Electronic speed control for capacitor discharge ignition system
Electronic shut-off circuit is provided in a capacitor discharge ignition system for internal combustion engines to protect against excessive high-speed operation. The circuit includes an electronic switching component connected across the main capacitor of the ignition system. A trigger coil is connected in circuit with a control electrode of the electronic switching component. The trigger coil is selected to generate a sufficient voltage to bias the switching means to its conductive state, thereby providing a low impedance shunt path to short the capacitor and to prevent it from discharging its energy into the primary of the ignition coil. A resistance-capacitance network, in circuit with the switching component, serves to hold it ''on'' until the engine is shut off.
