Abstract

PURPOSE:To eliminate the exhaust pulsation during the slew or intermediate speed revolution and prevent the reduction of the engine output by installing a shielding member which can be shifted towards the center part from the outer peripheral edge of an exhaust pipe and whose sectional area can be varied according to the engine revolution speed, onto the opened edge part of the exhaust pipe. CONSTITUTION:An exhaust pipe 2 connected with the exhaust port 3 of an internal combustion engine extends to the downstream side in an equal sectional area from the exhaust port 3, and the opened edge part 10 at the rear edge is opened into the exhaust muffler 11 having a large diameter. In this case, a movable shielding member 13 is installed at the opened edge part 10 of an exhaust pipe 2, and the shielding member 13 is installed in shiftable ways in the vertical direction between an opening position 13a positioned on the peripheral edge part of the exhaust pipe 2 and a shielding position 13b for partially shielding the exhaust pipe 2, and can be shifted by a solenoid 14. The solenoid 14 is controlled so that the shielding member 13 is shifted to a shielding position 13b in a certain revolution speed region (e.g., 2500-8000rpm) by a controller into which the output signal of an engine revolution speed detecting device is inputted.
