A REPORT OF SOME NEW DEVELOPMENTS IN RFI SUPPRESSION

The methods of radio frequency interference (RFI) suppression presently widely used in automobiles have operating problems when employed with capacity discharge or magnetic ignition systems in "off-the-road" types of equipment. Tests have shown that several new methods have been extremely effective with these two types of ignition systems and are compatible with satisfactory engine performance. A series of tests using several suppression devices on snowmobiles, power mowers, chainsaws, and a motorcycle is described. It is concluded that there is no reliable single way of suppressing all capacity discharge or magneto ignition systems. Although the varied electrical characteristics of the ignition system do not affect RFI suppression, the construction details of the engine and the geometry of the cable routing do.
