D905 Diesel Engine Cylinder Liner 16224-02310 For KUBOTA

Reasons for cylinder pulling

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.

Cylinder liners are divided into two categories: dry cylinder liners and wet cylinder liners. The cylinder liner that does not come into contact with cooling water on the back is called a dry cylinder liner, while the cylinder liner that comes into contact with cooling water on the back is a wet cylinder liner. The dry cylinder liner has a thin thickness, simple structure, and convenient processing. The wet cylinder liner is directly in contact with cooling water, which is beneficial for engine cooling and lightweight.
