Definitions

  • Glow pin candle with glow pin designed as a pressure sensor
  • Sensor-integrative concepts in which a pressure sensor is arranged on or in the glow plug, have the advantage over the previously known sensor concepts for measuring the pressure in the combustion chamber of a fuel engine that no additional borehole has to be provided in the fuel engine. This advantage increases all the more, since the space for attaching additional sensors is very limited in modern fuel engines.
  • the invention relates to a ceramic glow pencil candle 1, as shown in FIG. 1. It consists of a candle housing 2 and a ceramic glow pencil 3.
  • the ceramic glow pencil 3 has an electrically conductive layer 4 and an electrically insulating layer 5.
  • the insulating and the conductive ceramic is produced on the basis of organosilicon polymers which contain different proportions of one or more fillers, such as MoSi 2 , CrSi 2 , MoC 2 , graphite, Fe, Si, SiC, A1 2 0 3 .
  • a connecting pin 6 is additionally provided, which is connected to the glow plug.
  • a contact element 7 can be provided for this purpose, which is embedded in a sleeve 10 and is electrically insulated from the candle housing.

Abstract

L'invention concerne une bougie crayon de préchauffage pour moteur à combustion interne, qui comprend essentiellement un culot de bougie et un boulon d'assemblage disposé dans le culot de bougie, ainsi qu'un crayon de préchauffage pouvant être mis en contact avec le boulon d'assemblage. Ledit crayon d'assemblage (3) présente des propriétés électriques dépendant de la pression et peut s'utiliser comme capteur de pression. La déformation du crayon de préchauffage (3) sous l'effet de la pression peut être détectée par un dispositif de mesure (11).
