FIELD: engines and pumps.
SUBSTANCE: rotary internal combustion engine with emulsion air-oil lubrication system circulating under pressure consists of two cylindrical stators. One stator is intended for zones of operating stroke, and the other one is intended for compression zone. Two floating rotors are located concentrically in stator of operating stroke zones on working shaft (with splined fit) and have the periphery of boundaries of working surface, which allows the rotor operation at slit chamber of operating stroke with provided duration of one operating stroke with an angle of up to 540 degrees of revolution of each rotor. In stator of compressor zone there located is floating sector rotor with projecting pistons with circular working surface, with proper rotation axis, and with actuation from working shaft through reduction gear-converter. Engine has system of channels, high pressure tubes, annular channels, micro channels, which allow the engine lubrication by arranging the constant circulation under pressure of air-oil emulsion through the engine. Combustion chambers with gas expansion nozzles are located in stator in each operating stroke zone. On inner stator surface of operating stroke zone there arranged after the nozzle is gas expansion flame course spreading to the exhaust manifold opening, with diameter that is larger than working surface of rotor by the value of gap providing the action of circumferential force of gas expansion on projecting pistons of rotors, and which is provided with a gap that is reduced towards the exhaust manifold.
EFFECT: higher operating efficiency of the engine.
