ABSTRACT:
A pulse transformer produces sufficient energy at its secondary winding to initiate arcing of a spark gap in response to the interruption of current flow to its primary winding. Upon initial arcing of the spark gap, a charged capacitor is coupled across the gap thereby extending arcing duration beyond that produced by the coil. The total spark energy is determined by the value of the capacitor and the voltage to which it is charged.
The invention is adaptable to provide spark energy to each cyclinder of a multicylinder engine without the need for a distributor.
