Yanmar M220 Cylinder Liner
Mega Marine supplies genuine and reconditioned cylinder liner for Yanmar M220 marine engines, along with complete engines and a comprehensive range of spare parts. Fast RFQ response and global delivery.
The cylinder liner forms the precision-finished cylindrical bore in which the piston and rings reciprocate. Marine engine liners are cast from special alloyed iron grades providing the optimal combination of hardness, thermal conductivity, and tribological properties. The bore surface has a controlled cross-hatch honing pattern that retains the cylinder oil film critical to ring and liner longevity.
Function in the Engine
Forms the combustion chamber wall, guides the piston and piston rings with precise diametral clearance, transfers combustion heat to the cooling water jacket, retains the cylinder lubrication oil film on the honed surface.
