Speaking of engines, this is definitely one of the three things that people pay most attention to when buying a car. Although South Korean auto start is later than China, they now attach more importance to R&; D and operation, but also has a mature and reliable gearbox research and development capabilities. Their engine technology has entered the top ten engines in the world. Although domestic cars such as Chery and BYD have their own engines and gearboxes, most of them are still using engines eliminated by Japanese cars. Although BYD is at the world leading level in electronic control technology, other aspects of other car companies need to be improved. Korean car engines basically follow Kia's American route and modern Japanese route. Korean automobile engines are basically imported from abroad and independently improved, ranking behind Japanese engines and before domestic engines, but the quality of Korean automobile engines is slightly better than that of domestic automobile engines of the same level. The other is to consider economic fuel consumption.

For example, KIA's CVVT engine focuses on fuel-saving routes. Take modern Elantra as an example. It uses 1.6L and 1.8L engines, but both have been recalibrated. 1.6L adopts modern α-CVVT engine with maximum power of 82kW/6000rpm and maximum torque of 145. 1Nm/4500rpm. 60km/h and 100km/h, the acceleration time is 0~60km/h, the acceleration time is 6 seconds, and the acceleration time is 0~ 100km/h 12.5 seconds. It can be seen that the initial acceleration performance of Elantra is still very good.

1.8L adopts modern β-DOHC engine. This engine can release the maximum power of 96kW at 6000 rpm and the maximum torque of 162N at 4500 rpm. The application of CVVT technology not only improves the engine power, but also improves the fuel utilization rate, thus reducing fuel consumption and emissions. The fuel consumption of the engine can be reduced by more than 14 percentage points. Elantra's engine is supplemented by a newly adjusted 5-speed manual gearbox and a 4-speed automatic gearbox, achieving the goal of saving 8% fuel. The advantages of Korean engines are easy maintenance, no major problems and low fuel consumption.

When it comes to domestic independent brand engines, you have to say Chery. Chery ACTECO engine is divided into three series: small displacement (3 cylinders 0.8 to 4 cylinders 1.3 liters) gasoline engine series; The series of medium and large displacement (4 cylinders 1.6L to V84.0L) and diesel engines (3 cylinders 1.3L to V62.9L) mark the' zero' breakthrough of Chinese people in the new generation of high-performance automobile engines, and create a precedent for the development and manufacture of high-performance independent brand engines. Chery ACTECO engine adopts a large number of contemporary most advanced technologies, and its technology integration is in the leading position in the world, and its main technical indicators such as power, fuel consumption and emissions have been achieved.

In short, domestic independent brands still have a long way to go. Only pay attention to the research and development of core technologies and appearance design, and don't just rely on vacancy, configuration and price. In order to get one or two hot sales, because everyone is still paying attention to three big pieces as the core content.

Yuan Chao Xiao Li:

Is autonomy really comparable to that of Koreans?

This problem is divided into two parts. One is who is stronger than the mainstream Korean cars in the market, and the other is how big the technical strength gap is. Let's talk about a bad thing first, that is, there is a big gap between the two in technical strength.

Safety test

What is the technology that is closely related to us and what is the most important for everyone? Of course it's safe! In terms of safety, Korean cars can get very high scores in the same class, whether it is China's C-NCAP or E-NCAP test, or even the extremely strict American IIHS test, but what about autonomous cars? First of all, few self-driving cars take part in the electronic NCAP test. In the impression of the technical house, only Qoros 3 scored 5 stars in the E-NCAP test, and that was the collision rule before the revision (even Ford Mustang can only score 2 stars under the new regulations today). Of course, our own cars are rarely sold to Europe and America, mainly to countries with underdeveloped automobile industries such as India, Russia and the Middle East.

Some people are not convinced. How many self-driving cars have won five stars on our C-NCAP? Isn't this proof of strength? Hehe, I can't help it if you say so. Just look at how difficult E-NCAP's C-NCAP project is.

Electric power technology

Gearbox with engine

The second is the power system. Hyundai started to establish a research center in 1984 to independently develop engines and transmissions. 199 1 developed the alpha engine and transmission, which is the first independent technology of modern cars. So far, Hyundai is one of the three automobile manufacturers in the world who have successfully developed a six-speed transmission. Other models, such as China H3/ Southeast DX7, also bought modern 5AT transmission. At present, there are only a handful of car companies that independently develop gearboxes. Chery's CVT counts as one, and BYD's dual clutch counts as one (although it comes from the opposite direction).

The autonomous vehicle has no six-cylinder engine except Borui's 3.5LV6, and the modern six-cylinder engine has been installed on the old Tucson and Lion Run. At that time, the only self-driving car we remember seemed to be Haval CUV? In 2008, Hyundai has developed a V8 engine with a displacement of 4.6L, with a maximum horsepower of 366 horsepower, which is mounted on the modern large luxury car Equus. By the way, Equus is a modern model at the same level as BMW 7 Series.

Make luxury cars

Building high-end cars is also a place that can reflect the gap. Why did Volkswagen make great efforts to build Phaeton? Although the sales volume has been poor since its birth, it has been discontinued now. Perhaps the public has long anticipated this ending, but why build it? There is a simple reason. Only powerful manufacturers can make a car like Phaeton. You see, I was made by the public, awesome?

What high-end cars do we own? Except for the mythical models of state-owned enterprises, there are no high-end models, but there are Equus in modern times. Yakeshi can not only show its own strength, but also be a high-end reception car purchased by the government, and it is also a moment to show its national image. And the official cars in our country are mostly Audi A6L and BMW 7 Series! Why are there no self-driving cars? For this reason, BAIC has developed BJ90, a high-end car (not yet listed), which will be the focus of national procurement in the future, but it uses the chassis and engine gearbox of the old Mercedes-Benz GL.

Liu heard that:

With the help of Japanese engines, Korean engines gradually began to independently develop and manufacture through their own research and accumulation.

Before 1990s, there were two kinds of Korean cars. One is to cooperate with Japanese car companies to sell Japanese cars in Korea by OEM. The whole set of technology is provided by Japan. The other is to design and manufacture their own cars, but use the power system and transmission system provided by Japanese companies.

In the process of cooperation with Japanese companies, Korean auto companies constantly learn from each other's advanced technology in engine and transmission system, and constantly replace some Japanese parts with some self-developed parts on their own models. In the mid-1990s, Korean cars began to introduce self-developed power transmission systems.

The current Korean engine is not much different from other mainstream cars in the world in basic technology. Only the material technology is not as developed as American cars, and the application of some advanced materials is slightly inferior to American cars; The application of advanced technology is not better than the European system; The technology accumulation of hybrid power and new energy is not as good as that of Japanese companies such as Toyota Honda, but the characteristics of Korean engines are here. Every aspect of it is not the best in its class, but it is not bad.

In short, the Korean engine is balanced in all aspects and the powertrain is reliable.

Your daughter-in-law calls me husband:

It should be said that Korean cars are still developing well. In the early years, we also cooperated with Mitsubishi and Chrysler and absorbed some technologies and R&D; D experience Now, some developed countries in Europe and America have gained a firm foothold. However, our domestic cars have developed by leaps and bounds in recent years, including Geely absorbing some Volvo elements to develop Borui, and the Great Wall reversed Toyota's high-end independent SUV Haval H9, which made Chinese people see the hope of national brands. However, compared with Korean cars that have been going international for many years, there is a certain gap in both mechanical technology and training experience. Of course, if domestic joint-venture Korean cars are another matter, first of all, technical castration is inevitable for joint-venture cars, not only for Korean families, but also for the serious shrinkage of body materials. Most joint venture vehicles use galvanized steel plates with good corrosion resistance on the body parts. But at present, the cars owned by Beijing Hyundai and Da Yue Kia are all ordinary annealed steel plates. You can check Baidu to see how many car owners have complained about this. Besides, A-pillar and B-pillar and other parts of sheet metal are spliced together. If you don't tell the accident, it's easy for you to make a little noise during your daily driving. Therefore, I personally suggest that 65,438+00,200,000 ordinary family cars need not consider any joint venture cars now. Of course, this point should not be too subjective according to personal preferences. Korean power output and humanized design in the car are well received by car owners.

Korean car owners are mainly Hyundai and Kia brands. Like Cerrato Elantra, Freddy Elantra, K2 Rena, K4- Mingtu, K5- Sonata Nine, Lion Run-Tucson, Smart Run -IX35. KX3-IX25, etc. Among these models, 1.6L, 1.4L, 1.8L, 2.0L, 2.4l (canceled assembly in 2065438+06), 1.6T and 2.0T are all involved. Since its establishment in 1967, Hyundai has experienced 24 engines, and 199 1 independently developed engines have been successfully manufactured. 1.6 gamma engine is one of the top ten engines in the world. Engines like KIA Freddy 1.6L have 123 horsepower, which is excellent.

Domestic engines have no comprehensive core technology. Although China's automobile industry has a history of 60 years, and private enterprises have a history of less than 30 years, when the engine is truly independently developed, the accumulation of engine technology is very small. It can only be said that China can build engines, but there is still a long way to go before technological breakthrough.

So at present, the technology of Korean cars is ahead of domestic cars, but I believe that with the efforts of private enterprises, there will be a major breakthrough in China one day.

Young lang in the cracks:

There is no doubt that Korean cars and domestic cars have made great progress in recent years. But to be fair, the domestic technology is far from reaching the level of Korean cars. I may attract many people to scold me for saying this, but what I said is also true. Almost all domestic cars have experienced the process of using the old Mitsubishi engine, some are still in use, and some are so-called reverse research and development. If you want to drive for 56 years, domestic cars can still be used, but the fuel consumption and power are far from each other, and some even don't match the spring parameters. As far as Emgrand and H6, the two best-selling domestic cars, are concerned, there is still a big gap with Korean cars. Some people say that the acceleration is only half a second short of fuel consumption, but how many difficulties must be overcome to achieve it. Why do domestic dual clutches go all out or do it? One is to save costs, and the other is to reduce the so-called fuel consumption. Although Korean cars are not as famous as German cars and Japanese cars, cars like Elantra have completed several life cycles. Look at domestic cars, not to mention Wuling. The oldest domestic car we can see on this road is the Chinese Pentium red flag, which can still be used, but it is really a bit unsatisfactory. We all hope that domestic cars will get better and better, but it is not that the slogan is "The story of domestic cars is good", but that we can really get some successful works and sell them to Germans and Japanese. The sales volume of selling countries depends not only on policy orientation, but also on understanding that China people sell in China.
