Abstract
PURPOSE:To improve silence in low rotation region and output in medium and high rotation regions by providing a control valve in a tail tube connected to a muffler and making the opening speed of the control valve higher than the speed of increasing exhaust pressure in the medium and high rotation regions. CONSTITUTION:Two tail-tubes 4, 7 are connected to a muffler 3, and a control valve 5 is provided in the control tail pipe 4. An actuator 17 is connected to the control valve 5 through a wire 16. In a low rotation region, the control valve 5 is closed to discharge the exhaust gas through the tail tube 7. When the rotating speed exceeds a preset value, the control valve 5 is opened at high speed by the actuator 17 to restrain an increase in exhaust pressure, so that output can be improved.
