Cylinder liner for Scania TD63

The cylinder liner, part number 14-450130-00, acts as the internal wall of the combustion chamber in the Scania TD63 engine. It provides a smooth, cylindrical surface for the piston rings to seal against, which maintains compression and prevents combustion gases from escaping into the crankcase. By housing the piston assembly, this component protects the main engine block from direct friction and heat exposure during the combustion cycle.

This part is compatible with the Scania TD63 engine model. It is manufactured to meet the specific dimensional requirements of this engine series to ensure a proper fit within the block and alignment with the piston stroke. Proper installation of the liner is necessary to maintain the thermal transfer path from the cylinder to the engine cooling system.

In internal combustion engines, cylinder liners serve as a replaceable surface that manages the wear caused by the reciprocating motion of the piston. They are engineered to facilitate heat dissipation from the combustion chamber to the water jacket, helping to regulate the operating temperature of the engine block.
