Abstract
An ignition control apparatus, e.g., for an internal combustion engine, includes a rotational speed calculation unit that calculates a rotational speed of an alternating current generator. A rotor of the alternating current generator is driven to rotate in synchronization with reciprocating motion of a piston of the internal combustion engine. An ignition timing determination unit determines an ignition timing of the internal combustion engine based on the rotational speed calculated by the rotational speed calculation unit. An ignition control unit supplies electric power to an ignition coil such that the internal combustion engine is ignited at the timing determined by the ignition timing determination unit.
