Ionescu, D; Soiman, M

An electronic ignition system is described for an internal combustion engine having at least one spark plug and a magneto having at least one magneto coil with a single low-voltage winding in the coil. The system consists of: a charging circuit connected to the winding and providing a rectified output; a discharge condenser continuously connected to the charging circuit and adapted to be charged by the output; a triggering circuit including: an electronic switch having a control electrode, and a high voltage transformer connectable by the switch, when the switch is triggered to the condenser, the spark plug being connected to the transformer for firing when the switch is triggered by the control electrode; and a nonlinear network connected to the winding and logarithmically responsive to a signal generated therein for triggering the control electrode to effect a discharge of the condenser through the transformer to fire the spark plug whereby a firing point is automatically advanced and retarded depending upon the logarithmic response of the nonlinear network.
