Abstract

Spark plug for an internal combustion engine having a metal shell (20) enclosing a ceramic insulator (16) containing a conductive centre electrode (18) having a bottom end (58) exiting from the insulator. The bottom end of the centre electrode is spaced apart from a groud electrode ( 12) attached to the metal shell by at least one support member or mounting post (38) . The ground electrode is ring/openring shaped and its interior diameter ranges from equal to the exterior diameter of the centre electrode to a multiple of the size of the interior diameter of the centre electrode.
