Cylinder liner for Scania TD40A

The cylinder liner, part number 1542136, functions as the internal sleeve for the engine block in the Scania TD40A engine. It provides the contact surface for the piston assembly during the combustion cycle. By housing the piston, the liner facilitates the transfer of heat from the combustion chamber to the engine cooling system while maintaining the necessary seal for the piston rings to ensure proper compression and oil control.

This component is compatible with the Scania TD40A engine model. It is designed to fit precisely into the engine block to maintain the required internal diameter for the reciprocating motion of the piston. Proper installation of this liner is necessary to restore the compression and operational efficiency of the engine block assembly.

Cylinder liners are used in internal combustion engines to create a replaceable wear surface within the block. They allow for the restoration of the cylinder bore without replacing the entire engine block. The internal surface finish of the liner is engineered to interact with the piston rings, which is essential for maintaining engine power and minimizing oil consumption during operation.
