Abstract

See full text

An ignition cable which applies ignition current from a power source to a spark plug of a spark ignited internal combustion engine while attenuating radio frequency currents. An inner elongated electrically conductive metallic core made of a high permeability material has an electrically semiconductive layer disposed thereabout and in intimate contact therewith. Insulation surrounds the semiconductive layer. Direct current is effectively and preferentially conducted by the inner core to provide ignition current, while high frequency currents are crowded by the skin effect into the semiconductive layer, where they are damped by the resistance thereof.
