ABSTRACT:
An ignition control apparatus for an internal combustion engine is disclosed in which the ignition energy for igniting by means of a spark plug the air-fuel mixture supplied to the internal combustion engine is controlled in accordance with the flow velocity of the air-fuel mixture flowing in the neighborhood of the spark plug. An ignition coil for supplying a spark ignition voltage to the spark plug is energized by a power supply and de-energized at the desired timing of spark generation in accordance with the operating conditions of the internal combustion engine. The rotational speed of the engine representing the flow velocity of the mixture is detected and on the basis of this detected rotational speed, the duration of energization of the ignition coil is variably controlled.
