Description

Sprayer and mixer of oxygen, hydrogen and liquid fuel for internal-combustion engine

The present invention relates to an injection mixer for injecting and mixing oxygen, hydrogen, and liquid fuel for an internal combustion engine. The present invention relates to a liquid fuel which is a hydrocarbon-based compound such as gasoline used in an internal combustion engine that is used as a driving force for automobiles, and the like. The present invention relates to an injection mixer for injecting oxygen and hydrogen to mix well at an appropriate ratio to be introduced into an internal combustion engine so as to cause efficient combustion.

In general, an internal combustion engine spray mixer sprays only liquid fuel into an internal combustion engine, vaporizes liquid fuel into an internal combustion engine, or mixes liquid fuel and air into an internal combustion engine to perform combustion.

In the case of a vehicle using such a conventional spray mixer, incomplete combustion is the biggest defect and causes environmental pollution. In other words, the exhaust gas generated when the vehicle is traveling at a low speed has a great impact on the urban environment. Furthermore, when the vehicle is driven at a speed higher or lower than the normal speed, or when driving in a delayed or congested area, incomplete combustion As a result, the exhaust gas is a serious pollutant to the environment.

In addition, when the liquid fuel and air are mixed and injected into the internal combustion engine, nitrogen, argon, carbon dioxide, and dust, which are unnecessary for combustion, are mixed into the mixed air, resulting in low combustion efficiency and incomplete combustion, resulting in air pollution. There has been a problem that causes the double.

To improve these problems, to improve combustion efficiency and complete combustion, such as using more refined fuel, supplying compressed gas or liquefied air when fuel is supplied, or purifying the entrained air to be sucked in. Therefore, many studies have been made to reduce the emission of pollutants or to purify the exhaust gas, but its efficacy has not been greatly increased, and thus it is not effective.

On the other hand, the applicant (Baek Ok-rim) developed a gas generator that generates gaseous fuel by electrolyzing water in order to use oxygen and hydrogen required for combustion as gaseous fuel, and applied for a utility model registration application (Korean Utility Model Registration No. 0247546). However, in the case of providing two fuels, which are oxygen and hydrogen generated from the gas generator, and a liquid fuel, which is a hydrocarbon compound supplied separately from each other, the hydrogen is highly reactive, so it is not safely burned but exploded, causing safety problems. Since the necessity of the development of a mixer capable of efficiently mixing the oxygen and hydrogen and liquid fuel is present to the present application.

In order to solve the above problems, the present invention can stably electrolyze water to use clean oxygen and hydrogen generated therefrom as gaseous fuel, and liquid fuel supplied separately from such gaseous fuel is mixed smoothly with gaseous fuel. The technical problem is to provide an injection mixer that can prevent the explosion to occur and can be burned efficiently.

The present invention, in order to realize the above technical problem, a gas fuel supply pipe supplied with oxygen and hydrogen supplied from a gas generator, a liquid fuel supply pipe supplied with a liquid fuel, a mixing pipe in which the fuels supplied are mixed, mixed fuel It can be made by providing a spray mixer consisting of a mixed fuel filtration network for filtering the mixed fuel with a large particle does not pass and a mixed fuel supply pipe for supplying the mixed fuel to the combustion chamber.

The injection mixer may be configured to add a known regulator capable of sensing the amount of fuel supplied as a sound wave generated therein and a control valve known to control the amount of fuel supplied during fuel supply. The control valve may be driven by an electrical signal, but the gas fuel supply pipe and the liquid fuel supply valve may be installed at the ends of the gas fuel supply pipe and the liquid fuel supply pipe to automatically adjust the amount of fuel supplied. In addition, by blocking and enclosing these valves, the interior of the spray mixer of the present invention may be divided to form a vacant space and a mixing chamber to further form a barrier wall to prevent mixed fuel from filling in unnecessary space. This allows for more efficient fuel mixing.

Hereinafter, with reference to the accompanying drawings, a configuration for an embodiment of the present invention will be described in detail.

The injection mixer 1 of the present invention is composed of a gas fuel supply pipe 11 and a liquid fuel supply pipe 13 from the outside of the left side to the inside right side, and the supply pipes 11 and 13 at the ends of the supply pipes 11 and 13. 13) to provide a gas and liquid fuel mixing tube (15) to allow the fuel supplied from the mixture to be mixed with the discharge hole (152a, 152b) in the upper and lower portions at the bottom with respect to the center point of the injection mixer (1) In the upper part of the mixing tube 15, a mixed fuel filtration network 17 is provided from the center point of the injection mixer to the center of the inside at a predetermined distance from the mixing tube 15, and the mixed fuel having large particles in the mixed fuel Large particles may be filtered so that the mixed fuel may not be passed, and the mixed fuel passing through the mixed fuel filtration network 17 may be supplied to the combustion chamber (engine) 3 through the mixed fuel supply pipe 19.

In order to mix the fuel more smoothly, it is preferable that the end of the gas fuel supply pipe 11 is located at the rear left side than the end of the liquid fuel supply pipe 13. This is because the injection speed of the gas fuel is faster than the injection speed of the liquid fuel, and when the gas fuel is injected from the rear, the fuel is mixed well.

At this time, oxygen and hydrogen, which are gaseous fuels, will naturally have a mixing ratio of 2: 1 (hydrogen: oxygen) during electrolysis, and the mixing ratio of gaseous fuel and liquid fuel consisting of oxygen and hydrogen will be 65 to 75%, liquid fuel. It is preferable to make 25 to 35%. Because the increase in the amount of gaseous fuel containing hydrogen increases the explosive power, the existing internal combustion engine does not endure the explosive force, damage to the engine itself or damage to the drive device due to excessive driving force occurs. This is because it is only possible to operate the engine without maintaining a proper mixing ratio. This mixing ratio is the conclusion that the applicant of the present application, after many years of experiment, such a mixing ratio can smoothly operate the internal combustion engine without changing the structure of the existing internal combustion engine.

On the other hand, when hydrogen and a hydrocarbon compound are mixed, a natural hydrocarbon is generated when the hydrocarbon compound, which is a liquid, is atomized, that is, in a gaseous phase and is not mixed but is mixed in a liquid phase. However, the prevention of spontaneous explosion prevents spontaneous explosion by injecting liquid liquid fuel through the liquid supply pipe 13 so that the liquid fuel is changed into a gaseous fuel having fine particles. You can do it.

The spray mixer (1) has a known regulator (12), a known gas fuel control valve (112) and a liquid fuel control, which can sense the amount of gas fuel and liquid fuel supplied as sound waves generated therein. When a lot of output is required by laying the valve 132, the senser 12 may detect this and open the control valves 112 and 132 so that a large amount of fuel may be supplied. The sensitizer 12 and the control valves 112 and 132 are electrically connected to each other to give an electric signal from the sensitizer so that the control valves 112 and 132 move up and down to adjust the amount of fuel supplied.

In addition, the chambers 14 and the mixing chamber 18 are divided by dividing the interior of the spray mixer 1 while supporting and sealing some of the valves 112 and 132 and the supply pipes 11 and 13. By forming a barrier wall (16) to be formed so that the mixed fuel is not filled in the unnecessary space, the fuel can be mixed more efficiently.

Hereinafter, the configuration of the present invention described above in more detail. The gas fuel supply pipe 11 and the liquid fuel supply pipe 13 are inserted into the injection mixer 1 in a straight line from the outside when viewed from the side, and inside the gas and liquid fuel mixing pipe 15 is bent upwardly Consists of a triangular shape gathered to the center of the gas and liquid fuel mixing tube (15) when viewed in a plan, so that the end of the gas fuel supply pipe (11) is located to the left rear than the end of the liquid fuel supply pipe (13) consist of.

Although the volume of the engine may vary according to the displacement of the vehicle to be applied and the amount of fuel required for combustion may vary, the gas fuel supply pipe 11 has a diameter of 4 to 5 mm outside the injection mixer 1, The diameter of the tip inserted into the mixing pipe 15 is 0.2 to 1.8 mm; The liquid fuel supply pipe 13 has a diameter of 5 to 7 mm outside the injection mixer 1 and a diameter of the end inserted into the mixing pipe 15 to 0.2 to 1.8 mm to atomize the liquid fuel. It can be made in a gaseous phase, and the optimum value for the best mixing of gaseous fuel and liquid fuel.

In the above, the pressure for injecting the gas fuel from the gas fuel supply pipe 11 is 2 to 4 pascals, and the pressure for injecting the liquid fuel from the liquid fuel supply pipe 13 is 4 to 7 pascals. It is desirable to.

The mixed fuel filtration network 17 is composed of a dense mesh type having a mesh of 200 to 300 µm in order to filter out the mixed fuel having large particles in the mixed fuel.

The mixing pipe 15 is provided with discharge holes (152a, 152b) in the upper and lower so that the mixed fuel can be discharged up and down. The discharge holes 152a and 152b are inclined at an angle a of 30 to 40 ° when viewed from the cross-section of FIG. 1B and based on a horizontal line, and the diameter of the discharge holes 152a and 152a is formed to be 0.7 to 0.8 mm. The mixed fuel exited to) is spread out to the upper portion of the mixing chamber 18 so that more mixing can be achieved, and the mixed fuel exiting into the lower discharge hole 152b impinges on the inner surface of the mixing chamber 18. It is configured to spread to the mixing chamber 18, and as shown in FIG. 1c, the upper discharge hole 152a is located close to the blocking wall 16 as viewed in the longitudinal direction so that the inlet is inclined backward. The lower discharge hole 152b is formed so as to be in close proximity to the mixed fuel supply pipe 19 so as to be inclined forward.

Hereinafter will be described the operation of an embodiment in which the injection mixer of the present invention configured as described above is applied to the gas generator and the engine of an automobile.

First, the overall schematic configuration is shown in FIG. 3. The generation of oxygen and hydrogen, which are gaseous fuels, includes a gas separator 21, a water storage tank 23, and a gas supply pipe 25. 201) is generated by the gas generator (2) consisting of an operating unit 200 consisting of a gas output tank 203 and a backflow preventer 205, which is sprayed and mixed with oxygen and hydrogen and a liquid fuel which is a hydrocarbon compound The injection mixer 1 and the engine 3 which generate | occur | produce a driving force by burning these fuels are comprised.

First, oxygen and hydrogen are separated from the water and the water stored in the reservoir tank 23 of the gas generator 2 through the gas separator 21, and oxygen and hydrogen are separated into 1: 2, and the gas fuel is separated into the gas supply pipe 25. Through the gas storage tank 201 through the gas output tank 203 is moved to the injection mixer (1).

The gas fuel thus moved is introduced through the gas fuel supply pipe 11, and the gasoline, which is the liquid fuel, is injected through the liquid fuel supply pipe 13 through the liquid fuel control valve 31 used in a general engine. Will move inside.

The fuel moved as described above is mixed with each other in the gas and liquid fuel mixing pipe 15, the liquid fuel is injected into the gas and liquid fuel mixing pipe 15 through the liquid fuel supply pipe 13 to turn into fine particles The fuel is injected, and the gas fuel containing oxygen and hydrogen is 1: 2 is injected from the rear of the liquid fuel supply pipe 13, so the gas fuel having a high injection speed is injected from the rear of the liquid fuel, so the two fuels are mixed well. The liquid fuel is discharged from the liquid fuel supply pipe 13, so that it is injected into a fine gas phase (phase phase) state, so that natural explosion does not occur even when mixed with hydrogen.

At this time, the gas fuel and the liquid fuel can be mixed in the best mixing ratio of the combustion efficiency, that is, 65 to 75% of the gas fuel, 25 to 35% of the liquid fuel by the operation of the control valve (112, 132).

The mixed fuel mixed is discharged to the mixed fuel chamber 18 through the discharge holes 152a and 152b, and only the fine gaseous mixed fuel passing through the mixed fuel filtration network 17 is mixed fuel supply pipe (19). ) Is supplied to the engine (3).

Next, the vehicle is driven by the maneuvering power of the combustion explosion of the general engine 3.

As seen above, the liquid fuel is injected into the fine gaseous phase while passing through the liquid fuel supply pipe 13, and the gaseous fuel (oxygen + hydrogen) is injected from the rear, so that hydrogen and liquid fuel having high explosive force are injected. Since the mixture is uniformly mixed and the oxygen to assist their combustion is also uniformly mixed, a small amount of liquid fuel (gasoline) can generate enough maneuverability, and it is sufficient even without using a large amount of liquid fuel (gasoline), a hydrocarbon compound. The explosive power can be used to save energy, and the use of pure oxygen and hydrogen reduces the amount of substances that can pollute the atmosphere. In addition, since liquid fuel is mixed with hydrogen in the gas phase rather than in the liquid phase, natural explosion of hydrogen does not occur.

In the above, the detector 12, the gas fuel control valve 112 and the liquid fuel control valve 132 detects the sound wave generated from the gas and liquid flowing through the respective supply pipes (11, 13) to detect the amount of fuel supply When the driver climbs the hill or the driver steps on the accelerator for rapid acceleration, each of the control valves 112 and 132 is opened to increase the inflow rate of oxygen-based hydrogen and gaseous hydrocarbon-based compounds such as gasoline. The output of the engine 3 is increased. In this case, when more than the required fuel is supplied, the amount of gas and fluid flowing through the gas fuel supply pipe 11 and the liquid fuel supply pipe 13 increases, and the sound absorber 12 detects more than an appropriate amount of sound waves in the reactor 12 so that the air conditioner 12 In order to reduce the amount of fuel introduced by sending a signal to lock the control valves 112 and 132, and when the amount of fuel supplied is small, the amount of fuel supplied is reversed to increase the amount of fuel supplied. More precise control.

Since the above embodiments do not limit the scope of the present invention, the modified embodiments without departing from the technical spirit of the present invention from the viewpoint of those skilled in the art will not depart from the scope of the present invention.

As described above, when the injection mixer according to the present invention is used as a fuel injection mixer of an internal combustion engine together with a gas generator, only oxygen and hydrogen without unnecessary nitrogen, argon, carbon dioxide, dust, etc., are used as the gas fuel. As a result of the complete combustion, the content of pollutants causing air pollution in the exhaust gas discharged after combustion is remarkably reduced. Since hydrogen is used as gas fuel, the amount of hydrocarbon compounds such as gasoline is significantly increased. Reduced use of expensive liquid fuel is reduced, and the amount of fuel supplied by the regulator, gas fuel control valve and liquid fuel control valve can be sensed and the amount of fuel can be controlled immediately. In a gas phase where the fuel is not a liquid phase Since the cow and mix it in a safe number to use hydrogen as a fuel and not the nature of hydrogen explosion occurred.
