Cylinder liner for Scania

The cylinder liner, identified by part number 422840, functions as the internal sleeve within the engine block. It provides the surface along which the piston slides during the combustion cycle. This component is engineered to maintain the necessary compression within the cylinder and facilitates the transfer of heat away from the combustion chamber to the engine cooling system.

This component is compatible with various Scania engine configurations. It is designed to meet the specific dimensional requirements for proper fitment within the engine block, ensuring correct alignment for the piston rings and effective oil control. Proper installation of the liner is a standard procedure during engine overhauls to restore operating efficiency.

Cylinder liners act as the primary interface for the piston and rings, creating the sealed environment required for power generation in internal combustion engines. By providing a replaceable surface, these liners allow for the restoration of cylinder geometry without requiring the replacement of the entire engine block.
