Abstract
A multi-electrode spark plug having a large spark target volume is disclosed. The spark plugs have a plurality of ground electrode rods which extend from the base of the spark plug and are twisted around center electrode to provide a plurality of substantially equidistant spark points relative to the center electrode. The spark points are formed in parallel and around the elongated axis of the spark plug. This configuration enables the spark to be created where the localized concentration of fuel to air is richer, such as that which may exist when the engine is operating with lower revolutions per minute. Test results indicate that automobiles equipped with the multi-electrode spark plugs exhibit improved fuel economy, and substantially reduced emissions and air pollution.
