ABSTRACT:
An engine with a single correct direction of rotation and one or more pairs of two-sided rotary pistons (22A and 22B, 38A and 38B, 46A and 46B) with the two pistons of one pair having continuous, overlapping torque production for self-starting operation. Each pair of multiple pairs of pistons and their housings (24A and 24B, 40A and 40B, 48A and 48B) have identical cross sections and graduated thickness relative to the other pairs to sustain multiple expansion. Two sets of inlet valves for fuel, oxidizer and liquid (58A, 60A, 62A and 58B, 60B, 62B) feed two aphodid type combustion chambers (54A and 54B) at the inlet ports (26A and 26B) in the smallest volume pair of housings (24A and 24B). The relative locations and orientations of the eccentrics of output shaft (20), pistons, housings and inlet and exhaust ports (26A, 26B, 28A, 28B, 42A, 44A, 44B, 50A, 50B, 52A, 52B) together with the timing and relative mass flows of valve operation controlled by engine control means (72) secure the correct direction of rotation, multifuel operation and, with multiple pairs of pistons and housings, minimal non-working volume and multiple expansion. Input controls (76) enable precise adjustment of power output and degree of expansive working.
