ABSTRACT:
In a four stroke cycle reciprocating internal combustion engine, four dual functionable combustion chambers and two power trains to crankshaft are comprised of a single stationary cylinder encasing two quadruple faced rotor-reciprocative pistons, further encasing a rotatable intake-exhaust manifold geared to an external rotatable crankshaft. The crankshaft is connected by connecting rods to driving arms on external extensions of the two pistons.
Two such units connect to a common crankshaft to comprise an eight combustion chamber engine.
Upon each crankshaft half turn stroke the two pistons of a unit and associated intra-engine power trains to the crankshaft move simultaneously in opposed directions to expand two chambers for intake and combustion and to contract the other two for compression and exhaust functions. On each successive stroke the pistons reverse directions, the chambers reverse expansive and contractive actions, and the manifold rotates one quarter turn to advance each function to the succeeding chamber. In the dual opposed piston and power train action, each piston serves as a working compression head for the other, thus providing a high work to low heat loss ratio for the chambers and a high degree of balance with low friction to the engine bearings. A highly turbulent fuel-air mixture injected toward the hot area that bounds each spark plug assures a high percent of fuel burn with minimal air pollution.
