ABSTRACT:
A transmission cable (30, 50) for an ignition system of a fuel burning engine has a body of electrical insulation (31, 51). The cable has embedded in its insulation either a distributed or lumped parameter capacitive element (32-34, 52-53) connected in parallel with either a distributed or lumped parameter resistive element (36, 56) which coact to increase the energy delivered to an igniter and hence to a fuel nodule. An igniter for such fuel burning engine has an electrical insulator (20, 520) and an electrode structure (130, 330, 530). The igniter may have a ceramic magnet insulator which accelerates the arc plasma and raises the arc's energy level. Arc transfer members (137-138, 537-538, 537'-538') are partially embedded in the insulator enabling long arcs to be supported. Configurations of the igniter include a capacitor (132-133, 332-333, 532) in parallel with a resistor (134, 334, 533), wherein the parameter values of the capacitor and resistor are such as to produce first order poles with only real parts in the complex plane defining the ignition current.
