<p>An improved anti-fouling controlled erosion long life spark plug (36) for high current spark discharges with low heat absorbing large circular gap (31) electrode structure comprised of a disc section center electrode (23) and low mass ring ground electrode (21) supported by three legs (24) defining flow-through slots (25) behind the ring which extends into the combustion chamber and an insulator end (13a) recessed with respect to the flow-through slots to prevent its fouling, the plug end electrode structure minimizing flow obstruction, flame quenching, and heat absorption from the combusting air-fuel mixture.</p> |
