Cylinder liner for Scania

The cylinder liner, part number 89439110, acts as the internal sleeve within the engine block of Scania machinery. It provides the necessary sliding surface for the piston and its rings during operation. By lining the cylinder bore, this component protects the engine block from direct contact with the piston and manages the thermal loads generated during the combustion cycle. It is engineered to maintain proper compression levels within the combustion chamber, which supports consistent engine power output and efficient operation.

This component is compatible with Scania engines used in heavy equipment and industrial cranes. It is manufactured by Scania to meet the specific dimensional and surface finish requirements of their engine blocks. Proper installation of this liner is necessary to ensure the integrity of the cylinder assembly and to maintain the specified tolerances between the piston and the cylinder wall.

In internal combustion engines, cylinder liners facilitate heat transfer from the piston to the cooling system and provide a controlled environment for reciprocating motion. They are typically installed as wet or dry sleeves depending on the engine design, allowing for the restoration of the cylinder bore surface without replacing the entire engine block.
