Abstract

PURPOSE:To make the quality of a liquid fuel itself better by using a catalyst body so as to purify the exhaust gas and reduce the quantity thereof, by accommodating a catalyst body into the liquid fuel catalyst device, the catalyst body being composed of a catalyst ceramic having a blended tolumaline and far infrared ray radiation ceramic, and causing the liquid fuel having flown in from an inlet to pass through the catalyst body and flow out from an outlet. CONSTITUTION:A liquid fuel inflows from an inlet 4 and flows out from an outlet 5 after passing through a catalyst ceramic 6 having a blended tolumaline serving as a catalyst body and through far infrared ray radiation ceramic members 7, 8 and 9. This catalyst ceramic having a blended tolumaline causes generation of an electric current high in voltage but weak by a number of electric stone crystals existing in the ceramic surface and having permanent electrodes which alternately become plus and minus electrodes. Far infrared ray radiation ceramic members 7, 8 and 9 cause generation of far infrared rays. Therefore, the liquid fuel is subjected, when passing through the catalyst device, to catalytic action by the actions of the electric current generated from the catalyst body and far infrared rays, and ionization vigorously occurs therein, and chemical changes occur therein to be converted into a good quality liquid fuel.

2. Description of the Related Art When liquid fuel is combusted, it generates exhaust gas containing harmful components as combustion products and incomplete combustion products. This has become a problem as air pollution. Therefore, various purification devices have been proposed for purifying exhaust gas. For example, there are exhaust gas purification devices for automobile engines that completely burn the fuel in the combustion chamber and prevent the generation of harmful components, and exhaust gas emitted from the combustion chamber that contains harmful components. Even though
These include things that are intended to be rendered harmless while being released into the atmosphere. Specifically, the carburetor improvement device, intake air temperature adjustment device,
Examples include an ignition timing control device, a blow-by gas reduction device, a catalytic converter device, an exhaust reburning device, an exhaust gas recirculation device, a fuel evaporative gas suppression device, and a CVCC engine.

SUMMARY OF THE INVENTION In all of the above-mentioned conventional techniques, the liquid fuel combustion device is improved to purify the exhaust gas, or the exhaust gas purification device is used to purify the exhaust gas. Therefore, in Japanese Patent Application No. 2-266101, a liquid fuel catalyst was used to improve the quality of the liquid fuel itself.
Inventions have been proposed to purify exhaust gas. but,
The liquid fuel catalyst ceramic of the invention has the disadvantage that the effect can be obtained only when the rate at which the liquid fuel passes through the catalyst ceramic is equal to or higher than a certain flow rate, and no effect can be expected when the flow rate is low. In view of these points, it is an object of the present invention to provide a liquid fuel catalyst device that solves the above-mentioned drawbacks.

0004

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a liquid fuel catalyst device which is interposed at an appropriate position in a liquid fuel path, in which a catalyst body is placed in a container having an inlet and an outlet for the liquid fuel. A catalyst ceramic containing tourmaline and a far-infrared emitting ceramic are contained, and the liquid fuel flowing in from the inlet passes through the catalyst body and flows out from the outlet.

[0005] Catalytic ceramics containing tourmaline include, for example, those whose main raw materials are acidic refractories, weakly acidic refractories, and granite in addition to tourmaline, and the blending ratio is 10 to 10% tourmaline. 30% by weight,
Acidic refractories 20-40% by weight, weakly acidic refractories 20-40%
% by weight and 10-30% by weight of granite may be mentioned as suitable examples.

The tourmaline (tourmaline) has several compositions depending on its production process, but is basically a silicate mineral containing boron, and the chemical formula of a typical one is as shown in Chemical Formula 1.

[Chemical formula 1] 3{NaX3 Al6 (BO3)
3 Si6 O18(OH9 F)4 }
(X=Mg, Fe, Li, etc.) The acidic refractories are mainly made of furnace material silica, Rouseki, fireclay, chamotte, etc., and the weakly acidic refractories are made of shale, bauxite, sillimanite, etc. is the main raw material. The catalytic ceramic containing tourmaline can be produced by powdering tourmaline, an acidic refractory, a weakly acidic refractory, and granite as described above, adding water to the powder, kneading the powder, molding and drying, and then firing. In particular, tourmaline is powdered and made into microcrystals, but the particles are not particularly limited. A good example is approximately 2 to 3 microns. In addition, the firing temperature for tourmaline permanent electrodes is 950 to 10
Since it is recognized that it disappears at 00°C, the temperature is preferably about 900°C or lower.

[0007] The blending ratio of the tourmaline (tourmaline) powder is set to 5 to 35% by weight because if it is less than 5% by weight, there will be less tourmaline electrodes and weak current will be generated and no effect can be expected; This is because the tourmaline microcrystals are too close together and the electrodes of opposite signs cancel each other out. Therefore, the ingredients other than tourmaline have a total of 95 to 6
5% by weight, and as a result, the spaces between tourmaline microcrystals are filled with highly electrically insulating ceramics such as acidic refractories and weakly acidic refractories.

[0008] The far-infrared emitting ceramic may be any conventionally known ceramic, but one example is one whose main raw materials are alumina, silicic acid, and zirconium oxide. 60% by weight,
Silicic acid 18-25% by weight, zirconium oxide 15-23%
% by weight, titanium oxide 0.5-1.5% by weight, sodium oxide 0.08-0.2% by weight, and iron oxide 0.05-0.
Examples include those formed with a blending ratio of 12% by weight.

[0009]

[Operation] Liquid fuel flows in from the inlet, passes through a catalytic ceramic containing tourmaline as a catalyst and a far-infrared emitting ceramic, and then flows out from the outlet. The catalytic ceramic containing tourmaline is present on the ceramic surface, and a large number of tourmaline crystals with permanent electrodes alternately act as positive and negative electrodes, generating a high voltage but weak current. The far-infrared emitting ceramic generates far-infrared rays. Therefore, when the liquid fuel passes through the passage, it is catalyzed by the action of the electric current generated by the catalyst body and far infrared rays, and ionization becomes active, causing a chemical change and becoming a high-quality liquid fuel. As a result, it is completely combusted, which helps reduce exhaust gas and fuel consumption.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to embodiments shown in the drawings. FIG. 1 is a longitudinal sectional view showing an embodiment of the present invention. In the figure, reference numeral 1 denotes a catalyst container main body made of stainless steel or the like, which is formed into a sealed cylindrical shape, and both ends are shaped like a truncated cone 1a toward the center of the end face. A liquid fuel inlet 4 is located approximately in the center of one end surface 2 of the container body 1.
An outlet 5 is provided approximately at the center of the other end surface 3.

[0011] The container body 1 contains a catalyst ceramic containing tourmaline as a catalyst and a far-infrared emitting ceramic. 6 is a catalytic ceramic compounded with spherical tourmaline; 7 is a spherical far-infrared emitting ceramic; 8 and 9 are far-infrared emitting ceramics. Spherical ceramic as catalyst6,7
are mixed together. The far-infrared emitting ceramic 8 is formed into a disk shape with a large number of through holes 10 as shown in FIG. 2, and the far infrared emitting ceramic 9 has a through hole 11 in the center as shown in FIG. It is formed in the shape of a disc.

Accordingly, the liquid fuel flowing into the container body 1 from the inlet 4 passes through each of the catalyst bodies 6, 7, 8, and 9, and flows out from the outlet 5. In this process, the liquid fuel
It is catalyzed by the action of electric current and far infrared rays generated by the catalytic body, ionization becomes active, chemical changes occur, and high-quality liquid fuel is produced. If the catalytic ceramic 6 and the far-infrared emitting ceramic 7 made of tourmaline are formed into a small spherical shape as in this embodiment, the contact area with the liquid fuel will be widened, and the through holes 10 and 11 will be formed. When the disk-shaped far-infrared emitting ceramics 8 and 9 are interposed in a laminated manner, the liquid fuel is diffused and the flow rate is slowed down, so that the function as a catalyst is sufficiently performed.

Next, the liquid fuel catalyst device of this example shown in FIG. 1 was attached to the liquid fuel path of an automobile and the automobile was driven, and the measurement results were as follows. In a black smoke test using a 1986 Crown Turbo Diesel (2400cc) vehicle, the black smoke content was 51-53% by weight, but it was reduced to 32%. Further, the measurement results of fuel consumption were as shown in Table 1.

[Table 1] According to the above results, it can be seen that the reduction in black smoke is remarkable and the mileage per liter is also much improved as shown in Table 1.

[0014]

[Effects of the Invention] As explained above, in the present invention, the synergistic effect of electric current and far infrared rays on liquid fuel activates ionization, causing chemical changes in the liquid fuel, turning it into a high-quality liquid fuel, and achieving complete combustion. This results in improved fuel efficiency, increased output, reduced black smoke from exhaust gas at the time of combustion, carbon monoxide,
This has the effect of reducing the concentration of carbon dioxide, hydrocarbons, nitrogen carbides, sulfur gas, etc. Additionally, liquid fuel exhaust gas is reduced, which helps prevent global warming. Furthermore, the present invention is effective even when the flow rate of liquid fuel is high, since a catalyst ceramic containing tourmaline in addition to a far-infrared emitting ceramic is used as a catalyst.
