Cylinder liner for Renault Trucks AE390

The cylinder liner 509GC463 serves as a replaceable component within the engine block of the Renault Trucks AE390. It provides a dedicated sliding surface for the piston and piston rings, protecting the engine block from direct wear caused by reciprocating motion and combustion temperatures. This component also facilitates the transfer of heat from the cylinder to the engine cooling system.

This part is compatible with the Renault Trucks AE390 engine. It is engineered to maintain the structural integrity of the cylinder bore, ensuring proper alignment and sealing for the piston assembly. By providing a precise surface for the piston rings, it assists in maintaining engine compression and managing oil consumption during operation.

Cylinder liners are used in internal combustion engines to create a renewable wear surface. They allow for the restoration of cylinder dimensions without the need to replace the entire engine block. By managing thermal transfer and friction, the liner supports the overall efficiency of the engine system.
