Abstract
A spark plug having a shell with a ground electrode recess. A ground electrode having an insertion end, a firing end, and a round cross-sectional profile toward the insertion end is inserted into the ground electrode recess of the shell. An attachment portion surrounds at least a portion of the ground electrode and includes a solidified bonding material at a connection interface between the ground electrode and the shell. In some implementations, the ground electrode can have a copper core that extends further into the shell, past the distal end of the insulator. In some embodiments, the ground electrode has a sheath surrounding the copper core that has aluminum and a high weight percentage of nickel.
