ABSTRACT:
A rotary internal combustion engine block has a toroidal combustion chamber of circular section. At least four pistons fitted in said chamber perform discontinuous unidirectional circular motion about the center of the toroidal combustion chamber. At various stations about the torus, an air-fuel mixture is introduced between adjacent pistons, the adjacent pistons approach each other resulting in compression of the air-fuel mixture, the mixture is ignited, and gas expansion drives the adjacent pistons apart. The mechanical energy of the pistons being moved apart by the gas expansion is coupled through a drive shaft to the load.
