Cylinder liner for MAN

The cylinder liner, part number 89470190, serves as the internal sleeve within the engine block that provides the sliding surface for the piston. It is a critical component of the engine assembly, facilitating the reciprocating motion of the piston during the combustion cycle. By maintaining a precise internal diameter, the liner ensures an effective seal with the piston rings, which is necessary for achieving optimal compression and managing oil consumption. Furthermore, the liner acts as a thermal bridge, conducting heat away from the combustion chamber and into the engine cooling system to maintain stable operating temperatures.

This component is manufactured by MAGRUMAPE for use in MAN engines found in heavy machinery and cranes. It is engineered to meet specific dimensional tolerances required for the engine block interface. Cylinder liners are typically installed in internal combustion engines to form the cylinder wall, protecting the engine block from the friction of the piston rings and the heat of combustion. Proper installation ensures that the piston moves smoothly while containing the high-pressure gases generated during the power stroke, which is essential for the overall efficiency and output of the engine.
