Abstract:
    The utility model provides a multi-pole sparking plug comprising a housing which is provided with porcelain core and a lateral electrode. The optional position between the center and the edge of the porcelain core is provided with a center electrode, and the position between the center electrode and the lateral electrode, the circle in the middle part of the center electrode is orderly provided with several transition electrodes arranged in circle arc shape, and the said space between the central electrode and the electrode is larger than that between other electrodes. When it removes the central electrode to optional position between the porcelain core center and the edge, the transition electrode between the central electrode and the lateral electrode is arranged in circle arc shape, and each electrode has a long diameter, a good interval insulation and a long service life, so it can realize the advantages of that multi-flashover, sufficient combustion, saving energy and decreasing pollution.
