Abstract: An internal combustion rotary engine using vanes to create separate combustion chambers within the engine and capable of performing all four strokes of the Otto cycle (intake, compression, combustion and exhaust) in each separate combustion chamber. Each Otto cycle is completed in a 180-degree rotation with all four strokes of the Otto cycle being completed in 720 degrees. An intake and exhaust valve system tightly controls the flow of the air/fuel mixture into each separate combustion chamber.

Abstract: An internal combustion rotary engine consisting of casing (1) housing a rotor positioned slightly off-center of drive shaft (7) allowing A to displace the fuel/air mixture about the engine chamber. (2) Separating vanes (3) create separate chamber rooms (23) within the engine. Each separate chamber room (23) has its own capability to accomplish the four Otto cycles; intake, compression, combustion and exhaust in a 720-degree rotation of rotor (2). Each chamber room (23) also has its own method for combustion (8) as well as a set of intake valves (4) and exhaust valves (5) which draw in and expel the fuel/air mixture, respectively.

Abstract: A rotary engine consisting of a slightly oblong casing (10) housing a circular shaped rotor (12). Attached to the rotor are separating vanes (14) that slide in and out of the rotor to create separate chambers within the engine. Additionally, the rotor houses inlet valves (16) and exhaust valves (18) which draw in and expel the fuel/air mixture, respectively. The rotor houses the means for manipulating the valves.
