PURPOSE:To increase the efficiency of fuel consumption of an internal combustion engine, by ejecting fuel from a nozzle disposed in a vaporizing container, baporizing fuel in the container, and drawing the vaporized fuel into an intake pipe at a required rate. CONSTITUTION:In feeding vaporized fuel into a fuel supply pipe 1, liquid fuel in a fuel tank 10 is at first drawn up by a pump 13. Then, the liquid fuel is sprayed, under a high pressure, upward from an injection nozzle 12 disposed near the bottom of a conical vaporizing container 8, the diameter of which is decreased toward its top, at a rate greater than the quantity into the fuel supply pipe 1 by the negative pressure. Here, the particle sizes of fuel are reduced toward the top of the container 8 and vaporization of fuel is promoted, whereas the particle sizes of fuel near the inner wall surface of the container are relatively large, so that the fuel near the inner wall surface of the container is recovered into the fuel tank 10 via revovery pipe 9. Only the vaporized fuel in the container 8 is drawn into the pipe 1 and supplied to an engine 3 through a venturi 5.

Description

DETAILED DESCRIPTION OF THE INVENTION The great invention is a vaporization device for an internal combustion engine, more specifically a vaporization device (carburator) that can mix gas (air) and liquid (gasoline) in an optimal state, especially for a gasoline engine. The purpose of the vaporization device is to provide a vaporization chamber for vaporizing the caustic material in front of the air inflow pipe that sends the air-fuel mixture to the engine side, and to draw only the vaporized fuel from the vaporization chamber into the inflow pipe. An object of the present invention is to provide a completely new and revolutionary vaporization device for an internal combustion engine that is optimal for energy saving and can significantly improve fuel consumption efficiency.

Another object of the present invention is to provide a vaporizing device which can be expected to have a completely unexpected effect by allowing the use of diesel oil as a fuel for a gasoline engine.

In general, in the structure of fuel vaporizers for internal combustion engines, particularly gasoline engines, a spray vaporization method based on the negative pressure of a venturi tube is most commonly used, and its popularity is worldwide.

However, the particle size of the vaporized particles is approximately 200 ~ 3
00. Because it is a coarse particle of about # size, in terms of furnace firing efficiency, due to the recent rise in lighting costs, the intermittent heat is attracting attention. In other words, in terms of combustion efficiency, the finer the particle size of the vaporized burnt material, the more uniform the distribution to each cylinder and the higher the consumption rate of the furnace material.Therefore, various industries are already working on the development of fine particle vaporization methods. is being carried out. However, in conventional vaporizers, Pentu IJ
The technical idea is to atomize gasoline by reducing i and increasing the air flow rate through the venturi, so when the air flow rate exceeds a certain speed, negative pressure due to resistance increases, reducing suction efficiency and reducing output. There were many problems with the decline in

Therefore, the conventional means of obtaining atomization by reducing the amount of paint particles does not cause a decrease in output, and it has not been possible to achieve atomization to the extent that the consumption efficiency can be improved.

In any case, in the conventional technology, we have succeeded in developing the technology to satisfy the fuel consumption efficiency as particulate vaporization technology.

As a result of technological development focusing on these points, the present invention has made it possible to significantly improve fuel consumption efficiency by turning the fuel into fine particles and turning it into vaporized fuel before introducing it into the air inflow pipe. The company has developed a ground-breaking vaporization device that is characterized by the fact that a vaporization container is installed between the air inflow pipe that sends the air-fuel mixture from the air cleaner side to the cylinder side, and that the fuel is placed inside the B vaporization container. The configuration is such that an upward spray nozzle for high-pressure injection is provided, and a spray amount exceeding the suction amount is diffused and ejected from the spray nozzle, so that only the vaporized fuel corresponding to the suction amount is induced into the air inlet pipe side. The specific structure thereof will be explained below according to the embodiments shown in the drawings.

・, 1. The diagram is a schematic system diagram of a gasoline engine including an uninvented carburetor, and +ll in the diagram is an air cleaner (2).
and each cylinder (4a) of the 4-cycle engine (3)
, (4b), (4c), and (4d) with a sliding air inflow pipe that connects the venturi pipe section (5) and the choke valve (
6) and a throttle valve (7).

(8) is a conical vaporizer with a tapered upper part, and the tip part (81
is connected to the venturi pipe portion (5) of the air inflow pipe 111. (9) is an excess spray liquid collection pipe vertically installed from the bottom of the conical vaporization container (81) into the fuel tank (1O);
11) is a static pressure introduction pipe connected from the air inflow pipe (1) to the bottom side of the vaporization container (8), and (121) sprays fuel at high pressure via a pump 031 directly connected to the fuel tank (10). A spray nozzle is provided near the bottom of the vaporization container (8). +141 indicates a safety valve provided directly below the air cleaner 12) to prevent the vaporized fuel from returning.

Since the present invention is configured as described above, the pump +1
31, the fuel is injected upward at high pressure into the vaporization container (8) from the spray nozzle 021, and the injected atomized body is injected in an excess amount exceeding the suction amount, and the injected particle structure is formed at the tip. The closer to the periphery of the vaporizer, the finer particles become smaller than l OO,IL and the generation of vaporized gas is promoted, while coarse particles are simultaneously generated on the outer periphery b0 Therefore, in the present invention, once the vaporization container (8 ) in the spray nozzle (12
), the fuel is ejected and turned into a vaporized gas state. At that time, since the vaporization container (8) becomes conical,
Since the particles ejected from the nozzle Q21 are diffused and ejected and guided to the tip side, a vaporized gas state in which the fuel is concentrated can be easily obtained at the tip.

In this way, in the present invention, the nozzle (12) is provided in the vaporization container (8) to perform pressure diffusion injection of fine particles that are not obtained by pressure injection due to the suction negative pressure that may normally occur when the engine is running. By doing so, we were able to easily obtain fine particles close to gasification together with coarse particles.

In this way, an excess of vaporized fuel exceeding the consumption amount is generated in the vaporization container (8).
8) Since the tip part (81) is connected to the venturi pipe part (5) of the air inflow pipe (1), only the required amount of vaporized fuel is transferred to the air inflow pipe ( At the same time, it is naturally attracted and introduced to the 11 side, and at the same time mixes with air to form an air-fuel mixture.As the throttle valve (7) opens Kff5, the cylinders (4a), (4b), (4c),
It is sucked into (4d). On the other hand, the coarse particle fuel that is not induced to be introduced has a high particle specific gravity within the container, naturally falls to the bottom due to its own weight, and returns to the tank (10) through the collection pipe (9).

Furthermore, the air-fuel mixture sucked into this cylinder contains only fine particles that have been vaporized to the gasified state of the fuel, so the cylinder is completely gasified, and the distribution to each cylinder is also affected. This can be done uniformly, thereby greatly improving the fuel consumption rate, and since the particles are fine, it is possible to prevent cylinder wear and damage. Furthermore, the surface area of the air-fuel mixture into the cylinder is increased, which has the effect of increasing the combustion rate.

As described above, the great invention is to provide a nozzle in the vaporization container, and to inject fuel from the nozzle at high pressure in excess of the required amount, to completely vaporize the fuel in the container, and then to supply the required amount to the air inlet pipe. The purpose of this system is to send only the vaporized fuel corresponding to the amount of fuel and mix it with air, so even if coarse particles are generated simultaneously in the container, the coarse particles will not be sent into the air inlet pipe.

Therefore, not only is the fuel consumption efficiency much higher than that of conventional carburetors, but it also has the advantage of preventing cylinder wear and damage caused by coarse particles. Therefore, by incorporating a nozzle into the air inlet pipe and directly injecting the air, it is possible to prevent coarse particles from being sent into the cylinder.

In addition, in the relationship between the suction amount on the engine side and the fuel injection amount, negative pressure may be generated in the container due to the induced negative pressure, and the attraction ability may be significantly reduced. A static pressure introduction pipe (11
) is installed to introduce static pressure into the gator (8) to adjust the negative pressure so that only the vaporized fuel is sent quickly in response to the amount of suction. The harmful effects of pressure are eliminated and it becomes sticky.

In addition, the opening/closing degree of the throttle valve (7) is set to #a adjustment depending on whether the engine rotates at low speed or high speed.

Furthermore, in the invention, since fuel is injected in excess of the suction consumption on the engine side, when the particle density of the fuel, especially the coarse particle fuel, increases in the fixed amount container (8), contact and adhesion effects occur with each other. The specific gravity of the particles increases and they fall naturally under their own weight, and the excess spray liquid collection pipe (9) at the bottom of the container (8)
) into the fuel tank flOi.

In this embodiment, since the vaporization container (8) is formed into a conical shape, the atomized material injected from the nozzle is diffused and injected onto the inner wall of the container, and at the same time collides with the container to become fine particles and is easily promoted to the vaporization state. Although this is a favorable condition in which the fuel is concentrated on the tip side, the shape of the container is not necessarily limited to a conical shape, as long as the atomized material injected from the nozzle can be diffused. Therefore, for example, when a plurality of nozzles are used, a cylindrical shape may be used. In addition, the shapes of the air inflow pipe, static pressure introduction pipe, etc. are by no means limited to the embodiments. In addition, in the above embodiment, a safety valve 041 is provided directly below the air cleaner (2), so that a safety measure is taken by preventing vaporized fuel from returning to the air cleaner (2) side when the engine is stopped, etc. When installing α4), the position is not necessarily determined.

As described above, a vaporizing container is provided, and an upward spray nozzle is provided in the container to inject the fuel by polymer diffusion, and the amount of spray is consumed by the engine. By injecting in excess of the amount, the fuel is vaporized in the vaporization container until it becomes gasified by fine particles, and only the vaporized fuel according to the amount required by the engine is sent to the cylinder via the air inlet pipe. Therefore, the percentage of fuel sent into the cylinder is
It has a fine particle structure that is completely vaporized and gasified, making it possible to completely uniformly distribute it into each cylinder, making it extremely practical and extremely efficient in terms of fuel consumption compared to conventional carburetors. This has resulted in a completely revolutionary effect as an energy-saving measure.

In addition, coarse particles are also generated in the vaporization container at the same time as fine particles, but since the coarse particles are returned to the fuel tank outside the container, they do not get mixed into the cylinder. There are secondary effects.

Furthermore, by using a vaporization device related to the unexploded F3AK, it is possible to drive a gasoline engine even with diesel fuel, which has traditionally been used in gasoline engines because it has a worse vaporization rate than gasoline, which is a completely revolutionary effect. I ended up getting this. As a result, the use of fuel-efficient and inexpensive light oil has led to the solution of energy saving and water removal. In addition, it is lighter and more compact than a diesel engine, and has a large horsepower due to multiple rotational speeds.

In addition, the vaporizer according to the present invention can be widely used as an internal combustion engine for automobiles, ships, etc., and has many other useful effects.
