Cylinder liner for Scania TD120

The cylinder liner, also known as a sleeve, serves as the internal wall of the cylinder block where the piston travels during engine operation. It guides the reciprocating motion of the piston while containing the pressure generated by the combustion process. This component is designed to facilitate heat transfer from the piston assembly to the engine cooling system, maintaining thermal stability within the cylinder bore.

This specific liner is compatible with the Scania TD120 engine. The inner surface is finished to support proper oil retention, which assists in the lubrication of the piston rings and reduces friction during the stroke. By maintaining the integrity of the cylinder bore, this part ensures proper compression and prevents blow-by gases from entering the crankcase.

Cylinder liners are used in internal combustion engines to provide a replaceable wear surface for the piston and rings. They allow for the restoration of the cylinder bore to original specifications without requiring the replacement of the entire engine block. Proper installation is required to ensure a correct seal between the liner and the engine block cooling passages.
