Cylinder liner for Scania D12B

The cylinder liner, part number 037WN32, serves as the internal sleeve for the Scania D12B diesel engine. It is installed within the engine block to create the cylinder wall where the piston moves during operation. This component maintains the necessary seal with the piston rings to manage compression and prevent the bypass of combustion gases or lubricating oil into the crankcase. Proper installation ensures the internal geometry remains consistent for the reciprocating motion of the piston assembly.

This component is specifically engineered for the Scania D12B engine model. It provides the required sliding surface for the piston to facilitate the combustion cycle. Cylinder liners function as the primary interface for the piston and rings, managing the heat transfer from the combustion chamber to the engine cooling system while maintaining the structural integrity of the cylinder bore. By providing a controlled surface, the liner supports the maintenance of engine compression and helps regulate oil consumption within the cylinder assembly.
