Abstract
A replaceable cylinder liner for an internal combustion engine. The position of the liner within the block is established by a midstop. An interference fit below the midstop seals the bottom end of a cooling passage that extends around the liner. The top end of the cooling passage is sealed by an o-ring, and when the engine is warmed up by an interference fit also. The top of the cooling passage is close to the top dead center position of the top piston ring, and reduces the temperature of the top piston ring.
