The engine is the heart of the car. It is precisely because of this importance that many people will pay extra attention to the state of the engine, both when buying a car and after buying a car. But to ask how long the life of an engine lasts, this is hard to say, because in terms of mileage and time, the world has more than 4 million kilometers of cars and cars that have been in use for more than 50 years.

Because the engine is a part of extreme working conditions, which determines its need for excellent maintenance measures, such as the first thought of the oil, regularly replaced with the wear of engine wear debris, can improve the internal cleanliness of the engine. For engines with complex operating conditions, the length of life is determined by the user and the environment. External factors account for a large part.

Let us first look at the relevant policy requirements. In China, private cars run for 15 years and need to be checked once every 6 months, twice a year, until the inspection fails. Vehicles that have already flown 600,000 kilometers are unconditionally scrapped; taxis can only be used for 8 years, small trucks are 12 years old, and the maximum age is medium and large trucks and trucks, which can be used for 15 years. Cars driving 600,000 kilometers will lead to scrapping. Therefore, the average engine is about 15 years, and the better one can reach 20 years.

In fact, the number of years spent on Chinese cars is not too short in the world. Generally speaking, the more prosperous countries in the auto industry are, the shorter the number of years of retirement will be, and the longer the country will become obsolete, the longer it will be. The average private car in Japan is 10 years, in Germany it is 8 years, in the United States it is 12 years, in India it is 20 years, and South Korea is the most special. Private cars have no years of invalidity. They are forced to be revoked when they fail to pass inspections, but they are very strict with units and groups. The car will be abandoned in 3 years.

It is difficult to measure the life of an automobile engine simply by mileage or number of years. Generally, the engine has a design life. However, the design life does not mean that the engine cannot be used. As long as the daily maintenance is emphasized, the actual life can be very long.

Under normal circumstances, the general engine is used for about 15 years. If it is well maintained, it can be opened up to 20 years and the number of kilometers can reach more than 600,000 kilometers. If the maintenance is not in place, the condition of the vehicle will be worse. In 10 years, you will Do not want to open.
