Composite ceramic electrode and ignition device therewith |
摘要 |
A spark plug, center electrode and method of construction is provided. The spark plug has a generally annular ceramic insulator and a conductive shell surrounding at least a portion of the ceramic insulator. A ground electrode is operatively attached to the shell, with the ground electrode having a ground electrode sparking surface. A center electrode has an elongate body with a center electrode sparking surface. The center electrode sparking surface and the ground electrode sparking surface provide a spark gap. The center electrode body is constructed of a composite material including at least one ceramic material.
