Abstract
PURPOSE:To prevent an engine speed from its drop by fully closing in stages a bypass line despite chattering of an idle switch when an actuator, which drives an auxiliary valve in the bypass line detouring around a throttle valve, is controlled in the direction of valve closing. CONSTITUTION:A regulating valve (auxiliary valve) 4a, controlled opening and closing by a step motor 4, is mounted interposing in a bypass line 6 bypassing a throttle valve 5 in an intake pipe 3. This regulating valve 4a is controlled in accordance with the operating condition of an engine by a control unit 11 which inputs output signals of an idle switch 7, detecting the throttle valve 5 to be fully closed, and a throttle valve opening sensor 8. Here the control unit 11 is constituted controlling the step motor 4, when it drives the regulating valve 4a in the closing direction, so as to close in stages the bypass line 6 despite an on/off condition (chattering) of the idle switch 7.
