A change in the status of imported cars and joint venture vehicles dominates the market. Nowadays, in China's domestic auto market, the voice of domestic cars is also growing. Especially in the SUV market, domestic vehicles such as Haval H6 have suppressed many imported cars. With joint venture car. The sales volume is large, and the reputation of domestic cars is also large. The popularity of Haval H6, etc. is not even lower than that of modern Toyota cars. With fame, many domestic cars sold well and they were hailed as Chinese.

Domestic cars have developed in full swing, gaining fame and fortune. However, domestically-produced vehicles also suffer from consumer complaints, which means that they cannot produce excellent engines. The engines used by domestic cars are not purchased directly from foreign countries, but are foreign ones. This kind of shanzhai is not copied, but it is studied in reverse. For example, the Haval H6 has a world-leading engine and is also a cottage Honda engine.

Well-made domestic cars, manufacturers also have money, but why not produce a good engine? For most people, this is caused by the following reasons.

Metal casting process behind

The cylinder body of the engine is cast from metal, and the metal is generally cast iron or cast aluminum. However, China does not produce high-quality cast iron and cast aluminum. Without high-quality raw materials, it can only be imported. This burdens auto manufacturers too much.

Machinery processing equipment imported

With high-quality raw materials, in order to produce excellent engines, sophisticated instruments are also needed. High-precision machine tools and precision machine tools need to be purchased from abroad. This cost is also very large.

Lack of good mechanics

With excellent raw materials and machinery, excellent mechanics are needed to produce assembled engines. However, this piece is also lacking in China, and we are too unfocused on the training of senior technicians.

In this way, the cost of producing a good engine is more expensive than direct purchase. Manufacturers obviously do not want to do it themselves. In addition, the production of excellent engines also requires advanced technology, and foreign companies are reluctant to sell to us, but instead engage in technical blockades, because only in this way can we continue to purchase their engines.

As for independent research and development, domestic manufacturers do not have this interest and they do not have this need. After foreign automakers make profits by selling cars, they will invest a large part of their revenue in R&D, while domestic manufacturers do not. The Great Wall rolled through the Haval H6, but they were very awkward in R&D. This is because since the cottage engine can sell well, why bother to study new ones? In fact, the vast majority of domestic cars are the same, which has created a domestic car to work hard on the appearance, but in the engine and other core components do not seek progress.

The production of an excellent engine cannot be blamed. We blame ourselves and engage in research rather than the so-called technical blockade. This reason is very heartfelt, but it is also an objective fact.
