ABSTRACT:
The previous ignition timing is used as a starting point for repititive ignition cycles to define the primary coil current flow starting point, in order to secure a sufficient current flow duration for the primary coil current that is supplied to an ignition coil to thereby prevent a shortage of ignition energy. An arithmetic circuit including a central processor produces data representing the duration between the previous ignition timing and the primary coil current flow starting point. A counter starts this counting operation from the previous ignition timing. The primary coil current feed to the ignition coil starts at a time when the contents of the counter are coincident with the result of the processor produced data.
The data is obtained by subtracting a necessary primary current flow duration or time from the interval between the previous ignition timing and the present ignition timing.
