Abstract
An ignition distributor for an internal combustion engine is provided with a novel rotor electrode which substantially reduces radio frequency interference generated by spark discharges across the rotor gap. At least the tip segment of the rotor electrode is formed of a composite material consisting of a first phase of fibers of a dielectric material interspersed with a second phase of a conductive material. In operation, dielectric fibers protrude from the conductive phase into the gap promoting ionization therein so that electrical discharge occurs at voltages where radio frequency signal production is substantially suppressed.
