A sparkplug exhibiting very low resistance and inductance and having multiple side discharge negative electrodes and employing an integral capacitor extending from the plug body to the area of the connector to the ignition system to effectively absorb the electrical energy normally lost during the rise time of the ignition transformer, to store such electrical energy, and to discharge the stored energy across the electrode gap during the first few nanoseconds of the spark event. The sparkplug body is comprised of iron or steel so as to be threaded into a conventional sparkplug hole. The body has a cylindrical extension which serves as the negative plate of the capacitive element. A positive electrode forms the interior portion of the sparkplug. One end of the positive electrode forms a spark channel with two or more negative electrodes in a plane perpendicular to the motion of the piston. The other end of the positive electrode connects by means of a resistive element to a high-voltage ignition cable of conventional design. The positive electrode also serves as the positive plate of the capacitive element and is cylindrical, extending centrally through the body and within the negative plate of the capacitive element. A moldable dielectric material completely fills the space between the positiveand negative plates of the capacitive element for the length of the sparkplug, and may also serve as the outer insulator of the spark plug if desired. An alternative embodiment offering two sets of opposing capacitive plates is also described.
