Abstract
In a two cycle internal combustion engine (2), a turbulence generator (70) is provided by a freely rotating fan (72) in the fuel-air stream to the reed valves (16) which supply the fuel-air mixture into the crankcase chamber (8). The freely rotating fan (72) is driven by the fuel-air mixture flow and rotates to generate turbulence to provide more uniform distribution of the fuel-air mixture.
Claims8
A two cycle internal combustion engine comprising a piston reciprocal in a cylinder between a combustion chamber and a crankcase, a reed block mounted to said crankcase and having one or more reed valves and admitting a fuel-air mixture to said crankcase, a fuel-air supply system supplying said fuel-air mixture to said reed block, a turbulence generator in the fuel-air stream to said reed block and generating turbulence to provide more uniform distribution of said fuel-air mixture, said turbulence generator being movable relative to said crankcase and being moved by flow of said fuel-air stream therepast.
A two cycle internal combustion engine comprising a piston reciprocal in a cylinder between a combustion chamber and a crankcase, a reed block mounted to said crankcase and having one or more reed valves and admitting a fuel-air mixture to said crankcase, a fuel-air supply system supplying said fuel-air mixture to said reed block, a turbulence generator in the fuel-air stream to said reed block and generating tubulence to provide more uniform distribution of said fuel-air mixture, wherein said turbulence generator comprises a fan in said fuel-air stream.
