Cylinder liner for Renault Trucks AE390

The cylinder liner, part number 209WT07, acts as the internal sleeve for the combustion chamber in the Renault Trucks AE390 diesel engine. It is inserted directly into the engine block to provide a precise sliding surface for the piston and its rings. By maintaining the integrity of this surface, the component ensures consistent compression and effective lubrication during the engine cycle.

This component is compatible with the Renault Trucks AE390 engine. The actual manufacturer of this part is MAGRUMAPE. It is engineered to meet the specific dimensional requirements of the engine block to maintain proper clearance and sealing.

In heavy-duty diesel engines, cylinder liners facilitate the movement of the piston while containing the high-pressure gases generated during combustion. They are designed to be replaceable, allowing for the restoration of the cylinder bore surface without the need to replace the entire engine block. Proper installation and maintenance of the liner are necessary to prevent issues such as compression loss, excessive oil consumption, and power reduction.
