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.

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.

An engine comprising: (a) a pair of substantially identical stationary housings and (b) a pair of substantially identical, two sided rotary pistons slidably received within said housings at apices of said rotary pistons, and (c) an output shaft rotatably supported by said housings, said output shaft
An engine comprising: (a) a pair of substantially identical stationary housings and (b) a pair of substantially identical, two sided rotary pistons slidably received within said housings at apices of said rotary pistons, and (c) an output shaft rotatably supported by said housings, said output shaft drivably coupled to each said rotary piston to form two variable volume cavities inside each said housing, said rotary pistons having a single, arbitrary, correct direction of rotation, and (d) said housings and rotary pistons oriented relative to each other so that when a major axis, or a line defined by said apices, of one said rotary pistons is in a top dead center orientation relative to its said housing such that said two variable volume cavities are of minimal and maximal volume, other said rotary piston has its own said major axis at a selected angle of not more than half of pi radians, or 90 degrees, relative to its own top dead center orientation in its own said housing, and (e) an inlet port and an exhaust port in each said housing, said inlet port opening into said cavity of minimal volume and located on one side of a plane and adjacent to an intersection of said plane with inside of said housing, said exhaust port being on other side of said plane and adjacent to a second intersection of said plane with said inside of said housing, said plane being defined by one position assumed by said major axis of said rotary piston contained by said housing and rotational axis of said rotary piston, said plane being rotated by a first angle in said correct direction of rotation from a reference plane defined by said rotary piston major axis in said top dead center orientation and said rotary piston rotational axis, said correct direction of rotation being defined as said apices moving away from adjacent said inlet port and adjacent said exhaust port when said rotary piston major axis is at said first angle, and (f) separate inlet valve means for each said inlet port for a working fluid that is at a higher pressure than the pressure at said exhaust ports, said valve means having a total of opening duration plus closing duration such that said total plus duration of traversal by said apex of said exhaust port plus said first angle plus a second angle is less than or equal to said selected angle, the duration defined as angle traversed by said rotary piston major axis during any event, and (g) engine control means that sense angle of each said rotary piston major axis relative to said plane and open said valve means when said rotary piston major axis has rotated said second angle past said plane, sum of said first angle and said second angle being more than zero and less than said selected angle minus the sum of duration of said valve means opening and said valve means closing and traversal of said exhaust port by said apex, and that close said valve means before either said apex enters said exhaust port.
