ABSTRACT:
A capacitor discharge ignition (CDI) system for a light-duty spark ignition combustion engine includes an analog control circuit having a charging circuit, a trigger circuit and a shutdown circuit. In response to activation of a kill-switch, the shutdown circuit causes a switching device to discharge an ignition capacitor. Through the use of an RC circuit, the switching device continues to be biased such that it prolongs the discharge of the ignition capacitor, thereby preventing it from storing charge for the upcoming ignition pulse. This generally continues until the engine has come to a stop, at which time the engine can be immediately restarted without having to reset anything. The control circuit may also include engine speed limiting and ignition timing features.
