Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fuel saving device for an internal combustion engine equipped with an ignition plug, and more specifically, the present invention relates to a fuel saving device for an internal combustion engine equipped with a spark plug, and more specifically, to generate hydrogen by effectively utilizing the exhaust heat of an internal combustion engine using gasoline or the like as fuel. Although it is possible to significantly reduce fuel consumption by mixing hydrogen into the fuel of an internal combustion engine and using it as part of the fuel,
Not only can the rated horsepower be maintained, but the temperature of exhaust heat can be lowered during the hydrogen generation process, increasing the noise reduction effect.
Furthermore, the present invention relates to a fuel saving device for an internal combustion engine equipped with a spark plug, which is capable of reducing exhaust gas emissions as well as reducing fuel consumption, thereby suppressing noise pollution and exhaust gas pollution as much as possible. It is something.

Internal combustion engines that run on gasoline and other fuels are compact and have excellent performance, so they are widely used as power sources for automobiles and various other machines, contributing greatly to the development of industry. The amount of fuel used in internal combustion engines has reached a staggering amount, and most fuels such as gasoline are imported from overseas, so reducing the amount of fuel used in internal combustion engines is a major challenge from the national economic perspective. It is said that Therefore, various fuel saving devices for use in internal combustion engines have been proposed, but all of these devices require major changes to the structure of the internal combustion engine itself, making it easy to implement. The reality is that this is not the case. Therefore, there is a strong demand for a fuel saving device with a simple structure that can be easily used in existing internal combustion engines, especially in these days when there is a high social demand for energy saving.

In view of the above-mentioned circumstances, the present invention was created based on a completely new concept in order to meet these demands. A steam generation pipe whose one end is connected to a water storage tank is disposed in the exhaust gas pipe, and the other end of the steam generation pipe is connected to one end of a reaction tube disposed inside the exhaust manifold at a position close to the exhaust hole of the cylinder. and the other end of the reaction tube is connected to the suction tube of the vaporization tube,
By mixing the hydrogen generated in the above reaction tube into the intake fuel gas of the cylinder, it is possible to effectively utilize the exhaust heat of the internal combustion engine and use the generated hydrogen as part of the fuel. Although it has a simple structure that can be easily installed on the engine, it can significantly reduce fuel consumption, maintain the rated horsepower, and reduce exhaust heat in the process of generating hydrogen. The heat exchange between the water and the water in the steam generation pipe lowers the temperature and enhances the noise reduction effect, which, together with the reduction in fuel consumption, relatively reduces the amount of exhaust gas emissions, reducing noise pollution and
It is an object of the present invention to provide a fuel saving device for an internal combustion engine with an ignition plug that can suppress exhaust gas pollution as much as possible.

An embodiment in which the configuration of the present invention is installed in a fuel supply system for an ordinary automobile will be described. In the figure, 1 is an internal combustion engine equipped with a carburetor 3 and an air cleaner 4 on the intake hole side of a cylinder 2, and an exhaust manifold 6 is provided at one end of the internal combustion engine 1 to cover an exhaust hole 5 of the cylinder 2. I'm here.

7 connects the proximal end to the above exhaust manifold 6 by means of a coupler 8.
The exhaust gas pipe 7 is connected to the exhaust gas pipe 7, and the tip side of the exhaust gas pipe 7 is opened to the outside air via a silencer 9.
It is designed to release combustion exhaust gas. Inside the exhaust gas pipe 7, a steam generation pipe 12 is disposed, one end of which is connected to the water storage tank 11 via an adjustment cock 10, facing the exhaust manifold 6. The other end of the steam generation pipe 12 is It extends from a position near the connector 8 through the pipe wall of the exhaust gas pipe 7, and is connected to one end of the reaction tube 13, which is disposed inside the exhaust manifold 6, and protrudes from the exhaust manifold 6. The reaction tube 13 is formed by bending a tubular body made of iron (Fe) into a meandering shape, and is arranged at a position close to the exhaust hole 5 . The other end of the reaction tube 13 passes through the side wall of the exhaust manifold 6 and communicates with the filter 15, and is further connected to an intermediate portion of the intake pipe 14 that communicates the air cleaner 4 and the vaporization tube 3. There is.

In the above-described configuration, when starting the internal combustion engine 1, the engine 1 can be started easily as before by first turning on a key switch (not shown). It mixes with the vaporized fuel, becomes a mixed gas, and is sucked into the cylinder 2, and after explosive combustion, becomes a high-temperature exhaust gas that passes through the exhaust manifold 6 and is released into the outside air from the exhaust gas pipe 7.

Then, if the adjustment cock 10 is opened and the required amount of water flows into the steam generation pipe 12, the steam generation pipe 12 will be
Since the water is heated by the exhaust gas passing through the exhaust gas pipe 7, the water exchanges heat with the exhaust gas and immediately becomes water vapor, which flows into the reaction tube 13 connected to the other end.

In addition, at this time, the temperature of the exhaust gas decreases by the amount taken by water, and the volume of the exhaust gas decreases, so that the exhaust sound from the exhaust gas pipe 7 becomes low due to the silencing effect.

On the other hand, since the reaction tube 13 is located close to the exhaust hole 5, it is directly heated to a red-hot state by the extremely high temperature exhaust gas immediately after combustion in the cylinder 2, so that the water vapor is It reacts with reaction tube 1- and is thermally decomposed. That is, the reaction tube 13j is made of iron (Fe), which has chemical properties that are easily oxidized, and a reaction of 3Fe+4HzO-+Fe30-b+4H occurs, and iron becomes 4-iron oxide and hydrogen (Hz). occurs.

The other end of the reaction tube 13 is connected to an intermediate portion of the intake pipe 14 that communicates the air cleaner 4 and the vaporization tube 3, so that hydrogen is transferred to the filter 15 by the negative pressure of the intake air taken into the cylinder 2. Dust is removed from the intake pipe 1.
4, mixed with the air and fuel mixture gas, and sucked into the cylinder 2. Therefore, the hydrogen sucked into the cylinder 2 combines with oxygen to generate strong explosive force, so even if the amount of fuel in the mixture is reduced, the internal combustion engine 1 continues to operate at high output. As a result, fuel consumption can be significantly reduced compared to conventional methods. Furthermore, since hydrogen is generated by effectively using exhaust heat, there is no need to install a separate complicated hydrogen generation device, and the structure is extremely simple. Furthermore, since hydrogen is used as part of the fuel, the above fuel consumption is reduced. Together with the reduction in emissions, it is possible to relatively reduce the amount of exhaust gas emissions, and to that extent, it is possible to suppress the emission of harmful nitrogen oxides and other substances contained in the exhaust gas into the outside air. can.

In short, the present invention provides an exhaust gas pipe in which the proximal end communicates with the exhaust manifold and the distal end opens into the outside air.
A steam generation pipe is installed with one end connected to a water storage tank.
The other end of the steam generation pipe is connected to one end of a reaction tube disposed inside the exhaust manifold in a position close to the exhaust hole of the cylinder, and the other end of the reaction tube is connected to the suction pipe of the vaporization tube. Since the hydrogen generated in the reaction tube is mixed into the intake fuel gas of the cylinder through communication, an extraordinary first-order effect is achieved compared to conventional systems of this type.

(1) Hydrogen generated by effectively utilizing the exhaust heat of the internal combustion engine is mixed into the fuel and used as part of the fuel, so that the mist of gasoline that comes out of the vaporizer is vaporized by the hot hydrogen. Because it enters the cylinder as a gas, it can significantly reduce fuel consumption while still maintaining the rated horsepower.

(2) By exchanging exhaust heat with water during the hydrogen generation process, the temperature of the exhaust heat can be lowered by that amount, and as a result, the noise of exhaust gas emitted from the exhaust gas pipe to the outside air can be reduced. It is possible to reduce the sound level and suppress noise pollution.

(3) Together with the reduction in fuel consumption, it is possible to relatively reduce the amount of exhaust gas emissions, and the amount of harmful nitrogen oxides contained in the exhaust gas is released to the outside air by the amount of the reduction. It can suppress emissions and contribute to the prevention of exhaust gas pollution.
