期制御装置。 In an ignition timing control system for an internal combustion engine, which is equipped with a vacuum advance device that drives the breaker plate of the distributor using intake pipe negative pressure, and a first idle cam device that increases the opening of the throttle valve when the engine is cold. An advance negative pressure port opens into the intake pipe facing the valve end of the throttle valve at the open position, and an intake negative pressure port opens into the intake pipe on the downstream side of the throttle valve. A three-way switching valve is provided that selectively communicates with the vacuum advance device, and a means for detecting the cold state of the engine, a means for detecting that the throttle valve is at the idle opening, and a means for detecting the cold state based on both detection means. An ignition timing control device for an internal combustion engine, comprising means for controlling a three-way switching valve so as to communicate a vacuum advance device with an intake negative pressure port only when the throttle valve is at an idle opening.
