Abstract
Abstract A distributor for an internal combustion engine, especially of the type having a plurality of cylinders, each having a plurality of ignition plugs, has leads between discharge electrodes and cable connectors which are made of electrically-resistive material in order to attenuate electromagnetic noise generated during discharge. One type of " lead includes a flat, electrically-resistive conductor mounted on a flat insulator, and is especially effective in attenuating low- frequency noise. Another type employs a graphite fiber core as an electrically-resistive conductor, and is especially effective in attenuating high-frequency noise.
