MAN B&W K80MC Cylinder Liner

MAN B&W K80MC Cylinder Liner is a critical cylinder-unit component for MAN B&W K80MC-series low-speed two-stroke marine diesel engines. The cylinder liner forms the running surface for the piston and piston rings and operates under high mechanical, thermal and lubrication loads. Correct liner condition is therefore important during engine maintenance and overhaul operations.

The K80MC engine family includes large-bore low-speed marine engines used for commercial vessel propulsion. The K80MC-C configuration has an 800 mm cylinder bore and 2,300 mm piston stroke, with engine configurations available from 6 through 12 cylinders.

For the K80MC-C cylinder unit, the published MAN B&W maintenance documentation identifies the cylinder liner as part of the “Cylinder Liner and Cylinder Lubrication” section. The liner is installed together with a cooling jacket and incorporates components associated with cylinder lubrication and piston cleaning.
