20090096344 | Sparkplugs and method to manufacture and assemble - The invention is a spark plug having multiple precise spark gaps (G} with a donut shaped electrode ( | 04-16-2009 |
20100072874 | SPARK PLUG - A spark plug includes a ceramic insulator sleeved on a center electrode so that an end of the center electrode extends outwardly of an end surface of the ceramic insulator, a conductive outer shell surrounding spacedly the ceramic insulator, and a ground electrode including an annular portion disposed coaxially around the end of the center electrode such that an annular gap smaller than 1 mm is defined between the annular portion and the ceramic insulator, and a connecting portion interconnecting electrically the annular portion and the conductive shell. The annular portion of the ground electrode cooperates with the end of the center electrode and the end surface of the ceramic insulator to define an air-blocking space thereamong in spatial communication with the annular gap. | 03-25-2010 |
20120104926 | SPARK PLUG, PARTICULARLY FOR A STATIONARY INTERNAL COMBUSTION ENGINE - A spark plug, especially for a stationary internal combustion engine, is described that includes a ground electrode and a center electrode, the center electrode including an inner area, an outer ring and at least two crosspieces, in which the at least two crosspieces connect the inner area to the outer ring. | 05-03-2012 |
20130193833 | SPARK PLUG - 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. | 08-01-2013 |
