FOUR-STROKE ROTARY-PISTON INTERNAL COMBUSTION ENGINE Russian patent published in 2010 - IPC F02B53/02 F02B55/02 F01C1/67 

FIELD: engines and pumps.

SUBSTANCE: invention relates to machine-building industry. Four-stroke rotary piston internal combustion engine consists of suction, compression, combustion and exhaust chambers formed as a result of rotation of rotor relative to stator. Distance between suction channel and exhaust channel is equal to the piston width. Angular width of piston is 90° minus shift angle of rotating shaft per combustion cycle. Volume of compression chamber is decreased in comparison to volume of combustion chamber. Spark plug is installed with shift through an angle of 180° in the direction of rotation of piston in stator from the beginning of suction channel hole. Rotor consists of two hubs put on rotor rotation shaft and freely rotating on it. On the flange of each hub there fixed in circumferential direction are two rectangular pistons with internal cooling cavity, which are shifted relative to each other through an angle of 180°, which are inserted in the gaps between two rectangular pistons fixed on flange of opposite hub. Under rectangular pistons of rotor, on flanges of hubs there fixed are pieces of cylindrical tubes. Glands and anti-friction compression rings are installed between pieces of cylindrical tubes and between flanges of hubs and the stator cylinder. Differentia is installed between internal sides of hubs and rotation shaft. On external sides of the rotor hubs between side covers of the stator there installed are rectangular piston rotation controls.

EFFECT: improving performance characteristics of engine.
