  However, all of the above fuel reforming techniques perform fuel reforming by electromagnetic wave irradiation. However, since such electromagnetic waves depend on permanent magnets and radioactive substances, appropriate control of electromagnetic wave intensity, electromagnetic wave irradiation The preparation of the body was difficult, and the obtained effect was also unstable.

  In the present invention, an electromagnetic wave generating part formed of a conductive material is disposed in the vicinity of the fuel to be processed in a non-contact state with the fuel to be processed, and a power supply device is connected to the electromagnetic wave generating part. By applying a voltage of 30000 V with an alternating current, an electromagnetic wave is applied to the fuel to be treated, and the chemical reaction activity of the fuel molecules is enhanced by the electromagnetic wave, thereby solving the above-mentioned problem.

In short, according to the present invention, since the power supply device that outputs an alternating current with a voltage of 800 to 30000 V is connected to the electromagnetic wave generating part formed of a conductive material, the electromagnetic wave generating part is disposed in the vicinity of the fuel to be treated to irradiate the electromagnetic wave. As a result, in the gaseous fuel, the electrons constituting the molecules of the gaseous fuel can be excited, the chemical reaction activity with oxygen can be increased, and the combustion efficiency can be improved.
In liquid fuel, electrons in liquid fuel molecules are excited, and molecular assemblies (clusters) formed by liquid fuel molecules are subdivided to increase the efficiency of vaporization (atomization) by fuel injection, It is possible to increase the chemical reaction activity and improve the combustion efficiency.
Therefore, it is possible to completely burn the fuel and suppress the generation of incomplete combustion products such as CO, HC, PM, etc. Further, the fuel consumption rate is improved and the fuel consumption is low, so the CO ₂ emission is reduced. You can also.

  By interposing a resistor between the power supply device and the electromagnetic wave generation unit, the current output to the electromagnetic wave generation unit is in the range of 0.02 to 0.4 mA, so that the electromagnetic wave generation unit during operation is temporarily touched. However, safety can be ensured without electric shock.

  Since it has an orthogonal converter that converts direct current input to alternating current and outputs it to the power supply, it can be mounted on a car and fuel reformed using the power supplied by the existing secondary battery to the car. I can do it.

  The electromagnetic wave generating part is housed and sealed in a sheath made of an electromagnetic wave transmitting material, and a liquid-proof process is applied to the lead wire connected to the inside and outside of the sheath and connecting the electromagnetic wave generating part and the power supply device while maintaining the sealed state. As a result, the electromagnetic wave generating part is disposed with the sheath in the fuel tank into which the fuel to be treated is injected, and the fuel reforming (fuel activation) process can be performed extremely easily and easily.

Since the electromagnetic wave generating part is formed in a rod shape and a power supply device is connected to the starting end of the electromagnetic wave generating part, alternating current reciprocates between the starting end of the electromagnetic wave generating part, and the electric and magnetic fields generated by the reciprocating current fluctuate without interruption. In addition, strong electromagnetic waves are generated.
In addition, since the outer diameter is unevenly formed between the start and end of the electromagnetic wave generating part, the current passing cross-sectional area is different in each part, so that the passing charge amount changes accordingly, and the generated electric and magnetic fields are constantly The electromagnetic wave fluctuates in a complicated manner and has a large fluctuation amount (the amplitude, the vector, etc. are considered to fluctuate in a complicated manner during a very small time).
In order to irradiate the fuel to be treated with electromagnetic waves with such large fluctuations, the force received by the electrons in the fuel molecules changes at high speed in both strength and direction, causing the electrons in the fuel molecules to vibrate, thereby exciting the electrons. In other words, the bond between molecules due to electrostatic force is broken, and an active fuel (reformed fuel) in which a cluster of liquid fuel molecules is further finely divided is generated.

  Since the electromagnetic wave generating part is formed by projecting a protrusion between the beginning and end of the rod-shaped conductive part core, the current passing cross-sectional area differs greatly between the protrusion and the concave part, and the generated electric and magnetic fields vary more greatly. Therefore, an electromagnetic wave having a larger fluctuation amount is generated, and fuel reforming can be performed more efficiently.

  A plurality of conductor wires are bundled to form a conductive part core, and a conductive wire is wound around the conductive part core to form a protrusion, so that different electric and magnetic fields are generated by electrons flowing individually through each conductive line. However, the behavioral change of the electromagnetic wave generated by the synthesis is further complicated, and the practical effect such as the ability to further improve the fuel reforming efficiency is significant.

It is a schematic diagram which shows the use condition of the fuel reformer which concerns on this invention. It is an enlarged view of the electromagnetic wave generation | occurrence | production part in FIG. It is AA sectional drawing of FIG. It is a longitudinal cross-sectional enlarged view of FIG. 2 upper part side.

Hereinafter, the fuel reforming apparatus and method of the present invention will be described in detail.
As shown in FIGS. 1 to 4, the fuel reformer of the present invention houses an electromagnetic wave generation unit 2 formed of a conductive material in a sheath 1, and the start end (upper end in the drawing) of the electromagnetic wave generation unit 2. The power supply device 4 is connected to the power source 4 via the conductor 3.
Further, an orthogonal transformer 5 that converts a direct current input from the power source P into an alternating current and outputs the alternating current is provided, and an output from the orthogonal transformer 5 is connected to the power supply device 4.

The specific configuration of the power supply device 4 is not particularly limited as long as it can output a high-voltage alternating current. For example, as shown in FIG. 1, the power supply device 4 includes a transformer 6 that boosts alternating current. The output from the vessel 6 may be connected to the electromagnetic wave generator 2.
If the output of the power supply device 4 is less than 800V, the intensity of the generated electromagnetic wave is low and the fuel is not reformed, and if it exceeds 30000V, the combustion efficiency by the obtained reformed fuel and the amount of incomplete combustion products generated are further changed. Therefore, the output voltage of the power supply device 4 may be in the range of 800-30000V.
In consideration of the voltage of the power supply P, the transformer 6 may be appropriately selected so that the voltage in the above range is applied to the electromagnetic wave generator 2, and in FIG. 1, 7 is a resistor. By interposing a resistor 7 between the transformer 6 and the electromagnetic wave generator 2, the current flowing through the electromagnetic wave generator 2 should be kept low to improve safety, and at less than 0.02 mA The intensity of the generated electromagnetic wave is low and the fuel is not reformed, and if it exceeds 0.4 mA, the danger increases, so a range of 0.02 to 0.4 mA is preferable.

The sheath 1 is a cylindrical container with one end closed and the other end opening made of a material that can transmit electromagnetic waves (for example, synthetic resin). A lid body 8 is provided at the upper end opening, and an empty space is formed in the center of the lid body 8. A hole 9 is penetrated, the lead wire 3 is inserted into the hole 9, the lead wire 3 is communicated with the inside and outside of the sheath 1, and packings 10 and 10 a are provided around the hole 9 on the inner and outer surfaces of the lid 8. The gap between the conductor 3 and the lid 8 is sealed to keep the sheath 1 sealed.
Moreover, the conducting wire 3 is naturally covered with an insulating film, that is, liquid-proofed.

The electromagnetic wave generator 2 may be formed in a columnar shape or a flat plate shape, but it is better to form it in a spindle shape, for example, so that the outer diameter of the electromagnetic wave generator 2 is not uniform.
In addition, a bar-shaped conductive part core 11 is formed, and a plurality of protrusions 12, 12a,... Are provided around the conductive part core 11 at appropriate intervals between the start end and the other side end, and the electromagnetic wave generating part 2 In this way, by making the outer diameter of the electromagnetic wave generator 2 non-uniform, the cross-sectional area of the current is different in each part, so that the amount of passing charge changes accordingly, and the generated electric and magnetic fields are The electromagnetic wave fluctuates constantly and becomes a large amount of electromagnetic waves.

  In this embodiment, as shown in FIGS. 3 and 4, a plurality of conducting wires 13, 13 a... Are bundled to form a rod-shaped conducting portion core 11, and the conducting wires 14, 14 a. Since they are wound and formed as protrusions 12, 12 a, electrons flow individually through the conductors by applying a high voltage, and different electric and magnetic fields are generated from the conductors. As it behaves extremely complex.

The present invention is suitable for reforming gaseous fuels such as methane, propane, and butane, and liquid fuels such as gasoline, kerosene, light oil, and heavy oil.
For example, gasoline is a fraction having a boiling point range of about 30 to 200 ° C. in petroleum, and is a mixture of paraffinic, naphthenic, olefinic, and aromatic hydrocarbon compounds having 4 to 10 carbon atoms. , Mainly composed of bonds of carbon (C) and hydrogen (H). Due to the difference in electronegativity of both atoms, electrons are only slightly distributed on the carbon side, carbon atoms are slightly negatively charged, The atoms are slightly positively charged.
This positive / negative charge is sterically counteracted when the carbon atom is located at the center of gravity of the regular tetrahedron and the hydrogen atom is located at the four vertices, like methane, and no polarity is produced. Since the three-dimensional shape of the hydrocarbon molecule having 2 or more carbon atoms having a zigzag shape, a weak polarity is generated without canceling out the charge bias.
Therefore, the hydrocarbon molecules in gasoline attract each other by electrostatic force so that a plurality of the molecules cancel each other's polarity, and gather to form a cluster.

  When the liquid reformer of the present invention irradiates the electromagnetic waves having the extremely complicated behavior described above to the liquid fuel that forms clusters in this way, the electrons of the hydrocarbon molecules are excited and the electrons in the hydrocarbon molecules are excited. Since the strength and direction of the force that is applied fluctuate at high speed in both strength and direction, the electrons in the hydrocarbon molecule and the molecule itself are vibrated, which weakens the bonding force involved in the formation of the cluster, breaks the bond, and carbonizes. An active fuel is produced in which the clusters of hydrogen molecules are further finely divided.

This active fuel is divided into clusters, so that when it is vaporized by fuel injection (atomization), it becomes finer droplets than in the case of normal liquid fuel, and it is mixed and dispersed with oxygen. Is more fine and uniform, and the electrons in the atomized fuel molecules are in an excited state, so that the chemical reaction activity is high, and the fuel burns well and burns completely.
Also, in the case of gaseous fuel, the electrons in the fuel molecules are excited, so that the fuel burns much better and burns completely.

The following tests were conducted using the fuel reformer of the present invention.
First, as shown in FIG. 1, gasoline (processed fuel F) is supplied to a fuel tank T of a gasoline vehicle (registered as a new car in May 2005), and electromagnetic waves stored in a sheath 1 in the processed fuel F. The generator 2 was immersed, and the sheath 1 was fixed to the fuel tank T by appropriate fixing means (not shown).
Next, the engine was started, exhaust gas was collected in an idling state, and the concentration of incompletely combusted substances (CO and HC) in the exhaust gas was measured with HORIBA MEXA-324J (manufactured by Horiba, Ltd.).
Next, the power supply device 4 is started, a high voltage is applied to the electromagnetic wave generator 2 under the conditions of a voltage of AC 2000V and a current of 0.04 mA, and the exhaust gas is collected after idling for about 5 minutes. The concentration of was measured.
As the power source P, a secondary battery (output DC 12V) mounted on the test vehicle was used.
The measurement results are shown in Table 1 below.

As described above, according to this test, the amount of HC emission decreased and the odor was not brominated.
Although no change is observed for CO, it is because the concentration is below the detection limit of the measuring instrument used, and it is considered that CO is also decreasing due to a decrease in HC emissions.

As for the diesel vehicle (registered as a new vehicle in July 1991), the electromagnetic wave generator 2 housed in the sheath 1 in the fuel to be treated F (light oil) injected into the fuel tank T, as in the case of the gasoline vehicle. To the “Notification that defines the details of safety standards for road transport vehicles (March 25, 2008), Attachment 109, Method for Measuring Light Absorption Coefficients of Exhaust Emissions during No-Load Rapid Acceleration” by the Ministry of Land, Infrastructure, Transport and Tourism Based on this, PM (particulate matter) measurement before and after fuel reforming was performed.
The application conditions to the electromagnetic wave generator 2 are as follows: voltage AC 2000 V, current 0.06 mA, application time (fuel reforming treatment time) 5 minutes, and the power source P is a secondary battery mounted on the test vehicle (output DC 24 V). Was used.
In addition, AVL DISMOKE 4800 (manufactured by AVL LIST GMBH (Austria)) was used for PM (particulate matter) measurement.
The measurement results are shown in Table 2 below.

According to this test, the light absorption coefficient decreased, and a decrease in the amount of PM was observed.
As described above, in both the above tests for gasoline and diesel vehicles, exhaust gas purification was observed, but this was caused by the excitation of fuel molecule electrons by electromagnetic waves and the fragmentation of fuel molecule clusters, resulting in combustion efficiency. It is thought that this is because the fuel efficiency has improved, and the fuel efficiency is also expected to improve for the same reason.

  In both of the above tests, a fuel reformer in which the electromagnetic wave generating unit 2 is housed in the sheath 1 is used. However, the sheath 1 may be omitted, and although not shown, for example, a fuel tank is formed of an electromagnetic wave transmissive material. It is only necessary to arrange an exposed electromagnetic wave generating part around the fuel tank, or to form an electromagnetic wave permeable fuel tank in a horizontal cross-section donut shape, and to provide an exposed electromagnetic wave generating part in the center of the donut shape. In the fuel reforming method of the present invention, an electromagnetic wave generator formed of a conductive material is disposed in the vicinity of the fuel to be processed in a non-contact state with the fuel to be processed, and a power supply device is connected to the electromagnetic wave generator. Then, a voltage of 800 to 30000 V may be applied with an alternating current, and the generated electromagnetic wave may be irradiated to the water to be treated.
