Summary:

Emission control requirements have prompted optimization studies of many engine parameters, such as engine geometry, fuel preparation, and ignition. This paper describes an experimental ignition system which permits these studies with a spark that has an adjustable power level and independent programmable arc duration.This new ignition system uses inductive-discharge to strike the arc and, together with transformer action, sustains the arc from a single coil for any duration. Its principal features are: (1) programmable arc duration, (2) high arc current for full arc period, (3) fast voltage rise, (4) low average battery current drain, (5) no intermediate power supply, and (6) since it uses inductive storage, it can be integrated into present electronic systems if the need is proven. Limited test results are presented to show the effect of arc duration on engine operation
