FIELD: power engineering; heat engines of various application, including road, air and water vehicles, space plants and high power output industrial thermoelectric plants. SUBSTANCE: proposed rotary engine has housing accommodating driving rotor with sealing projection and driven rotor with two sealing edges and cavity on external cylindrical surface. Rotors are installed for unidirectional rotation. Heating chamber arranged in housing is placed in communication with combustion chamber and expansion chamber through distributing bypass valves on driven rotor and in housing. Rotor profiles are screw type. Antechamber made in housing accommodates recuperative heat exchanger. EFFECT: increased fuel economy and enhanced ecological characteristics of engine. 9 cl, 10 dwg
