Cylinder liner for Mercedes-Benz OM611

The cylinder liner, part number 14-020300-00, acts as the internal sleeve for the Mercedes-Benz OM611 diesel engine. It forms the sliding surface for the piston and defines the combustion chamber where power generation occurs. By providing a precise path for the piston, this component facilitates the transfer of heat from the combustion process to the engine cooling system while maintaining the necessary seal for compression.

This component is specifically engineered for the Mercedes-Benz OM611 engine platform. The dimensions and surface finish are configured to interact with the piston rings to manage oil consumption and maintain internal pressure. Proper installation of this liner is necessary to ensure the engine operates within its intended parameters.

Cylinder liners serve as the primary interface for reciprocating motion within an internal combustion engine. They are installed into the engine block to provide a replaceable surface for the piston, allowing for the restoration of cylinder geometry and compression efficiency during engine maintenance or overhaul procedures.
