Patent number: 8994256Abstract: An igniter for an internal combustion engine includes a center electrode, an insulator disposed about the center electrode, and a ground shield or a threaded portion disposed about the insulator, wherein the insulator includes a tip portion extending past an end portion of the ground shield and a tip portion of the center electrode extending through and away from the tip portion of the insulator. The igniter further includes a cap secured to the center electrode, wherein the cap extends past and covers a distal end of the tip portion of the center electrode and a distal end of the tip portion of the insulator. A spark gap is disposed between a peripheral edge of the cap and the end portion of the ground shield or threaded portion wherein the peripheral edge of the cap is spaced away from a surface of the tip portion of the insulator.Type: GrantFiled: July 5, 2012Date of Patent: March 31, 2015Assignee: Fram Group IP LLCInventors: Matthew Brian Below, Jeff Boehler, Corey Eiden

Patent number: 8970096Abstract: Disclosed herein is a spark plug comprising an insulative sleeve having a central axial bore and an exterior surface and a center electrode extending through the central axial bore of the insulative sleeve. The insulating sleeve is positioned within, and secured to, a metal shell that serves as a mounting platform and interface to an internal combustion engine. The metal sleeve also supports a ground electrode that is positioned in a spaced relationship relative to the center electrode so as to generate a spark gap. The insulating sleeve includes a shaped tip portion that resides in a recessed end portion of the metal shell. A coating is disposed on the exterior surface of the shaped tip portion of the insulative sleeve. The coating comprises a metal oxide, a noble metal, late transition metal, or a combination comprising two or more of the foregoing metals.Type: GrantFiled: December 6, 2011Date of Patent: March 3, 2015Assignee: Fram Group IP LLCInventors: Peter Unger, Ron Rohrbach, Jeff Boehler, Jing Zheng
