How to assemble the car

Car (Pinyin: chē, jū) is a first-level general standardized Chinese character (commonly used words). This character was first seen in the oracle text and Shang Dynasty script in the Shang Dynasty.

They appeared from the end of the 18th century to the beginning of the 19th century, but they were not widely used and developed due to the shortcomings of slow speed, low efficiency, high cost, loud noise and serious pollution.

And Japan's control on patents and parts is also very strict, each Engine technology has been patented, and many parts use Japanese parts, and such parts will not be sold to other countries at all. Even if China has the strength to imitate successfully, it will be rejected because of the parts.

At that time, he thought that with the speed of China's development, he would not be able to build its own engine even in another 50 years. Unexpectedly, in less than 30 years, a large number of independent brands such as Chery, Great Wall and Geely have their own engine technology, and domestic cars can fully rival any joint venture brand in terms of sales.

The reasons why China cannot build engines mainly include the lack of technological accumulation, the limitations of lack of resources, the difficulty of independent research and development, and the lack of cooperation and innovation.

It is extremely simple to make the same engine. The difficulty lies in the basic science, the material of the engine itself. Yes, you can think of it as steelmaking. China is relatively backward in the field of smelting. Therefore, the development of many industries has been restricted. For example, the smelting technology of the United States is very awesome, but the steel plate of nuclear submarines still needs Swedish technology.

No. It is not that China can't produce high-quality automobile engines, nor can it write engine control programs.

The reason why many people think that we can't make excellent engines by ourselves is largely because our development direction is different from that of foreign countries, which can be said to have their own strengths. For foreign investors, their advantage lies in high-end brand cars, that is, luxury cars driven by rich people.
