Abstract
A magnetic ignition system with an ignition coil primary circuit having an ignition switch is controlled by a control switch to break at a given ignition time so that an ignition voltage is induced in the secondary circuit. A signal is delivered by a control circuit between the voltage supply and earth via resistors to a control switch at the ignition time. The control circuit serves the functions of voltage limiting and prevention of double spark (retriggering).
