Definitions
- a contact surface seen in cross-section is preferably wider than a contact surface opposite the contact surface.
- the spacer means is expedient with its bearing surface on the ground electrode and with its contact surface at the firing end. In order to prevent the center electrode from sliding off the spacer means by vibrations, the contact surface is wider in cross section than the firing end. For a slipping of the spacer means is advantageously prevented.
- FIG. 1 shows a spark plug 1 with a housing 2, a center electrode 3 and an insulator 4 surrounding the center electrode 3.
- the housing 2 is assigned at least one ground electrode 6. Between a firing end 7 of the center electrode 3 and the ground electrode 6, a spark gap 8 is formed.
- the spark plug 1 acts in the preferred embodiment as a Gleitfunkenkerze.
- spark plug 1 is advantageously achieved that the spark gap 8 remains unchanged during the entire life of the spark plug 1, wherein even after a mileage of a motor vehicle engine of about 200,000 km, the electric power delivery is unchanged.
