Cylinder liner for Scania

The cylinder liner 422093 serves as the internal sleeve for the engine block, creating the sliding surface for the piston as it moves within the cylinder. This component is designed to maintain the integrity of the combustion chamber by housing the piston and its rings, ensuring that the engine maintains proper compression during operation. It acts as a barrier between the piston assembly and the cooling system, facilitating heat transfer away from the combustion area.

This part is specifically engineered for Scania engines used in heavy-duty applications. It is manufactured to meet the precise dimensional requirements of the engine block to ensure a correct fit and alignment. The inner surface is machined to allow the piston rings to create a seal, which is necessary for managing oil consumption and maintaining internal pressure. Cylinder liners are a standard component in internal combustion engines, where they provide a renewable surface that can be replaced if the cylinder wall experiences wear over time, thereby extending the service life of the engine block itself.
