制御型消音装置。[Claims for Utility Model Registration] (1) A first exhaust pipe provided with a control valve and a second exhaust pipe not provided with a control valve, and the control valve is activated when the engine speed is below a set value. The control type silencer is configured to close the control valve and open the control valve when the engine speed exceeds a set value, and is characterized in that the control valve is divided into two parts, each of which can be rotated separately. Controlled silencer. (2) A control valve divided into two parts closes two control valves or closes one control valve when the engine speed is below a set value, and opens both control valves when the engine speed is above the set value. A controlled silencer according to claim 1, characterized in that it is configured to do so.
