Patent ID: 7617815

Claim:
A fuel activation device for exciting hydrocarbon fuel of an internal combustion engine and for thereby achieving efficient combustion of the fuel in the engine, said engine including a fuel line, said device comprising at least two separate infrared emitting bodies disposed on said fuel line whereby fuel used for the engine passes adjacent or in contact with the emitting bodies, wherein a first infrared emitting body includes a first composition of oxides and a second infrared emitting body includes a second composition of oxides, wherein each composition includes one or more oxides selected from the group consisting of zirconium oxide, cobalt oxide, titanium oxide, and magnesium oxide, wherein at least one of the selected oxide, for each composition, is at least 2 weight %, and wherein the first composition is selected to provide a first specific peak wavelength and spectral luminance in the range of 3 to 20 um and the second composition is selected to provide a second and different specific peak wavelength and spectral luminance in the range of 3 to 20 um.
