313110500 | Spark plug type | 8 |
20100007257 | Spark Plug - A spark plug for an internal combustion engine has a housing and an insulator held in a clamping area of the housing, which electrically insulates a central electrode from the housing, a heat transfer area having a circumferential gap between the housing and the insulator being provided in the area of a combustion chamber-side end section of the housing for dissipating the heat absorbed by the insulator. The heat transfer area and the clamping area are spatially separated from each other. | 01-14-2010 |

20110050069 | SPARK PLUG - A spark plug includes a terminal for receiving an electrical charge, a firing electrode on a firing end of the spark plug, and a conductor electrically coupling the terminal and the firing electrode. The spark plug further includes a casing, an electrical insulator, and a ground electrode. The casing is at least partially formed from an electrically conductive material and is configured to be electrically coupled to a ground. The electrical insulator separates the conductor from the casing. The ground electrode is positioned proximate to the firing electrode, but separated from the firing electrode to allow a spark to jump between the firing and ground electrodes during operation of the spark plug. The ground electrode includes an extension coupled to the casing and projecting from the casing such that the firing electrode is closer to the ground electrode than the firing electrode is to the casing. There is substantially no air gap between the interior of the casing and the electrical insulator from the firing end of the spark plug. | 03-03-2011 |

20130229102 | SPARK PLUG - A spark plug includes a terminal for receiving an electrical charge, a firing electrode on a firing end of the spark plug, and a conductor electrically coupling the terminal and firing electrode. The spark plug further includes a casing, an electrical insulator, and a ground electrode. The casing is at least partially formed from an electrically conductive material and is configured to be electrically coupled to a ground. The electrical insulator separates the conductor from the casing. The ground electrode is positioned proximate to the firing electrode, but separated from the firing electrode by a spark gap. The ground electrode includes an extension projecting from the casing such that the firing electrode is closer to the ground electrode than the firing electrode is to the casing. There is substantially no air gap between the interior of the casing and the electrical insulator from the firing end of the spark plug. | 09-05-2013 |
20140368105 | SPARK PLUG - A spark plug has a metal shell and a ground electrode joined at a base end portion thereof to the metal shell and includes a surface layer and a core higher in thermal conductivity than the surface layer. The surface layer has a thickness of 0.2 to 0.4 mm at a specific position that is located 1 mm from the base end portion. The spark plug satisfies the following condition: W1≧W2×1.55−(W3+0.25) where W1 (mm) is a width of the metal shell at a weld region of the metal shell joined with the base end portion in a specific direction that extends perpendicular to the axis direction through a center line of the ground electrode; W2 (mm) is a thickness of the ground electrode at the specific position in the specific direction; and W3 (mm) is a thickness of the surface layer at the specific position in the specific direction. | 12-18-2014 |
