FIELD: engines and pumps.
SUBSTANCE: invention relates to automotive industry. Proposed engine comprises compressor, toothed two-rotor engine, systems of gas distribution, fuel feed, cooling, lubrication and control. Air injection and compression and off-gas exhaust are performed at a time with working stroke. Every rotor of toothed two-rotor engine is provided with one working tooth. Gas distribution drum is arranged ahead of combustion chamber inlet. Said drum is shaped to hollow cylinder housing impeller running in air cushion. Compressed air forced from screw compressor receiver is fed to aforesaid drum via face wall opening and, therefrom, via bypass channel arranged along drum cylindrical wall, into combustion chamber. After engine start and warm-up, additional nonpolluting working strokes for extra engine cooling may be used by feeding sprayed water in combustion chamber instead of fuel. Water can convert into steam after heat exchange with engine inner parts. Steam pressure acts of cross-section area of two working tooth to be transformed into rotation with positive torque at engine output shafts.
EFFECT: higher efficiency, power output and reliability, nonpolluting engine.
