Abstract
A two cycle internal combustion engine with improved cylinder scavenging. The described engine embodiment is a baffled piston two cycle internal combustion engine whose power is substantially increased by directing fuel mixture in the normally spent gas filled region behind the piston baffle during each intake-exhaust portion of the engine cycles to scavenge spent gas from this region and increase the total volume of fuel mixture in the cylinder at the time of ignition. According to the preferred practice of the invention a portion of the fuel mixture displaced from the engine crankcase to the cylinder intake port or ports is diverted to auxiliary ports in the cylinder wall which direct the mixture against the rear side of the piston baffle to effect through scavenging of the region directly behind the baffle.
