摘要

Improved spark plugs, based on low voltage effluvia, for combustion engines characterized by comprising an inner electrode that is, compared to the outside, very thin, and these electrodes are separated from each other, by an insulating material, entering the part of the electrode that leaves the body of the spark plug in the combustion chamber of the engine; the surface of the electrode protruding from the body of the spark plug is almost completely covered with the outer electrode.
