Honestly, an editor is a person who likes to talk to professionals because it is a free and practical source of knowledge and you can hear a lot of interesting things, for example, many domestic car repairs and many Japanese auto repairmen think that Japanese engines are better than domestic , Yes?
Then I kept asking. The engine failure rate of Japanese cars is low, which all maintenance technicians admit. However, I will still leave some opinions. Because Nissan burns motor oil, Subaru burns motor oil, Honda makes motor oil, etc. However, most Japanese engines are good, especially constant pursuit of fuel consumption, which is really admirable.
Although Japan is a small island country, it is a world leader in mechanical engineering and one of best metal smelting technologies. Japan's application of this engine technology and materials already means that Japanese engines will be With development of science and technology in past two years, Japanese cars have mastered their own core technologies, making engine reach a level of precision. Everyone knows that material of engine is mainly steel, and The maintenance master said to editors,Japan's metallurgy is known all over world. Naturally, material of domestically produced engines is not as good as that of Japan, so engines of Japanese cars can be operated for many years without abnormal noise and vibration. Japan imports its engines to match.
And if it is said that buyers use cars, many people choose Japanese cars first, this is because Japanese cars are more suitable for engines than German cars, although power and performance of Japanese cars are not so good. like German cars, but in terms of fuel consumption, advantage is far ahead of German cars, and in terms of price, they will also have an advantage over German cars. Some old drivers said that although many people are impressed, overall quality of German cars is better than Japanese cars. , but as for engine, perhaps Japanese engine is better. The German engine is built into mesh on cylinder wall. Compared to flat cylinder wall, Japanese engine, German engine The movement of engine piston does not completely remove oil, leaving residue on cylinder wall of automobile engine, so cost after maintenance, both are higher than German engine.
Finally, it is very difficult to learn engine technology, Japanese are willing to delve into this issue, but some domestic companies do not have research on this issue, and some domestic businessmen do not care, only thinking profits, and making this thing is very troublesome. To study it takes a lot of time to perfect it, and it also requires very subtle technology and people's patience. Chinese manufacturers simply do not have such patience, Japanese auto companies value long-term savings, and some domestic cars only care about momentary interests, so there is a saying that domestic engines are lagging behind Japanese ones. Why are domestic engines not as good as Japanese ones? Now that you have listened to the old master's analysis, you should fully understand it.
However, automotive engine technology is a very complex technology supported by a very complete process chain. Regarding technology of automobile production in Germany and Japan, Japan has also inherited and improved technology of automobile production in West, such as Germany. Although Japan currently ranks among best in world in terms of automotive metallurgy, processing and assembly process chains, their technological development was based on World War II, relying on looting of other countries' property as an economic backdrop, and after more than 70 years . development Accumulation of experience has created today's achievements. Although my country's auto industry has almost 60 years of experience, for various reasons it did not get on right track until 1980s of reform and opening up. After almost 30 years of development, it has reached today's progress. I believe that another 30 years will pass, and level of car production in China will also be at forefront of world.
