Abstract
A spark plug generally similar to standard design including a body member supporting a pair of electrodes to provide a spark gap in the combustion chamber of an internal combustion engine, the side electrode carrying a projecting extension outside the spark gap but still within the flame ignition and combustion zone of the engine so as to provide a reaction member which enhances the action of catalytic agents in the fuel or alternatively incorporated in the reaction member, itself.
