<p>A spark plug comprising a first electrode (4) to which a high potential is to be applied when a spark is to be generated and a second electrode (6) to be connected to ground. An intermediate insulated electrode (5) is positioned between the first (4) and second (6) electrodes such that when a high potential is applied to the first electrode (4) two sparks are formed, one between the first electrode (4) and the intermediate electrode (5) and the other between the second electrode (6) and the intermediate electrode (5).</p> |
