How often is the engine cleaned?

Under normal circumstances, it usually takes 30,000-50,000 kilometers.

Because the engine works under high temperature and high pressure for a long time, sludge and carbon deposit will reduce the efficiency of the engine, which is very necessary for old cars with a certain age. Cleaning the lubrication system, air intake, combustion chamber and other items is necessary to maintain the automobile engine.

Extended data:

The engine is the power source of the car. Automobile engines are mostly thermal devices, referred to as heat engines. The heat engine converts the heat energy generated by fuel combustion into mechanical energy through the state change of the working medium.

1967, the United States held a public performance of a hydrogen-powered car, which was charged with hydrogen at a speed of 80 km/h and could run 12 1 km each time. The car had 19 seats and was made by Billings Company of the United States.

1983, the world's first car with a diesel ceramic engine was successfully tested. The engine is developed by Kyoto Ceramics Company of Japan, and its main components are made of ceramics, which saves the cooling system, is light in weight, and has remarkable energy-saving effect. Under the same conditions, it runs 30% more than the conventional engine.
