The engine "burning oil" means that the oil enters the combustion chamber of the engine and participates in the combustion together with the mixture. "Burning oil" will lead to engine performance degradation, excessive emissions, engine mechanical damage, and excessive oil consumption. Tell us about the danger of oil burning
The burning of engine oil can be divided into three situations: burning engine oil when the car is cold, burning engine oil when accelerating, and burning engine oil in any case. In any case, oil burning is the most serious, and the engine needs to be overhauled, otherwise it is easy to cause accidents.
Burn engine oil when cooling the car
When the excavator is started for the first time in the morning, strong blue smoke will be emitted from the rear air pipe. After a period of time, the blue smoke disappears, and there will be no similar situation on that day. A similar problem occurred the next day when the excavator was started. It is understood that this is due to the aging and severe wear of the valve oil seal, which can not achieve a good sealing effect. When the engine is not running for one night, the oil will flow into the cylinder through the valve stem seal due to gravity. Once the engine is started, the oil in the cylinder burns under the action of high temperature and pressure to produce a large amount of blue smoke.
Oil burning during acceleration
Burning engine oil during acceleration means that a large amount of blue smoke will be discharged from the exhaust pipe when the vehicle is moving, such as stepping on the accelerator or landing on the ground and stepping on the accelerator. In serious cases, you can see blue smoke from the reflector on the side of the exhaust pipe after stepping on the accelerator. This is because the sealing between the piston ring on the engine piston and the cylinder wall is not tight, and the engine oil jumps directly from the crankcase into the cylinder during rapid acceleration, resulting in engine oil burning.
Burn engine oil under any circumstances
In any case, engine oil is burned, which is the most serious case of engine oil burning. This situation indicates that the engine has been seriously worn and needs to be overhauled, otherwise serious accidents will be caused.
So at the end of the article, we remind you again that once a large component fails, we should first be careful and not miss any small details, so as to fundamentally solve the problem.
