Abstract
An engine comprising one pair of scavenge ports alternately covered and uncovered by a piston, a richer air-fuel mixture and a leaner air-fuel mixture being separately fed into the cylinder from the scavenge ports, the richer air-fuel mixture flowing into the cylinder towards the inner wall thereof, located opposite the exhaust port, and the leaner air-fuel mixture flowing into the cylinder so that it overlays the richer air-fuel mixture.
