More Information
Summary:In an ignition system for an internal combustion engine which is operable in synchronism with rotation of the engine to switch on and off a primary current in an ignition coil and applies to a spark plug a high voltage induced in the ignition coil secondary winding upon the off switching, a Zener diode is connected to the low-voltage side of the ignition coil secondary winding in order to prevent a secondary voltage induced upon the on switching of the primary current from being applied to the spark plug.
