Abstract
PURPOSE:A multi-ignition system which improves the integrating performance by using some reference voltage circuits for comparing circuits as manu as ignition coils, which are provided in a current control circit of an ignition system. CONSTITUTION:This multi-ignition system consists of a pick-up coil 1, a wave matching circuit 2, driver circuits 3, 4, power transistors 5, 6, ignition coils 7, 8, a current control circuit 9, a current-limit-period-operating one-voltage conversion circuit 10, primary-current detecting resistances 11-13, 15-17, Said current control circuit 9 includes a comparing circuit made up by two sets of transistors 903 and 905, 904 and 906. A voltage devided by the resistors 901, 902 connected at a constant voltage source is applied to each base of the Trs 903, 904 as a reference voltage. The terminal voltages of the primary current detecting resistances 13, 17 are used as the comparing voltage of the Trs 905, 906.
