Abstract: A ground electrode is provided having a ground electrode body, the ground electrode body having an anchored end and a non-anchored end opposite the anchored end. The ground electrode includes a plateau extending from a surface of the ground electrode body adjacent the non-anchored end. In illustrative embodiments, the plateau is formed by removing a portion of the ground electrode body near the non-anchored end. The plateau is configured to be exposed around its periphery. A noble metal tip is fixably attached to the plateau.

Abstract: An electrode for a spark plug includes an electrode tip end. A first weld affixes at least a portion of the noble metal tip to the tip end of the electrode. The noble metal tip has a fold around its periphery. A second weld joins the fold of the noble metal tip to the tip end of the electrode and creates a seal over the first weld.

Abstract: A spark plug includes an insulator having a first end, the insulator having a center axis and a center electrode coupled to the insulator and having a center electrode tip extending beyond the first end of the insulator. The spark plug further includes a ground electrode having an end spaced from an end of the center electrode, the ground electrode having a first portion extending substantially parallel to the center axis and a second portion extending at an angle from the first portion and relative to the center axis. A ground electrode tip is disposed on the second portion of the ground electrode, wherein the ground electrode tip is spaced from the center electrode tip. A ring member is operatively connected to the center electrode proximate the center electrode tip.

Abstract: A spark plug is provided that ensures that a ground electrode is positioned in a predefined, precise orientation when installed in a spark plug hole of an engine head. The spark plug is configured for axial insertion into the plug hole, and has a non-axisymmetric ground shield that fits into the plug hole, wherein the ground shield has an outer shield surface with a non-axisymmetric shape and the plug hole is also provided with a complementary non-axisymmetric shape. The spark plug includes a central insulator, which has an inner end surrounding a central electrode and supporting the ground shield, which is mounted on the insulator to support a ground strap adjacent the electrode for forming a spark therebetween. The insulator and ground shield are axially slidable into the plug hole, and the spark plug includes a jamb nut which is rotatable to fix the spark plug in position in a predefined orientation. Preferably, an outer surface of the insulator and an inner surface of the ground shield have complementary shapes wherein the ground shield fits closely on the insulator. For example, the outer insulator surface and the inner shield surface may have a complementary axisymmetric shape, such as cylindrical, or a non-axisymmetric shape, which may conform to the non-axisymmetric shape of the outer shield surface.

Abstract: A system for testing an insulative material for a spark plug comprises a test spark plug having at least a center electrode and an insulator comprised of an insulative material surrounding at least a portion of the center electrode, wherein the insulator has an end that is closed, whereby the closed end of the insulator encloses an end of the center electrode. The system may further include a test engine that simulates engine conditions, wherein a conventional spark plug is installed in a first ignition port of the test engine and the test spark plug is installed in a second ignition portion of the test engine and a control system for controlling ignition signals to the test spark plug and the conventional spark plug.
