Cylinder liner for Mercedes-Benz OM355

The cylinder liner, part number 89089110, serves as the internal sleeve for the combustion chamber in the Mercedes-Benz OM355 engine. It acts as the primary contact surface for the piston and piston rings, protecting the engine block from direct wear during operation. By maintaining the integrity of the cylinder wall, this component ensures proper compression levels are sustained within the combustion chamber throughout the engine cycle.

This component is specifically engineered for use with the Mercedes-Benz OM355 engine, which is commonly found in heavy-duty industrial cranes, trucks, and construction machinery. It is designed to meet the original dimensional and tolerance specifications required for this engine series. The liner facilitates heat transfer from the combustion process to the engine cooling system, helping to regulate internal operating temperatures.

In internal combustion engines, cylinder liners are used to define the cylinder bore and provide a controlled surface for piston movement. They are critical for maintaining the seal between the piston rings and the engine block, which prevents gas leakage and maintains the necessary pressure for efficient engine output.
