Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used for internal combustion engines of passenger cars, trucks, buses, agricultural machines, ships, boilers, etc., and the fuels of these internal combustion engines are gasoline, light oil, heavy oil, Improving the quality of liquid fossil fuels such as kerosene quickly and strongly to reduce fuel consumption of internal combustion engine, increase horsepower and torque, and reduce CO, HC in exhaust gas,
The present invention relates to a fuel reforming device capable of obtaining a large reduction in particulate matter and black smoke.

[0002]

2. Description of the Related Art Conventionally, fuel reforming methods for internal combustion engines are magnetic, metal, ceramic, ore powder such as tourmaline and barite,
Alternatively, various methods such as a combination of a plurality of these methods have been tried. Most of these methods are used by directly mounting in the fuel tank.

Japanese Utility Model Registration No. 3036323 discloses a technique in which a mixed spherical body of ceramic powder and ore powder is placed in a cylindrical container and immersed in a fuel liquid in a fuel tank. This technique is a method in which a hard metal plate that is made into a cylindrical shape by making a hole is used as a container, and the container is mounted in a fuel tank.

The technique using the barley stone powder disclosed in Japanese Patent Laid-Open No. 7-197048 is also a method of directly charging the fuel tank.

[0005]

The conventional fuel reforming device has two problems. The first point is that today's passenger cars and the like have a structure in which nothing can be put in the fuel tank, and it is difficult to attach a fuel reformer of the type that is immersed in the fuel tank. This is because the fuel system of a passenger car often has a thin and distorted refueling pipe, or has a check valve or a foreign material mixture prevention net in the middle of the refueling pipe, and it cannot be installed in the tank unless the fuel tank is modified. It is impossible. The second point is the utility model registration number No. 303 described in paragraph 0003.
A hard metal container is used, such as the cylindrical container used in the 6323 technique. Hard metal containers
There is a risk of damaging the fuel tank or generating sparks due to vibrations and shocks while the vehicle is running, which is a safety issue.

Further, the conventional techniques generally have a high manufacturing cost and a low degree of improvement in fuel consumption. As a result of various tests conducted by the inventor in the process of developing the present invention, the fuel consumption improvement rate is 1
When it is 5% or less, it is almost difficult for the driver to realize the improvement of fuel consumption in daily running under different running conditions every day. In order for the driver to feel the improvement in fuel consumption, an improvement rate of 20% or more is required. Fuel reforming equipment that does not allow drivers to feel the improvement in fuel consumption does not spread to society. Therefore, in order to popularize fuel reforming equipment, save petroleum fuel and reduce harmful exhaust gas, and contribute to the improvement of the social environment, daily driving in urban areas is required.
%, It is necessary to develop a fuel reforming technology that can achieve an improvement rate of 30% or more in highway driving, and it is necessary to realize this at a low price.

There are four problems to be solved by the present invention with respect to the above problems. First of all, it must be a fuel reformer that can be easily installed in passenger cars, trucks, buses, and other power machines having an internal combustion engine without modifying the structure of each oil supply system. Secondly, it is a highly safe fuel reformer that does not damage the inside of the fuel tank due to vibrations or shocks while the vehicle is running, and does not generate sparks due to collision with the refueling system structure.
Third, a fuel reformer that achieves a high fuel efficiency improvement rate of 20% or more in daily city driving and 30% or more in highway driving. Fourth, it can be manufactured at a low price and can be widely spread in society. In developing the present invention, the above four points were addressed as problems to be solved.

[0008]

[Means for Solving the Problems] First of the problems to be solved,
The following two measures have been taken against the fact that the equipment can be easily installed in any type of power engine without modifying the refueling system structure. The first measure is not only for devices that can be put in the fuel tank (Figs. 3 and 4, for trucks, buses, and other power engines), but also for check valves in the fuel pipes of passenger cars, etc. We devised a fuel reforming device (Figs. 1 and 2, for passenger cars) that is a device that is attached to the front, that is, near the fuel filler port, and that uses a flexible cylinder made of stainless mesh as the container of the fuel reforming member. did.

The shape and method of use of the above-mentioned device (for passenger cars) of the type that is attached near the fuel filler port are as follows.
A fine mesh made of stainless steel is wrapped in multiple layers to form a cylinder, which is welded strictly to form a container for the fuel reforming member. A stainless steel chain is attached to this container, and a highly elastic stainless wire having a diameter of 4 to 20 cm (the required diameter size varies depending on the thickness of the filler neck and the pipe) is attached to the tip of the chain. The equipment can be attached to the passenger car by inserting the container (equipment body) into the refueling pipe from the refueling port, pushing the wiring into an elliptical shape, and then releasing it in the pipe in the immediate vicinity of the refueling port. Due to its elastic repulsion, the wiring remains close to the filler opening. According to the present invention, the fuel reforming device can be attached without breaking the check valve of the passenger car or the like or the foreign matter mixture prevention net. Since this stainless steel mesh container is flexible, it can be attached even when the oil supply pipe is distorted.

The shape and method of using an instrument (for trucks, buses, other power engines) that can be put in a fuel tank are as follows. A fine mesh made of stainless steel is wrapped in multiple layers to form a cylinder, which is welded strictly to form a container for the fuel reforming member. The size of the container depends on the vehicle used. A thin stainless wire is attached to this container, and a snap is attached to the tip of the wire. To attach the device to a vehicle, etc., put the container (the device body) into the fuel tank from the fuel filler port, and put the snap near the fuel filler port (the hole of the circular metal plate provided directly below the fuel filler port or the back side of the fuel filler cap). To stop it.

As a second measure against the first problem to be solved described in paragraph No. 0008, even if the fuel in the fuel tank is not constantly immersed, that is, when the fuel is refueled from the refueling port, it is momentarily in the refueling pipe. We have developed a fuel reforming member that can sufficiently reform the fuel just by immersing it in water.

The fuel reforming member is obtained by heat-treating the Tanamine granite and the rare earth ore produced in Jilin Province of the People's Republic of China in a ratio of 4 to 1 according to the present invention. It was possible to have a powerful and instantaneous acting force.

With respect to the second problem to be solved by the present invention, that is, a safe device which does not damage the fuel tank and does not generate sparks against vibration or shock, paragraph 000
The problem can be solved by using the stainless mesh cylinders described in 9 and 0011 as the container of the fuel reforming member. Since the stainless steel container is flexible, it does not collide with impact and generate no sparks. This has achieved shock absorption, safety, oil resistance, and rust prevention.

Regarding the third problem, a fuel reformer capable of realizing a high fuel efficiency improvement rate of 20% or more in daily city driving and 30% or more in highway driving, as a result of various trial and error, Tamine Granite Rock We devised a granular fuel reforming member by heat treating and mixing radioactive rare earth ore from Jilin Province. As will be described in detail in the subsequent manufacturing examples, this modifying member allows 20 to 35% in daily city driving and 3% in highway driving.
Achieved a fuel efficiency improvement of 0-45%, and a 12-15% improvement in horsepower and torque at a practical engine speed of 2500-3000 rpm. Furthermore, in a diesel vehicle, black smoke and offensive odor of exhaust gas are achieved. It has succeeded in reducing harmful exhaust gas to a state where it almost disappears.

The fourth problem, that it can be manufactured at a low price and can be widely spread in society, can be realized. The materials used for the fuel reforming device of the present invention, Tamine Granite, radioactive rare earth ore from Jilin Province, SUS304 stainless mesh, chain and wire, etc., are readily available, and jigs and welding methods are also available. Does not require a highly difficult technique, and the fuel reforming device of the present invention can be manufactured at low cost.

[0016]

In the present invention, Tamine Granite, which is the center of the fuel reforming member, strongly emits far-infrared rays as shown in FIGS. 5 and 6, and emits a very small current and a slight vibration in the liquid. When this is mixed with radioactive rare earth ore from Jilin Province, these acting power and instantaneous working property are further enhanced. Moreover, this action has a very long duration and is completely restored by heat treatment. The reforming of petroleum fuel and the improvement of combustion efficiency are achieved by the fact that the molecular bond (cluster) of the liquid fuel is subdivided by the above action to increase the complete combustion rate in the internal combustion engine, and the combustion at a higher temperature Be brought.
