the design concept of Japanese manufacturers is to achieve the initial requirements through the simplest structure as possible, so the design similar to Qichen, which is adjusted by screws, can automatically adjust the tightness of the belt according to the tightness of the belt, although it is not like the automatic tightening wheel designed by German manufacturers, but its advantage lies in its durability.

  Although the belt connecting the engine accessories is not like the timing belt (most vehicles use timing chain nowadays), once it breaks, the intake and exhaust valves of the engine will be seriously damaged, but it also needs to be checked daily. If it strikes, the generator will not work and the vehicle will break down.

  Both crank-connecting rod mechanism and valve timing structure run well after 100 thousand kilometers. Although you can clearly see the friction marks, they are all normal phenomena. This is not only due to the manufacturing accuracy, but also due to the engine oil, and changing the engine oil regularly is the best protection for these metal parts that are always in a harsh environment.

  Although we often mention the word "carbon deposit", it will still be incredible when we see these things strongly attached to the relevant parts of the engine. Indeed, no matter how good the oil, car habits, car environment and other conditions are, carbon deposition is always inevitable, but some cars are more serious and some cars are less serious. For example, it is easier to form carbon deposition when driving on congested roads in cities, and once it is formed, it is difficult to completely remove it.

  After 100 thousand kilometers, the powertrain system is still in good condition, especially the degree of wear is low, so the importance of regular maintenance is self-evident. However, the generation of carbon deposit is inevitable. When it is serious, it will have a great impact on fuel consumption and power. If you want to completely remove it, you must completely disassemble the engine to solve it.

  At this point, our topic of "100,000-kilometer vehicle dismantling" is over. Through dismantling, we show you what changes will happen to a vehicle that travels 100,000 kilometers, so as to help you develop good driving habits and strengthen the daily inspection and maintenance of the vehicle.

Ford Sharp L space has great power and low fuel consumption, but it is tepid because of these small flaws!

/private/var/folders/fn/lv20722j00db2njrm5bkhhd40000gn/T/com.kingsoft.wpsoffice.mac/picturecompress_20240409095801/output_1.jpgoutput_1

Ford L was released at Shanghai Auto Show in April, 2023. Its body length, width, height and wheelbase are 5000 mm, 1961 mm, 1773 mm and 2950mm, respectively, which makes it have obvious space advantages in medium-sized SUVs. The price range from low-priced fuel version to high-priced hybrid is 229,800 to 309,800 yuan, which can be said to cover the price range of mainstream compact, medium-sized and medium-sized SUVs, regardless of product strength.

/private/var/folders/fn/lv20722j00db2njrm5bkhhd40000gn/T/com.kingsoft.wpsoffice.mac/picturecompress_20240409102238/output_1.jpgoutput_1

However, from listing to the end of 2023, the total sales volume was 25,502 vehicles, with an average monthly sales volume of 2,125 vehicles, ranking 197th among the national passenger car sales. After combining the strength of its products, it is really a pity that such a flat sales performance has been achieved. You know, the average monthly sales volume of the same power split hybrid technology reached 6120 units.

/private/var/folders/fn/lv20722j00db2njrm5bkhhd40000gn/T/com.kingsoft.wpsoffice.mac/picturecompress_20240409102245/output_1.jpgoutput_1

Of course, the performance of sales volume is related to many factors, first of all, the product strength. Ford Sharp L adopts the latest design language of Ford family, and the spoke lattice air intake grille with dynamic LED headlights gives this SUV a strong visual impact, which is extremely aggressive compared with the old one.

/private/var/folders/fn/lv20722j00db2njrm5bkhhd40000gn/T/com.kingsoft.wpsoffice.mac/picturecompress_20240409102304/output_1.jpgoutput_1

The side of the car body is slender, and the uplift design of the C-pillar position adds a sense of movement. In terms of interior design, it is equipped with a 12.3-inch full LCD instrument panel and a 27-inch touch screen, which is reasonable in layout and convenient to operate. It not only provides rich information for passengers, but also enhances the sense of interactive experience. In terms of spatial layout, Ford Sharp L has realized the design of 2+2+3 with a wheelbase of 2950mm, and the maximum legroom in the second row is 1,190 mm. It is equipped with seat ventilation, heating, independent temperature zone control, wireless charging, etc. It can switch the near-zero gravity mode with one button, the backrest angle can be adjusted backward to 41 degrees, and the included angle between the backrest and the seat cushion can reach 105 degrees, making it comfortable to ride. The narrowest distance of the central passage is 200mm, and the armrest can easily enter and exit the third row after being folded, so that family users can experience comfort and convenience whether they travel daily or long distances.

However, the design is a matter of opinion, mainly in the actual experience, most users feedback that the hidden door handle can not be extended after unlocking, and it can be replaced or repaired through warranty. The display effect of the central control screen is average, and there will be problems such as crash, slow response, occasional blue screen, and unable to change the driving mode during use, which can be solved by restarting and upgrading the car. In the process of driving, the driver’s and passenger’s doors will produce abnormal noise when traveling in bumpy road conditions. The main reason is that the lock collides with the door lock, which can be solved by wrapping tape. There are also small problems such as abnormal sound of skylight and stuck ignition switch, which are within the scope of recall. In addition, the Ford Sharp L platform has been downgraded from the previous generation CD4 to the same C2 platform as Ford. Ford and Lincoln also use this platform. The material of the chassis suspension swing arm has been replaced by the seemingly cheap iron, which invisibly reduces the brand power and affects the choice of Ford potential users to a greater or lesser extent.

DSC_9470

To sum up, even if Ford Sharp L’s product strength is excellent, there is still much room for improvement in terms of quality reliability and brand strength. At the same time, in the impression that American cars bring to consumers, oil consumption seems to be an indelible stain. The Ford Sharp L 2.0T EcoBoost E- hybrid will make you change your view of American cars.

Ford Sharp L 2.0T EcoBoost E- hybrid is equipped with a hybrid system with power split configuration. When it comes to this technology, most people will take the lead in thinking of Toyota’s THS hybrid system. Yes, the hybrid configuration of Ford and Toyota is completely the same. However, Ford did not copy or buy Toyota’s hybrid technology. Strictly speaking, it is more appropriate to call it technology sharing.

Power split configuration was not first put forward by Toyota or Ford, but a design concept put forward by TRW Company in 1960s. When the development of new energy technology was officially valued by the main engine factory, Toyota and Ford began to develop this hybrid configuration at almost the same time. Among them, Toyota has made breakthroughs in control system and energy management, while Ford has put more energy into hybrid configuration and machinery manufacturing. In 2004, Ford signed an authorization agreement with Toyota. The details are that Ford replaced 20 patents related to hybrid technology with diesel engine technology. This behavior was misunderstood by many people. It was considered that Ford’s hybrid technology originated from Toyota, which is actually a kind of patent cross-authorization, because in the configuration of power split hybrid system, neither Toyota nor Ford can avoid each other’s patents. After evading the legal issues, Ford began to make great efforts in the power split hybrid configuration, including control strategies and algorithms, and applied for more than 100 patents.

So today, 20 years later, we saw this latest hybrid system on Ford Sharp L. The 2.0T EcoBoost E- hybrid consists of the fifth generation 2.0T EcoBoost single-turbo twin-turbo supercharged dual-injection engine and the eCVT transmission with dual motors. The maximum power is 202kW/5500rpm and the maximum torque is 405Nm/3000~4000rpm. Compared with Toyota 2.5THS, the power performance is better, and compared with Toyota 2.4T hybrid system, the cost control is better.

In the hybrid system, the engine uses a 350-bar dual-injection fuel system, which can automatically select the intake manifold or in-cylinder direct injection fuel injection mode according to the working conditions, which can better balance the low fuel consumption at uniform speed and the power performance at high power demand. At the same time, it also adopts hydraulic control OCV, VCT, valve mechanism and EGR exhaust gas circulation system. The eCVT transmission, code-named HF55, adopts a set of Power-Split structure in which the engine and generator are coupled by planetary gear sets, and the motor, motor controller, vehicle controller and gearbox are highly integrated. It has the characteristics of compact structure, energy saving, high efficiency, smoothness and sensitivity, and the maximum output torque can reach 5000Nm. Among them, both generator and motor are developed by Ford, and flat wire winding technology is adopted. The slot full rate exceeds 60% and the efficiency reaches 96.2%. With the oil cooling technology of frequency conversion electronic oil pump, the motor speed can reach 17000rpm, the driving motor output power is 140kW, and the torque reaches 320Nm.

The new low-nickel NCM111 ternary lithium water-cooled battery pack comes from BYD. It adopts an integrated high-efficiency water-cooled system, which not only has excellent heat dissipation performance, low risk of thermal diffusion, but also has a long cycle life. It has passed many rigorous tests exceeding national standards such as overcharge, acupuncture, seawater immersion, salt spray, drop, high and low temperature impact and cycle life, and can maintain the normal and safe operation of the battery under extreme conditions. Even at low temperature in winter, the battery pack of the hybrid system can cooperate with the new generation of EcoBoost twin-vortex turbocharged engine to realize continuous and stable automatic charging and discharging.

During the driving process, the whole system can be freely switched between pure electric drive, hybrid drive and electric assist. When various modes are switched, the NVH of the whole vehicle will be very natural. Even when the engine is started or accelerated with a large throttle, the driver and passenger will not feel the sharp attack of noise and vibration after the engine is started, but can only vaguely hear the noise with coarse particles when the engine is running.

DSC_0248

The dynamic performance of the whole vehicle takes into account responsiveness and smoothness. However, in the power connection at the moment when the engine is involved, there will be a rush feeling dragged by the power. Although it is small, the ride comfort needs to be improved compared with Toyota’s hybrid system.

DSC_9594

It is worth mentioning that the vehicle control system accurately calculates the optimal efficiency of the engine and motor, and automatically matches the optimal driving mode according to the actual working conditions, so that the hybrid power system always runs in the optimal efficiency interval. Considering the total mileage of 800 kilometers in urban areas, highways and suburban mountain roads, the average fuel consumption reaches 8.4L/100km, of which 188.5km is for pure electric driving. For a hybrid SUV, this fuel consumption may not be the most fuel-efficient, but considering its power performance and 5 meters.

DSC_0108

Except for the engine, the most obvious difference between Ford’s power splitting technology and Toyota THS is the four-wheel drive system. In Toyota THS, the E-Four four-wheel drive system is adopted, that is, the engine and the driving motor drive the front wheels, and the driving motor located at the rear axle drives the rear wheels. There is no transmission shaft between the front and rear axles, and the power distribution is automatically controlled by the electronic control system. In the Ford Sharp L 2.0T EcoBoost E- hybrid, there is a transmission shaft leading from the output end of the hybrid system to the rear axle, realizing a real four-wheel drive system, which not only can bear higher load and bring better four-wheel drive performance, but also takes into account fuel economy.

Analysis on the Quotation and Configuration Parameters of Volkswagen LaVida

The new generation is the first production car with the latest design language. The iconic transverse grille has evolved again, and the proportion has increased, which is better integrated with the headlights. The overall shape has undergone a subversive change compared with the cash. It has become the mainstream configuration trend of new cars, but at the same time, models equipped with lenses are rare at this level. Even some luxury products are not equipped with lenses, so the new generation’s high demand for details is worthy of recognition.

  The new generation adopts the latest design language in appearance. Compared with the current models, the iconic transverse grille on the front face is larger in area, which is matched with the headlights on both sides to enhance the visual width of the front face. The whole system comes standard with lens type and is equipped with steering assist function, which has a very good effect after lighting. The length, width and height of the new generation are 4670/1806/1474mm and 2688mm respectively. Under normal circumstances, the luggage compartment has a volume of 510L, which is standard and functional. The seat is still electrically adjustable in the main driver’s seat and manually adjustable in the co-pilot seat.

  In terms of interior, the new generation continues the design style of the current model. The three-spoke multi-function steering wheel is still a familiar shape, with moderate size and good feel. The multi-function buttons integrated on both sides also provide good convenience. The classic layout design is still adopted, which brings better usability. In addition, the new generation is equipped with 6.5-inch and 8-inch central control panels according to different models, and it also supports many functions internally, making it more versatile to operate.

  In terms of power, the new generation is equipped with 1.4T and 1.5L naturally aspirated models, including 1.4T110kW(150Ps)/4800-5200rpm, 250Nm/1750-3000rpm; 1.5L85kW(116Ps)/6000rpm,150Nm/4000rpm。 In terms of transmission, the 7-speed dual clutch, 5-speed manual and 6-speed manual are matched with the start.

BJ60/Haval H9/Tank 500/Highlander Review! Who is the "City King"?

BJ60/Haval H9/Tank 500/Highlander horizontal comment on who is the city wild king - Figure 1

"Cross-border life" is a very hot topic in recent years. Getting rid of the two-point and one-line life state and experiencing a different way of living is the best way to redeem the suppressed body and soul.

And off-road is the easiest cross-border life for most of us to achieve, and it is also the easiest to come into contact with. In the past, "old guns" such as Pajero, Paladin, and Prado may have been the choice of more people. But off-road is not the whole of life after all, and the car itself still has to play a role in improving the quality of life. Therefore, Haval H9, Tank 500, Highlander and other attributes that combine both urban and off-road will be more popular.

Recently, Beijing Cross-Country, known as the "off-road family", has launched a blockbuster model – BJ60, which adds new options to this market segment, but also makes it more difficult for consumers to choose. Therefore, we have found the 2022 BJ60 2.0T 11th Edition priced at 279,800 yuan, the 2022 Haval H9 2.0T gasoline four-wheel drive exclusive model priced at 261,800 yuan, the 2022 tank 500 3.0T sports version with a price of 355,000 yuan, and the 2022 Highlander dual-engine 2.5L four-wheel drive premium version priced at 329,800 yuan. Conduct a horizontal review and comparison of these four models to see who is the most worthy of starting.

Appearance represents combat effectiveness

BJ60/Haval H9/Tank 500/Highlander horizontal comment on who is the city wild king - picture 2

The front face of the BJ60 is square, and the unique three-hole air intake grille is integrated with the LED headlight groups on both sides to form a five-hole layout, which makes the front face more hardcore. The built-in LED light strip also has interactive lights, which is more in line with fashion trends. The wide front surround below makes the front of the car more robust, and the circular LED daytime running lights on both sides also combine fog lights to increase practicality.

Haval H9’s front face shape is more traditional. The large-area chrome-plated straight waterfall air intake grille in the middle is full of momentum, and the headlights on both sides are connected to it, adding a sense of stability. The front surrounding design below is relatively full, and fog lamp groups are also added on both sides.

The front face of the tank 500 is equipped with a large-size dense-spoke chrome-plated air intake grille, which is matched with LED headlight sets on both sides to create a strong sense of oppression visually. The front surrounding below is also integrated with fog lamp sets, which enriches the layered feel of the front of the car.

The front face of Highlander is relatively more domestic, equipped with a black trapezoidal air intake grille in the middle, and the narrow LED headlight groups on both sides and the fog lamp areas on both sides of the lower front surround the contour to form an "X" layout, making the entire front face more visually aggressive.

BJ60/Haval H9/Tank 500/Highlander horizontal comment on who is the city wild king - Figure 3

The side shape of the body of the BJ60 is stretched, and the full body lines and the prominent wheel arches at the front and rear are very powerful. The 20-inch wheel hub with yellow brake calipers shows the sportiness. The minimum ground clearance of 215mm and the approach angle of 30 ° and the departure angle of 24 ° provided by the non-load-bearing body lay the foundation for excellent off-road quality.

The side of the Haval H9 is a more attractive type, with the rising window line and waist line creating a swooping body posture, and the 18-inch wheel hub ensuring the thickness of the tire wall. The same non-load-bearing body has a minimum ground clearance of 206mm, a 28 ° approach angle and a 23 ° departure angle.

The side shape of the tank 500 is actually similar to that of the BJ60. The full lines and the square body are very safe, and the 19-inch chrome wheel hub shape is very delicate. It also uses a non-load body, with a minimum ground clearance of 224mm, an approach angle of 29.6 °, and a departure angle of 24 °.

The sides of the Highlander’s body are sleek, the floating roof is rich in fashion elements, the lines on the door panels outline the dynamic posture, and the 20-inch spoke wheels are embellished with some refinement. It is the only load-bearing body structure of the four cars, so the approach angle is only 18 degrees, and the departure angle is 22 degrees.

BJ60/Haval H9/Tank 500/Highlander horizontal comment on who is the city wild king - Figure 4

The rear of the BJ60 is equipped with a side-open rear tailgate and an external spare tire that are common on hardcore off-road. The taillights on both sides are designed to echo the headlights, and the three-dimensional shape is not only exquisite, but also very recognizable.

The rear of the Haval H9 also features a side-opening rear tailgate and an external spare tire. The strip taillights on both sides are not very good in texture, but they still have a good recognition.

The rear of the Tank 500 is also equipped with a side-opening tailgate, but if you want an external spare tire, you need to choose a sports version. The rectangular taillight sets on both sides are more refined in design than the Haval H9.

The Highlander does not use a side-opening rear tailgate, and the shape of its taillight group and the reflective strip design on the rear surround echo the front face. From this, it seems that Highlander is more inclined to the positioning of urban SUVs.

BJ60/Haval H9/Tank 500/Highlander horizontal comment on who is the city wild king - picture 5

Comparing the size of the four models, it can be seen that the body length, width and height of the BJ60 are comprehensively ahead of the other three models. The larger body is not only more in line with people’s aesthetic pursuit of "big cars", but also lays an excellent foundation for the large space in the car. Of course, the wheelbase between Haval H9 and Tank 500 also gives the BJ60 a larger passing angle, which is conducive to improving off-road performance.

By comparing the appearance of the four cars, it can be seen that the BJ60, while absorbing classic and trendy design elements, maintains the style of a hardcore off-road SUV, and paves the way for ride space and off-road performance with excellent size advantages and passability parameters.

Space determines comfort

BJ60/Haval H9/Tank 500/Highlander horizontal comment on who is the city wild king - Figure 6

The BJ60’s interior is designed in a minimalist style, with plenty of straight lines and chamfers to create a hard-edged atmosphere to match the appearance. Large areas of two-tone leather wrapped in metallic trim and piano lacquer panels are embellished with luxury. The 10.25-inch full LCD meter, 12.8-inch floating central control screen and button screen reflect the technological elements.

Haval H9’s interior style is as traditional as its appearance, and the symmetrical layout is more visually stable. Although it is also covered with a lot of soft materials, the combination of wood grain trim and metal trim is slightly "greasy". The combination of 7-inch LCD instrument and 12.3-inch central control screen is also in line with the overall tone.

The interior of the Tank 500 is relatively simple, with a large area of wood grain trim and piano paint trim on the center console reflecting a sense of high-end, and the quartz watch in the center further enhances the interior grade. The configuration of 12.3-inch full LCD instrument and 14.6-inch central control screen belongs to the first tier.

The interior of the Highlander echoes the home style of the exterior. The center console uses an asymmetrical layout, the materials are more simple than the previous three, and the concave storage tank is more practical. The combination of a 7-inch LCD meter and a 12.3-inch central control screen is also slightly inferior.

BJ60/Haval H9/Tank 500/Highlander horizontal comment on who is the city wild king - picture 7

The BJ60 car system has rich functions. In addition to conventional function control, it can also display tire pressure, wading, slope, atmospheric pressure, compass, steering angle, four-wheel drive mode and other off-road information in real time. The configuration of 360 ° panoramic image + 180 ° transparent chassis also reduces blind spots in the field of vision and makes off-road safer. In addition, this car also supports mobile phone interconnection, and has built-in WeChat, Bilibili, iqu, Wi-Fi and other commonly used software, which greatly enhances the convenience of using the car.

Haval H9’s car system has built-in Autonavi map, Douyin, full name Karaoke, iQIYI and other trendy applications. Compared with the BJ60’s professional off-road, it pays more attention to entertainment attributes. In addition, it also has functions such as smart refueling and smart car washing, which is convenient for daily use. The 360 panoramic image it is equipped with also has a good environmental perception.

The vehicle system of the Tank 500 supports function adjustment, car phone, vehicle status display, navigation and other functions. Like the BJ60, it has car Wi-Fi, but does not support mobile phone interconnection. In addition, it is also equipped with 360 ° panoramic image + 180 ° transparent chassis, and the clarity is good, making the off-road process more secure.

Highlander’s car-machine system has got rid of the old style after Baidu’s blessing, and supports Baidu maps, car-home interconnection, smart parking and takeaway services in function, and the convenience has been improved qualitatively. But the only reversing image is not only just passable, but also cannot let the driver grasp the real-time road conditions when off-road.

BJ60/Haval H9/Tank 500/Highlander horizontal comment on who is the city wild king - Figure 8

Thanks to the 1955mm body width, the front seats of the BJ60 can be designed to be very wide. In addition to basic electric adjustment, the main and passenger seats support headrest adjustment, waist support, and are also equipped with heating, ventilation, and massage functions. In addition, the main driver seat also has leg rest adjustment and three sets of seat memory. Both functionality and comfort are comparable to first class seats.

Haval H9 front seats are more compact in size, and also feature electric adjustment, leg rest adjustment, heating, ventilation, and massage, and the main driver’s seat also supports seat memory. Except that the passenger does not support high and low adjustment, it is functionally equivalent to the BJ60.

The front seat of the tank 500 is comparable in size to the BJ60. In terms of function, although the main and passenger seats are equipped with electric adjustment, seat memory, heating, ventilation, and massage, it does not have the functions of headrest adjustment, leg rest adjustment, and passenger waist support. Even if it has little impact on comfort, it will affect passengers to find a comfortable sitting position that suits them to a certain extent.

The front seats of Highlander are not comparable to the first three in terms of size or thickness. Although they all support electric adjustment, they only provide heating and waist support for the main driver in terms of comfort, which is relatively "simple".

BJ60/Haval H9/Tank 500/Highlander horizontal comment on who is the city wild king - picture 9

The rear seats of the BJ60 are visible to the naked eye. The filling not only brings a comfortable sitting feeling, but also has good support for the body and thighs. Functionally, it not only supports backrest adjustment, but also is equipped with heating, ventilation and massage like the front seats. Coupled with the ample legroom brought by the over 5-meter length, it can provide a luxurious riding environment for the rear passengers.

The rear seats of the Haval H9 are also very good in terms of comfort and support, but the middle seat cushion is significantly shorter, which is not very friendly to the middle passenger when three people ride. Functionally support heating, ventilation and backrest adjustment, which is more abundant than the general SUV.

The rear seat of the tank 500 is on par with the BJ60 in terms of work materials, and the wide seat cushion takes care of every passenger. And it functions to support electric adjustment, heating, ventilation, massage, and also has good leg room. Comfort is worthy of the price of 355,000 yuan.

Highlander’s second-row seats, like the front seats, were significantly thinner than the first three, and sacrificed the length of the seat cushion in exchange for legroom. In addition to being adjustable, it did not give any comfort function. In addition, the central platform also had bumps, which affected the comfort of the middle passengers.

Compared with the interiors of these four models, the BJ60 and the Tank 500 are not only more in line with the trend in design, but also better for the creation of luxury. In terms of comfort configuration, the BJ60 seat configuration should be more rich and balanced, and every passenger should be taken care of more thoughtfully.

Configuration to improve driving experience

BJ60/Haval H9/Tank 500/Highlander horizontal comment on who is the city wild king - picture 10

In terms of passive safety configuration, the BJ60 provides the main and auxiliary driver airbags, front and rear side airbags, front and rear exhaust air curtains, tire pressure display, and reminders that the seat belt is not fastened. The tank 500 is consistent with it. On this basis, the Haval H9 reduces the reminder that the seat belt is not fastened to the front seat belt. Highlander instead adds knee airbags on the basis of the BJ60.

BJ60/Haval H9/Tank 500/Highlander horizontal comment on who is the city wild king - Figure 11

In terms of active safety configuration, the BJ60 is equipped with parallel assistance, lane departure warning, lane keeping assistance, road traffic sign recognition, active braking, door opening warning, forward collision warning, and reversing side warning, which can be said to be quite rich. As the most expensive model, the Tank 500 adds rear collision warning compared to the BJ60. Haval H9 is absent from parallel assistance, door opening warning and reversing side warning compared to the BJ60. Compared with the BJ60, Highlander is absent from parallel assistance, road traffic sign recognition, door opening warning and reversing side warning.

In terms of practical configuration, the BJ60, Tank 500, and Highlander all support L2-level auxiliary driving. Based on the difference in active safety configuration, the BJ60 and Tank 500 have a safer and more intelligent auxiliary driving ability with stronger environmental awareness, which effectively reduces the fatigue of driving hard-core off-road SUVs under the premise of ensuring safety. Moreover, the BJ60 and Tank 500 also give automatic parking access, which is undoubtedly a relief for the owner of this kind of "large" SUV that is not easy to park.

In addition, in the sound system, BJ60 and Tank 500 are equipped with 12-speaker Yanfei Lishi audio, Haval H9 also gave 10-speaker Yanfei Lishi audio, can provide a very shocking hearing experience. Highlander is only equipped with 6-speaker ordinary audio, for its 329,800 yuan price, it really should not be.

Compared with the configuration of the four models, the 200,000-level BJ60 is already at the same level as the 300,000-level tank 500, and the rich active and passive safety configuration and L2-level auxiliary driving make travel safe and worry-free, and do not worry about the body size is too large and psychological burden.

In terms of power, the BJ60 is equipped with a 2.0T engine, which can output a maximum power of 196kW and a peak torque of 406N · m after matching the 8AT gearbox. At the same time, a 48V light hybrid system is paired with this powertrain, which not only optimizes the power output smoothness at low speeds and acceleration, but also helps to reduce fuel consumption and improve economy.

Haval H9 is also equipped with a 2.0T engine, which is also equipped with an 8AT gearbox and can output a maximum power of 165kW and a peak torque of 385N · m, which is slightly inferior to the BJ60.

The tank 500 is equipped with a 3.0T V6 engine, matched with a self-developed 9AT gearbox, which can generate a maximum power of 265kW and a peak torque of 500N · m. Like the BJ60, it is also equipped with a 48V light hybrid system, which is mainly used to optimize the fuel economy of this power system.

The Highlander is equipped with a hybrid system composed of a 2.5L engine, matched with an E-CVT gearbox. The maximum power of the engine is 141kW, the peak torque is 238N · m, and the maximum power of the front and rear axle motors is 134kW and 40kW, respectively. The peak torque is 270N · m and 121N · m, respectively. The whole system mainly emphasizes economy.

Compared with the power systems of these vehicles, the Tank 500, as the only model equipped with a 6-cylinder engine, is undoubtedly the most powerful, but it corresponds to higher fuel consumption. In the 2.0T camp, the BJ60 is obviously more powerful than the Haval H9, and with 48V light hybrid escort, fuel consumption is also guaranteed. Highlander is the only model equipped with a hybrid system, which is more suitable for long-distance travel than off-road.

On the off-road side, the BJ60 carries a time-sharing four-wheel drive system with front and rear axle differential locks, the Haval H9 and the Tank 500 are both equipped with timely four-wheel drive systems with rear axle differential locks, and the Highlander is equipped with an electric four-wheel drive system. Description out of thin air can only highlight the power of the BJ60 four-wheel drive system. As for which is stronger and which is weaker, we decided to pull these four models to the off-road venue for a walk.

The test section is divided into hump slope which tests climbing ability and cross axis slope which tests escaping ability.

The first is the BJ60, after hanging up the 4H (high-speed four-wheel drive) gear, under the impetus of 406N · m torque, it passes through the hump slope without pressure. The next cross-shaft slope quickly escapes after the left rear wheel idles briefly, without using any differential locks during this period.

Haval H9 suddenly had a tendency to lack grip at the front end of the hump slope, but the system quickly switched to four-wheel drive mode to continue climbing, and then passed smoothly. After entering the intersection shaft, the left front wheel with adhesion was obviously not strong enough, but fortunately the rear axle differential quickly locked and pushed the vehicle through.

The tank 500 is the same as the Haval H9 in four-wheel drive configuration, and theoretically the passing state of the two is similar, but its 3.0T V6 engine is more abundant in power reserve, and the movement through these two sections is obviously easier than that of the Haval H9.

Due to the lack of a truly rigid four-wheel drive structure, Highlander’s electric four-wheel drive system relies entirely on the front and rear axle motors, so it failed in the hump slope section due to insufficient motor torque and motor protection. It was the only model among the four models that failed the test.

Through actual field tests, we can see that the BJ60 is a handlebar for this type of conventional off-road terrain, without the need to open the front and rear axle differential lock at all, and the off-road performance cannot be underestimated. In addition, it also has 9 ATS family-level global control modes and 12-speed intelligent creep mode, which is enough to prove the strong off-road potential of the BJ60.

Summarize:

Through the cross-review comparison of these four vehicles, we can see that the three self-owned brand models of BJ60, Haval H9 and Tank 500 are stronger than Toyota Highlander in terms of size, comfort and off-road performance, and can better be compatible with both urban and off-road living conditions. Among them, the BJ60 and Tank 500 have improved the quality of "cross-border life" to a new dimension with outstanding hardware quality, luxury driving and hard-core off-road functions, but combined with the lower price of the BJ60, it is undoubtedly more cost-effective. Therefore, if you want to buy a city off-road SUV at this stage, the BJ60 will be a better choice.
