For an ignition system including an an ignition coil (40), a distributor (10) and spark plugs (70), several measures are taken to suppress radio frequency interference radiation therefrom. The distributor (10) has a rotor segment (24) with its output tip surface (24a) formed of of conductive and dielectric materials (26, 28) separately disposed from each other. Each of the spark plugs (70) includes a monolithic resistor (80) connected between its input terminal (82) and its center electrode (74). The spark plugs are connected to the distributor through respective first cables (60) each including a carbon impregnated conductive wire (92) covered with an insulating sheath (94). The ignition coil (40) is connected to the distributor (10) through a second cable (50) including a carbon impregnated conductive wire covered with an insulating sheath. The second cable carbon impregnated conductive wire has a resistance of 12 k OMEGA or more. |
