Abstract
An internal combustion engine (10) is provided which includes a wall (12) defining a toroidal cylinder (22). A pair of flywheels (36 and 38) are mounted for rotating with respect to said cylinder (22) on a central axis thereof and with respect to each other. Each of the flywheels carry at least a pair of pistons (50) mounted at selected locations, and preferably 180 degrees apart. These pistons (50) cooperate to define compressing/expanding chambers during rotation of the flywheel. Air and fuel are selectively drawn or injected into the cylinder chambers, ignited and then exhausted from the chambers during engine operation. A device (70) is also provided to control the speed of revolution of the pistons during the engine cycling such that the compression/expansion chambers are defined at selected locations during a cycle of the engine.
