Cylinder liner for Mercedes-Benz 240D

The cylinder liner, part number A6160110310, serves as the internal wall of the combustion chamber within the Mercedes-Benz 240D engine. It is inserted into the engine block to provide a precise surface for the piston rings to seal against as the piston moves through its stroke. By housing the combustion process, the liner manages the thermal and mechanical loads generated during engine operation.

This component is engineered specifically for the Mercedes-Benz 240D engine block. It facilitates the transfer of heat from the combustion chamber to the cooling system and maintains the cylinder geometry required for consistent compression. Proper installation of the liner is a standard procedure during engine overhaul to restore the internal dimensions of the cylinder bore.

In internal combustion engines, cylinder liners act as a replaceable wear surface. They protect the main engine block from direct contact with the piston and rings, allowing for maintenance of the cylinder bore without requiring the replacement of the entire engine block. This design ensures that the engine maintains its intended compression ratios and operational efficiency over its service life.
