Definitions

  • the invention relates to a spark plug with a spark plug body with body electrode, one arranged in the spark plug body Insulator with insulator bore and a center electrode, which is arranged in the insulator bore.
  • catalytic noble metal coating lowers the Rußabbrandtemperatur and prevents thereby shunts by RußAuth für the center electrode and the insulator foot. This will be done in detail ensures that the catalytic coating the soot oxidation accelerated even at low temperatures.
  • the noble metal coating By applying the noble metal coating, the oxidation promoted, so that the soot particles at low temperatures oxidize.
  • the soot particles then lose their Stop on the coated insulator surface, leaving itself can not form an electrically conductive layer and a contact between the high voltage conducting center electrode and a such electrically conductive layer on the insulator ceramic is prevented.
  • the noble metal coating is platinum, Palladium or rhodium.
  • spark plug according to the invention are the subject of the claims 2 and 3.
  • the single figure shows the combustion chamber side of the Embodiment of the spark plug according to the invention in a Sectional view.
  • a spark plug usually a spark plug body 2 with body electrode 4, a arranged in the spark plug body 2 insulator 3 with insulator bore and insulator foot 3.1 and a center electrode 1, which is arranged in the insulator bore of the insulator 3. Between the insulator and the spark plug body 2 is a Respiratory space 5 is provided.
  • the catalytic coating 3.2 is preferably on the inner surface of the insulator bore provided, the center electrode 1 faces.
  • the catalytic coating consists in particular of a precious metal and preferably platinum, palladium or Rhodium.
