Abstract
An engine is disclosed including at least one piston which is positioned within a toroidal piston chamber. A method of operating an engine is disclosed wherein a piston is advanced in a toroidal piston chamber past a first valve and the first valve is closed to form a first ignition chamber area located within the piston chamber between the first valve and the rear side of the piston. A second valve is closed ahead of the piston to form a first exhaust removal chamber area located within the piston chamber between the second valve and the front side of the piston, the exhaust removal chamber including exhaust gases from a preceding ignition which occurred in the first ignition chamber area. A fuel mixture is introduced into the first ignition chamber area and ignited thereby advancing the piston further along the toroidal piston chamber.
