ABSTRACT:
A rotary internal combustion engine includes a stationary housing having one or more housing slots extending to a housing interface surface and a rotor, having one or more rotor slots extending to a rotor interface surface turning adjacent to the housing interface surface. A piston and an adjacent vane are slidably mounted in each housing slot, and an intake valve is included to open each housing slot to an intake port. A spark plug is mounted in an outer surface angularly adjacent to each housing slot. The rotor includes cam surfaces to impart motion to each intake valve, piston, and vane. As each rotor slot moves adjacent to each housing slot, a vane is moved into the rotor slot and an intake valve is opened. A mixture of air and fuel floods the space of housing and rotor slots outside the piston on one side of the extended vane, while exhaust gasses from previous combustion are forced out of the space on the opposite side of the extended vane, through an exhaust port, by the motion of the rotor. The intake valve is then closed, and the air fuel mixture is compressed by an outward motion of the piston. The spark plug is activated to ignite this mixture, and the resulting expansion of gasses with combustion propels the rotor by pushing on the leading surface of the rotor slot. The vane and piston are withdrawn into the housing slot before impact with the trailing surface of the rotor slot.
