China's automobile industry started late, and the initial development mainly relied on imitation and borrowing foreign products. Japanese engines have won numerous awards internationally for their economic and fuel-saving characteristics, and Japanese engines have become the object of imitation of domestic cars.
How strong are Japanese engines? More than a decade ago, Honda had a 1.8-liter naturally aspirated engine, which is economical and fuel-efficient, and has a super high level of power output, stability and tranquility. At that time, domestic brands dismantled many Japanese engines and gained experience by studying the principles and technologies of Japanese engines, but domestic brands have never imitated engines as powerful as Japanese engines.
Domestic car companies cannot imitate Japanese engines, mainly because of the protection of technical barriers. Japanese car companies have applied for many technology patents for engines, and domestic brands cannot bypass these patents and directly use other people's technologies.
Japanese engines also use a set of standardized assembly line production platform, domestic car companies want to imitate the exact same Japanese engine must create a complete production line, which will increase cost input, domestic brands are not willing to try.
Domestic brands imitate Japanese brands for so long, what have they learned?
In the past, the power of domestic engines was weak and the stability was not strong, but now domestic brands have been able to achieve breakthroughs in data such as engine book power horsepower by imitating Japanese engines. The data of the engine on the horsepower machine test is also good, but in the real use process, many car owners will complain that the engine noise is too large, the fuel consumption is too high, and it is not as good as the book data.
In the past, domestic brands could not develop their own engines, and all engines had to rely on imports from abroad. Now domestic brands have the strength of independent research and development, but the technology of research and development is lacking.
Domestic brands can be stronger than Japanese engines in terms of engine power horsepower parameters and explosiveness, but there is still a huge gap between them and Japanese engines. The Japanese engines are perfect, not only stable, economical and fuel-efficient, but also ensure low noise and high durability. Domestic engines are not yet comprehensive, so many car owners feel that domestic cars are not easy to drive.
Researching the engine is a long process, and at present, domestic brands have taken the lead in power parameters. Domestic brands want to continue to catch up with Japanese engines, and surpass Japanese engines, it will take a lot of time, I hope we can be more tolerant of domestic brands.
Although the achievements of domestic brands in the internal combustion engine are not as good as Japanese engines, domestic brands have achieved good results in motors in the field of new energy. BYD's electric vehicles are better than Japanese pure electric vehicles in terms of range, power explosion and acceleration.
The starting road of domestic engines is extremely difficult, before we did not have the strength to build engines, we can only remove the parts of other engines to study, through imitation of the original imitation. In the process of imitation, Chinese car companies have laid a solid foundation, and now the engine independently developed by domestic brands has made great progress in durability and power parameters.
The next step of domestic car companies is to reduce the noise of the engine, improve the fuel economy of the engine, and believe that one day the domestic engine will be able to go abroad and go to the world.
