FIELD: engines and pumps.

SUBSTANCE: invention relates to propulsion engineering. Rotary engine comprises control system with control unit, housing, crankshaft with main and rod journals, external engagement gear, combustion chamber arranged between said housing and rotor, rotor radial seals, intake and exhaust pipes, choke and fuel injector. Rotor with internal engagement gear is arranged inside said housing. External engagement gear is rigidly fitted on fixed sleeve aligned with crankshaft main journals. Choke is arranged in intake line. First fuel injector is fitted downstream of said choke. Combustion chamber is composed of the main combustion chamber and prechamber. At least one spark plug and second fuel injector are secured to said prechamber. Cavities are made under radial seals communicated via holes with the part of inner cavity confined by rotor end and internal engagement gear. Oil feed injector connected with high-pressure oil line is arranged between internal and external engagement gears. High-pressure oil line is connected with oil pump outlet. Oil pump inlet is connected with inner cavity bottom.

EFFECT: higher reliability and efficiency, lower offgas toxicity.
