Abstract
A cylinder liner is disclosed for an internal combustion engine including a cylindrical hollow body having a press fitted upper end and a stop located intermediate the liner ends for engaging an engine block liner stop to provide upper and lower seals for a coolant passage. The outside surfaces of the liner adjacent the press fitted upper end and the stop are formed to permit a settable plastic material to be used between the liner and engine block to assist in forming the coolant seal and to provide radial support to the liner to permit the lower 30 percent of the cylinder liner to be free of any direct contact with the engine block. This design also permits use of a smaller capacity cooling system and improves lubricating oil flow within the engine block.
