The engine is the most core component of the car, and it is very necessary for a car company to have its own engine technology if it wants to achieve long-term development. The engine technology of Japanese cars is obvious to all, and it is second to none in the automotive industry, and the early Mitsubishi engine and later honda earth dream are at the forefront of the world.
Domestic cars started late and have always been the image of "inferior technology" in terms of engine technology. In the early development process, domestic cars can only produce their own engines by dismantling other people's engines, and then producing their own engines through imitation and debugging. Since the 1960s and 1970s, domestic cars have embarked on the road of reverse research and development, and Japanese engines have been dismantled by thousands, but they have not been able to imitate Japanese engines.
Many people think that this is because Japan's engine technology is too good, they have their own engine patents protected very well, although we can take apart other people's engines, we can also see the structure inside, but the proportion of parts is not known, even if it is copied out of proportion, adjust different performance is also very different.
There is nothing wrong with this idea, any car company has a protection mechanism for its own invention patents. The reason why Japanese cars can sell well all over the world, but they are not at all worried about their engine technology being leaked, is because their protection mechanism is very perfect, all the parts that can be patented have been patented, if someone dares to imitate their engine, these patents are their weapons.
Japanese cars have a history of nearly 100 years to this day, and they have a strong historical background in automobile manufacturing. Although Japanese cars were initially developed by imitation, in the later development process, they explored their own path, and the engines used in the cars used were advanced technologies developed by themselves in the later stages.
If you do not understand the principle of the engine or do not understand the processing technology of the parts, even if the parts of the engine are imitated in accordance with the ratio of 1:1, it is another engine after assembly, rather than the one that imitates itself.
In the process of imitation, the independent brand also imitated the Japanese engine according to the ratio of 1:1, but the final result failed. Because they found that although they assembled the parts in proportion, because of the different tuning methods and assembly processes, the final engine performance was much worse than the original engine.
And they found that the assembly environment of Japanese engines is also different, which is an important factor affecting the performance of the engine, they will heat treat the parts after machining, this step is related to the service life of each part, it has also become a difficult link for many independent brands.
As one of the three most important parts of the car, engine technology for every car company has a vital significance, although in the process of reverse research and development, independent brands suffered a lot of losses, but through their own unremitting efforts, finally developed a path of their own.
Many first-line independent brands have produced their own engines through independent research and development, although there are still some gaps in the stability and durability of these engines compared with Japanese engines, but at least in terms of independent research and development has taken a big step, it is still very worthy of recognition.
