Cylinder liner for Mercedes-Benz OM355

The cylinder liner, identified by part number 88869190, serves as the internal sleeve within the engine block for the Mercedes-Benz OM355. It provides a precise surface for the piston to travel during the combustion cycle. By housing the piston, this component protects the engine block from direct contact and manages the thermal and mechanical stresses generated during operation.

This part is compatible with the Mercedes-Benz OM355 engine. It is engineered to meet the specific dimensional and functional requirements of this engine series to ensure proper fitment and operation within the cylinder assembly.

Cylinder liners function as the primary wear surface in an internal combustion engine. They contain the pressure and heat of the combustion process while providing a controlled environment for the piston rings to seal, which maintains compression and prevents oil consumption. Proper installation of the liner is necessary to ensure the integrity of the cylinder bore and the overall efficiency of the engine block.
