INTERNAL COMBUSTION ENGINE Russian patent published in 2009 - IPC F02B53/08 F01C1/73 

FIELD: automotive industry.

SUBSTANCE: invention is intended for automobile engine engineering industry. The internal combustion engine includes cylindrical hosing installed on axle so that the above axle can rotate with regard to housing creating hollow between inner surface of the cylindrical housing and outer surface of axle. The partition separates the above mentioned hollow into two toroidal operating cavities. The rotor piston and choke split the first operating cavity into combustion chamber and exhaust chamber. The rotor piston and choke split the second cavity into suction chamber and compressor chamber. The engine is provided with inlet valve, outlet opening, bypass header with valves installed in the housing between operating cavities, injector and spark plug. The chokes are implemented as rotor pistons. All rotor pistons are installed on common axle so that they can rotate with regard to axle and periodically connect to the above axle. In addition the engine is provided with rotor piston position sensors and rotor piston position holders, installed in the above pistons.

EFFECT: improved efficiency factor and power characteristics, reduced weight of engine.
