Description
SPECIFICATIO~
Title of the Invention Fuel activation method and fuel activation device Field of the Invention This invention relates to a fuel activation method and a fuel activation device for activating liquid and gaseous fuels in internal combustion engines, external combustion engines and other apparatus using various types of fuel~.
Background of the Invention In general, with`fuels used in internal combustion en~ines, external combustion engines, and other combustion apparatus, exhaust gases are generated by combustion to release various types of noxious chemical sub~tances into the atmosphere, thus causing an environmental pollution.
These noxious chemical substances include, for example, CO, HC, NOx, and SOx.
Heretofore, to suppress generation of such noxious chemical substances, fuel combustion efficiency has been improved by improving the quality of fuels used or by improving various combustion devices. In addition, the exhaust gases released have been treated by a variety of exhaust gas removing devices using catalysts to prevent ~,.
.
. ~
pollution.
However, such prior art methods have been insufficient to reduce pollutive substances, and the improvement of fuel quality has been difficult in view of the costs.
Summary of the Invention With a view to overcome such problems with the prior art methods, it is a primary object of the present invention to provide a fuel activation method and a fuel activation device which can enhance the fuel combustion efficiency and reduce concentrations of noxious e~haust gases.
In accordance with the present invention which attains the above object, there is provided a fuel activation method oomprising causing a fuel to contact with a functional ceramic for activation of the fuel. There is also provided according to the present invention a fuel activation device comprising a container unit disposed in a fuel pipe to introduce a fuel into a combustion engine, and a far-infrared-radiant ceramic capable of contacting with the fuel passing through the container unit.
Brief DescriDtion of the Drawings These and other objects as well as advantages of the present invention will become clear by the following description of a preferred embodiment of the present invention with reference to the accompanying drawing~.
Figs.l to 8 are schematic cross Qectional views of embodiments of the fuel activation device according to the present invention. Fig.9 i9 a schematic view of an internal combustion engine using the fuel activation device shown in Fig.2.
Detailed Description of the Invention A preferred embodiment of the present invention will now be de~cribed in detail. Fig.1 i~ a schematic view of the fuel activation device according to the pre-~ent invention. Referring to Fig.l, this embodiment of the fuel activation dev}ce (hereinafter simply referred to as '`activation device'`) 10A has a container unit 12 disposed in a fuel pipe 11 connecting a fuel tank and a carburetor, for example, of an internal combustion engine, and a granular far-infrared-radiant ceramic 13 as A functional ceramic charged in the container unit 12.
More specifically, referring to Fig.9, the activation device 10A indicated as 10 in Fig.9 is disposed, for example, in the fuel pipe 11 to feed a fuel 22 from a fuel tank 21 to a carburetor 23 of an internal combu~tion engine 20, in which the fuel 22 pa-Q~ing through the activation device 10A is activated and efficiently combusted in a combu~tion chamber 24. Numeral 25 indicate~ a fuel pump to feed the fuel 22, numeral 26 indicates a fuel filter, numeral 27 indicates an air cleaner, and numeral 28 indicates exhaust gas.
With the above arrangement, as the fuel 22 passes through the activation device lOA, the fuel 22 absorbs far-infrared energy rad~ation of the fsr-infrared-radiant ceramic 13 charged in the container unit 12 to under~o hi~h-value-added heating by far-infrared rays.
The far-infrared-radiant ceramic 13 includes known metal o~ide ceramics such as ZrO~, SiO2, Al20s~ Fe20s, CaO, TiO2, MnO, MgO, and BaO, which may be used in ade~uately molded forms from granules or powders capable of efficiently radiating far-infrared rays.
This embodiment uses a far-infrared-radiant ceramic which, when heated, is capable of radiating large amounts of far-infrared rays, however, alternatively the present invention can use functional ceramics such as ThO2, ZrO2, K~O~nTiO2, BeO, diamond, WC, TiC, BsG, SiC, SisN "

Claims (2)
1. A method of fuel activation comprising contacting said fuel with a functional ceramic emitting no infrared rays other than far infrared rays whereby said fuel is activated before combustion, Wherein said fuel contacts said ceramic at a point between a fuel tank and a fuel injector or carburetor, said ceramic being heated to a temperature at least 1°C. higher than the temperature of said fuel before contact with said ceramic and less than the temperature at which substantial vaporization occurs.
2. A fuel activation device comprising a container unit in a fuel pipe introducing fuel into a combustion engine, said container unit being positioned between a fuel tank and a fuel injector or carburetor, a functional ceramic emitting no infrared rays other than in the far infrared region being contained in said unit and adapted to contact said fuel passing through said unit, whereby said fuel is activated, said device further comprising a heater for said ceramic which increases the temperature of said ceramic to a temperature at least 1°C. over the temperature of said fuel prior to contacting said ceramic and less than the temperature at which substantial vaporization takes place.
