ABSTRACT:
A spark plug for internal combustion engines having a center electrode, a ceramic insulator body and metal sleeve around the body. The sleeve defines an annular outside electrode around the center electrode with a concave depression in the insulator between the electrodes. The plug is operated at high current and voltage so that a high intensity spark will burn off any combustion residue on the relatively small insulator area between the electrodes. A process for removing combustion residues using this spark plug is also disclosed.
