Description

  The present invention relates to an apparatus for producing an HHO gas fine bubble mixed fuel for producing a mixed fuel in which fine bubbles of HHO gas are dispersed in a liquid fuel such as light oil, heavy oil or gasoline supplied to an internal combustion engine or a combustion apparatus.

  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 has attracted attention as a fuel for internal combustion engines such as automobile engines. Such a mixed gas of hydrogen and oxygen is called HHO gas or Brown gas. Hereinafter, in this specification, such a mixed gas is referred to as HHO gas.

  As an apparatus for generating HHO gas, an HHO gas generator using plasma or an HHO gas generator using electrolysis is known. Since HHO gas is a combustible gas, it has been proposed to use it as a fuel for combustion apparatuses such as internal combustion engines such as automobile engines and burners. For example, in Japanese Patent Application Laid-Open No. 10-266900 (Patent Document 1) and Japanese Patent Application Laid-Open No. 10-220237 (Patent Document 2), an HHO gas generated by an HHO gas generator is supplied as a fuel to an internal combustion engine. An example of driving is described.

  However, a large amount of HHO gas is required in order to use HHO gas as a fuel for automobile engines and as an alternative fuel such as gasoline or light oil that is generally used. For this reason, a large HHO gas generator is inevitably required, but it is difficult to mount a large HHO gas generator in an automobile, and a large amount of power is required. This battery has not yet been put into practical use because it has insufficient capacity and cannot obtain sufficient power from a car generator.

  Against this background, the applicant of the present application disclosed in Japanese Patent Application No. 2010-173234 (Patent Document 3) a fuel obtained by mixing a relatively small amount of HHO gas into an automobile engine driven by fuel such as gasoline or light oil. It was proposed to promote complete combustion by accelerating or assisting combustion. Such a hybrid combustion system provides a significant fuel efficiency improvement effect of 30% to 70%, and in addition to carbon monoxide (CO) and hydrocarbons (HC), sulfur oxide (SOx), Nitrogen oxide (NOx) has been confirmed to be greatly reduced, and is now being put into practical use.

JP-A-10-266900 Japanese Patent Laid-Open No. 10-220237 Japanese Patent Application No. 2010-173234

  However, the above-described hybrid combustion system has been improved by, for example, modifying the intake port of the automobile engine to add HHO gas to the automobile engine, and the HHO gas delivered from the HHO gas generator. Therefore, there is a problem that advanced skills are required to improve the engine for automobiles. On the other hand, in the case of a large ship engine, a relatively large amount of HHO gas is required. Therefore, the HHO gas generator is inevitably enlarged, which requires a large installation space and a high installation cost. There is a problem to become.

  The problem to be solved by the present invention is that the fuel in the fuel tank can be supplied to the engine as a mixed fuel in which fine bubbles of HHO gas are dispersed, and the engine is additionally processed by using this mixed fuel. An object of the present invention is to provide an apparatus for producing an HHO gas fine bubble mixed fuel that has high combustion efficiency and can improve fuel efficiency.

  Therefore, an apparatus for producing HHO gas fine bubble mixed fuel according to the present invention includes an HHO gas generator for generating HHO gas from an electrolyte mainly composed of water, and light oil, heavy oil for supplying to an internal combustion engine or a combustion apparatus, or A fuel tank that stores liquid fuel such as gasoline; a microbubble generator that generates microbubbles of micro or nano bubbles; and a fuel flow path that communicates the microbubble generator with the fuel tank. The HHO gas of the HHO gas generator and the liquid fuel of the fuel tank are introduced into the generator to generate a mixed fuel in which fine bubbles of the HHO gas are dispersed in the liquid fuel, and the fuel flow path Through which the mixed fuel is introduced into the fuel tank and the liquid fuel in the fuel tank is introduced into the microbubble generator. That.

  The HHO gas generator includes an electrolytic cell that stores an electrolytic solution mainly composed of water, a plurality of sets of electrodes including an anode and a cathode, and a sealing lid that seals an upper end of the electrolytic cell. An electrolysis device that generates HHO gas by electrolysis by flowing current between the plurality of sets of anodes and cathodes using a power supply device, and a current that flows between the anode and cathode of each electrode. A current control device for controlling to a predetermined current value is provided, and the HHO gas is introduced into the fine bubble generating device from a discharge port provided with a sealing lid.

  Furthermore, the internal combustion engine and the combustion apparatus are configured to supply the mixed fuel from a fuel supply path connected to one end of the fuel flow path that allows the fine bubble generating device and the fuel tank to communicate with each other.

  The internal combustion engine and the combustion apparatus supply the mixed fuel from the discharge side of the fine bubble generator and the fuel tank in the fuel flow path.

  According to the present invention, the HHO gas generated from the HHO gas generator generates microbubbles of micro or nanobubble HHO gas by the microbubble generator, and the liquid fuel in the fuel tank is changed to HHO gas microbubbles. Since the circulation flow path generated in the dispersed mixed fuel is formed, the liquid fuel in the fuel tank can be brought into the mixed fuel state. By using this mixed fuel as a fuel for an internal combustion engine such as an automobile or marine engine or a combustion device such as a burner, the HHO gas that has become fine bubbles in the combustion of the internal combustion engine or the combustion device accelerates the combustion of the liquid fuel or By assisting, complete combustion is promoted, so that a remarkable fuel efficiency improvement effect can be obtained. In addition to carbon monoxide (CO) and hydrocarbons (HC), sulfur oxides (SOx) and nitrogen oxides (NOx) can be greatly reduced.

  Moreover, since the HHO gas generator has a plurality of sets of electrodes, a large amount of HHO gas can be stably generated. Moreover, since a current control device that controls the current flowing between the anode and the cathode in each electrode to a predetermined current value is provided, the current value in each electrode is appropriately controlled. It is possible to prevent an increase in the temperature of the electrolytic solution due to flowing. By introducing the HHO gas generated stably from this HHO gas generator into the microbubble generator, microbubbles of micro or nanobubble HHO gas are stably generated, so liquid fuel in the fuel tank is always mixed It becomes possible to make the fuel state.

  Further, the internal combustion engine and the combustion device supply liquid fuel in the fuel tank to the HHO gas by supplying mixed fuel from a fuel supply path connected to one end of a fuel flow path that connects the fine bubble generating device and the fuel tank. In parallel with the mixed fuel in which the fine bubbles are dispersed, the mixed fuel can be supplied to the internal combustion engine and the combustion apparatus. For this reason, even if at least one of the HHO gas generator and the fine bubble generator fails, the liquid fuel in the fuel tank can be supplied to the internal combustion engine and the combustion device. And the combustion apparatus can be operated.

  Furthermore, when the internal combustion engine or the combustion apparatus is started by supplying the mixed fuel from the discharge side of the fine bubble generator and the fuel tank in the fuel flow path, for example, in the fuel tank. Even when the remaining amount of the fine bubbles of the HHO gas is small in the liquid fuel, the mixed fuel is supplied promptly from the fine bubble generating device, so that it is possible to obtain an improvement in fuel consumption from the start.

It is a block diagram which shows the other Example of the manufacturing apparatus of the HHO gas fine bubble mixed fuel concerning this invention. It is a block diagram which shows the Example which applied the manufacturing apparatus of the HHO gas fine bubble mixed fuel concerning this invention to the combustion apparatus.

  The HHO gas microbubble mixed fuel manufacturing apparatus includes an HHO gas generator that generates HHO gas from an electrolyte mainly composed of water, and a liquid fuel such as light oil, heavy oil, or gasoline to be supplied to an internal combustion engine or a combustion apparatus. A fuel tank for storing the microbubbles, a microbubble generator for generating microbubbles or nanobubbles, and a circulation flow path for communicating the microbubble generator with the fuel tank. The fine bubble generator introduces the HHO gas generated by the HHO gas generator and the liquid fuel in the fuel tank, and generates a mixed fuel in which the fine bubbles of the HHO gas are dispersed in the liquid fuel. A circulation channel is formed between the fuel tank and the fine bubble generating device, and after the liquid fuel in the fuel tank is introduced into the fine bubble generating device, the mixed fuel generated by the fine bubble generating device is supplied to the fuel tank. It is circulated so as to be introduced again into the microbubble generator.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows an example in which an apparatus for producing HHO gas fine bubble mixed fuel is applied to, for example, a diesel engine as an internal combustion engine.

  First, the manufacturing apparatus of the HHO gas fine bubble mixed fuel will be described. The HHO gas microbubble mixed fuel manufacturing apparatus includes an HHO gas generator 1 that generates HHO gas, a fuel tank 2 that stores liquid fuel to be supplied to an internal combustion engine and a combustion device, and micro or nanobubble microbubbles. The generated fine bubble generating device 3 and the fuel flow path 4 for communicating the fine bubble generating device 3 and the fuel tank 2 are provided. In the case of an internal combustion engine such as an automobile or a ship, the fuel tank 2 is a fuel tank provided in the automobile or the ship to store gasoline, light oil or the like supplied to the engine, and is a combustion device such as a burner. If there is, it is a fuel tank provided in a combustion device or the like for storing heavy oil or the like as fuel. The fuel tank 2 is provided with a fuel filler port 2a for containing fuel and a vent port 2b for discharging a small amount of HHO gas leached from the mixed fuel described later. The vent 2b may be a general one provided to discharge gas evaporated from normal liquid fuel to the outside.

  As shown in FIG. 2, the HHO gas generator 1 that generates the HHO gas has a predetermined current value so that the current flowing between the electrolyzer 100 and the anode and cathode of each electrode of the electrolyzer 100 becomes a predetermined current value. A current control device 110 that controls the power supply, and a power supply device 120 as a DC power supply.

  The electrolyzer 100 includes an electrolytic cell 101 that stores an electrolyte mainly composed of water (pure water), a sealing lid 102 that seals the upper end opening of the electrolytic cell 101, and an anode and a cathode. Anode-side electrode terminals 104a for supplying power to each of a plurality of sets of electrodes (for example, only the electrode 103 is shown in FIG. 2 and the other two sets of electrodes are not shown), 104b, 104c and cathode side electrode terminals 105a, 105b, 105c, and an HHO gas discharge nozzle 106 for discharging HHO gas generated by electrolysis. Although not shown, the sealing lid 102 is provided with an electrolytic solution supply port for supplying the electrolytic solution 107 into the electrolytic cell 101. In addition, a pressure adjusting unit that adjusts the pressure in the electrolytic cell 101 in response to a change in atmospheric pressure due to a difference in altitude or the like is provided as necessary. The pressure adjusting unit operates not only to change the altitude but also to release the pressure in the electrolytic cell 101 even when the pressure in the electrolytic cell 101 becomes high for some reason. It also has a function of maintaining the pressure at an appropriate pressure.

  The electrolytic cell 101 is made of a reinforced synthetic resin, and the sealing lid 102 is made of a synthetic resin that is lower in strength than the electrolytic cell 101. As described above, the reason why the sealing lid 102 is a synthetic tree that is lower in strength than the electrolytic cell 101 is that the internal pressure of the electrolytic cell 101 becomes abnormally high for some reason and the electrolytic cell 101 bursts. In such a case, only the sealing lid 102 that is lower in strength than the electrolytic cell 101 is destroyed, so that the electrolyte solution is prevented from flowing out due to the destruction and the loss can be minimized.

  In addition, a partition plate 108 formed of a plate member made of synthetic resin or the like is provided between two adjacent electrodes. The partition plate 108 is installed in the electrolytic cell 101 with its lower end side in close contact with the inner bottom surface of the electrolytic cell 101 and both side edges in close contact with the internal side surface of the electrolytic cell 101. In addition, the height of the upper end side of the partition plate 108 is set slightly higher than the height of the electrode 103, and the upper end side of the partition plate 180 and the inner surface of the sealing lid 102 are communicated with each other. Thus, by providing the partition plates 108 between the electrodes, even when the electrolytic cell 101 is slightly inclined, the electrolyte solution 101 is horizontal in each partition chamber, and the specific electrode is the liquid level of the electrolyte solution 101. Can be prevented from being exposed.

  The anode and the cathode of the electrode 103 are composed of one anode plate 103a and two cathode plates 103b, and the two cathode plates 103b are sandwiched between the anode plates 103a at a predetermined interval. So as to face each other. The anode plate 103 a and the two cathode plates 103 b are supported in a state in which the lower end side is restricted in movement to the inner bottom surface of the electrolytic cell 101. Further, one anode plate 103a is fixed by attaching the upper end portion to the anode plate suspension fitting 109a, and the two cathode plates 103b are attached to the cathode plate suspension fitting 109b. The anode plate hanging bracket 109a is electrically connected to the anode side electrode terminal 104a, and the cathode plate hanging bracket 109b is electrically connected to the cathode side electrode terminal 105a. The attachment using the anode plate suspension fitting 109 a and the cathode plate suspension fitting 109 b is the same for the three sets of electrodes including the electrode 103.

  The anode plate 103a of the electrode 103 uses a titanium material as a base material, and an iridium film is formed on the titanium material by a coating method, a plating method, or a welding method. On the other hand, the cathode plate 103b also uses titanium as a base material, and a platinum film is formed on the titanium material by a coating method, a plating method, or a welding method. Since the anode plate 103a and the cathode plate 103b are configured in this manner, an electrode having excellent electric corrosion resistance can be obtained, so that deterioration due to electric corrosion can be suppressed and the electrode can withstand long-term use. It can be.

  Next, the current control device 110 includes three current flow control units 111, 112, and 113 corresponding to the three sets of electrodes, respectively. The positive (+) side terminal of the current control unit 111 is connected to the anode side electrode terminal 104 a provided in the electrolysis apparatus 100, and the negative (−) side terminal of the current control unit 110 is provided in the electrolysis apparatus 100. Connected to the negative electrode terminal 105a. The positive (+) side terminal of the current control unit 112 is connected to the anode side electrode terminal 104 b provided in the electrolysis apparatus 100, and the negative (−) side terminal of the current control unit 112 is provided in the electrolysis apparatus 100. Connected to the negative electrode terminal 105b. Further, the positive (+) side terminal of the current control unit 113 is connected to the anode side electrode terminal 104 c provided in the electrolysis apparatus 100, and the negative (−) side terminal of the current control unit 113 is provided in the electrolysis apparatus 100. Connected to the negative electrode terminal 105c.

  The electrolytic solution 107 stored in the electrolytic bath 101 contains water (pure water) as a main component, but the electrolytic solution 107 in the HHO gas generator 1 has a predetermined amount of sodium carbonate in distilled water at a weight ratio of 0.1. % To 20%, preferably about 5% sodium carbonate aqueous solution is used. Electrolysis can be promoted by the electrolytic solution 107 having such components. As the electrolytic solution, other materials may be dissolved as long as they are inexpensive and safe. Further, when the electrolytic solution 107 can be used in a cold region, it is preferable to mix, for example, ethylene glycol or the like as an antifreezing agent in an appropriate amount according to the temperature at the place of use.

  Moreover, as the power supply device 120, it is preferable to use a 12-volt or 24-volt storage battery mounted on the automobile. Electric power is supplied from the storage battery to the current control units 111, 112, and 113, and the current flowing between the anode plate and the cathode plate in the three electrodes 103 is controlled to a predetermined current value. In this way, by controlling the current value by the current control units 111, 112, and 113, an optimal amount of HHO gas is generated from the HHO gas generation device 1, and heat generation from the three electrodes 103 and the like is suppressed to room temperature. It can be suppressed to the extent.

  In order to generate HHO gas from the HHO gas generator 1 configured as described above, power is first applied from the power supply device 120 to the current control units 111, 112, and 113. By flowing a current of a predetermined current value controlled between the anode plate and the cathode plate in each electrode 103 or the like by the current control units 111, 112, and 113, the electrolytic solution 107 is electrolyzed and foamed HHO. Gas is generated. The HHO gas is accumulated in the upper part of the electrolytic solution 107 in the electrolytic cell 101 and then discharged from the HHO gas discharge nozzle 106 and is supplied to the fine bubble generator 3 through a predetermined pipe.

  FIG. 3 shows an embodiment of the fine bubble generator 3. Here, the ejector-type microfluidic generator 3 will be described as an example. As shown in FIG. 1, the microfluidic generator 3 has a pipe 5 connected to a fuel tank 2 that stores liquid fuel such as light oil, heavy oil, or gasoline to be supplied to an internal combustion engine or a combustion apparatus described later. A liquid fuel flow path 31 for introducing liquid fuel pressurized by the liquid feed pump 6, and a mixed fluid introduction flow path 32 having a mixed fluid introduction hole 32a for introducing HHO gas supplied from the HHO gas generator 1. And a fine fluid generation space 33a for finely dispersing the HHO gas in the liquid fuel and a fine fluid mixing chamber 33.

  The liquid fuel inflow hole 31 a and the fine fluid generation space 33 a communicate with each other by a plurality of (in this case, three) liquid fuel flow paths 31, and the fine fluid generation space 33 a intersects the liquid fuel flow path 31. The liquid fuel guide groove 31c provided in (1) is provided. By providing the liquid fuel guide groove 31c, the liquid fuel discharged from the liquid fuel outflow hole provided on the microfluid generation space 33a side of the liquid fuel guide groove 31c to the microfluid generation space 33a has a mixed fluid introduction hole 32a. The separation area accompanied by cavitation is generated on the discharge surface, so that the introduced HHO gas can be made uniform and fine. As a result, the microfluid mixing chamber 33 has micro- or H-bubbles of HHO gas as liquid fuel. A mixed fuel in which bubbles are dispersed is generated.

  The mixed fluid introduction hole 32 a and the mixed fluid introduction pipe 34 connected to the side surface of the microfluidic generator 3 are communicated with each other through a mixed fluid introduction channel 32 provided in the microfluidic generator 3. When adjusting the introduction amount of the HHO gas, an adjustment valve may be provided in the mixed fluid introduction pipe 34 for adjustment.

  The ejector-type microfluidic generator 3 configured as described above is configured to eject pressurized liquid fuel at a high speed into the microfluidic generation space and mix HHO gas mixed by the turbulent flow action in the separation region accompanied by cavitation generated in the vicinity of the outlet. Can be refined into fine bubbles of 10 μm or less (from microbubbles to nanobubbles).

  The microfluidic generator 3 is not limited to the ejector-type microbubble generating method, and any one of the cavitation method, the swirling method, and the pressure-dissolving method can be selected. As the liquid fuel, any method for generating fine bubbles can be used for a liquid having a low viscosity such as water, but the above-described ejector type method for generating fine bubbles is preferable for a fuel having a high viscosity such as light oil or heavy oil.

  In this way, the mixed fuel in which the microbubbles of HHO gas or the microbubbles of nanobubbles are dispersed in the liquid fuel by the microfluidic generator 3 is introduced into the fuel tank 2 via the pipe 7 and stored. Then, as described above, the liquid fuel mixed with the mixed fuel is pressurized by the liquid feed pump 6, and again the fine fluid generator 3 generates mixed fuel in which the fine bubbles of the HHO gas are dispersed. Is introduced into the fuel tank 2 and stored. That is, a circulation flow path 4 is formed between the fuel tank 2 and the fine bubble generating device 3, and the liquid fuel in the fuel tank 2 is gradually changed to a mixed fuel in which the amount of fine bubbles in the HHO gas reaches a predetermined amount. Change.

  The volume ratio of microbubbles of HHO gas in this mixed fuel is about 1/500 to 1 / 50,000 with respect to the volume of liquid fuel, preferably in a small amount of 1/3000 to 1/7000. good. When the ratio of fine bubbles of HHO gas is large, combustion of HHO gas is dominant in an internal combustion engine to be described later, which is not preferable because it is necessary to readjust the ignition timing. Therefore, in order to make the ratio of the fine bubbles of the HHO gas in the mixed fuel a predetermined volume ratio, the means for adjusting the introduction amount of the HHO gas to the fine fluid generator 3 by the adjusting valve, the operation of the HHO gas generator 1 is operated. Adjust by means of intermittently operating and stopping according to the ratio of fine bubbles of HHO gas, or means of adjusting the ratio of HHO gas by mixing air with HHO gas introduced into the microfluidic generator 3 It is desirable.

  On the other hand, as described above, the mixed fuel generated by the microbubble generator 3 is introduced into the fuel tank 2 and stored, and supplied as fuel for diesel engines such as automobiles and ships as shown in FIG. The FIG. 1 shows a fuel supply system of a commonly used common rail type diesel engine as an example. In FIG. 1, the mixed fuel as the fuel is supplied from the microfluidic generator 3. A supply pump 201, a common rail 202, and an injector 203 are provided in a fuel supply path from the microfluidic generator 3 to the combustion chamber 20 of the engine. Note that a filter is provided between the microfluidic generator 3 and the supply pump 201 as necessary.

  Note that the number of injectors 203 is the same as the number of combustion chambers 20. In FIG. 1, a four-cylinder engine is taken as an example, so that four injectors 203 are provided. For example, in the case of a six-cylinder engine, the number is six.

  In this fuel supply system, after the mixed fuel is received from the microfluidic generator 3 by the supply pump 201 and made high pressure, it is accumulated in the common rail 202 and the high-pressure mixed fuel in the common rail 202 is supplied to each injector. The fuel is injected into the combustion chamber 20 of the engine through 203.

  The mixed fuel that has been sent to the supply pump 201 but not sent to the common rail 202 is sent via a fuel return passage (not shown), and the mixed fuel that has been sent to the common rail 202 but not sent to the injector 203 is Further, surplus fuel not injected into the combustion chamber 20 while being pumped to the injector 203 via the fuel return passage 204 is returned to the fuel tank 2 via the fuel return passage 205.

  The fuel return passage 204 from the common rail 202 and the fuel return passage 205 from the injector 203 are connected to the fuel return passage from the supply pump 201. Among these return fuels, particularly the return fuel from the injector 203 is at a high temperature of, for example, a few hundreds of degrees Celsius. Therefore, when this high-temperature return fuel is returned directly into the fuel tank 2, This leads to an increase in the temperature of the fuel. Therefore, in a normal case, cooling means for cooling the fuel flowing inside the fuel return passage 205 from the injector 203 to the fuel tank 2 is provided.

  In addition, when these return fuels join the fuel return passage 204 and the fuel return passage 205 and return to the fuel tank 2, they join the circulation passage 4 described above. A check valve 8 is provided between the supply pump 201 and the microfluidic generator 3 and the fuel tank 2 so that the return fuel does not flow directly into the common rail 202 by the supply pump 201.

  A generator 206 (or dynamo) is connected to such a diesel engine, and the generator 206 is connected to a storage battery as the power supply device 120 of the current control device 110 described above. When the diesel engine is driven to rotate, the electric power generated from the generator 206 is stored in a storage battery as the power supply device 120 and used as a power source for the current control device 110.

  The common rail type diesel engine shown in FIG. 1 was tested by an automobile equipped with a diesel engine using a mixed fuel in which fine bubbles of HHO gas were dispersed in light oil instead of ordinary light oil. The test vehicle A used a diesel vehicle that uses light oil with a displacement of 2650 cc as fuel. The fuel efficiency when running on a general road for about 200 km using ordinary light oil as fuel was 8.3 km / liter. Next, the fuel consumption when running under the same conditions using the mixed fuel in which fine bubbles of HHO gas were dispersed as the fuel was 12.2 Km / liter. As a result, when the mixed fuel was used as fuel, the fuel efficiency was improved by 45%. Also, when measuring the amount of black smoke required for diesel engine vehicles, it was 15% when using normal diesel oil, but when using mixed fuel, it decreased to 8%, about 50%. It was confirmed to improve. In addition, the exhaust gas was reduced by 47%. As described above, it was confirmed that the fuel efficiency, the black smoke emission amount, and the exhaust gas amount were significantly improved.

  Next, a similar experiment was performed on the test vehicle B. The experimental vehicle B used a diesel vehicle that uses diesel oil with a displacement of 2660 cc as fuel. The traveling condition is the same as that of the experimental vehicle A. As a result, the fuel efficiency when using ordinary light oil as fuel was 6.7 Km / liter, but the fuel efficiency when using mixed fuel in which fine bubbles of HHO gas were dispersed was 11.0 Km / liter. Thus, a fuel efficiency improvement of 64% was confirmed. In addition, when the amount of black smoke was measured in the experimental vehicle B, it was 18% when using ordinary light oil, but it decreased to 7% when using mixed fuel, and further, exhaust gas. As a result, it was reduced by 61%.

  The cause of the difference in fuel consumption, black smoke emission, and exhaust gas amount between the experimental vehicle A and the experimental vehicle B is under investigation, but is thought to be due to the difference in the type of diesel engine depending on the vehicle type. However, in any vehicle type, it is certain that the fuel efficiency is improved by at least 40%.

  On the other hand, in the case of an engine using heavy oil as a fuel, such as a ship, it has been confirmed from an initial experiment result that the fuel efficiency is improved by about 55%. In the case of heavy oil, since the viscosity is high, it is relatively difficult to produce a mixed fuel in which fine bubbles of HHO gas are dispersed. However, the volume ratio of fine bubbles of HHO gas is smaller than the volume of heavy oil. Since a relatively small amount of about 1/500 to 1 / 50,000 is sufficient, fine bubbles of HHO gas at a predetermined ratio can be dispersed in heavy oil even if the viscosity is high. In the case of this heavy oil, since the viscosity is high, the floating speed of the fine bubbles of the dispersed HHO gas is slowed down. In particular, in the case of the nano-bubbled HHO gas, the predetermined volume ratio is maintained even after 24 hours. Therefore, the mixed fuel manufactured by the above-described HHO gas fine bubble mixed fuel manufacturing apparatus can be stored in a tank and injected into a fuel tank such as a ship when necessary.

  FIG. 4 shows a fuel supply system for a common rail type diesel engine as in FIG. 1, but the point different from FIG. 1 is that a mixed fuel as a fuel is supplied from the fuel tank 2. . In FIG. 4, the same reference numerals as those in FIG. 1 denote the same components, and a detailed description thereof will be omitted. The apparatus for producing the HHO gas fine bubble mixed fuel shown in FIG. 4 is the same as that in FIG. 1, and the mixed fuel in which the fine bubbles of the HHO gas are dispersed in the liquid fuel by the fine fluid generator 3 passes through the pipe 7. Then, the liquid fuel mixed with the mixed fuel is pressurized by the liquid feed pump 6, and the HHO gas micro or nano bubble micro bubbles are dispersed again by the micro fluid generator 3. After the mixed fuel is generated, a circulation flow path 4 is formed to be introduced into the fuel tank 2 and stored via the pipe 7, and the liquid fuel in the fuel tank 2 is gradually changed to the mixed fuel.

  In the fuel supply system of the common rail diesel engine shown in FIG. 4, the mixed fuel stored in the fuel tank 2 is supplied to the combustion chamber 20 via the fuel supply path. Even in this example, since the mixed fuel in which fine bubbles of a predetermined amount of HHO gas are dispersed in light oil is used, fuel consumption, black smoke emission amount, and exhaust gas amount can be remarkably improved.

  The apparatus for producing the HHO gas fine bubble mixed fuel shown in each of the above-described embodiments may be expected to fail depending on circumstances. It becomes a cause of a loss that a car or a ship becomes inoperable due to the failure of this apparatus. For this reason, in the manufacturing apparatus of the HHO gas fine bubble mixed fuel by this invention, even if it is a failure, it has considered so that it can return to a normal driving | running state.

  In the HHO gas fine bubble mixed fuel manufacturing apparatus shown in FIG. 1, if the HHO gas generator 1 fails, the HHO gas is not supplied to the fine fluid generator 3. At this time, since the ejector-type microfluidic generator 3 is provided with the liquid fuel guiding groove 31c, the liquid fuel can circulate even if the HHO gas is not supplied from the HHO gas generator 1. Therefore, since the liquid fuel similar to that in the normal case is supplied to the combustion chamber of the internal combustion engine, the normal operation state can be restored. In the HHO gas fine bubble mixed fuel production apparatus shown in FIG. 4, since the mixed fuel as the fuel is supplied from the fuel tank 2, for example, the HHO gas generator 1 and the fine fluid generation in the circulation channel 4 Even when at least one of the device 3 or the liquid feed pump 6 fails, the fuel is supplied from the fuel tank 2, so that the normal operation state can be restored without any trouble.

  On the other hand, when the internal combustion engine (engine) of an automobile or ship is started, the HHO gas generator 1 and the microfluidic generator 3 are also started at the same time, so there are no fine bubbles of HHO gas in the liquid fuel in the fuel tank 2. Or the remaining amount of fine bubbles is low. Even in this case, since the mixed fuel is quickly supplied from the fine bubble generating device 3, it is possible to obtain an improvement in fuel consumption from the start.

  FIG. 5 shows an embodiment in which an apparatus for producing HHO gas fine bubble mixed fuel is applied to a combustion apparatus. 5, the same reference numerals as those in FIG. 1 denote the same components, and a detailed description thereof will be omitted. The apparatus for producing the HHO gas fine bubble mixed fuel shown in FIG. 5 is the same as that shown in FIG. 1, and the mixed fuel in which the fine bubbles of HHO gas are dispersed in the liquid fuel by the fine fluid generator 3 passes through the pipe 7. Then, the liquid fuel mixed with the mixed fuel is pressurized by the liquid feed pump 6, and the HHO gas micro or nano bubble micro bubbles are dispersed again by the micro fluid generator 3. After the mixed fuel is generated, a circulation flow path 4 is formed to be introduced into the fuel tank 2 and stored via the pipe 7, and the liquid fuel in the fuel tank 2 is gradually changed to the mixed fuel.

  The combustion apparatus shown in FIG. 5 shows a burner 30 as an example, and many are generally used with A heavy oil as fuel. As the fuel to be supplied to the burner 30, the mixed fuel stored in the fuel tank 2 is supplied to the burner 30. Even in the case of this example, for example, since a mixed fuel in which fine bubbles of a predetermined amount of HHO gas are dispersed in heavy oil A is used, fuel consumption, black smoke emission amount, and exhaust gas amount can be remarkably improved. .

  Although the present invention has been specifically described above based on the embodiments, it is needless to say that the present invention is not limited to the above embodiments and can be variously modified without departing from the gist thereof. In each of the embodiments described above, light oil and heavy oil are exemplified as liquid fuels for internal combustion engines and combustion devices, but in addition, various waste oils such as gasoline, bioethanol, biogasoline, lubricating oil and edible oil, etc. A mixed fuel in which fine bubbles of HHO gas are dispersed can be obtained. Moreover, as an internal combustion engine and a combustion device, in addition to automobile and ship engines, various agricultural machines such as generators with engines, tractors, tillers, rice transplanters, rice harvesters, brush cutters, aircraft engines, or It can also be applied to engines for construction and construction machinery.
