What is the reason for the serious combustion of automobile oil?

1, the automobile valve oil seal is not sealed. The owner starts the car when the engine temperature of the car does not reach the normal driving temperature. At this time, it is easy to see the blue smoke from the exhaust pipe of the car, but the exhaust will return to normal after a while. This is because when the temperature is relatively low, the valve oil seal of the automobile cannot be completely sealed, and the oil enters the combustion chamber from the valve, and then the oil will burn.

2. The automobile piston ring is not well sealed. If the car still burns oil after reaching normal temperature, it may be that there is something wrong with the piston ring of the car and the seal is not good. The sealing ring leaks oil, the oil enters the combustion chamber, and then the car will burn the oil and emit blue smoke. There are several reasons why automobile sealing rings are not sealed, such as aging of sealing ring materials, carbon stuck in automobile sealing mouth, and serious wear of automobile cylinder liners.
