Abstract:
A rotary engine comprising:a) a static toroidal cavity including: i) an inlet port for introducing fuel and air to said cavity; and ii) an outlet port for exhausting products of combustion from said cavity; b) a first power train able to rotate in a first direction within said static cavity, said first power train including a first output shaft; c) a second power train able to rotate in said first direction within said static cavity, said second power train including a second output shaft; d) a plurality of pistons positioned around a perimeter of said toroidal cavity and between said first and second power trains, said plurality of pistons being movable with respect to said cavity, said plurality of pistons including a first set of pistons connected to rotate with said first power train and a second set of pistons connected to rotate with said second power train and defining a plurality of chambers therebetween said plurality of pistons, wherein combustion of a fuel air mixture within a first one of said plurality of chambers causes a fuel gas mixture to be introduced into a second one of said plurality of chambers through said intake port, combustion material to be exhausted from a third one of said plurality of chambers and one of said first and second drive trains to rotate in said first direction, wherein a subsequent combustion of a fuel air mixture in one of said plurality of chambers causes the other of said first and second drive trains to rotate in said first direction, said first and second drive trains alternating movement upon subsequent combustions; e) said first and second drive trains further including means for stopping movement of the first and second drive trains thereby controlling the amount of rotation of said first and second drive trains and a maximum and minimum angular size of each of said plurality of chambers.
