Die Regelwendel besteht hierbei aus einem Material, das einen positiven oder einen negativen Temperaturkoeffizienten des Widerstands aufweist, so daß hierdurch eine Selbstregelung des Glühstromes für das Heizelement erfolgt, wodurch das Überhitzen des Heizelements vermieden werden soll.In the known glow plugs there are heating and measuring filaments arranged in series, one behind the other usually the heating coil in the front area of the glow plug is arranged, which with a control coil Inner pole of the glow plug is connected.
