Why does Haval h6coupe2.0t burn engine oil?

The engine oil of Pacific Auto Network burned 1, and the piston ring groove was seriously worn. The oil lubricating the piston escapes to the combustion chamber to participate in combustion, because the piston ring is not tightly sealed. 2. The oil seal of the valve is damaged, and the oil lubricating the camshaft enters the combustion chamber through the valve to participate in combustion. 3. The crankcase in the forced ventilation system is faulty.

Haval h6 has engine oil burning. If it is used for a long time, you can choose to use engine oil with relatively high viscosity to increase the sealing between the engine piston and the cylinder wall. In addition, check the oil gauge frequently and change the oil and oil filter regularly. If the problem of burning oil is serious, it is best to go to a repair shop to check, repair the engine or replace it with new parts.

Automobile engine oil combustion means that the engine oil rushes into the engine combustion chamber and the mixed gas participates in the combustion. The combustion of automobile engine oil will lead to the increase of carbon deposition in the combustion chamber, unstable idle speed, weak engine acceleration, increased fuel consumption and damage to the accelerated oxygen sensor. In severe cases, it will lead to insufficient lubrication, serious wear and tear, increased maintenance costs and even scrapping of the engine.

Reasons for oil burning:

1, the piston ring groove is seriously worn, and the oil lubricating the piston rushes into the combustion chamber to participate in combustion because the piston ring seal is not tight.

2. The oil seal of the valve is damaged, and the oil lubricating the camshaft enters the combustion chamber through the valve to participate in combustion.

3. The crankcase forced ventilation system is faulty. During the operation of the engine, a small amount of high temperature and high pressure gas escapes from the piston ring into the crankcase. With the increase of temperature in the crankcase, gas expands, high-temperature and high-pressure gas escapes into the crankcase, and the pressure in the crankcase increases, and the oil will leak from the joint surface and oil seal.
