  • Spark plug
    Patent number: 3967149
    Abstract: This invention relates to spark plugs for internal combustion engines and is particularly directed to a center electrode having a sparking tip composed of a precious metal and to the method of making the same. The known advantage of the use of a precious metal electrode is that considerably greater spark plug life is achieved. The invention achieves the advantage while greatly reducing the mass of precious metal employed. A further feature of the invention is the co-planar disposition of the end of the center electrode and its supporting insulator.
