Abstract

PURPOSE:To improve the controllability of an engine speed by controlling an auxiliary valve so as to decrease the actual opening of a dashpot smaller by stages when a throttle valve is fully closed, while the auxiliary valve in a bypass line, detouring around the throttle valve, is driven to the target opening of the dashpot. CONSTITUTION:Mounting a regulating valve (auxiliary valve) 4a, controlled opening and closing by a step motor 4, to be interposed in a bypass line 6 bypassing a throttle valve 5 in an intake pipe 3, this regulating valve 4a is controlled by a control unit 11 in accordance with the operative condition of an engine. Here the control unit 11 is constituted so as to control the step motor 4 in order to reset the target opening of a dashpot to its actual opening thereafter to close the bypass line 6 by stages when an idle switch 7 is turned on (throttle valve fully closed), when the step motor 4 is controlled so as to obtain the target dashpot opening calculated being based on an output of a throttle valve opening sensor 8.
