摘要： A spark plug center wire assembly that includes a noise suppressing conductive seal with improved isolation of the seal from the heat generated at the firing end of the spark plug. The center wire assembly includes a firing electrode, a conductive glass seal, an intermediate electrode, the noise suppressing glass seal, and a terminal electrode. By locating the firing electrode, conductive seal and intermediate electrode between the noise suppressing seal and the spark gap, the center wire assembly is able to utilize the noise suppression attributes of the suppressive seal, while distancing the seal from the high temperatures created during the combustion process. A method of manufacturing the same is also disclosed in which the two glass seals are formed by sequential firing operations.

摘要： A spark plug and method of construction thereof is provided. The spark plug includes a metal shell having a through cavity, a lower insulator and a plastic upper insulator. The lower insulator is received in the through cavity and has a through passage with a center electrode received therein. A ground electrode is operatively attached to the shell in spaced relation from the ground electrode to provide a spark gap. The plastic upper insulator has a distal end received in the through cavity of the shell and a terminal end extending axially outwardly from the shell. The upper insulator has a through passage extending between the terminal end and the distal end. An elongate conductive member is received in the through passage of the upper insulator and is configured for electrical communication with the center electrode.

摘要： A spark ignition device, ground electrode therefor, and methods of construction thereof are provided. The spark ignition device includes a generally annular ceramic insulator with a metal shell surrounding at least a portion of the ceramic insulator. A center electrode is received at least in part in the ceramic insulator and a ground electrode extends from the shell to a free end portion. A firing tip is attached adjacent the free end portion of the ground electrode to provide a spark gap between the center electrode and the firing tip. The free end portion is at least partially bounded by at least one “as laser cut” peripheral side extending adjacent the firing tip.
