ABSTRACT:
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.
