ABSTRACT:
An engine running control apparatus includes a full-closure state detecting device for outputting a full-closure detection signal when the throttle valve is in the fully closed state, a control device for controlling the open degree of the air control valve, a time-measuring device for counting up a predetermined period of time in response to the full-closure detection signal, an engine speed detecting device for detecting the rotating speed of the engine and an initial value setting device for setting up an engine speed at which control of the degree of the opening is started by the control device, in response to the full-closure detection signal. In this configuration, the control device, in response to the reception of the full-closure detecting signal, fixes the opening of the air control valve until the time-measuring device counts up to a predetermined period of time, and controls the opening of the air control valve after the elapse of the predetermined time so that the engine speed will be reduced at a predetermined rate over time.
