Cylinder liner for Mercedes-Benz OM636

The cylinder liner 88526190 functions as the internal sleeve for the Mercedes-Benz OM636 engine block. It provides the necessary surface for the piston and its rings to move during the combustion cycle. By maintaining a precise internal diameter, the liner ensures that the piston maintains the required seal within the cylinder to preserve compression. It also acts as a thermal conduit, transferring heat from the piston assembly to the engine block cooling system.

This component is specifically engineered for the Mercedes-Benz OM636 diesel engine. It is installed within the engine block to define the cylinder bore. Proper installation of this liner is required to maintain the tolerances necessary for the piston movement and to prevent blow-by or oil consumption issues that occur when cylinder surfaces are compromised.

Cylinder liners are used in internal combustion engines to create a replaceable wear surface for the piston. They allow for the restoration of the cylinder bore to factory specifications during engine overhauls without requiring the replacement of the entire engine block. The liner must maintain its shape under the pressure and thermal loads generated during engine operation.
