ABSTRACT:
The invention relates to an ignition control device of the microcomputer type in which a programmed microprocessor calculates the non-conduction time of the coil in order to attain a desired time for which the coil remains at maximum charge, and also calculates the time corresponding to the end of coil charge as a function of the spark advance suitable for the various engine operating conditions; the microprocessor also causes activation of the ignition coil, whereas the deactivation of the coil is controlled by a timer which counts the time corresponding to the end of coil charge on receiving reference pulses.
