ABSTRACT:
An electronic ignition system comprising an ignition coil, having the spark gap in circuit with its secondary winding, a primary transistor and a current limiting circuit in circuit with its secondary winding, a filter transistor connected in front of said primary transistor and controlled by a control signal and a resistor network connected in the current path of the filter transistor, the filter transistor and the resistor network being so dimensioned that, during a rise in current in the primary winding, the further transistor is in saturated operation and a jump in the voltage across the resistor network to a constant maximum voltage when the current is limited by the current limiting circuit, a pulse being derivable from the voltage curve at the resistor network.
