摘要： Spark plug for an internal combustion engine, having a center electrode and a ground electrode. A spark gap is formed between the center electrode and ground electrode for igniting a fuel mixture by an electric ignition spark developing between the center electrode and the ground electrode. The center electrode and the ground electrode are contoured such that a ratio of a surface of the center electrode and the ground electrode, which is available for development of the ignition spark to a wear volume when an ignition spark is generated, is increased in such a way that an enlargement of the spark gap occurring as a result of wear when an ignition spark is generated is minimized.

摘要： A spark plug includes a center electrode extending in an axial direction; an insulator formed externally of the outer circumference of the center electrode; a metallic shell formed externally of the outer circumference of the insulator and having a ledge which supports the insulator; and a ground electrode joined to the metallic shell. The insulator has a support portion which faces the ledge. A “frontward direction” is defined as the direction parallel to the axial direction toward a spark portion formed between the center electrode and the ground electrode. The insulator has a diameter reduction portion whose outside diameter reduces along the frontward direction from the support portion, and a diameter increase portion whose outside diameter increases along the frontward direction from the front end of the diameter reduction portion. This restrains the generation of leak current while maintaining heat resistance of the spark plug.

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.
