Engine oil performance
The main performance of the engine burning oil is blue smoke. Idle engine wobble, engine oil in a routine maintenance (oil change cycle) (no leakage phenomenon) a serious lack of. If your car has been burning oil,
Two, engine oil generation reasons
The cause of engine oil is divided into two types:
1 is the appreciation of wear, that is, the number of vehicles in a certain number of kilometers after the normal phenomenon. The general vehicle is about two hundred thousand km, different vehicles, different people use different areas (air dust content) have a great impact on engine life. For more than a certain number of years of service and vehicle wear and tear I do not say, the overhaul of the overhaul.
2 abnormal wear: the cause of abnormal wear and tear caused by the product quality and improper use of early wear. If the phenomenon of burning oil on your car during the warranty period, please contact negotiation and manufacturers four S shop repair or replacement of the engine.
The cause of early wear of engine: the use of substandard oil, no overdue replacement of oil and oil filter, cold car throttle starting, long time operation, lack of oil under the condition of high temperature and long time running overload and high speed operation (engine speed per minute more than four thousand RPM), long in the air the quality (dust content exceed the standard), operation is not good and not due to replace the air filter under the condition of insufficient oil pump, oil pump, oil pressure force blockage and so on, will allow you to reduce the service life of the engine caused by early abrasion.
Know the reasons for their friends in the daily maintenance of the road to avoid the above error method, take good care of vehicles, to extend the life of the engine.
Three, which parts wear and tear will cause engine oil
1 Baotou beiben heavy truck parts wear of cylinder liner and piston will make the clearance of cylinder wall caused by the variable part of the oil fleeing into the combustion chamber.
2 Baotou beiben heavy truck parts of piston ring wear, piston ring and piston ring elastic weakened or broken away counterparts (several piston ring opening into a straight line) caused Mifengbuyan the oil into the combustion chamber.
3 valve oil seal aging damage will also allow part of the oil into the combustion chamber combustion, especially the intake valve oil seal aging damage more easily let the oil into the combustion chamber combustion.
4 engine exhaust pipe (oil chamber through the engine intake pipe) caused by the oil chamber pressure is too high to cause some of the oil into the combustion chamber combustion.
5 Baotou beiben heavy truck parts oil cylinder pad and the cylinder can also make some hedge oil into the combustion chamber.
Four, how to determine where the fault
Check from simple to complex, from easy to difficult.
1 check the exhaust pipe is not smooth. If not, clean or replace. After running a period of time when the view is the lack of oil, the exhaust pipe is also blue smoke.
2 measuring cylinder pressure, cylinder pressure is normal: it should be due to the aging of the valve seal damage caused by burning oil, replace the valve seal. Replacement of all oil seal.
3 if the cylinder pressure cylinder, cylinder or lower than the normal value, then only the cylinder head check cylinder pad is washed off the oil road, bore wear and wear degree of piston and piston ring spring. If it is just the oil way, replace the cylinder pad on the line. If the cylinder bore and piston wear too large, suggest replacing all the cylinder (cylinder), piston, piston ring. If the bore wear small, replaceable piston and piston ring. If it is the reason of the piston ring, as long as the replacement of all piston rings can be.
