Engine oil is a common phenomenon in automobile engines, so what about engine oil? Is it difficult to solve the engine oil? Why does the engine burn the oil? Here we are to see the cause of the engine oil. In general, there are two ways to burn oil in an automobile engine. There are different solutions. First, the performance of engine oil burning; engine oil burning is the main performance of the exhaust pipe blue smoke. The engine will tremble at idle speed, and engine oil is seriously lacking in a routine maintenance cycle. So your car has been running oil. Two, the cause of engine oil production caused by engine oil burning is divided into two kinds: 1. is to reward the wear, that is, the vehicle in a certain number of kilometers after the normal phenomenon. The average vehicle is about two hundred thousand kilometers. Different cars, different people and different areas have great influence on the service life of the engine. I will not say more about the normal wear of vehicles exceeding a certain useful life and kilometers. 2. abnormal wear: the cause of abnormal wear is product quality and early wear caused by improper use. If your car is burning oil during warranty period, please contact with the manufacturer's four S shop in time to repair or replace the engine. The causes of early engine wear are as follows: the use of unqualified oil, overdue oil and oil and oil filter, cold car big throttle starting, long time lack of engine oil operation, long time high temperature state operation, long-term overloading and high speed operation, long time in poor air quality and expiration of air cleaner Condition running, low oil pump power, low oil pressure, blockage of oil passages and so on will reduce the service life of your engine and cause early wear. Know the reason, friends in daily maintenance, we should avoid the above error method, love good vehicle, extend the service life of the engine. Three, which parts wear aging will cause engine oil 1. cylinder sleeve, piston wear and tear will make the cylinder wall gap larger and cause part of the oil into the combustion chamber. 2. wear and tear of piston ring, weakening or breaking of piston ring elasticity, and piston ring running opposite, resulting in tight sealing and some oil running into combustion chamber. The aging and damage of the 3. valve seals will also cause some oil to burn into the combustion chamber, especially the aging and breakage of the intake valve oil seal, which makes it easier for the oil to burn into the combustion chamber. 4. the blockage of the engine exhaust pipe caused the excessive oil chamber pressure to cause some oil to burn into the combustion chamber. 5. oil cylinder and cylinder block will also cause some oil to burn into the combustion chamber. Four, how to judge the location of the fault from simple to complex, easy to difficult. 1. check the exhaust pipe is not smooth. If it is not accessible, clean or replace. Drive for a while to see if the oil is missing and whether the exhaust pipe is still emitting blue smoke. 2. measure cylinder pressure, cylinder pressure is normal: that should be due to valve oil seal aging damage caused by burning oil, replace valve oil seal. It is suggested that all oil seal should be replaced. 3. if the cylinder pressure single cylinder, multi cylinder or both are lower than the normal value, then only the cylinder cover check whether the cylinder pad flush the oil channel, the wear degree of cylinder diameter, the degree of piston wear and tear, the elasticity of the piston ring and so on. If only the oil channel is washed, the cylinder pad will be replaced. If cylinder bore and piston wear too much, it is recommended to replace all cylinders, pistons and piston rings. If the bore diameter is not worn, piston and piston rings can be replaced. If the piston ring is the reason, just replace all piston rings.
