Title: Vortex automotive combustion engine

Abstract: A spark ignition internal combustion engine is provided with a symmetric open torus combustion chamber at the end of a cylinder with a coaxial inlet for intake of fuel air mixture into the chamber and a coaxial outlet communicating with the upper end of a dome shaped piston into the cylinder. Exhaust valves are symmetrically located within the engine and communicate with the cylinder below the combustion chamber. A spark plug is positioned to locate the spark chamber wall at the outermost diameter of the combustion chamber. The inlet is provided with a swirl inducing device to induce the fuel/air mixture to swirl around the circumference of the combustion chamber by centrifuge of liquid fuel droplets onto the walls thereof and thereby stratify the charge in the combustion chamber.
