ABSTRACT:
Disclosed are apparatus for a two cylinder rotary internal combustion engine comprising a stationary cylinder block with a pair of inwardly facing horizontally opposed pistons operating within. Each piston is maintained in fixed relationship to the other by means of a common connecting rod. A cam roller assembly is included at each outer extremity of the opposed pistons for transmitting reciprocating motion to an eccentric cam raceway provided within an outer rotating frame assembly which is rotably mounted with respect to the stationary cylinder block. An output drive shaft is connected to the rotating frame. Tubular cylindrical intake and exhaust valves communicate with each cylinder, with a geneva drive mechanism provided for imparting stepwise counter-rotational motion to said valves for admitting combustible mixture and exhausting combustion gasses at proper intervals. In a preferred embodiment, a four cylinder rotary engine is illustrated comprising two pairs of horizontally opposed piston with two eccentric cam raceways arranged for mechanically balanced operation in a four cycle engine having two power strokes per revolution.
