Abstract

PURPOSE:To improve the scanvenging efficiency and increase the power of an engine by arranging in exhaustion system a turbine driven by the high speed gaseous flow at the initial period of exhaustion and sucking up the exhaust gas by the pumping operation of the turbine at the terminal period of exhaustion. CONSTITUTION:A gas exhausted from an exhaust port 3 in the exhaust stroke of a two-cycle engine is introduced into the turbine 9 within an exhaust passage 6 as a high-speed jet to rotate a moving blade 14 supported by bearings 17 and 18 between stator blades 13 and 15. In the terminal period of exhaustion where the moving blade 14 is rotated, the pressure at the turbine inlet lowers, as a result of which the pressure within the combustion chamber is decreased through the exhaust port 3. Therefore, particularly in the high-speed rotation zone, it is possible to increase the quantity of the sucked air into the combustion chamber and also to expect the improvement in the scanvenging efficiency and the power increase.
