Zusammenfassung:PCT No. PCT/CZ95/00028 Sec. 371 Date Oct. 22, 1996 Sec. 102(e) Date Oct. 22, 1996 PCT Filed Dec. 6, 1995 PCT Pub. No. WO96/20523 PCT Pub. Date Jul. 4, 1996A spark plug with improved wear resistance includes an outer conductive housing, a ceramic insulator positioned within the housing, and a central electrode inside the insulator. One or more ring-shaped auxiliary electrodes are positioned on the ceramic insulator between the central electrode and the outer conductive housing. The one or more ring-shaped auxiliary electrodes have a central portion and peripheral edges which are thickened with respect to the central portion. The spark plug provides a spark gap between the central electrode and the auxiliary electrode and between the auxiliary electrode and the conductive housing.
