Abstract: A combustion initiation system includes an initiating device for producing, containing and propelling a combustion initiating plasma having an energy density approaching that produced by combustion of the fuel itself, and is suitable for initiating combustion in relatively lean mixtures of various types of fuels. A high voltage power supply delivers electrical energy by a coaxial cable to the initiating device which communicates with a fuel mixture in a combustion area such as the combustion chamber of an ordinary internal combustion engine. The initiating device includes a capacitive portion for storing a large quantity of electrical energy therein derived from the power supply, and an electrode portion integral with the capacitive portion which comprises a pair of concentric, rod shaped electrodes for producing a high energy, umbrella shaped plasma discharge, using the inverse pinch technique.

Abstract: A device for initiating combustion of fuels produces a high energy plasma jet by rapidly transferring energy from a capacitive section thereof to an electrode section integral therewith. A plurality of circular capacitor plates disposed in parallel, spaced relationship to each other within an electrically conductive, cylindrical casing filled with dielectric fluid form the capacitive section. The capacitor plates are alternately connected to the casing and to an elongate rod which extends longitudinally through the casing. One end of the rod extends outwardly from an end of the casing and includes a circularly shaped, pointed firing tip which is spaced from the end of the casing and defines one electrode of the device. The end of the casing surrounding the shaft defines the other electrode such that the initial discharge between the electrodes is in the form of a cylindrical sheet. The cylindrical sheet discharge is quickly transformed into a plasma jet by magnetic fields.
