ABSTRACT:
The invention is a spark plug having multiple precise spark gaps (G} with a donut shaped electrode (20) attached to the firing end of the central electrode (32), as well as a cylindrical ground sleeve (40) that is pressed on to the primary shell (36) of the spark plug. The electrode donut (20) is generally flat and laded out in a radial direction towards the ground prongs (42) that protrude up towards the firing end from the ground sleeve (40). In conjunction with their structure, allow for the generation of a spark from every single ground prong (42) on the ground sleeve (40). This is spark potential area (G). Such multiple spark potential area along with the electrode donut (20) and ground sleeve (40) relation provides a more rapid and complete combustion of the air-fuel mixture within the internal combustion engine, which, in turn, results in more torque and more horse power.
