Abstract
A rotary piston engine having fuel-air inlets controlled by the piston and which supply a stratified charge to the inlet chamber of the engine. The inlets comprise first inlets which are opened first and which supply a lean mixture along the sides of the cavity in which the piston moves and second inlets which supply a rich material to the central region of the cavity. Ignition of the rich mixture promotes complete combustion with a minimum of undesired combustion products, such as oxides of nitrogen, carbon monoxide, and the like.
