  • Ignition system and apparatus and method for generating timing signals therefor
    Patent number: 4014308
    Abstract: A capacitive discharge type ignition system is arranged for selective operation by timing signals generated by either breaker points or a breakerless timing signal generator. The generator utilizes the signal generated by an inductive pickup to modulate an oscillator output. The modulation signal is detected and by use of a peak point detector and converted to accurate timing pulses. Circuitry is included to bias the oscillator in a linear mode and inhibit timing signal generation at turn on until the oscillator is operating stably.
