ABSTRACT:
A boosting mechanism of two-stroke engine, including a turbo-propeller disposed on a mandrel of an activating shaft. The turbo-propeller is positioned in front of an intake port of the combustion chamber of an engine and coupled with a crank of the piston of the engine. By means of rotating the activating shaft, the turbo-propeller is rotated along the activating shaft. Also, the turbo-propeller is synchronously operated with the piston to sweep mixed gas into the combustion chamber so as to maintain a proper oil-gas ratio and increase gas pressure and enhance combustion efficiency and power of the engine.
