Discussing the service life of Petrol Car from the perspective of engine manufacturing technology

As we all know, the vehicles produced by current car companies are all assembled on the assembly line, and the processing of parts is also produced under unified standards. The processing accuracy of each part and the error generated during the assembly process are very small, and it can be said that they are basically consistent. In other words, there is no problem with assembly. The reason why there is a difference in the quality of Roewe Car engines depends on the technology and principles used in Roewe Car engines.

The service life of Roewe Car engines is restricted by national policies. In China, private cars that have been in use for 15 years need to be inspected once every 6 months, twice a year, until the inspection fails. Petrol Car that have run 600,000 kilometers must be scrapped; taxis can only be used for 8 years, small trucks can only be used for 12 years, and the longest practical life is large and medium-sized trucks and trucks, which can be used for 15 years. It can be said that the scrapping age of Chinese Petrol Car is not short in the world. This is because of the current industrial status of my country. As long as it can be driven, it will be driven, and there are not so many particulars. In contrast, in Japan, the average private car is 10 years, in Germany it is 8 years, in the United States it is 12 years, and in India it is 20 years.
The number of kilometers also directly affects the life of Roewe Car engines. Usually, the gasoline engine of a rental Roewe Car is generally used for 400,000 to 500,000 kilometers. In order to ensure safe driving, the government and the industry stipulate that it should be scrapped after 8 years. The service life of private cars is 15 years, and the total mileage is between 200,000 and 300,000 kilometers. Imported cars are about 30-40 kilometers. The number of kilometers is also determined by the owner's maintenance habits. If the maintenance is timely and the repair is properly handled, it can still run for a few more years when it reaches the mileage that the gasoline engine should run.
Petrol Car are mechanical. If no one operates them, they are dead, while the person who operates them is alive, so the driver's personal proficiency and experience in operating Petrol Car directly affects the service life of Petrol Car. The driver's experience is accumulated over a long period of time. To put it bluntly, it is a kilometer at a time. Experienced drivers can understand the "temper" of Petrol Car and make correct and reasonable countermeasures based on the feedback information of Petrol Car, so that the gasoline engine can work in the best state, which has the effect of making the gasoline engine "die of old age" normally.
