Fault phenomenon: while driving the exhaust pipe of the engine exhaust smoke or dust and smoke, smell the burnt smell.
Fault: Baotou beiben exhaust pipe exhaust smoke or soot parts when the engine is running, is the main oil into the cylinder combustion chamber caused by combustion. Remove the spark plug can be found serious carbon deposition, high oil consumption, mostly oil into the combustion chamber. When the engine oil enters the cylinder to be heated and evaporated, the blue oil and gas can be discharged together with the exhaust gas.
The main reason for the oil into the cylinder:
1, cylinder wear or piston ring seal is bad, cause crankcase oil into the combustion chamber.
2, Baotou North Heavy Duty Truck oil sump oil level is too high or too high oil pressure, so that the cylinder wall adhesion of oil too much.
3, valve and valve guide wear make it with the clearance is too large, the oil is sucked into the combustion chamber.
4, Baotou North heavy truck parts air filter oil level is too high or the filter is seriously blocked, so that the oil is sucked into the combustion chamber.
Troubleshooting:
1, if the engine is used for a long time or has reached the overhaul interval mileage requirements, the power of the engine, the main reason is the piston and the piston ring wear serious, poor sealing and channeling oil, should be sent to the garage for repair.
2, if the engine power performance is good, you should first check if the oil pressure, oil pressure is too high should be adjusted; check the dipstick at oil level is too high, if the oil level is too high, should be released excess oil; check the air filter is clogged, if it is to plug the filter should be cleaned or replaced; check the air filter if the oil level is too high, too high level of oil should be released excess oil.
