Cylinder liner for Renault Trucks MID/M IP 620

The cylinder liner with part number 89077110 is a component for Renault Trucks MID/M IP 620 engines used in heavy-duty transport and industrial machinery. This cylindrical part fits into the engine block to provide a precision sliding surface for the piston assembly. It serves as a protective barrier for the engine block against the mechanical movement of the piston and piston rings, while also managing the thermal and pressure conditions within the combustion chamber. Maintaining the integrity of this liner is necessary for effective cylinder compression, which influences engine power output and fuel efficiency.

This component is compatible with the Renault Trucks MID/M IP 620 series. It facilitates heat transfer from the piston and rings to the engine cooling system, helping to regulate internal temperatures during operation. A properly functioning liner prevents issues such as compression loss and excessive oil consumption that can arise from surface wear or damage. By providing a stable cylinder wall, this part supports the overall mechanical operation of the engine block assembly.
