摘要
A spark plug (10) having an elongated ceramic insulator (12) includes numerous design features in various strategic locations. At least the ground electrode (26) is fitted with a rimmed, hemispherical metallic sparking tip (56) which controls rogue electrical arcing (62) and facilitates attachment techniques due to increased surface contact with the ground electrode (26). The various features of the spark plug (10) cooperate with one another so that the physical dimensions of the spark plug (10) can be reduced to meet current demands of newer engines without sacrificing mechanical strength or performance.
