Cylinder liner for Mercedes-Benz 220D

The cylinder liner, part number A6150111110, is a cylindrical component designed for insertion into the engine block of the Mercedes-Benz 220D. It serves as the primary contact surface for the piston and its rings, protecting the engine block from direct friction and thermal stress during operation. By providing a controlled environment for the reciprocating motion of the piston, this component facilitates the maintenance of proper compression levels within the combustion chamber.

This component is engineered specifically for the Mercedes-Benz 220D engine assembly. Proper installation ensures a precise fit between the liner, the piston, and the rings, which is necessary for effective lubrication management and the prevention of excessive oil consumption. Replacing worn liners is a standard procedure during engine overhauls to restore internal clearances and operational efficiency.

In internal combustion engines, cylinder liners function as the wear-resistant barrier between the moving piston assembly and the engine block. They allow for the restoration of cylinder geometry without requiring the replacement of the entire engine block, serving as a critical element in the long-term maintenance of heavy-duty and commercial power units.
