A rotary piston engine (20) includes a housing (22), a toroidal working chamber having an inlet and exhaust ports (56 and 54), and first and second piston assemblies (30 and 32), having at least one pair of diametrically opposed pistons (30A and 30B, and 32A and 32B), are located in the working chamber. The piston assemblies (30 and 32) are connected to an output shaft through a differential (78), and a Sakita type 1 gear (74A or 76A) and a Sakita type 2 gear (74B or 76B). The piston assemblies (30 and 32) rotate at variable speed, whereby pistons of the slower speed are trailing during portions of the power and intake phases of engine operarion. The Sakita type 1 gear includes teeth in the form of rollers and spark plugs embedded within piston assemblies (30 and 32) are accessible from outside. |
