Abstract
A two-stroke engine includes a crankcase. A power cylinder extends from the crankcase. The power cylinder selectively fluidly communicates with the crankcase to scavenge the power cylinder. A power piston is reciprocably disposed in the power cylinder. A compressor cylinder extends from the crankcase. The compressor cylinder selectively fluidly communicates with the power cylinder to introduce a pressurized air/fuel mixture into the power cylinder. A compressor piston is reciprocably disposed in the compressor cylinder.
