AbstractThis system provides means for storing electrical energy in a plurality of inductors during the period when no demand for the stored energy is made and having means for discharging the stored energy from each particular inductor to fire a particular igniter or spark plug, one igniter at a time. Circuits include individual inductors for each igniter, wherein the primaries are connected to the charging means and the secondaries of the inductors to the discharging means in order to provide the requisite energy needed to fire the igniters substantially instantaneously on demand. Circuits providing double energy storage inductors and capacitors also utilize a standard distributor having a minor modification. These circuits do not require the usual break points in the primary windings although the system may be battery energized. The conventional break point single transformer system has been modified using double energy techniques to very substantially increase its energy output as delivered to the igniters.
