Cylinder liner for Renault Trucks

The cylinder liner is a sleeve installed within the engine block of internal combustion engines used in heavy-duty trucks and machinery. It serves as the internal wall of the cylinder, providing a sliding surface for the piston. By acting as a replaceable interface, the liner allows for engine block maintenance and restoration without requiring the replacement of the entire engine housing. The component facilitates the transfer of thermal energy from the combustion chamber and the piston assembly to the engine cooling system.

This part is identified by part number 89420110 and is engineered for specific Renault Trucks engine configurations. The internal diameter is machined to maintain a seal with the piston rings, which supports engine compression and regulates oil consumption. Proper installation of the liner ensures that the piston maintains its intended path during the combustion cycle, contributing to the operational parameters of the engine assembly.
