ABSTRACT:
A time period during which current is conducted through a primary winding of an ignition coil of an internal combustion engine is calculated in response to signals corresponding to an actual rotational speed of the engine and the magnitude of a power supply voltage which is applied to the primary winding, respectively. A time for initiating the primary winding current is controlled in accordance with the calculated time period. Such current is conducted for a maximum period of time, which is determined in response to the magnitude of the power supply voltage, so as to avoid excessive heat build-up in the ignition coil. The rotational speed of the engine is determined by counting clock signals during time intervals which correspond to predetermined angular segments of rotation.
