TWO-SECTION ROTARY ICE Russian patent published in 2014 - IPC F02B53/08 F01C1/344 F01C19/04 

FIELD: engines and pumps.

SUBSTANCE: invention relates to propulsion engineering. Proposed internal combustion engine comprises stator unit with two cylindrical chambers. Said chambers houses first and second rotors. Said rotors are fitted in stator chambers with run-out and coupled by common shaft. Blades are fitted in radial slots of the rotors. Stator cylindrical chambers accommodate first and second free running cases arranged between blades of the first and second rotors and inner cylindrical surface of stator chambers. First rotor adjacent blades, first rotor outer surface and inner surface of the first free running cases make the suction-compression chambers. Second rotor adjacent blades, second rotor outer surface and inner surface of the second free running cases make the combustion chambers. Section-compression chamber of the first rotor is communicated via bypass channel with second rotor combustion chamber. Swivel seals are fitted at the ends of first and second rotor blades. Contact part of first rotor swivel seal and inner surface of the first free running case feature equal curvature. Contact part of second rotor swivel seal and inner surface of the second free running case feature equal curvature.

EFFECT: higher power output, efficiency and reliability.
