Rotary internal combustion engine

A rotary internal combustion engine, comprising:

• a) an outer housing having a circular inner periphery;
• b) a rotor mounted for rotation within said housing, said rotor including
• 1) a rotor shaft coaxially arranged within said housing and rotatable thereon,
• 2) a radially extending rotor portion mounted on the rotor shaft and including cavities that extend between the outer periphery of said rotor and the rotor shaft;
• c) a piston pivotally mounted in each cavity in said rotor for movement between a position adjacent the outer periphery of said rotor and a position adjacent said rotor shaft, said piston dividing said cavity into a pair of air compression chambers, one of said chambers being a combustion chamber;
• d) means cooperatively engaging said rotor, said pistons, and said housing whereby rotation of said rotor in relation to said housing causes said pivotal movement of each said piston in its respective cavity;
• e) means for injecting water into one of said air compressed chambers;
• f) means for injecting fuel into one of said air compression chambers, the injection of said fuel following the injection of said water and being effected in each chamber at a time correlated to the positions of the other pistons in their respective cavities whereby combustion of the air-fuel charge in said chamber effects vaporization of the water contained therein and rotation of said rotor.
