Cylinder liner for Mercedes-Benz engines

The cylinder liner 89342190 functions as the internal sleeve for the engine block in Mercedes-Benz power units. It provides a precise sliding surface for the piston rings, enabling the reciprocating motion required to generate power. By housing the piston, this component defines the combustion chamber and ensures that the pressure generated during the combustion cycle is contained effectively within the cylinder.

This part is designed for specific Mercedes-Benz engine configurations found in industrial cranes, heavy trucks, and various types of heavy machinery. The internal surface is machined to specific tolerances to facilitate proper ring sealing and heat transfer from the piston to the engine cooling system. Maintaining the integrity of the cylinder liner is necessary for consistent compression and efficient oil control within the engine assembly.

Cylinder liners are used in internal combustion engines to protect the engine block from direct wear caused by piston movement. They allow for the replacement of the sliding surface without needing to replace the entire engine block. Proper installation and alignment are required to ensure the liner maintains its position and heat dissipation capabilities during operation.
