Abstract

Die Erfindung betrifft eine Glühkerze für Dieselmotoren, mit einem Gehäuse (1), einem Heizstab (3), der in dem Gehäuse (1) in axialer Richtung beweglich ist und aus dem Gehäuse (1) an einem vorderen Ende herausragt, und einer Druckmesseinrichtung (4, 6) zum Messen eines auf den Heizstab (3) einwirkenden Brennraumdrucks. Erfindungsgemäß ist vorgesehen, dass in einen Gehäuseinnenraum ein Stoff (7, 9) eingefüllt ist, der bei den im Betrieb auftretenden Temperaturen von flüssiger bis pastöser Konsistenz ist oder es wird und von dem Heizstab (3) erzeugte Wärme an das Gehäuse (1) leitet.
