Main reasons for engine oil burning and maintenance methods

Car Maintenance and maintenance of engine oil in May 12th, is the problem we will meet during the ordinary driving process. Today, we will explain the cause of engine oil and the measures to deal with it.

1. Performance of engine oil

the main performance of engine oil is exhaust blue smoke. The engine will tremble at idle speed, and the engine oil is seriously lacking in a regular maintenance cycle. So your car has been running oil.

Two, the cause of engine oil production

there are two reasons for engine oil burning:

1. is enjoying normal wear, which is a normal phenomenon after a certain kilometer driving. The general vehicle is about two hundred thousand kilometers. Different vehicles, different people use and different areas (air dust content) have a great impact 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.

abnormal wear of.2.: the causes of abnormal wear are early wear and tear caused by improper product quality and 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 cause of engine early wear is the use of unqualified oil, overdue oil and oil and oil filter, cold car big throttle start, long time lack of engine oil operation, long time high temperature state operation, long overload and high speed operation (the engine speed is more than four thousand rotates per minute), long time in the air Gas quality (dust content excess) is not good and the expiration of air cleaner condition operation, oil pump oil pump power, low oil pressure, oil channel blockage and so on, will allow your engine to reduce life cause early wear.

knowing the reason, friends should avoid the above mistakes in daily maintenance and take good care of the vehicle and prolong the service life of the engine.

three. Wear and tear of parts will cause engine burn oil.

the wear of.1. cylinder liner and piston will cause the clearance of the cylinder wall to increase and some oil will burn into the combustion chamber.

the wear of the.2. piston ring, the elastic weakening or broken of the piston ring, and the piston ring walk on the mouth (a line of several piston rings) cause the seal to be tight and part of the oil is channeling into the combustion chamber.

the ageing and breakage of the.3. valve oil seal will also allow some oil to enter the combustion chamber, especially when the oil seal of the intake valve is damaged more easily to let the oil enter the combustion chamber.

the blockage of.4. engine exhaust pipe (engine room intake pipe) causes excessive oil chamber pressure to cause some oil to burn into the combustion chamber.

the oil cylinder of the.5. cylinder liner and the cylinder will also cause some oil to burn into the combustion chamber.

Four. How to judge the fault

Check from simple to complex, from easy to difficult.

1. inspection of 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 all 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 (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.
