うことができるという優れた効果がある。As described above, in the present invention, each capacitor is charged by the output of the capacitor charging coil, and the first output of the timing signal generator conducts a predetermined cyrisk to generate an ignition spark in a predetermined cylinder. , the polarity of the output of the capacitor charging coil is detected and the thyristors of the other cylinders are made conductive, and both thyristors are connected in series, and when the second output of the timing generator is generated, both thyristors are made conductive and the thyristors of the other cylinders are made conductive. Since ignition sparks are generated at the same time in the cylinder, only one timing signal generator can generate multiple ignition signals and, if necessary, charging control signals.
Multiple discharge circuits are independently controlled by the ignition signal generated by the timing signal generator, and each cylinder has 90° and 270° crank unequal ignition intervals with a simple configuration and low cost.
An excellent effect is that independent ignition for multiple cylinders such as 80° crank ignition can be performed.
