  • Spark plug
    Patent number: 4029986
    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.
    Type: Grant

  • Spark plug
    Patent number: 4023058
    Abstract: An improved spark plug for use in internal combustion engines includes a center or first electrode positioned within a spark plug insulator member in a metal shell. An outer or second electrode extends from the metal shell and has a free end portion thereof spaced from a free end portion of the center electrode. An annular spark discharging surface is formed on said free end portion of the center electrode and an annular spark landing surface is formed on said free end portion of the outer electrode with the discharging and landing surfaces being in opposed or facing relation and cooperating to provide a spark in the form of a hollow column. A port is provided in the second electrode and is surrounded by the spark landing surface so that fuel on the opposite side of the outer electrode will be ignited.

  • Spark plug having electrodes shaped to produce a hollow spark column
    Patent number: 4015160
    Abstract: An improved spark plug for use in internal combustion engines includes a center electrode positioned within the spark plug insulator member in a metal shell. The other electrode extends from the metal shell and has one end portion thereof spaced from one end portion of the center electrode. An annular spark discharging surface is formed on one end of the center electrode and an annular spark landing surface is formed on one end of the outer electrode with the discharging and landing surfaces being in opposed or facing relation and cooperating to provide a spark in the form of a hollow column.
