  • Electronic ignition circuit with automatic control advance
    Patent number: 4697570
    Abstract: An electronic ignition system for a magneto-operated internal combustion engine eliminates Zener diodes as nonlinear elements for control of the advance and employs a unilateral switch utilizing a diode feedback element to provide a logarithmic response for controlling a SCR which is thereby triggered into conduction to discharge a capacitor and fire a sparkplug.
    Type: Grant

  • Ignition circuit, especially for magneto-triggered internal combustion engines
    Patent number: 4610237
    Abstract: An electronic ignition circuit for a magneto engine utilizes a nonlinear network which responds to the low voltage signal developed in the magneto to control an electronic switch triggering the discharge of a capacitor through a high voltage coil for firing the spark plug so that the system provides automatic advance by virtue of the shift in response to the magneto signal in the nonlinear circuit.
