Abstract

Die Erfindung bezieht sich auf eine Glühstiftkerze für eine Brennstoffkraftmaschine, bestehend im Wesentlichen aus einem Kerzengehäuse und einem in dem Kerzengehäuse angeordneten Anschlussbolzen, der über Kontaktelemente mit einem keramischen Glühstift elektrisch verbunden ist, wobei die Kontaktelemente (7a, 7b) zumindest ein elastisches Verformungsverhalten aufweisen und als Drucksensor verwendbar sind, wobei die Verformung der Kontaktelemente (7a, 7b) durch Druck durch eine Messeinrichtung (11) detektierbar ist.The invention relates to a glow plug for a fuel engine, consisting essentially of a plug housing and arranged in the plug housing terminal bolt, which is electrically connected via contact elements with a ceramic glow plug, wherein the contact elements (7a, 7b) have at least one elastic deformation behavior and can be used as a pressure sensor, wherein the deformation of the contact elements (7a, 7b) by pressure through a measuring device (11) is detectable.
