Abstract
Disclosed is an ignition control apparatus for controlling the ignition timing of spark plugs mounted in an internal combustion engine. The ignition control apparatus includes a C-MOS type electrical circuit for generating a control signal of the spark plugs based on a fixed spark-advance angle. At the time when the engine is started, the control signal provided from the C-MOS type electrical circuit is used for controlling the ignition timing of the spark plugs.
