(57) A radio-frequency-noise-suppressive ignition system for an automotive vehicle's engine,
comprising a plurality of spark plugs (1) each installed within a corresponding engine
cylinder having an elongated monolithic resistor (7) equal to or more than eight millimeter
long, noise suppressive resistance-contained high-tension cables (13), one of which
being connected between a secondary winding of an ignition coil (27) and distributor
(24), the others of which being connected between a plurality of fixed electrodes
(17) of the distributor (24) and respectuve spark plugs (1), the distributor (24)
having a rotor (22) electrically connected to a center electrode (16) via a contactor
(19) made of a high-resistance material which is connected to the secondary winding
of the ignition coil (27), the rotor (22) including a rotor electrode (21) having
a discharge gap (20) against each of the fixed electrodes (17) and a dielectric material
(25) preferably made of silicone glass secured to a portion of at least one of the
top and bottom surface areas of the rotor electrode (21), and a resistance material
(29) provided at an intermediate part of the rotor electrode (21) between one end
of the rotor electrode (21) which is connected to the contactor (19) and the portion
of the rotor electrode (21) to which the dielectric material (25) is secured.
