Cylinder liner for MAN engines

The cylinder liner 227WT39 is a cylindrical component designed for installation into the engine block of MAN machinery. It acts as the primary contact surface for the piston, shielding the engine block from the friction and thermal stresses generated during the combustion cycle. By providing a precise surface for the piston rings, this component facilitates effective sealing and helps maintain the compression levels necessary for engine operation.

This part is compatible with various MAN engine configurations. It is manufactured by MAN to meet specific dimensional and thermal requirements for their engine series. As a replaceable component, the liner allows for the restoration of the cylinder bore surface without requiring the replacement of the entire engine block.

In internal combustion engines, cylinder liners provide a controlled environment for the reciprocating motion of the piston. They are engineered to manage heat transfer from the combustion chamber to the cooling system while maintaining structural integrity under the high pressures of the power stroke.
