The disclosure is directed to a control device for an internal combustion engine for a motor vehicle such as an automobile or the like, having a control valve disposed in a by-pass passage for opening and shutting the by-pass passage which communicates the upstream side and the downstream side of an intake passage by by-passing a throttle valve, in which the engine speed in idling operating condition is controlled to a target speed. This control device is characterized in that the ignition timing is rather advanced than ordinary idling ignition timing during a certain period from the instance when the engine has entered into the idling operating condition after having received a signal detecting the idling operating condition of the engine.

A control device for an internal combustion engine which comprises: an ignition timing setting means for setting an ignition timing of said engine; an idling detecting means for detecting an idling operating condition of said engine; an idling speed control means for controlling the idling engine speed to a target speed by controlling the amount of intake air after having received a signal from said idling detecting means; a deceleration detecting means for detecting whether said engine has decreased into an idle operating speed range; and an ignition timing correcting means for advancing said ignition timing set by said ignition timing setting means relative to ordinary idling ignition timing when said engine has entered into said idling operating condition after detection of deceased speed of said engine by said deceleration detecting means by receiving said signal from said idling detecting means and a signal from said deceleration detecting means, said ignition timing correcting means maintaining the advanced ignition timing during a predetermined time of the idling operating condition of said engine.
