Cylinder liner for Renault Trucks AE390

The cylinder liner, part number 14-020510-00, is a precision component installed within the engine block of Renault Trucks AE390 machinery. It creates the internal cylindrical surface that guides the piston movement throughout the combustion cycle. By providing this interface, the liner protects the engine block from direct contact with the piston and rings, while facilitating the transfer of heat away from the combustion chamber to the cooling system. This component is manufactured by Renault Trucks.

Proper installation of this liner ensures a consistent seal with the piston rings, which is necessary to maintain compression and control oil consumption within the cylinder. As the piston reciprocates, the liner surface manages the friction and thermal loads generated during engine operation. In heavy machinery and transport applications, maintaining the integrity of the cylinder bore is key to engine efficiency and power output.
