  • Patent number: 11158997
    Abstract: A spark plug for use with an engine block/cylinder head having a threaded bore and also for use with a spark plug wrench and an ignition wire. Also, an improved method for constructing a spark plug, the spark plug including a metal shell having a hex nut, a seat, a flange, a bore and threads. A ground electrode is associated with the shell and an insulator assembly occupies the bore and is gripped by the flange. The method includes the steps of forming the hex nut and the seat by carrying out operations on a blank, roiling the threads, fitting the insulator assembly into the bore, deforming the flange to capture the insulator, and forming the negative electrode by machining the blank.

  • Patent number: 9478946
    Abstract: A spark plug is disclosed and includes a metal tube which interiorly defines an axis and is externally-threaded for engagement with an engine block. An insulating has a portion which is disposed inside the tube and extends therebeyond. A positive electrode extends through the insulator and projects beyond the extending portion of the insulator. An annular ground electrode is coupled to the tube. The electrodes are configured such that a spark gap defined therebetween has an elongate channel which opens axially and away from the insulator and is substantially unobstructed in the axial direction. The ground defines a void having a central portion occupied by the positive electrode in use, an annular channel surrounding the central portion, and a plurality of lobes, each being positioned with respect to the central portion in a manner analogous to the placement of the planet gears with respect to the sun gear in a planetary gear arrangement.

  • Patent number: 9300116
    Abstract: The plug comprises a nut, a coupling extending from the nut and adapted to receive an ignition wire and an insulator extending from the nut and away from the coupling. A positive electrode extends through the insulator. An externally-threaded tubular portion extends from the nut in surrounding relation to the insulator and terminating, short of the insulator end, in a cap that is disposed in spaced relation to the insulator. The cap defines a void having: a central portion into which the positive electrode extends; an annular channel surrounding the central portion; and a plurality of lobes, each positioned with respect to the central portion as the planet gears are positioned with respect to the sun gear in a planetary gear. The cap has a central surface that is axially spaced from the insulator and a convex surface that surrounds and extends to the central surface.

  • Patent number: 9112334
    Abstract: A spark plug is disclosed and comprises: a metal tube which interiorly defines an axis and is externally-threaded for engine block engagement; an insulator having a portion which is disposed inside the tube and extends therebeyond; a positive electrode extending through the insulator and projecting beyond the extending portion of the insulator; and an annular ground electrode coupled to the tube. The electrodes are configured such that a spark gap defined therebetween comprises an elongate channel which opens axially and away from said insulator and is substantially unobstructed in the axial direction. The ground defines a void having: a central portion occupied by the positive electrode in use; an annular channel surrounding the central portion; and a plurality of lobes, each being positioned with respect to the central portion in a manner analogous to the placement of the planet gears with respect to the sun gear in a planetary gear.
