ROTARY INTERNAL COMBUSTION ENGINE Russian patent published in 2018 - IPC F01C1/67 F02G1/44 

FIELD: engine devices and pumps.

SUBSTANCE: engine comprises two working units 1 and 2, each of which has a cylinder, inside of which two rotors are installed, a conversion device 16 of rotors oscillatory motion into rotary motion, comprising two converter units 38 and 39, inlet and outlet manifolds 58, 59. Each block 38 and 39 has a cam in the form of a flat plate with a profiled hole 40. Each cylinder has a prechamber spark plug 31 which is located in close proximity from top dead point of the device 16, with minimum distance between adjacent pistons lying in axial longitudinal plane of hole 40 symmetry. Each manifold 58, 59 have angular size smaller than the angular size of the piston, their centers are located at a definite angle, a nozzle 33 which working hole angle is calculated according to formula.

EFFECT: reduction of mechanical losses and engine dimensions, increase of its service life and reliability.
