Patent ID: 8791626

Claim:
A spark plug comprising: an insulator having a first end, the insulator having a center axis; a center electrode coupled to the insulator and having a center electrode tip extending beyond the first end of the insulator; 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 discrete ground electrode tip disposed on the second portion of the ground electrode, wherein the ground electrode tip is spaced from the center electrode tip; and a ring member operatively connected to the center electrode proximate the center electrode tip, wherein the ring member includes a top annular surface that is disposed at an angle with respect to the center axis but is not perpendicular to the center axis; wherein the ring member has a diameter that is greater than a diameter of the center electrode after attachment to the center electrode such that the ring member extends beyond an outer periphery of the center electrode; wherein the ground electrode tip is spaced from an edge of the ring member to create a spark gap.
