  • Patent number: 4399801
    Abstract: Our overrun prevention ignition system of the capacitor discharge type includes an ignition angle retarding circuit for retarding the ignition angle by an overlapping period between an ignition signal and a predetermined conduction period of a switching transistor associated with an ignition controlling thyristor. The ignition angle retarding circuit includes an ignition signal generating coil sharing a common core with a magneto and includes a capacitor which is charged by a portion of an ignition signal from the ignition signal generating coil. The capacitor discharges for a certain period upon commencement of the decay of the ignition signal to produce a supplemental ignition signal thereby to effectively lengthen the width of the ignition signal. A switching transistor connected to the gate of the ignition controlling thyristor is maintained conductive for a predetermined period of time irrespective of the engine speed to bypass the ignition signal during this period.

  • 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.

  • Patent number: 4343273
    Abstract: An ignition system of the capacitor discharge type and capable of preventing overrunning of an internal combustion engine includes a control circuit to render a switching transistor connected to a gate-cathode circuit of a main thyristor conductive for a predetermined period of time to interrupt a backward or reverse phase voltage generated by a magneto and serving as an ignition signal for the main thyristor from being applied thereto. The control circuit includes an integrator circuit connected in parallel with a constant voltage source to develop a voltage increasing with time and includes a voltage divider of the constant voltage source to provide a reference voltage. A transistor circuit of the control circuit compares the output voltage of the integrator circuit and the output voltage of the voltage divider and the transistor circuit maintains a control signal to be applied to the transistor circuit until the output of the integrator circuit reaches the reference voltage of the divider.
