FIELD: mechanical engineering; internal combustion engines.
SUBSTANCE: proposed rotary engine has body with cylindrical holes, getting into each other by sides, rotors provided with teeth and tooth space arranged in cylindrical holes of body, valves executing timing, gears synchronizing rotation of rotors, compressed air accumulating tank, lubricating system and sealing members. Body is provided with two or three cylindrical holes. Inner space of body is divided by partition into air intake and compression section and fuel mixture combustion and exhaust section. Engine has two or three detachable rotors, at least one combustion chamber being also expansion chamber (combustion-expansion chamber), intake valve consisting of disk with hole which periodically registers with intake port at rotation of disk. Welded around intake port is sealing bead made of non-hard metal or alloy which is lapped to disk. Pressure compensator is arranged in end face cover. Pressure compensator consists of attachment with cylindrical polished surface fitted on end of auxiliary rotor, cover plate with groove, space, sealing members arranged over perimeter of cover plate, channel connecting space of cover plate with combustion-expansion chamber. Engine is started by compressed air from bottle.
EFFECT: increased efficiency of engine, reduced toxicity of exhaust gases.
