(under subclass 118) Subject matter having a plurality of spark gaps connected in series.
(1) Note. The plural gaps may be located on the interior portion of the plug (e.g., used to ignite the combustible gas) or one or more of the gaps may be located in or on some other portion of the spark plug.
(2) Note. Spark gaps in series with the igniter spark gap, when not exposed to the cylinder charge, are often referred to as intensifier gaps, since they prevent voltage break-down until a voltage level, higher than would otherwise be required, is reached.
