Cylinder liner for Scania TD120

The cylinder liner 468830 functions as the internal sleeve for the combustion chamber in the Scania TD120 engine. It provides a defined surface for the piston to travel during the compression and power strokes, effectively separating the piston assembly from the engine block casting. This component manages the heat transfer from the combustion process to the cooling system and maintains the seal required for proper engine compression.

This part is compatible with the Scania TD120 engine found in various heavy-duty trucks, buses, and industrial machinery applications. It is designed to meet the specific dimensional requirements of the TD120 cylinder bore. Proper installation of this liner is necessary to ensure the piston rings maintain an effective seal against the cylinder wall, which prevents blow-by and maintains oil control within the crankcase.

Cylinder liners are used in internal combustion engines to provide a replaceable wear surface for the piston. By utilizing a liner, the engine block remains protected from direct contact with the piston rings, allowing for easier engine overhauls when the internal surfaces eventually reach their service limits.
