Cylinder liner for Scania TD120

The cylinder liner, part number 478141, is a component for the Scania TD120 engine. It is installed into the engine block to provide a precise surface for the piston to travel against during operation. By acting as a barrier, the liner protects the engine block from the direct mechanical wear and thermal stress produced during the combustion cycle.

This component is compatible with the Scania TD120 engine model. It is designed to maintain the required internal dimensions for proper piston fitment and sealing within the engine assembly.

Cylinder liners function as the internal wall of the combustion chamber. They are engineered to manage heat transfer from the piston to the cooling system and to maintain the necessary oil film for lubrication. A properly fitted liner ensures that the engine maintains correct compression levels, which is necessary for efficient operation and power output.
