ABSTRACT:
An ignition arrangement with speed limitation for internal combustion engines in which a trigger pulse actuates a switch for generating a high ignition voltage, particularly a capacitor ignition device with thyristor control. A timing circuit is triggered by a pulse for preventing renewed actuation of the switch by a trigger pulse within a predetermined reference time interval of the timing circuit. The timing circuit, furthermore, short-circuits the control part of the switch. Each trigger pulse actuates the timing circuit only after the switch for generating the high voltage. A transistor is connected in parallel with the control path of the switch, and the transistor's control electrode is connected to the output of the timing circuit switched by the trigger pulse. An electronic discharge switch actuated by the trigger pulse, is connected in parallel to a time-determining capacitor of the timing circuit. Upon reaching a predetermined voltage across the capacitor, the latter resets the timing circuit.
