ABSTRACT:
An improved spark plug for use in internal combustion engines is effective to produce a plurality of sequential sparks. The spark plug has a metal shell with an insulator member in the metal shell and extending therefrom, as is conventional. The improvement comprises a first electrode which extends from one end of the insulator member and has a free end spaced from a first end of a second or carrier electrode end portion. A first set of a spark discharging surface and a spark landing surface is formed on the free end of the first electrode and on the first end of the carrier electrode end portion respectively. A third electrode extends from the metal shell and has a free end spaced from a second end of the second or carrier electrode end portion. A second set of a spark discharging surface and a spark landing surface is formed on the second end of the second or carrier electrode end portion and on the free end of the third electrode respectively.
