Description

  The present invention relates to a brown gas generation system.

  A mixed gas of hydrogen and oxygen in which hydrogen and oxygen are mixed at a mixing ratio of 2 to 1 has been studied for use in various fields as pollution-free energy. In particular, it is attracting attention as a fuel for automobile engines. Such a mixed gas of hydrogen and oxygen is also called a brown gas. Hereinafter, in this specification, such a mixed gas is referred to as a brown gas.

  As a device for generating brown gas, a brown gas generating device using plasma and a brown generating device using electrolysis are known. However, a brown gas generating device using plasma is a large-scale device and consumes power. Is extremely unsuitable for use as a fuel generator for automobile engines (hereinafter referred to as a fuel generator for automobiles). For this reason, a brown gas generator utilizing electrolysis is suitable for use as a fuel generator for automobiles. Various brown devices using electrolysis have been conventionally proposed (see, for example, Patent Document 1 and Non-Patent Document 1).

  Patent Document 1 describes a brown gas generator using electrolysis. Non-Patent Document 1 describes an example in which a brown gas generator using electrolysis is incorporated in an automobile and used as a fuel generator for an automobile.

Water Hybrid; Hydrogen-on-Demand System Using water as fuel [Search July 8, 2010] Internet <URL: http // www.unique-shohin.com / water2car.htm>

  As described above, various brown gas generators utilizing electrolysis have been proposed, and mounting the brown gas generator as an automobile combustion generator in an automobile has been carried out experimentally, but is still in progress. It has not been put into practical use.

  The reason why the brown gas generator cannot be put into practical use as a combustion generator for automobiles is that various problems remain in using the brown gas generator as a fuel generator for automobiles. For example, electrodes (positive and negative electrodes) that are immersed in the electrolytic solution in the electrolytic cell are subject to severe deterioration due to electrical contact and become unusable in a short period of time, and it is appropriate to control the current flowing in the electrolytic solution. In other words, more current than necessary flows, the temperature rise of the electrolyte does not stop, the pressure inside the electrolytic cell storing the electrolytic solution increases, and the electrolytic cell eventually breaks down There are many issues that must be solved, such as issues. For these reasons, the brown gas generator has not been put into practical use as a fuel generator for automobiles.

  Such a problem is not a problem that exists only when the brown gas generator is put into practical use as a combustion generator for automobiles, but is put into practical use as a combustion generator for use in vehicles other than automobiles. In this case, when the brown gas generator is put into practical use as a fuel generator used for a ship, the brown gas generator is also a problem that exists when the brown gas generator is put into practical use as a fuel generator used for other purposes.

  Therefore, an object of the present invention is to provide a brown gas generation system that can be put to practical use as a fuel generation device.

[1] A brown gas generation system of the present invention includes an electrolytic tank that stores an electrolytic solution mainly composed of water, and a positive electrode and a negative electrode that are provided so as to be immersed in the electrolytic solution and have electric resistance. A brown lid that seals the upper end opening of the electrolytic cell and generates a brown gas by electrolyzing the electrolytic solution by flowing a current from the positive electrode to the negative electrode using a power supply device The apparatus includes a gas generator and a current control unit that controls a value of a current flowing from the positive electrode to the negative electrode to a predetermined value.

  Thus, in the Brown gas generation system of the present invention, the positive electrode and the negative electrode have electric resistance. Therefore, according to the brown gas generation system of the present invention, it is possible to solve the problem of the conventional brown gas generation device, that is, "the problem that the deterioration due to electrical contact is severe and the use becomes impossible in a short period of time". it can.

  Moreover, the brown gas generation system of the present invention includes a current control unit that controls the current value to a predetermined value. For this reason, according to the brown gas generation system of the present invention, another problem of the conventional brown gas generation device, that is, “the current more than necessary flows and the temperature rise of the electrolyte does not stop, The problem that the internal pressure of the electrolytic cell storing the liquid increases and the electrolytic cell is destroyed can be solved.

  Thus, according to the brown gas generation system of the present invention, the above two problems of the conventional brown gas generation device can be solved. Therefore, the brown gas generation system of the present invention can be put into practical use as a fuel generation device used for vehicles, ships, and other applications.

  According to the brown gas generation system of the present invention, a remarkable effect can be obtained only by mixing a relatively small amount of brown gas with fuel. For example, when the brown gas generation system of the present invention is applied to a 1500 cc class automobile, a few bubbles are generated per second from the brown gas generation system of the present invention, and these bubbles are mixed with fuel such as gasoline. As will be described later, a significantly large fuel efficiency improvement effect (for example, an improvement of 50% or more) and a significant harmful gas reduction effect (for example, a reduction of 80% or more) can be obtained.

  In the Brown gas generation system of the present invention, the “predetermined value” includes “predetermined range (for example, 4.5 amperes to 5.5 amperes)” in addition to “constant value (for example, 5 amperes)”. Shall.

[2] In the brown gas generation system of the present invention, the predetermined value is preferably in a range of 2 to 7 amperes.

In this way, stable electrolysis can be achieved by controlling the value of the current flowing from the positive electrode to the negative electrode to a predetermined value within the range of 2 to 7 amperes. According to the experiment, when the value of the current flowing from the positive electrode to the negative electrode is less than 2 amperes, the electrolysis becomes insufficient, and the value of the current flowing from the positive electrode to the negative electrode exceeds 7 amperes It was confirmed that electrolysis was excessive and the temperature of the electrolyte became too high.
In the brown gas generation system of the present invention, it was confirmed that particularly good results were obtained when the predetermined value was 4.5 amperes to 5.5 amperes.

[3] In the brown gas generation system of the present invention, it is preferable that titanium is used for each of the positive electrode and the negative electrode, and that the positive electrode is precious metal plated on a titanium material.

  Thus, a titanium material is used for each of the positive electrode and the negative electrode, and the noble metal plating is further applied to the positive electrode, whereby an electrode having excellent electric resistance can be obtained. Thereby, it can suppress that a positive electrode and a negative electrode deteriorate by electric contact, and can be set as the electrode which can endure long-term use. Thereby, the durability of the brown gas generator of the present invention can be improved.

[4] The brown gas generation system of the present invention preferably further includes a temperature control unit that controls the temperature of the electrolytic solution so that the temperature of the electrolytic solution does not exceed a preset temperature.

  This is to enable control of the temperature of the electrolytic solution itself in addition to the suppression of abnormal temperature rise by current control. That is, in the Brown gas generation system of the present invention, double measures are taken to prevent the temperature of the electrolyte from rising abnormally. Thus, according to the brown gas generation system of the present invention, it is possible to reliably prevent the temperature of the electrolyte from rising abnormally.

[5] In the brown gas generation system of the present invention, the temperature control unit cuts off a current flowing from the positive electrode to the negative electrode when the temperature of the electrolyte rises to a first set temperature, and in this state It is preferable to control the temperature of the electrolytic solution by causing a current to flow again from the positive electrode to the negative electrode when the temperature of the electrolytic solution decreases to a second set temperature lower than the first set temperature.

  By setting it as such a structure, it becomes possible to prevent reliably that the temperature of electrolyte solution becomes temperature higher than 1st preset temperature.

[6] In the brown gas generation system of the present invention, it is preferable that the first set temperature is in a range of 65 ° C to 75 ° C, and the second set temperature is in a range of 45 ° C to 55 ° C.

  Thus, since the first set temperature is in the range of 65 ° C. to 75 ° C., it is possible to reliably prevent the temperature of the electrolytic solution from becoming higher than 65 ° C. to 75 ° C. In addition, since the second set temperature is in the range of 45 ° C. to 55 ° C. in this way, it is possible to resume the electrolysis as soon as the temperature drops slightly.

[7] In the brown gas generation system of the present invention, the positive electrode is composed of one plate-shaped metal plate, the negative electrode is composed of two plate-shaped metal plates, and the positive electrode The negative electrode is preferably arranged so that the two negative electrodes are opposed to the positive electrode at a predetermined interval with respect to the positive electrode with the positive electrode as a center.

  By configuring the positive electrode and the negative electrode as described above, efficient electrolysis can be performed with a simple configuration.

[8] In the brown gas generating system of the present invention, it is preferable that the brown gas generating device has a pressure adjusting unit that adjusts the pressure inside the electrolytic cell in accordance with a change in atmospheric pressure.

  By providing such a pressure adjusting unit, the pressure in the electrolytic cell can be maintained at an appropriate pressure. Thereby, even when the brown gas generation system of the present invention is used in a place where the altitude is high and the atmospheric pressure is low, the pressure in the electrolytic cell can be maintained at an appropriate pressure.

[9] In the brown gas generation system of the present invention, it is preferable that the electrolytic cell is made of metal and the sealing lid is made of a synthetic resin.

  By adopting such a configuration, if it is assumed that the pressure in the electrolytic cell is abnormally high for some reason and the electrolytic cell is ruptured, only the sealing lid that is lower in strength than the electrolytic cell is used. If is destroyed, loss due to destruction can be reduced. That is, if the entire electrolytic cell including the sealing lid is made of metal (for example, stainless steel), there is no risk of rupture force escape and there is a risk that the destructive force will be greater. Only the breakage of the sealing lid is required, and the loss due to destruction can be kept small.

[10] In the Brown gas generation system of the present invention, the electrolytic solution is obtained by dissolving sodium carbonate or sodium bicarbonate in water, and the weight ratio of the sodium carbonate or sodium bicarbonate to the water is 2 It is preferable that it exists in the range of% -40%.

  Electrolysis can be accelerated | stimulated because electrolyte solution is comprised with such a component. There are other substances that promote electrolysis, but sodium carbonate or sodium hydrogen carbonate is advantageous in that it is inexpensive and easily available with high safety.

[11] In the brown gas generation system of the present invention, the electrolytic solution is preferably stored in the electrolytic cell in a state where carbonic acid content is removed.

  This is because if carbonic acid is present, the carbonic acid contaminates the electrodes (positive electrode and negative electrode) and adversely affects the electrodes. The state in which the carbonic acid content is removed can be formed by heating the electrolytic solution.

[12] In the brown gas generation system of the present invention, the brown gas generator has an electrolyte replenishment mechanism capable of automatically replenishing the electrolyte when the electrolyte stored in the electrolytic cell decreases. Furthermore, it is preferable to have.

  By providing such an electrolytic solution replenishment mechanism, when the electrolytic solution in the electrolytic cell is reduced, the electrolytic solution is automatically dropped and replenished, so that the electrolytic solution in the electrolytic cell can always be maintained at an appropriate level. it can. This eliminates the need for the user to worry about the amount of electrolyte in the electrolytic cell.

  [13] In the brown gas generation system according to the present invention, the brown gas generation system is mounted on a vehicle, and the brown gas generation device includes the “carburetor” or “electronic fuel injection” of the vehicle. It is preferable to be configured to be connectable to the “air intake port of the apparatus”.

  By setting it as such a structure, the brown gas generation system of this invention can be used as a fuel generator for vehicle engines, such as a motor vehicle engine. That is, the brown gas discharge port provided in the brown gas generation device in the brown gas generation system of the present invention is connected to the air intake port of the carburetor or electronic fuel injection device originally mounted on the vehicle, and the brown gas discharge port is connected. Brown gas discharged from the outlet burns in the engine together with atomized fuel such as gasoline. Thus, by burning brown gas together with atomized fuel such as gasoline, fuel efficiency can be improved and harmful exhaust gas emissions can be reduced.

  [14] In the brown gas generation system of the present invention, the power supply device is preferably a storage battery mounted on the vehicle.

  As described above, since the storage battery (battery) originally mounted on the vehicle such as an automobile can be used as the power supply device of the brown gas generation system of the present invention, the power supply device dedicated to the brown gas generation system is not required. When the gas generation system is mounted on an automobile, it can be mounted at low cost, and the installation space can be kept small.

1 is a diagram illustrating a configuration of a brown gas generation system 10 according to Embodiment 1. FIG. It is a figure shown in order to demonstrate the inside of the electrolytic vessel 101 in the brown gas generator 100. FIG. It is a perspective view which takes out and shows the positive electrode 109 and the negative electrodes 110 and 111. It is a figure which shows typically the case where the brown gas generation system 10 which concerns on Embodiment 1 is mounted in a motor vehicle. It is a figure shown in order to demonstrate the brown gas generator 100 in the brown gas generation system 20 which concerns on Embodiment 2. FIG.

  Hereinafter, embodiments of the present invention will be described.

[Embodiment 1]
FIG. 1 is a diagram illustrating a configuration of a brown gas generation system 10 according to the first embodiment. As shown in FIG. 1, the brown gas generation system 10 according to the first embodiment includes a brown gas generation device 100, a current control unit 200 that controls the value of current applied to the brown gas generation device 100 to a predetermined range, and brown gas It has a temperature control unit 300 that controls the temperature of the electrolytic solution 108 (see FIG. 2) in the generator 100 so as not to exceed a set temperature, and a power supply device 400 as a DC power supply.

  The brown gas generator 100 has an exterior configuration in which an electrolytic cell 101 that stores an electrolytic solution 108 (see FIG. 2) containing water (pure water) as a main component and an upper end opening of the electrolytic cell 101 are hermetically sealed. The lid 102, the positive electrode terminal 103 and the negative electrode terminal 104, the electrolytic solution supply port 105 for supplying the electrolytic solution 108 (see FIG. 2) into the electrolytic cell 101, and the electrolytic solution supply port 105 can be opened and closed. A cap 105a, a pressure adjusting unit 106 that adjusts the pressure in the electrolytic cell 101 in response to a change in atmospheric pressure due to a difference in altitude, and a brown gas discharge port 107 that discharges brown gas generated by electrolysis are provided. Yes. The pressure adjustment unit 106, the positive electrode terminal 103 and the negative electrode terminal 104, the electrolyte supply port 105, and the brown gas discharge port 107 are provided in the sealing lid 102.

  The brown gas generator 100 configured in this way looks large in FIG. 1, but as an actual device, the x-axis direction is about 70 mm, the y-axis direction is about 150 mm, and the z-axis direction is about 170 mm. is there. For this reason, when the brown gas generator 100 is mounted in the engine room of an automobile, it can be sufficiently mounted even in a small car. Further, since the current control unit 200 is also small, there is no problem in terms of installation space.

  The sealing lid 102 is made of a transparent synthetic resin. In addition, although it is not essential that the synthetic resin is transparent, it is more preferable that it is transparent because the inside of the electrolytic cell 101 can be visually observed. Further, the reason that the sealing lid 102 is made of synthetic resin is that the electrolytic cell 101 is assumed to have a case where the pressure inside the electrolytic cell 101 becomes abnormally high for some reason and the electrolytic cell 101 bursts. This is because if only the sealing lid 102 having a low strength is destroyed, the loss due to the destruction can be suppressed to a small value. That is, if the entire electrolytic cell 101 including the sealing lid 102 is made of a metal (for example, stainless steel), there is no possibility of a breaching force escape and the breaking force may be increased. If this is the case, only the sealing lid 102 needs to be broken, and loss due to destruction can be kept small.

  Further, the pressure adjusting unit 106 adjusts the pressure in the electrolytic cell 101 in response to the change in atmospheric pressure, and maintains the pressure in the electrolytic cell 101 at an appropriate pressure. For example, in a place where the altitude is high and the atmospheric pressure is low, it operates so as to release the pressure in the electrolytic cell 101. Further, not only the difference in altitude, but also when the pressure in the electrolytic cell 101 becomes high for some reason, it operates so as to release the pressure in the electrolytic cell 101. Thereby, the pressure in the electrolytic cell 101 can be maintained at an appropriate pressure.

  The current control unit 200 controls the value of the current flowing from the positive electrode 109 to the negative electrodes 110 and 111 (see FIG. 2) to a predetermined value (for example, 5 amperes). Thus, the reason why the value of the current flowing from the positive electrode 109 to the negative electrodes 110 and 111b is controlled to a predetermined value (for example, 5 amperes) is to enable stable electrolysis. According to the experiment, when the predetermined value is less than 2 amperes, the electrolysis is insufficient, and when the predetermined value is greater than 7 amperes, the electrolysis is excessive. It was confirmed that the temperature of the electrolyte became too high.

  When the automobile power supply apparatus 400 is a power supply apparatus having a current supply capacity of 15 amperes, for example, the current control unit 200 determines the value of the current flowing from the positive electrode 109 to the negative electrodes 110 and 111 as the automobile power supply apparatus 400. Is controlled to a predetermined value (for example, 5 amperes) lower than the current supply capability (15 amperes).

  The temperature controller 300 is a thermostat that controls the temperature of the electrolytic solution 108 (see FIG. 2) stored in the electrolytic cell 101. That is, when the temperature of the electrolyte 108 rises to the first set temperature, the current flowing from the positive electrode 109 to the negative electrodes 110 and 111 is cut off, and then the second set temperature where the temperature of the electrolyte 108 is lower than the first set temperature. When the voltage drops to, the current of the positive electrode 109 is passed through the negative electrodes 110 and 111 again to control the temperature of the electrolyte. The first preset temperature is preferably in the range of 65 ° C. to 75 ° C. In the brown gas generation system 10 according to Embodiment 1, the first preset temperature is 70 ° C. The second set temperature is preferably in the range of 45 ° C. to 55 ° C. In the brown gas generation system 10 according to Embodiment 1, the second set temperature is set to 50 ° C.

  By having such a temperature control unit 300, it is possible to reliably prevent the temperature of the electrolytic solution 108 from becoming higher than 70 ° C.

  The temperature control of the electrolytic solution 108 can also be performed by current control by the current control unit 200 (control to maintain the current value at 5 amperes), but in addition to temperature control by current control, the temperature of the electrolytic solution 108 is controlled. By also controlling itself, it is possible to reliably prevent the temperature of the electrolytic solution 108 from rising abnormally. That is, in the brown gas generation system 10 according to the first embodiment, double measures are taken to prevent the temperature of the electrolyte solution 108 from rising abnormally. Thus, according to the brown gas generation system 10 according to the first embodiment, it is possible to reliably prevent the temperature of the electrolytic solution 108 from rising abnormally.

  FIG. 2 is a view for explaining the inside of the electrolytic cell 101 in the brown gas generator 100. 2 is a cross-sectional view taken along line AA in FIG. In FIG. 2, the same components as those in FIG. 1 are denoted by the same reference numerals.

  FIG. 3 is a perspective view showing the positive electrode 109 and the negative electrodes 110 and 111 taken out. The positive electrode 109 and the negative electrodes 110 and 111 will be described in detail with reference to FIGS. Inside the electrolytic bath 101, there are provided one positive electrode 109 and two negative electrodes 110, 111 immersed in the electrolytic solution 108 (see FIG. 2).

  Further, each of the positive electrode 109 and the negative electrodes 110 and 111 is a plate-like electrode (see FIG. 3), and an electric-resistant member is used as the material thereof. A titanium material is used as a member having electric resistance, and the positive electrode 109 is further subjected to platinum plating on the surface of the titanium material. Thus, titanium materials are used for the positive electrode 109 and the negative electrodes 110 and 111, respectively, and the surface of the positive electrode 109 is further precious metal plated, so that the electrode has excellent electric resistance. be able to. Thereby, it can suppress that the positive electrode 109 and the negative electrodes 110 and 111 deteriorate by electric contact, and it can be set as the electrode which can endure long-term use. Examples of the noble metal plating include platinum plating, iridium plating, and platinum / iridium alloy plating.

  Further, as shown in FIGS. 2 and 3, the positive electrode 109 and the negative electrodes 110 and 111 are arranged such that the two negative electrodes 110 and 111 are spaced apart from the positive electrode 109 with the positive electrode 109 as the center. And arranged opposite to the positive electrode 109 in parallel. By arranging the positive electrode 109 and the negative electrodes 110 and 111 in this way, efficient electrolysis can be performed with a simple configuration.

  As shown in FIG. 3, the positive electrode 109 has a horizontal protrusion 109a on the upper end side, and a bolt through hole 109b is provided in the horizontal protrusion 109a. The positive electrode 109 configured in this manner is passed through the bolt through hole 109b by passing a bolt 121 (see FIG. 2) and tightening a nut 122 (see FIG. 2) on the surface side of the sealing lid 102, thereby Can be attached. The bolt 121 and the nut 122 also serve as the positive electrode terminal 103.

  On the other hand, as shown in FIG. 3, the negative electrodes 110 and 111 have horizontal protrusions 110a and 111a on their upper ends, respectively, and these horizontal protrusions 110a and 111a are provided with bolt through holes 110b and 111b, respectively. It has been. In addition, the bolt through-hole 111b of the horizontal protrusion part 111a in the negative electrode 111 exists in the position which cannot be visually observed in FIG.

  The negative electrodes 110 and 111 configured in this way are arranged such that the bolt through holes 110b of the horizontal protrusions 110a in the negative electrode 110 and the bolt through holes 111b of the horizontal protrusions 111a in the negative electrode 111 coincide with each other. With the horizontal protrusions 110a and 111a overlapped, the nut 124 (see FIG. 2) is tightened on the surface side of the sealing lid 102 by passing the bolt 123 (see FIG. 2) through the bolt through holes 110b and 111b. The electrodes 110 and 111 can be attached to the sealing lid 102. The bolt 123 and the nut 124 also serve as the negative electrode terminal 104.

  Further, the lower end side of the positive electrode 109 and the lower end side of the negative electrodes 110 and 111 are supported in a state in which movement is restricted by an electrode support member 112 (see FIG. 2) made of an insulating member such as a synthetic resin. ing. The electrode support member 112 has a convex portion 112a on its lower end side, and the movement of the convex portion 112a is regulated by positioning projections 101a and 101b (see FIG. 2) provided on the lower end surface of the electrolytic cell 101. ing. Because of such a configuration, the positive electrode 109 and the negative electrodes 110 and 111 are appropriately maintained in the interval between the electrodes and in a parallel state, and are held at appropriate positions in the electrolytic cell 101.

  Further, as the electrolytic solution 108, a solution obtained by dissolving a predetermined amount of sodium carbonate in water (distilled water) is used. In addition, although it is preferable that sodium carbonate is set to about 2% in a weight ratio with respect to water, it may be 2% or more, and the upper limit is about 40%.

  Electrolysis can be accelerated | stimulated because the electrolyte solution 108 is comprised with such a component. There are other substances that promote electrolysis, but sodium carbonate is advantageous in that it is inexpensive and easily available with high safety.

  Further, the electrolytic solution 108 is preferably stored in the electrolytic cell 101 in a state where the carbonic acid content is removed. This is because if carbonic acid is present, the carbonic acid pollutes the electrodes (the positive electrode 109 and the negative electrodes 110 and 111) and adversely affects the electrodes. The state in which the carbonic acid content is removed can be formed by heating the electrolytic solution.

  Further, when the Brown gas generation system 10 according to Embodiment 1 can be used in a cold region, it is preferable to mix a predetermined amount of, for example, ethylene glycol or the like as an antifreezing agent into the electrolytic solution 108. The amount of the antifreezing agent is appropriately set according to the minimum temperature in each region.

  In the brown gas generation system 10 according to the first embodiment configured as described above, the current from the power supply device 400 is limited to 5 amperes by the current control unit 200 and the two negative electrodes 110 and 111 from the positive electrode 109. Flowing into. As a result, electrolysis of the electrolytic solution 108 occurs and brown gas is generated. The generated brown gas is discharged from the brown gas discharge port 107. In FIG. 1, the brown gas discharge port 107 is not connected anywhere. Actually, the brown gas discharge port 107 is a car carburetor or an electronically controlled fuel injection device. The brown gas discharged from the brown gas outlet 107 is sent to the air inlet of the carburetor or the electronically controlled fuel injection device.

  FIG. 4 is a diagram schematically illustrating a case where the brown gas generation system 10 according to the first embodiment is mounted on an automobile. In the case where the Brown gas generation system 10 according to the first embodiment (hereinafter referred to as “Brown gas generation system 10”) is mounted on a vehicle, the power supply device 400 is a storage battery (battery) originally mounted on the vehicle. Can be used. Here, it is assumed that the power supply device 400 is a general storage battery of 12 volts. In this case, a 15-ampere fuse 500 for automobiles is interposed between the plus (+) side terminal of the power supply device 400 and the current control unit 200.

  Further, the brown gas discharge port 107 provided in the brown gas generator 100 is connected to an air intake port of a carburetor or an electronically controlled fuel injection device (herein described as a carburetor 520) by a brown gas supply pipe 510. ing. Specifically, the brown gas supply pipe 510 is connected to an air supply pipe 540 connecting the air cleaner 530 of the automobile and the air intake port of the carburetor 520.

  Further, a switch (not shown) for starting the brown gas generation system 10 is interlocked with an ignition switch (not shown) of the automobile. As a result, when the ignition switch of the automobile is turned on and the engine is started, the brown gas generation system 10 is also started. That is, while the engine is operating, electrolysis occurs and brown gas is generated. The generated brown gas is supplied from the brown gas outlet 107 through the brown gas supply pipe 510 to the carburetor 520. The fuel is supplied to an engine (not shown) together with the atomized gasoline.

  When the brown gas generation system 10 is mounted on an automobile as shown in FIG. 4, it is preferable to set the ignition timing of the engine to be slightly earlier than usual. This is because, when brown gas with a large combustion energy is mixed in atomized gasoline, the engine operates more efficiently and generates more power if it is ignited slightly earlier than the normal ignition timing. Because it can be created.

  It has been found that when the brown gas generation system 10 is mounted on an automobile as shown in FIG. 4, various advantages can be obtained compared to the case where the brown gas generation system 10 is not mounted. This will be described below.

  Here, an automobile with a displacement of 1300 cc (referred to as a first measurement vehicle) and an 1800 cc automobile (referred to as a second measurement vehicle) in a certain automobile manufacturer (referred to as company A) and another automobile manufacturer ( The case where the Brown gas generation system 10 is not mounted and the case where the Brown gas generation system 10 is mounted using an automobile (referred to as a third measurement vehicle) having a displacement of 1000 cc. For both, the measurement results of fuel consumption and exhaust gas will be described.

  Note that the three automobiles (first to third measurement vehicles) used in this experiment are automobiles equipped with a gasoline engine (referred to as gasoline cars). Hereinafter, a state in which the brown gas generation system 10 is not mounted is referred to as “no brown gas generation system mounted”, and a state in which the brown gas generation system 10 is mounted is referred to as “brown gas generation system mounted”. . In the case of “with brown gas generation system”, it is a matter of course that brown gas is being supplied to the engine.

  First, the average fuel consumption when running in urban areas and traveling over long distances (total of 200 km or more) using the first measurement vehicle with “Brown gas generation system not installed” is “11.1 km” per liter of gasoline. Met. On the other hand, the average fuel consumption when running in urban areas and traveling long distances (cumulative total of 300 km or more) using the first measurement vehicle with “Brown Gas Generation System” is “ 18.8 km ". Thus, in the first vehicle for measurement, the fuel efficiency was improved by approximately 69% in the case of “equipped with a brown gas generation system” as compared with the case of “not equipped with a brown gas generation system”.

  In addition, as a result of measuring the emission concentration of carbon monoxide (CO) and hydrocarbon (HC) into the atmosphere using the first measurement vehicle with “Brown gas generation system not installed”, CO is “0. 35 vol% "and HC were" 289 ppm ".
