ABSTRACT:
A system of capacitive discharge ignition for automobile vehicles with a converter governed by a multi-vibrator, maintains constantly the maximum working current in the power circuit, independently of the feed voltage, by the control of the time of commutation of the multi-vibrator, by using a diode of the Zener type. The diode is connected in parallel with the collector-emitter section of the transistor of the multi-vibrator which is normally shorted to charge the commutation condenser at a fixed voltage which is lower than the lowest value of the voltage of utilization. A transistor with a battery sensor circuit short-circuits part of the resistance of the charging circuit of the condenser when the voltage is higher than a pre-fixed value.
