摘要: An ignition plug suitable for igniting meager fuel vapor/air mixtures has a tubular metal housing, an insulating body which is divided into longitudinal portions and contains a connection pin and a middle electrode positioned in its through borehole. A longitudinal portion of the insulating body, which longitudinal portion is enclosed by the metal housing, consists of dielectric material and, together with the metal housing and the connection pin, forms a capacitor which has a capacity of 120 to 500 pF, chiefly 200 to 400 pF. In order to connect electrial flashovers between the connection pin and the metal housing in the areas of the separating surfaces of the insulating body annular electrical insulating elements are arranged between the separating surfaces which are made of the material elastic at all temperatures of the ignition plug.
