METHOD TO UP ENGINE EFFICIENCY BY COMPLEX THERMAL CYCLE, ROTARY PISTON ENGINE TO IMPLEMENT SAID METHOD AND ROTARY PISTON ENGINE SHAFT RPM REGULATOR Russian patent published in 2010 - IPC F02B47/02 F02B53/08 F02B55/10 F01C1/32 F01B25/12 F02D1/04 G05D13/14 

FIELD: engines and pumps.

SUBSTANCE: proposed method is implemented with help of thermal cycle comprising internal combustion cycle and heat exchange cycle of thermal losses collection. Internal combustion cycle consists of four strokes: fuel suction, compression work stroke and exhaust. Heat exchange cycle of thermal losses collection is implemented via water flow through channels of heat exchange between hot section casing and water cooling of combustion chambers. Using these cycles in engine working stroke comprises additionally heating water to boiling point for subsequent injection into combustion chamber. Engine internal combustion cycle additionally comprises steam cycle that represents boiling water (vapor) injection into combustion chamber to increase working body temperature two times and to produce steam-gas mix. Besides heat exchange cycle of thermal losses collection comprises also forcing water via exhaust pipe heat exchange channels and subsequent use of water heated in steam cycle.

EFFECT: higher efficiency.
