Abstract
An ignition timing control device is provided that includes an engine load condition detecting device, a failure detecting device and an ignition retarding device. The engine load condition detecting device detects a load condition of the engine. The failure detecting device detects the failure of an idle speed control device. An ignition retarding device retards the ignition timing of the engine by an amount based on the determined engine load conditions when the idle speed control device fails.
