Cylinder liner for Scania

The cylinder liner provides a controlled and replaceable surface for the piston to travel within the engine block. It protects the block from direct wear caused by the movement of the piston and rings while containing the combustion process. The inner surface features a honed finish to retain lubricating oil, which helps minimize friction between the piston rings and the cylinder wall. By maintaining this interface, the component supports efficient compression and helps regulate oil consumption during operation.

This component is compatible with various Scania diesel engines used in heavy machinery and transport equipment. The part number 422090P06 is engineered to meet the specific dimensional and tolerance requirements for these power units. Proper installation of this liner is necessary to restore engine efficiency and prevent power loss or excessive blow-by caused by worn or damaged cylinder surfaces.

Cylinder liners serve as the primary wear surface in internal combustion engines. They are designed to be replaced when the internal diameter exceeds service limits or when the surface finish is compromised, allowing for the restoration of the engine block without requiring a full engine replacement.
