Cylinder liner for Scania TD122

The cylinder liner is a critical component within the engine block of the Scania TD122. It forms the internal wall of the cylinder, creating the necessary housing for the piston to move through its compression and power strokes. By maintaining a precise internal diameter, the liner ensures that the piston rings can effectively seal the combustion chamber, which is necessary for maintaining compression and preventing the leakage of gases and oil during engine operation.

This part is compatible with the Scania TD122 engine model. The actual manufacturer for this component is Scania. The liner is engineered to meet the specific dimensional requirements of the engine block, facilitating heat transfer from the combustion process to the cooling system and providing a consistent surface for the reciprocating motion of the piston assembly.

Cylinder liners serve as the primary interface between the piston rings and the engine block. Their function is to withstand the thermal and mechanical stresses of the combustion cycle while minimizing friction. A properly fitted liner maintains the geometric stability of the cylinder bore, which supports efficient fuel combustion and consistent power output throughout the service life of the engine.
