Engine "burning engine oil" means that the engine oil enters the combustion chamber of the engine and participates in combustion together with the mixture. "Burning engine oil" will lead to engine performance degradation, excessive emission, engine mechanical damage and excessive consumption of engine oil. Tell us about the harm of the oil burning fault
There are three types of engine oil burning: engine oil burning when the vehicle is cold, engine oil burning when accelerating, and engine oil burning under any circumstances. Among them, oil burning is the most serious in any case, and the engine needs to be overhauled, otherwise it is easy to cause accidents.
Cool the car and burn the engine oil
Burning engine oil means that when the excavator is started for the first time in the morning, there will be relatively thick blue smoke discharged from the rear air pipe. After a period of time, the blue smoke disappears, and generally there will be no similar situation on that day. Similar problems occurred when the excavator was started the next day. It is understood that this is because the valve oil seal is aging and severely worn, and cannot achieve a good sealing effect. When the engine does not run for one night, the oil will flow into the cylinder through the valve oil seal due to gravity. Once the engine is started, the oil in the cylinder burns under the action of high temperature and high pressure to produce a large amount of blue smoke.
Burn engine oil when accelerating
Burning engine oil during acceleration means that a large amount of blue smoke will be discharged from the exhaust pipe when the vehicle is running, such as stepping on the accelerator or standing on the accelerator. In serious cases, the blue smoke can be seen from the reflector on the side of the exhaust pipe after the accelerator is pressed sharply during driving. This is because the piston ring on the engine piston and the cylinder wall are not tightly sealed, and the engine oil directly jumps from the crankcase to 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 indicates that the engine has been seriously worn and needs to be overhauled, otherwise serious accidents will be caused.
Therefore, at the end of the article, I remind you once again that in case of failure of large parts, we should first be careful and not miss any small details, so as to fundamentally solve the problem.
