Abstract
A non-thermal plasma assisted combustion fuel injector that uses an inner and outer electrode to create an electric field from a high voltage power supply. A dielectric material is operatively disposed between the two electrodes to prevent arcing and to promote the formation of a non-thermal plasma. A fuel injector, which converts a liquid fuel into a dispersed mist, vapor, or aerosolized fuel, injects into the non-thermal plasma generating energetic electrons and other highly reactive chemical species.
Claims16
A non-thermal plasma assisted combustion fuel injector, comprising:
- a. an outer electrode and an inner electrode that provide surfaces to create an electric field therebetween;
- b. a high voltage power supply configured to induce said electric field and to create a non-thermal plasma between the inner and outer electrodes;
- c. a dielectric material, operatively disposed between said outer electrode and said inner electrode to prevent arcing and promote the formation of said non-thermal plasma;
- and,
- d. a fuel injector configured to convert a liquid fuel into a dispersed mist, vapor, or aerosolized fuel;
- and disposed to subject said converted fuel to said non-thermal plasma.
