SPARK PLUG ELECTRODE AND METHOD OF MANUFACTURE |
摘要 |
A spark plug for an internal combustion engine includes a housing having a distal end, a proximal end, and an outer periphery extending therebetween. A mounting thread formed on the outer periphery at the proximal end of the housing secures the spark plug to the engine. A center electrode fixedly secured along a central axis of the housing has a first end extending outwardly from the proximal end of the housing. A ground electrode secured to the proximal end of the housing has an electrode tip at a first distance from the center electrode. The electrode tip has a central aperture extending through the ground electrode from an upper surface to a lower surface. A protruding edge circumscribes the aperture and extends a second distance from the upper surface of the electrode tip towards the center electrode.
