Abstract
A combustion apparatus having a housing including an inner surface that defines at least one chamber, a rotor, a rotor shaft, an intake shaft, an exhaust shaft, and a gearing mechanism. The chamber includes an intake valve port and an exhaust valve port, and the rotor shaft is coupled to a gear at one end and has at least two opposing flat surfaces received by an opening in the rotor. The intake and exhaust shafts are geared to the rotor shaft and have at least one opening each that is aligned with the intake and the exhaust valve ports. A gearing mechanism selectively controls the duration in which the openings are aligned with the ports. Two or more rotors may be utilized to produce more power and reduce vibration.
