Cylinder liner for Renault Trucks

The cylinder liner, part number 89078110, serves as a replaceable sleeve within the engine block of Renault Trucks machinery. It provides a controlled surface for the piston to travel against, separating the piston rings from the engine block material and managing the thermal transfer from the combustion chamber to the cooling system. This component is essential for maintaining the integrity of the cylinder bore and ensuring the piston maintains a proper seal during the compression and power strokes of the engine cycle.

This component is compatible with various Renault Trucks engine configurations. It is manufactured to precise dimensions to ensure a correct interference or slip fit within the engine block, depending on the specific engine design. Proper installation of this liner is necessary to maintain the required cylinder diameter and surface finish for effective oil film retention and ring sealing.

Cylinder liners are used in internal combustion engines to form the cylinder wall. They allow for the restoration of the engine block to its original specifications during a rebuild by replacing the worn surface rather than machining the block itself. By providing a consistent bore surface, the liner helps preserve compression and prevents blow-by, which is necessary for the engine to operate at its intended power output.
