Cylinder liner for MAN

The cylinder liner, part number 227WT15, is a cylindrical component installed within the engine block of MAN machinery. It serves as the internal sleeve that provides a sliding surface for the piston, protecting the engine block from direct contact and wear during operation. This component is designed to withstand the internal pressures and temperatures generated during the combustion cycle while facilitating the transfer of heat from the piston and rings to the engine cooling system.

This liner is compatible with MAN engines used in various industrial crane and heavy machinery applications. Maintaining the integrity of the cylinder liner is necessary to ensure proper compression, which directly influences engine power, fuel efficiency, and emission levels. Proper fitment of this component helps prevent issues such as loss of compression or increased oil consumption that can occur when the cylinder wall surface is compromised.

In internal combustion engines, the cylinder liner acts as the primary contact surface for piston rings. It defines the combustion chamber volume and allows for the maintenance of a seal between the piston and the cylinder wall. By providing a consistent surface, it supports the reciprocating motion of the piston throughout the engine's operational cycles.
