Abstract
A multipoint spark ignition system for an internal combustion engine. The head of each cylinder of the engine is provided with at least three openings, the axes of which intersect within the cylinder. A spark plug is threaded within each opening, and each spark plug includes a single electrode. The inner end of each electrode carries a thin metallic, laterally extending disc, and the peripheral edges of the discs are spaced apart to provide spark gaps. A first spark plug of the series is connected to the ignition coil of the engine, while the electrode of the last spark plug in the series is connected to ground and the electrodes of the intermediate spark plugs are capacitively loaded.
