A cambered shape of an external negative electrode (11) of an internal combustion engine's spark plug so that a spark bridging the plug's spark gap (17) impinges first at the base region (14) and travels outward and around to initiate burn of almost 100% of available fuel. The cambered shape culminates with an end section (16) that is +E,fra 1/4+EE of a sphere and has symmetry to the radial edge of a center electrode (13).
