ABSTRACT:
An air flow system for circular rotary engines which provides external air intake for engine cooling and combustion chamber pressurization and faciliates increased fuel efficiency and performance for either air/fuel intake and pressured fuel injection engines. In a circular rotary engine having opposed piston rotors, exterior air is drawn into the engine through intake slots in the engine housing and is then internally pressured in opposite directions by the blades of a central separator fan toward the backside of piston rotor cooling vanes, then directed internally to impeller fans at opposite ends of the engine to increase the air flow pressure for combustion chamber injection and produce piston rotor by-pass air flow for surface cooling. In a circular rotary engine having a single piston rotor and rotor guide flange, exterior air is drawn into the engine through intake slots in the engine housing and is then directed in opposite directions by the surfaces of the rotor and guide flange surfaces toward the backside of the piston rotor cooling vanes, then directed internally to the impeller fans at opposite ends of the engine.
