  • Ignition system with ignition timing retarding circuit for internal combustion engine
    Patent number: 4344395
    Abstract: An ignition system for an internal combustion engine is provided with an ignition timing retarding circuit to prevent overrunning of the engine. The ignition timing retarding circuit includes a switching circuit connected to the gate of an ignition control thyristor and a predetermined duration signal generator for generating a signal having a predetermined duration from a predetermined reference time. During the time period in which the predetermined duration signal is applied to the switching circuit, the switching circuit is maintained conductive to thereby bypass an ignition signal generated in synchronism with the crankshaft rotation and applied to the gate of the ignition control thyristor.
