PURPOSE:To supply sufficiently ignition energy in a high speed engine by distributing output signals of a current supply angle control circuit according to the output signal of a gate circuit for providing logical outputs of each angle detecting signal and the output of a flip-flop circuit. CONSTITUTION:A gate circuit 13 composes a signal (m) of distributed ignition timing calculating output for a first cylinder and a signal (q) of current supply angle control output to turn on/off a transistor 15 according to the composite output signal I and turn on/off the primary current of a first ignition coil 17 like a signal K. Similarly the gate circuit 14 composes a signal (n) of distributed ignition timing calculating output for a second cylinder and a signal (r) of current supply angle control output to turn on/off a transistor 16 according to the composite output signal J and turning on/off of the primary current of a second ignition coil 18 like a signal L. Thus, even in a high speed engine, shortage of current supply time to the ignition time is precluded and sufficient spark energy can be provided. |
