Estimating the term…
An ignition plug of this invention is characterized in that a ground electrode thereof has a recess that faces the side surface of a single center electrode; more particularly, in the case of an L-shaped ground electrode whose free end is opposed to the center electrode with a spark gas in between, the recess is provided to on the free end of the ground electrode so that it can hold plentiful gas mixture to ignite near the spark gap by increasing its capacity with the increase of distance from the side surface of the center electrode; thus, the farther the igntion proceeds into the recess, the more intensively gas mixture is ignited, whereby instantaneous combustion can be caused in the entire space of a combustion chamber.
An ignition plug for use in internal combustion engines, in which at least one ground electrode is paired with a center electrode, said ground electrode is inwardly bent in the middle approximately at right angles toward said center electrode so that the end thereof may face the side surface of said center electrode with a spark gap in between, and the top of said center electrode is opposed to a piston with a space in between, characterized in that the end of said ground electrode is partially indented in such a way that there may form a recess for holding gas mixture there and the capacity of said recess may steplessly increase with the increase of the distance between said recess and said center electrode.
