Abstract (en)
[origin: EP0505696A2] Ignition electrodes which are subjected to atmospheres containing soot are equipped with an insulator (20, 16) which can be heated. In order to regulate the heating power, a method is proposed in which the temperature on the heating winding (20) is measured at regular intervals by means of resistance-temperature-measuring methods (28), and the voltage supply to the winding is regulated in a corresponding manner. <IMAGE>
