Abstract

The purpose of the invention is to create an electronic ignition device for internal combustion engines, so that the exact setting of a required ignition timing can be done without troublesome balancing of the circuit and without temperature compensation processes. According to the invention, in order to solve this problem, the ignition device is characterized by an auxiliary circuit, with an auxiliary winding magnetically coupled to the ignition coil, a capacitor and a diode, which is connected in parallel with the control section of the control component. The auxiliary winding charges the capacitor up via the diode, as long as the induction and therefore the voltage in the auxiliary winding are increasing. After exceeding the maximum voltage, this is maintained at the capacitor while the voltage in the auxiliary winding decreases. If the difference reaches the threshold voltage of the control component, in particular of a thyristor, this is switched on and blocks the switching transistor. Due to this circuit, the ignition timing is very close behind the timing of the greatest possible energy input into the primary coil.
