Abstract (en)
[origin: WO9200454A1] The proposal is for an ignition system for internal combustion engines with double coils and semiconductor components in the secondary circuit which cause a steep increase in the ignition voltage. The semiconductor components are preferably switching diodes in cascade which ensure that the ignition voltage is not abruptly applied to the sparking plugs until a predetermined value has been reached. An even steeper increase can be achieved if the breakover voltage of each semiconductor component is matched to the length of the ignition lead.
