The gasoline engine mainly contains gasoline, the diesel engine contains light oil or heavy oil,
Kerosene or light oil engines use kerosene or light oil, and steam engines such as boilers mainly use heavy oil. Each of these fuels is a finite natural resource that has been produced over many years, and is a property of mankind that should be cherished and left to descendants.

Heretofore, it has been proposed to use ceramics, ore, etc. in order to increase the combustion efficiency of gasoline engines and the like of automobiles. For example, JP-A-9-22890
No. 5 proposes immersing a ceramic ball in a fuel to activate the fuel, or coating a part of an intake system or an exhaust system with a ceramic coating. Also, ceramic balls containing radioactive substances are said to be effective.

[0005] In some of these proposals, however, the effect of improving the combustion efficiency and the effect of the exhaust gas component is recognized, but there is a problem that the effect is unstable and cannot be put to practical use. That is, there are times when there is an effect and sometimes no effect, and the effect is not stable because the magnitude of the effect is not stable. Further, in general, ceramics and ores are in a powdery or lump form, which is inconvenient to be directly mounted on a heat engine, and it is necessary to form these materials into a shape that can be easily mounted for practical use.

[0016]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the radiation member and the heat engine according to the present invention will be described in detail with reference to the drawings.

The intensity of the radioactivity described in the present invention is measured by a Geiger-Muller counter (TG, manufactured by Aloka Corporation).
S-136) was measured under the following conditions. That is, as described in FIG.
A plate-shaped measurement sample 16 having a length of m was cut out and placed on a sample table 15 so that the surface 13 to be measured was located 5 mm below the detection surface 12 having a diameter of 5 cm of the Geiger-Muller counter. The value of the background was subtracted from the value thus measured, and the value of 1/4 was defined as the radioactivity intensity per square centimeter. When the measurement object was not flat, a flat measurement sample was separately manufactured under the same conditions as the measurement object, and the measurement result was substituted.

The flexible sheet referred to in the present invention refers to a flexible film, knitted fabric, paper, non-woven fabric, thick sheet, or a composite sheet thereof, etc. It refers to a sheet-like material in which synthetic fibers or the like are combined with a resin or entangled with a needle or the like. Also,
The silicone resin sheet means that the main component of the resin constituting the sheet is a silicone resin, and may include other resins, plasticizers, and the like.

Radioactivity is imparted mainly by adding radioactive ore, but powdered radioactive ore is mixed in advance into various resin raw materials such as films, thick sheets, fibers and the like, or formed into sheets. The post-processing is performed by attaching powdery radioactive ore dispersed in a resin or the like. According to the post-processing, in the case of a sheet containing voids such as a knitted or woven fabric or a nonwoven fabric, radioactive ore can be embedded into the sheet by impregnating the voids with a resin. For etc., only the surface will have radioactivity since it is only applied to that surface.

The radioactive ore used in the present invention is not particularly limited, and the radioactive strength of the flexible sheet produced by using the ore as described above is 80 counts / min or more per square centimeter of surface. 5,000 counts /
It only has to be in the range of minutes or less. Generally speaking,
Every ore has more or less radioactivity. If the ore has a large radioactivity, a flexible sheet that satisfies the above-mentioned radioactivity intensity can be manufactured by adding a small amount, but if the ore has a small radioactivity, a large amount must be added. . The present inventors have examined many types of ores, and as a result, it is a so-called inoue ore, an ore collected from a mine in Otsu City, Shiga Prefecture,
The use of ores consisting mainly of feldspar is preferred, especially preferred the activity is 150 or more per square centimeter.
It was found that using Inoue ore at a count / min or more. The measurement of the radioactivity was performed according to the above-described method for measuring a flexible sheet, by spreading 2.5 g of ore powder having a size of 1 mm or less over a 2 cm × 2 cm area.

[0021] The radioactive member of the present invention comprises gasoline, light oil,
It is used for activating fuel such as heavy oil or activating air taken into the heat engine to improve the combustion efficiency of various heat engines. It is also used to decompose harmful components of exhaust gas from various heat engines. Or, to purify water by removing or decomposing phosphorus or chlorine in water,
It is used to purify air by removing or decomposing off-flavor components and harmful components in the air. Alternatively, it is worn near the body as underwear or the like and used for maintaining and promoting health.

In particular, a radioactive member made of a flexible sheet is useful and highly useful because it can be easily mounted along various curved shapes. The radiation irradiation effect can be enhanced because it can be mounted in close contact with the outer or inner surface of a container such as a fuel tank or an air cleaner, or a pipe such as a fuel transport pipe, a connection pipe of an intake system, or an exhaust pipe. For this reason, there is an advantage that the flow of fuel or air is not hindered even when mounted on the inner surface, and the outer surface can be mounted even in a relatively narrow space.

If a flexible sheet in the form of a carpet, mattress, wallpaper, ceiling material, or other interior material is used, the odorous and harmful components of the indoor air are removed or decomposed to purify the air. In addition to the effect, the effect of maintaining and improving the health of residents is also obtained. Radioactivity can be imparted to these flexible sheets by mixing radioactive ore into a backing material such as a carpet or a paste material such as a wallpaper.

In general, nonwoven fabrics are bulkier and have a higher porosity than knitted fabrics. Therefore, a large amount of ore powder can be contained in the void portion, and a flexible sheet having high radioactivity can be obtained. In general, non-woven fabrics have less anisotropy in physical properties than knitted fabrics. For this reason, there is a feature that it can be easily attached in close contact with a site having a complicated shape. Furthermore, since the nonwoven fabric can be formed by mixing various types of fibers relatively freely, depending on the application, use fibers having excellent heat resistance, chemical resistance, weather resistance, etc. It is possible to increase.

The bonding method of the nonwoven fabric used in the present invention is not particularly limited. However, the nonwoven fabric formed by the needle punching method is particularly bulky, and has a feature that a large amount of powdered ore can be held in the internal voids. It is suitable for mounting to the intake system or mounting on the outer surface of the fuel supply system. Further, the nonwoven fabric bonded by heat fusion or an adhesive has a relatively smooth surface, and therefore has low contact resistance with a fluid, and is suitable for mounting the fuel supply system on the inner surface. The amount of radioactive ore contained in the nonwoven fabric is preferably from 300 g to 3 kg per m ² .

The radioactive member made of a nonwoven fabric is effectively used as an air filter used for an air cleaner of an automobile or an air filter of a cooling / heating device. Air passing through the fine voids of the nonwoven fabric is physically collected and removed by foreign substances, and is purified by radiation emitted from the nonwoven fabric. The air passing through the air filter receives very strong radiation because it passes very close to the non-woven fibers constituting the radiation source, and the air filter is designed to allow air to pass relatively slowly, so that the air is irradiated for a relatively long time. Therefore, a particularly large air purification effect can be obtained.

Since the silicone resin sheet has high safety and excellent heat resistance and is not swollen by oils, it is particularly suitable for use in contacting a fuel such as gasoline or light oil to activate the fuel. Further, in an intake system such as a gasoline engine, a silicone resin sheet is preferably used because engine oil is easily mixed therein.

The type of silicone resin used is not particularly limited, and commercially available silicone resins can be used. Also,
The thickness of the silicone resin sheet is 2 mm to 15 mm, although the amount is 1kg / m ² ~15kg / m ² position is preferred ore contained, the present invention is not limited to these ranges, because they are applied in a wider range is there.

Another particularly effective form of the radioactive member is a layered, plate-like, or substantially cylindrical ceramic sintered body. A radioactive member made of a sintered body has excellent heat resistance and is particularly suitable for use in the vicinity of an engine or an exhaust system. Further, since the radioactive ore trapped in the sintered body does not desorb, troubles such as filter clogging hardly occur. In addition, since the sintering can be performed in a shape previously adjusted to the shape of the mounting portion, the mounting can be performed easily and in a stable form.

The ceramic sintered body is prepared by mixing radioactive ore into clay or the like which is usually used for making ceramics.
It is manufactured by firing at about 1300 ° C. The mixing amount of the radioactive ore is preferably from 10% by weight to 95% by weight, and more preferably from 30% by weight.
90 weight percent. It is preferable to increase the mixing amount because the thickness of the ceramic sintered body can be reduced, but there is a practical limit because the strength of the sintered body is reduced. It is also possible to include a ceramic or the like that emits far-infrared rays in a part of the raw material.

The layered ceramic sintered body refers to a ceramic sintered body applied and sintered on a heat-resistant substrate surface, and is preferably used in a thickness of 0.1 mm to 10 mm. It is not limited to this range. Also,
The plate-shaped ceramic sintered body means a ceramic sintered body formed into a plate irrespective of a planar shape or a curved surface shape.
Further, the substantially cylindrical ceramic sintered body means a substantially cylindrical, substantially polygonal cylindrical, substantially elliptical cylindrical or other ceramic sintered body, and even if the wall surface is slightly inclined or bent. Alternatively, the bottom opening and the top opening may be slightly narrowed. Further, in order to increase the contact area with fuel or air, irregularities, projections, or the like may be provided on the surface. Alternatively, a number of holes may be provided in the tubular portion so that fuel and air flow across the tubular portion.

The radioactive member according to the present invention activates fuel such as gasoline, light oil, or heavy oil, activates air taken into a heat engine, decomposes harmful components of exhaust gas, removes phosphorus in water, The mechanism for removing or decomposing chlorine and the like and for removing or decomposing off-flavor components and harmful components in the air is not clear. The present inventors have paid attention to various mysterious phenomena observed at the ore excavation site, and as a result of repeated examinations experimentally or empirically, they have come to the invention of a member having the above various effects. is there.

However, when radiation such as β-rays, α-rays, γ-rays, or neutrons is irradiated, atoms and molecules in a substance are ionized or radicalized, or are excited to an active electronic state. It is well known that various chemical reactions are promoted. Therefore, although the effects of the present invention are presumed to be mainly due to the same action mechanism, the above-mentioned extremely large effects cannot be sufficiently explained quantitatively.

In the radioactive member of the present invention, the intensity of radioactivity is not less than 80 counts / min per square centimeter.
000 counts / minute or less. If it is less than 80 counts / minute, the effect is small and it cannot be used practically. Also, 5,
In order to make it larger than 000 counts / min, a large amount of radioactive ore to be mixed must be used, so that various physical properties such as the strength of radioactive members are reduced. Rises,
It is not preferable because it may adversely affect health.

Next, the heat engine according to the present invention will be described in detail using a gasoline engine of an automobile as an example. FIG. 2 schematically illustrates the configuration of the gasoline engine 10 of the vehicle. That is, the fuel supply system 23 including the fuel tank 18, the fuel filter 20, the fuel supply pipe 22, etc., the air filter 24
, An intake system 27 including an intake pipe 26, a muffler 28,
Exhaust system 33 including sub-muffler 30, exhaust pipe 32, etc.
And so on. The fuel gasoline is vaporized from the fuel tank 18 through the fuel filter 20, mixed with the air sucked in the mixing section 21, supplied to the engine 11, ignited and explosively burned, and its thermal energy is Converted to mechanical energy. The products and unburned products of the combustion are discharged into the atmosphere as exhaust gas via the exhaust system 33.

In the heat engine of the present invention, at least one of the fuel supply system 23, the intake system 27, and the exhaust system 33 has a radioactivity intensity of 80 counts / cm 2.
A flexible sheet of not less than 5,000 counts / minute or more, or a radioactive member made of a layered, plate-like, or substantially cylindrical ceramic sintered body is mounted. That is, in the gasoline engine 10 illustrated in FIG. 2, the fuel tank 18, the fuel filter 20, the inner surface and the outer surface of the fuel supply pipe 22 and the like constituting the fuel supply system 23, the air filter 24 and the intake pipe constituting the intake system 27. 26 and other inner and outer surfaces, exhaust system 3
The radioactive member is attached to at least one of the inner surface and the outer surface of the muffler 28, the sub-muffler 30, the exhaust pipe 32, and the like that constitute the 3.

The method for mounting the radioactive member is not particularly limited. It may be fixed by bonding, using a bolt or the like, or winding a string or a tape. Alternatively, it may be formed in advance in a shape suitable for a portion to be mounted, and fixed by insertion or fitting. Radiation such as β-rays, γ-rays, or neutron rays has relatively high permeability and can penetrate iron plates, etc., so it can act on internal fuel, air, exhaust gas, etc. even when mounted on the outer surface of each part. .

When a radioactive member is attached to a part of the intake system, the intake air is activated and the combustion efficiency of the heat engine is improved, so that effects such as improvement of fuel efficiency and reduction of harmful components in exhaust gas are obtained. is there. In particular, when the radioactive member is mounted on the air cleaner, the air stays in the air cleaner for a relatively long time, so that the air before being supplied to the engine can be sufficiently activated. Preferably, it is good to be mounted inside an air cleaner that comes into direct contact with air, and particularly preferably, a radioactive member made of a silicone resin sheet having excellent oil resistance is attached to the inner surface, or a radioactive member made of a nonwoven fabric is used as an air filter element. It is composed of

The fuel such as gasoline, light oil, or heavy oil is activated by the radioactive member mounted on a part of the fuel supply system, and the combustion efficiency is improved. As a result, fuel efficiency is improved, and the ratio of harmful components such as HC, CO, NO, and SO in the exhaust gas is reduced. In particular, if the fuel tank is mounted on a fuel tank in which the fuel stays for a relatively long time, the time for receiving the radiation is prolonged, and sufficient activation is possible. When mounted on the inner surface of the fuel tank, it is preferable to use a radioactive member made of a silicon resin sheet or a ceramic sintered body. At the same time, the effect can be further enhanced by putting the ceramic radioactive member sintered in a ball shape into the fuel tank.

It is also useful to provide a fuel reforming section equipped with a radioactive member between the fuel tank and the fuel filter. Since the fuel reforming unit is newly provided as compared with the case where the fuel reforming unit is mounted on an existing fuel tank, it is possible to freely design the radioactive member so that the radioactive member is easily mounted and functions effectively. In particular, mounting inside the fuel cell is facilitated, and a silicon resin sheet, a ceramic sintered body, or the like can be provided as a fuel reforming section provided in advance inside.

FIG. 3 shows an example of a shape particularly useful as a fuel reforming section. That is, the fuel reforming section 34 is provided as a vertical substantially cylindrical body, and a fuel inlet 36 is provided above and a fuel outlet 38 is provided below so as to sandwich a tubular section 35 provided in the middle. ing. And the cylindrical part 35
The radioactive member 37 is mounted over almost the entire circumference of the inner wall surface. The liquid fuel such as gasoline introduced from the fuel inlet 36 fills the cylindrical portion 35, forms a gentle laminar flow, proceeds downward, and is discharged from the fuel outlet 38. Therefore, the liquid fuel such as gasoline receives the radiation uniformly from the radioactive member 37 mounted over almost the entire inner wall surface of the cylindrical portion 35 and is sufficiently activated. It is not preferable to use a horizontal fuel reforming section having a fuel inlet and a fuel outlet on the left and right sides, since it is difficult to remove the upper air layer and fill with fuel to make a uniform flow. In the present invention, the fuel outlet 38 may be provided above the tubular portion 35 and the fuel inlet 36 may be provided below.

When a radioactive member is mounted on a part of the exhaust system, SO _X , NO _X , HC, C
There is an effect that harmful components such as O are removed or decomposed and reduced. It is preferable to attach a radioactive member made of a ceramic sintered body with excellent heat resistance to the exhaust system at a relatively high temperature,
It is particularly preferable to mount it in a muffler that has a wider inside compared to other parts and is easy to operate such as attaching and detaching. It is preferable to mount it along the inner surface as a cylindrical sintered body, or to mount it as a sintered body provided with a vent so as to cross the flow path of exhaust gas.

In addition, the present invention does not depart from the gist of the present invention, so long as the material and shape of the radioactive member, the type of the radioactive ore, the method of mixing the radioactive member with the radioactive member, the site where the radioactive member is mounted on the heat engine, the mounting method, etc. Can be implemented in various modified, modified, and modified forms based on the knowledge of those skilled in the art.
