Diesel generator piston in the process of using burning is one of the common faults, caused the burning loss of the piston of diesel generator:
1 injector drop of oil or diesel generator diesel oil atomization, long time to the top of the piston piston top combustion, caused by high temperature, so that the piston is burning.
2 diesel generator piston oil channeling serious wear and tear or rupture, causing the piston burning.
3 choice of inferior oil, accelerate the diesel engine cylinder wear, crankcase exhaust pressure, the combustion chamber carbon increased, resulting in loss of piston.
4 diesel engine cylinder oil and oil time is not uniform, so that part of the cylinder combustion deterioration, formation of coke burning diesel piston cylinder part of the top temperature is too high, resulting in diesel engine thermal fatigue and burning, causing the piston burning.
There are 5 problems piston cylinder quality, if the piston diesel engine in the casting pores, porosity, cracks, slag and other defects, under the high temperature, these defects will become the source of fatigue and cause fatigue damage of piston; piston in the slag melting first, making plug fuse.
6 piston top clearance improper assembly diesel engine, if the piston top clearance to adjust properly, will affect the compression ratio of the diesel engine cylinder or piston, resulting in burning, which requires the diesel engine in the assembly should be strictly in accordance with the requirements of regulation.
