ABSTRACT:
A method and apparatus for better sealing a piston to its cylinder, to effectively eliminate efficiency loss due to leakage of the high-temperature, high pressure driving gas around the edges of the piston. An elastomeric seal is located so as to seal the piston and cylinder combination at a minimum sufficient distance from the combustion chamber to prevent heat damage to the seal material by conduction of heat through the piston or cylinder material.
