ABSTRACT:

FIELD OF THE INVENTION
The present invention relates to a combustion promoting device and a method for using it, and in particular, for example, to a combustion promoting device for enhancing combustion efficiency in a combustion equipment such as an internal combustion engine and thereby improving fuel economy and reducing harmful substances such as NOx, SOx, HC (hydrocarbon) contained in the exhaust gas, and a method for using it.
DESCRIPTION OF THE PRIOR ART
A gasoline engine, taken up by way of example as one of internal combustion engines, is generally constructed to obtain power through crankshaft rotation caused by the force of a piston moving toward the bottom portion of a cylinder, in which atomized gasoline and air are at the same time delivered into a combustion chamber of the engine and sparked by a plug so as to react explosively.
In this case, the air supplied through an air intake duct into this combustion chamber streams successively in ionized clusters, bodies of cohering atoms or molecules of nitrogen and oxygen charged with positive or negative electricity.
Since the air thus delivered into the combustion chamber is in a cohering phase formed by multiple and successive ionized clusters, the fuel combustion efficiency cannot be enhanced so much even if the atomized fuel and the oxygen as a component accounting for 21% of the air are brought into an explosive reaction in the combustion chamber.
This is because adjacent clusters of oxygen which partly form the cohering phase are united through the ionic bond. Accordingly the active degree of this oxygen, which may be regarded as a scale of combustibility, is reduced. Therefore the atomized fuel cannot burn well. As a result, there occurs an incomplete combustion of such additives in the gasoline as benzene, aldehyde, antioxidant and anti-freezing agent, and a comparatively large amount of black smoke is produced, which is one of the causes of air pollution.
SUMMARY OF THE INVENTION
Considering this situation, the inventor focused attention on positive ions emitted from ceramic and titanium oxide. That is, he found out that the fuel combustion efficiency can be enhanced when these positive ions succeed in neutralizing ionized clusters of oxygen in the air delivered into the combustion chamber and thereby in dispersing and making the ionized clusters into fine particles, and completed the present invention.
The object of the present invention is to provide a combustion promoting device for enhancing the combustion efficiency in a combustion equipment and thereby reducing the content of such harmful substances as NOx, SOx, HC in the exhaust gas and for making the life of the combustion equipment longer and a method for using the device.
Further, when the combustion equipment is an internal combustion engine, the object is to provide a combustion promoting device which can improve fuel economy and increase power and a method for using the device.
An embodiment of the present invention relates to a combustion promoting device comprising a heat resistant substrate with ceramic and titanium oxide attached thereto for dispersing ionized clusters of cohering atoms or molecules charged with electricity and for making said ionized clusters into fine particles, said ionized clusters constituting a combustible fluid to be supplied into a combustion equipment and to cause a combustion reaction.
There is no restriction to the substrate material, so long as it is heat-resistant. For example, a cloth of glass fiber (woven fabric, nonwoven fabric, knit fabric) may be employed. The material is preferably heat-resistant above 100° C. The substrate is not limited to this type of cloth. For example, the substrate may be formed into a lump. Furthermore, the substrate may be formed into a granule having a predetermined diameter or fine powder. The substrate may be liquid filled in a bag or a container.
Combustion equipment may include various combustion apparatus (boiler, stove, etc.), various internal combustion engines (gasoline engine, diesel engine, propane gas engine, jet engine, etc.) and a thermal power electric generator. Running vehicles with any of these internal combustion engines installed may include a passenger car, a truck, a bus, an auto-bicycle. Various other special utility vehicles (forklift truck, truck crane, shovel loader), a ship, an airplane may also be included.
Combustible fluids may include gasoline, light oil, kerosene, heavy oil, propane, jet fuel. Examples of other fluids are air used during the combustion and cooling water.
There is no particular restriction to the ceramics for dispersing and making ionized clusters into fine particles. Examples of such various semi-conductive substances, carbide, nitride, and boride may include alumina, feldspar, silica, granite, steatite, mica, soda glass, cordierite, barium titanate, potassium niobate, strontium titanate, barium stannate, silicon carbide, molybudenum silicide, lanthanum chromite, zirconia, zircon, chromia, aluminum oxide, silicon nitride, aluminum nitride, gallium arsenide, beryllia, glass ceramic, mullite, ferrite.

It may also be applied onto the substrate surface by spraying or may be impregnated into the substrate in some proper method. Further a lump of ceramic or titanium oxide may be attached onto the substrate surface or into the substrate.
Another effects of better fuel economy and higher power can be obtained by providing aluminum to the substrate
