Abstract
To improve the noise suppression characteristics of an ignition system for an Otto-type internal combustion engine, radio noise suppression resistors (8, 18, 22) are molded into the distributor cap (25) and electrically connected, respectively, between the tower cable connectors (19, 21, 23) on the distributor cap and the respective distributor cap terminals, which may be the peripheral terminals (16, 17) or the center wiping or sliding terminal (9) for the distributor rotor. The distributor rotor then can have a single highly conductive electrical element as a center electrode, leading to the outside peripheral rotating distributor electrode (14), which is spaced from the fixed gap electrodes by a spacing of between 0.5 to 3 mm, preferably at least 2 mm. Preferred values for the noise suppression resistors are between 1 to 5 kilo ohms.
