4D130 Diesel Engine Cylinder Liner 6115-21-2210 6115-21-2211 For KOMATSU

Abnormal operation of piston ring:

The opening clearance is too small, causing the piston ring to break; The clearance between heaven and earth is too small, which makes the piston ring stuck; Too much carbon deposits cause the piston ring to stick to the ring groove and lose elasticity, resulting in fracture or gas leakage; The opening clearance is too large or the wear is serious, resulting in gas leakage. The gas leakage damages the lubricating oil film, resulting in high surface temperature. After the piston ring is broken, the debris is easy to fall into the piston cylinder, causing cylinder pulling and cylinder biting.

Using inferior fuel:

Incomplete combustion brings more combustion residues; Severe post combustion phenomenon, causing an increase in exhaust temperature and failure to take timely technical measures; The alkaline value of cylinder lubrication is not appropriate. In addition, some diesel engines may experience prolonged overload operation, increased thermal load, overheating, expansion, or poor alignment of moving components, resulting in cylinder pulling.
