20090194051 | Plasma Generating Ignition System and Associated Method - An apparatus and method for igniting combustible materials in a combustion chamber of a combustion engine using corona discharge plasma from a coaxial cavity resonator. This system and method uses a coaxial cavity resonator in a body adapted to mate with a combustion chamber of a combustion engine. The coaxial cavity resonator is coupled with an energy shaping means that develops the appropriate waveform for triggering radio frequency oscillations in the coaxial cavity resonator. A connection means on the apparatus allows for the apparatus to accept an electrical ignition stimulus from an electronic ignition control system. The coaxial cavity resonator develops corona discharge plasma at a discharge electrode when a sustained radio frequency oscillation results in a standing wave in the coaxial cavity resonator. The corona discharge plasma developed near the discharge electrode ignites the combustible materials in the combustion chamber of the combustion engine. | 08-06-2009 |
20110146607 | Quarter Wave Coaxial Cavity Igniter for Combustion Engines - An apparatus and method for igniting combustible materials in a combustion chamber of a combustion engine using corona discharge plasma from a quarter wave coaxial cavity resonator. A tapered quarter wave coaxial cavity resonator is adapted to mate with the combustion chamber. The quarter wave coaxial cavity resonator is coupled with an energy shaping means, or waveform generator, that develops the appropriate waveform for triggering radio frequency oscillations in the quarter wave coaxial cavity resonator. A loop coupling is angularly positioned within the quarter wave coaxial cavity resonator to match impedances between the quarter wave coaxial cavity resonator and the energy shaping means, or waveform generator. Radio frequency oscillations produce a standing wave in the quarter wave coaxial cavity resonator and a corona discharge plasma develops near the center conductor. The corona discharge plasma developed near the center conductor ignites the combustible materials in the combustion chamber of the combustion engine. | 06-23-2011 |
20110175691 | Compact Electromagnetic Plasma Ignition Device - A quarter wave coaxial cavity resonator for producing corona discharge plasma from is presented. The quarter wave coaxial cavity resonator has a folded cavity made of opposing concentric cavity members that are nested together to form a continuous cavity ending in a aperture. A center conductor with a tip is positioned in the cavity. The folded cavity advantageously permits the coaxial cavity resonator to resonate at a lower operating frequency than an unfolded quarter wave coaxial cavity resonator of the same length. Embodiments of the quarter wave coaxial cavity resonator use narrower apertures to reduce radiative losses, and include center conductors that are reactive load elements, such as helical coils. When a radio frequency (RF) oscillation is produced in the quarter wave coaxial cavity resonator, corona discharge plasma is formed at the tip of the center conductor. The corona discharge plasma can be used to ignite combustible materials in combustion chambers of combustion engines. | 07-21-2011 |
