Cylinder liner for MAN

The cylinder liner 89339110 is a cylindrical sleeve inserted into the engine block to provide a precise sliding surface for the piston and its rings. By acting as a barrier between the moving piston assembly and the engine block, this component manages the friction and thermal stress generated during the combustion cycle. It is engineered to facilitate heat transfer from the combustion chamber to the engine cooling system, maintaining internal temperatures within operational limits.

This component is compatible with various MAN diesel engines utilized in industrial and heavy machinery applications. The liner allows for the maintenance of the cylinder bore without requiring a full replacement of the engine block, supporting efficient engine overhauls. It ensures proper sealing for the piston rings, which is necessary to maintain compression and prevent oil consumption issues during operation.

In internal combustion engines, cylinder liners are used to define the cylinder wall and protect the block from mechanical wear. They are typically installed as a replaceable sleeve, allowing technicians to restore the original bore dimensions and surface finish of the engine cylinders during a rebuild process.
