ABSTRACT:
An engine is cooled using high pressure water injected into the piston with the water converted to high pressure steam by the heat from combustion with heat transfer taking place in passages in the piston and in and between grooves in the piston and the cylinder sleeve. The high pressure steam is conducted between the piston and cylinder walls to lubricate, so there will be no need for piston rings, with a part of it passing into the crankcase, and a part of it going into the combustion chamber where it contributes to power production. The piston skirt has a spring-loaded washer access to a void in a lower passage for balancing pressures.
