Capacitor discharge ignition (CDI) system

摘要

This invention relates to an improved Capacitor Discharge Ignition (CDI) system capable of generating intense continuous electrical discharge at spark gap for any desired duration, characterized in that it includes a second controllable power switching means with its input terminal connected to the output terminal of said high voltage d.c. source means, its output terminal connected to the input terminal of said first power switching means, and its control terminal connected to a second output of said control means, the arrangement being such that said first controllable power switching means is used for discharging said discharge capacitor and said second controllable power switching means causes charging of said discharge capacitor, thereby enabling an ignition current through said ignition coil for any desired number of cycles during both the charge and discharge cycles of said discharge capacitor.
