Cylinder liner for Scania TD122

The cylinder liner, part number 037WN51, serves as the internal sleeve for the Scania TD122 engine block. It provides the precise sliding surface for the piston assembly, facilitating the reciprocating motion required for engine operation. By containing the combustion process, this component maintains the necessary seal for compression and manages heat transfer from the combustion chamber to the engine cooling system.

This component is compatible with the Scania TD122 engine series. It is designed to fit directly into the engine block, allowing for the restoration of cylinder wall geometry without requiring a complete block replacement. Proper installation ensures that the piston rings maintain an effective seal against the liner wall, which is necessary for maintaining engine compression and preventing oil bypass during operation.

Cylinder liners function as replaceable wear surfaces in internal combustion engines. They are engineered to withstand the thermal and mechanical stresses generated during the power stroke. By providing a renewable interface for the piston, these liners allow for engine overhauls and maintenance procedures that extend the operational life of the engine block.
