Neutral electrode spark plug
摘要:
A neutral electrode spark plug (10) consisting of a cylindrical metallic shell (20) having a tubular ceramic insulator (22), including an insulator tip (28) enclosed therein, and a central electrode (30) surrounded by the ceramic insulator (22). The central electrode (30) has a firing tip (36) extending from the insulator tip (28). A neutral electrode (38) extends from the insulator tip (28) providing a first spark gap that is separated from the central electrode (30). A side ground electrode (40) is attached to the metallic shell (20) and is laterally aligned with the central electrode (30) and the neutral electrode (38). The ground electrode (40) provides a second spark gap that is separated from the neutral insulator (38) and a third spark gap formed with the ground electrode (40) a distance away from the insulator tip.
