FIELD: power engineering; cyclic-process engines. SUBSTANCE: working medium used for engine is mixture of several ingredients in liquid and gas phases. Changes in pressure and temperature of such mixtures cause variations in concentration and quantity of phases. Fast expansion and compression processes result in chemical variations of working medium. Engine is designed to provide for conducting expansion and compression processes along with stirring working medium. EFFECT: enlarged thermodynamic efficiency of heat engine. 3 cl, 5 dwg
