  • the resistance package in the resistance melting the connection side facing away from the combustion chamber has a larger cross section than the resistance package on the side facing the combustion chamber. This has the advantage that despite the spatial limitation and the use of a relatively small resistance package in the area of the electrodes, there is a high degree of stability with regard to the capacitive loads.
  • the figure shows the combustion chamber end of the spark plug according to the invention with a resistor package.
  • the figure shows schematically the section of a spark plug on the combustion chamber side in a sectional illustration.
  • an insulator 11 is arranged in a metallic tubular housing 10, the rotationally symmetrical axes of the housing 10 and the insulator 11 being congruent.
  • the insulator 11 there is also a contact pin 12,
  • Burn-off resistor 13 which is embedded in a conductive contact panate 14, a contact pin 15 and the center electrode 16 are arranged.
  • the bore of the insulator 11, which receives the entire conductive center arrangement is designed in such a way that that the insulator bore 17 areas of different diameters on. These different diameters are designed such that the diameter of the insulator bore 17 is greatest in the region of the contact bolt, while the diameter of the insulator bore is smallest on the combustion chamber side.
  • the resistance package 13 thus also has a larger cross section on the side of the contact bolt 12 than on the electrode side.
  • the foot hole is made with a diameter of about 3 mm, while the
  • Hole on the side of the contact pin has a diameter of approximately 4.6 mm.
  • the conductive contact panate in which the erosion resistor 13 is fused must have a smaller diameter in the front region.
  • the smaller diameter increases the energy density in the resistance package.
  • the resistance package 13 has a larger diameter in the area facing away from the combustion chamber.

Abstract

L'invention concerne une bougie comprenant un boîtier métallique tubulaire qui renferme un isolateur, lequel contient à son tour un élément conducteur interne en forme de bâtonnet. L'élément conducteur interne est constitué d'un boulon de contact, d'une résistance limitatrice de courant enrobée dans une matière de contact électriquement conducteur, d'une broche de contact et d'une électrode centrale. La résistance limitatrice de courant présente deux zones de diamètres différents. Dans la zone côté chambre d'explosion, le diamètre est plus petit que dans la zone opposée à la chambre d'explosion.
