ABSTRACT:
Timing increment signals produced by an engine driven tachogenerator are used for controlling both ignition timing shift and the dwell time of the interruptor switch of the ignition system. Counting of increment pulses by the ignition coil primary current rises to a predetermined value (Io) are measures a dwell time fraction and provides a count result that goes into a computation of which the result measures the duration of a counting of increments between the end of one dwell time and the beginning of the next. For better dynamic behavior the count value representing the dwell time fraction (.beta.t) is corrected in a calculating stage (16-18) by a factor which represents the proportional change in the duration of an increment signal (such a signal at a fixed point in the cycle to the most increment signal).
