ABSTRACT:
A high tension generating and distributing device includes a plurality of secondary windings 11, 12, connected to associated ones of the spark plugs of an internal combustion engine, these secondary windings being mounted on a single magnetic frame 1, 2 offering a plurality of flux paths through a low tension primary winding 7 or 8, each of these flux paths being associated with one of the secondary windings 11, 12 and with means, for example in the form of flux gaps 3, 4, 5, 6 or auxiliary windings 213, 214 having associated therewith shunt switches 215, 216, for limiting or cancelling the magnetic flux in some of the flux paths so as to leave one flux path with a higher rate of change of flux than the attenuated rate of change of flux in the other flux paths, thereby selecting the secondary winding associated with the non-attenuated flux path as the one in which the high tension current is to flow. Each secondary winding may be associated with one or more sparking plugs, in which latter case the plugs appropriate to the one secondary winding will be in cylinders whose timing is directly opposed in a four-stroke cycle.
