PURPOSE:To secure high charging pressure and high torque following it in low speed region of engine by driving the adjusting valve established in the exhaust manifold with adjusting unit actuating in accordance with variation of exhaust amount. CONSTITUTION:By-pass 5 is established between exhaust manifold 3 and suction duct 4, and reverse stopping valve 6 prevents exhaust gas from flowing into suction duct 4. In low speed and low negative pressure, adjusting valve 7 removes to a position of imaginary line by adjusting unit 8 because sucked pressure to be led in a chamber 88 is low. The temperature air within suction duct 4 flows into scroll 13 through reverse stopping valve 6 and strengthenes turbine 11 together with exhaust gas flowing from scroll 14. Thus high sucked pressure and high torque following it can be gained in a low speed region of the engine. |
