Cylinder liner for Scania engines

The cylinder liner 037WN49 is a cylindrical component installed within the engine block of Scania diesel engines. It serves as the primary contact and sliding surface for the piston, defining the space where combustion occurs. By housing the piston and its rings, the liner protects the engine block from direct wear and manages the thermal and pressure loads generated during the engine cycle. Its surface finish is engineered to facilitate a proper seal with the piston rings, which is necessary for maintaining compression and managing oil consumption.

This component is designed for use in Scania diesel engines found in various trucks and heavy machinery applications. It provides the interface required for the piston assembly to operate within the cylinder bore. Proper installation of the liner ensures that the engine maintains its intended operating parameters for power and efficiency.

In internal combustion engines, cylinder liners serve to isolate the engine block from the combustion process. They allow for the replacement of the wear surface without requiring the replacement of the entire engine block. Liners are typically designed to dissipate heat from the combustion chamber to the cooling system, ensuring stable operating temperatures.
