Cylinder liner for Mercedes-Benz

The cylinder liner, part number 89556110, acts as the internal sleeve for the cylinder bore within Mercedes-Benz engines. It provides a precise sliding surface for the piston rings to travel against during the combustion cycle. This component also facilitates the transfer of thermal energy from the combustion chamber to the engine cooling system, helping to maintain stable operating temperatures under load. Proper installation of this liner is necessary to ensure the piston rings maintain a seal against the cylinder wall, which is required to preserve engine compression and combustion efficiency.

This component is engineered for specific Mercedes-Benz engine configurations. It is manufactured to meet the dimensional requirements of the engine block to ensure a correct fit during engine overhauls or rebuilds. The surface finish of the liner is designed to support oil film retention, which assists in the lubrication of the piston and ring assembly during operation.

Cylinder liners are used in internal combustion engines to define the cylinder bore and protect the engine block from the direct heat and friction of the piston movement. By providing a replaceable surface, they allow for the restoration of the cylinder geometry without needing to replace the entire engine block.
