Cylinder liner for Renault Trucks DCI11

This cylinder liner, identified by part number 209WN28, serves as a component within the Renault Trucks DCI11 engine assembly. It is installed into the engine block to create a controlled environment for the piston movement. The liner manages the transfer of heat from the combustion process to the cooling system and protects the engine block structure from direct contact with the piston rings. The component is manufactured by Renault Trucks to meet the specific dimensional requirements of the DCI11 engine.

The cylinder liner is compatible with the Renault Trucks DCI11 engine. It is engineered to maintain the seal required for combustion pressure and to assist in regulating oil consumption within the cylinder assembly. Proper installation ensures that the piston maintains a consistent clearance, which is necessary for the mechanical operation of the engine.

Cylinder liners function as replaceable wear surfaces in internal combustion engines. By housing the piston, they allow for the containment of high-pressure gases and facilitate the thermal management of the combustion chamber. When the inner surface of the liner reaches its service limit, it is replaced to restore the compression and mechanical efficiency of the engine block.
