摘要： An improved ignition apparatus for an internal combustion engine includes at least an ignition coil and a first electrode assembly and a second electrode assembly, each thereof including an electrode, and each of the electrodes of the first and second electrode assemblies is electrically connected to one end of a secondary winding of an ignition coil. The electrodes are supported on a cylinder head of the engine being electrically insulated therefrom and they form a spark gap for producing spark discharge therebetween, and a high tension circuit connecting the electrodes to the secondary winding of the ignition coil is electrically insulated from the body of the engine. The ignition apparatus having the above-described construction has the functional effects of improving the ignition performance, simplifying the withstant voltage design of constituent components, improving the antifouling performance at a spark gap portion and increasing the radio frequency interference suppression performance.

摘要： A spark plug and connector assembly having a spark gap formed from two electrodes which are both electrically isolated from ground. The spark plug includes an insulator mounted in a tubular metal shell having a threaded end for engaging a corresponding opening into a combustion chamber in an internal combustion engine. The two electrodes are mounted within separate parallel bores through the insulator. Each electrode has a tip projecting from the insulator for defining the spark gap. The electrodes also have terminal ends which are recessed within the insulator bores. The electrode terminal ends are centered within and spaced from the walls of the bores. Tubular connectors attached to the ends of two high-voltage ignition cables are received within the insulator bores and slide telescopically onto the electrode terminal ends. The connectors are also recessed within the insulator bores to prevent arcing therebetween. The wires pass through a resilient insulating boot which tightly engages an annular groove on the exterior surface of the insulator.

摘要： A multiple air gap spark plug is provided with an unobstructed air gap spark generating region between the primary electrodes. The high voltage or primary electrodes are arranged to be in confronting relation for spark generation with the intermediate or secondary electrodes arranged to be on either side of the straight line path between the high voltage electrodes. The resulting sparks generated in each air gap between adjacent electrodes will coalesce into a single spark kernel existing between the primary electrodes and laterally bounded by the secondary electrodes.
