Abstract: Apparatus and method for a plasma discharge for ignition in an internal combustion engine. A digital electronic system controls ignition performance and can provide an ignition discharge throughout an entire power stroke of a piston in a cylinder. The discharge can be controlled by a signal from a conventional distributor, crank trigger or other source. Controllable discharge of a capacitor occurs through the primary winding of an ignition coil. In addition, the capacitor may be both discharged and recharged in an oscillatory manner through the primary of the ignition coil. Such oscillatory discharging and recharging of the capacitor results in energy being delivered to the spark plug during both discharge and recharge cycles, thereby resulting in the delivery of discharge energy to the spark plug on a substantially continuous basis.

Abstract: A moving fluid containing pollutants including NOx compounds is subjected to a relatively low-power alternating-current dielectric discharge for a relatively long time duration. In this manner, pollutants are oxidized and dissociated while the temperature of the fluid is kept low enough to prevent the formation of new NOx pollutants.
