A rotary-reactive internal combustion engine of the type having a stator and a rotor which is rotatable in one direction, characterized by:
- A. the rotor having
- (1) a shaft with a disc fixed thereto intermediate its ends, said disc having flat and parallel opposite faces,
- (2) two pairs of diametrically opposite cylinders in the disc, each having a round port, said ports having the same diameter, said ports of each pair opening to opposite faces of the disc,
- (3) and a reactive duct in the disc leading to its periphery from each cylinder at an angle of 90.degree. to the cylinder axis, said ducts having the same diameter, said ducts extending in a direction opposite to that of rotor rotation and each terminating in a reactive nozzle at the periphery of the disc, said nozzles extending circumferentially through an angle substantially 8.degree.;
- B. the stator comprising similar left and right stator housings fixed to one another and overlying the opposite faces of the rotor disc, said housings having bearing means to rotatably receive the rotor shaft, said stator having
- (1) diametrically opposite air-fuel admission ports, one in each stator housing, located to be registrable with the cylinder ports during rotation of the rotor, said admission ports having the same diameter as the cylinder ports, and each such admission port having an injector nozzle through which air-fuel mixture must flow to reach its respective cylinder port,
- (2) diametrically opposite spark plugs, one in each stator housing, located in circumferentially spaced relation to its respective admission port by an angle of substantially 30.degree. in the direction of rotor rotation, said spark plug located inside a niche means,
- (3) diametrically opposite exhaust canals, one in each stator housing, to receive combustion gases from the cylinders, each such canal extending circumferentially through an angle of substantially 232.degree. in the direction of rotor rotation from a location adjacent to its associated admission port,
- (4) a first pair of diametrically opposite walls, one in each stator housing, located alongside the rotor periphery and extending through an arc of substantially 68.degree. in a direction opposite to that of rotor rotation, from a location at the end of its exhaust canal first swept by the reactive nozzles in the rotor,
- (5) a second pair of diametrically opposite walls, one in each stator housing, located at the end of its exhaust canal last swept by the reactive nozzles and each such wall extending circumferentially through an angle substantially 8.degree.,
- (6) diametrically opposite admission canals, one in each stator housing, for delivering high pressure fresh air circumferentially to the cylinders, each such canal being located between said first and second pairs of walls,
- (7) diametrically opposite scavenging ports, one in each stator housing, located to be registrable with the cylinder ports during rotation of the rotor, said scavenging port having the same diameter as the cylinder ports and being located substantially 60.degree. from its associated admission port in the direction opposite to rotor rotation,
- (8) an exhaust pipe connected to each stator housing and leading outwardly from its exhaust canal from a location adjacent to its spark plug,
- (9) an admission pipe connected to each stator housing and located to supply high pressure fresh air to its admission canal,
- (10) and an outlet pipe connected to each stator housing in communication with its scavenging port.
