Cylinder liner for Renault Trucks M420

The cylinder liner 88034110 is a cylindrical component installed within the engine block of the Renault Trucks M420. It provides the necessary internal surface for the piston to travel during the combustion cycle. By housing the piston, the liner maintains the integrity of the combustion chamber and facilitates the movement of the piston rings.

This component is compatible with the Renault Trucks M420 engine, which is utilized in various heavy-duty vehicles and industrial machinery, including specific crane models. The liner is engineered to meet the dimensional and functional requirements of the engine block assembly, ensuring a proper fit for the piston and ring configuration.

In internal combustion engines, a cylinder liner acts as the primary contact surface for the piston and its rings. It is responsible for containing the pressure generated during combustion and managing heat transfer from the piston to the engine block cooling system. The inner surface is finished to support oil retention, which assists in lubrication and helps maintain the seal required for effective compression.
