Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is applicable to gasoline combustion engines such as automobiles, for example.
This invention relates to a combustion output device for an internal combustion engine that was developed to significantly reduce fuel consumption and prevent exhaust gas pollution by using water as part of the fuel.

In the past, various methods have been developed to use water in internal combustion engines such as automobiles, but most of them involve the addition of cold water. There is a method that uses additives such as methanol or hydrate, and supplies this in a spray state into the cylinder together with the supply of fuel and burns it.

However, no matter how you use the cold water addition method, it is impossible to increase the mixing ratio with fuel such as gasoline, or in other words, it is impossible to significantly reduce fuel consumption. This had drawbacks such as the inability to obtain normal operation of the engine.

Therefore, in the original patent application, the applicant sought to solve the above problems by refining two types of liquids, water and fuel oil, and air into high-temperature fuel gas, and optimizing the combustion conditions in the cylinder. However, in order to achieve this purpose, the present invention does not provide a combustion output device equipped with a new heater for water or steam. That is.

Hereinafter, the present invention will be described in detail according to an illustrated embodiment.

1 is water vapor, 2 is fuel oil, and the water vapor 1 is supplied to the heater 4 through a pipe 5.

Such a heater 4 communicates with a heating passage 6 for steam introduced through the pipe 5 and an exhaust pipe 7 through an exhaust gas inlet 8 and an exhaust gas outlet 9, and constantly receives high temperature gas sent from the exhaust pipe 7. The heating passage 6 is installed inside the exhaust gas room 10, and the wall surface constituting the heating passage 6 is heated by the exhaust gas in the room 10. The device that comes into contact with high heat conducts heat and is kept at a high temperature at all times.

Therefore, in the process of passing through the heating passage 6 of the heater 4, the water vapor touches the high-temperature wall of the passage 6 and passes through the high-temperature atmosphere, absorbing the high heat and being further heated to a high temperature. It becomes a nearly colorless gas.

Further, inside the heating passage 6, filters 11 made of a mesh are provided in multiple stages so as to partition the passage 6, and water vapor passes through the filter 11 while being heated.

Therefore, by passing through the filter 11, relatively large particles in the water vapor are effectively removed by the fine pores of the filter 11, and only the purified gas can be screened out first, thereby reducing the gasification of the water vapor. This will contribute to the promotion of the project.

In addition, the filter 11 is made of a material such as iron that has a strong affinity for oxygen, and when the heated steam passes through the filter 11, a catalytic reaction is caused, and a part of the oxygen in the steam is removed, making it more suitable for combustion. It is refined to a pure state.

Further, the filter 11 also becomes red hot due to heat conduction by the exhaust gas in the room 10, and when the water vapor is brought into contact with it when passing through the filter, the gasification of the water vapor is promoted and the catalytic reaction is aroused.

Therefore, in the process of passing through the heater 4 described above, the water vapor 1 absorbs the high heat of the exhaust gas and is heated in stages, and is also subjected to the filtering action of the filter 11, and further becomes a heated gas whose molecules are excited. Then, it is supplied to, for example, the heating mechanism of the cylinder head, which will be described later, and further thermal decomposition is promoted.

Reference numeral 12 denotes a heater for the fuel oil 2, and the fuel oil 2 is always heated through the heater 12 via a pipe 13.

The heater 12 also uses the high-temperature exhaust gas generated during the explosion as a heat source, and when the heating oil passes through the heater 6, it absorbs the high heat of the exhaust gas and becomes heated vaporized gas, which passes through the pipe 14 to the carburetor 15. supplied to

Reference numeral 16 denotes a cylinder head section made of a metal material, and the head section 16 is provided with a water communication path 17 and an air communication path 18 formed directly inside the head section 16. The passage 17 is connected to the heater 4 via a pipe 19,
The heated steam heated by the heater 4 and aroused in a catalytic reaction is introduced into the communication passage 17 through the pipe 19.

It is known that the cylinder head portion 16 temporarily reaches a high temperature of approximately 2000°C due to combustion heat generated during an explosion.
During the passage of the heated steam introduced into the communication passage 11 in the communication passage 17, the heated steam momentarily touches the high-temperature metal wall of the head part 16 forming the communication passage 17, making it extremely easy to mix with the fuel oil. The water is decomposed into a gaseous gas that is easily combustible, and the water gaseous gas is supplied through a nozzle 20 from the carburetor 15 to an intake pipe 22 that communicates with each combustion chamber 21 of the cylinder.

Further, the air communication path 18 introduces air from the outside,
Similarly, the air is heated in the process of passing through the communication passage 18, and is supplied as high-temperature heated air to the combustion chamber via the pipe 23.

Thus, the gaseous water excited into a reactive state by contact with the high-temperature metal wall of the cylinder head section 16 is ejected from the nozzle 20 into the suction pipe 22, where it is mixed with the heated air before being heated and vaporized. It joins with the mixed gas of the three to become a mixed gas of the three, which is sucked into or ejected into each combustion chamber 21 and exploded and burned.

In particular, the mixture of these three gases is in a highly excited state where water molecules are more likely to react, so the mixed combustion ratio with fuel oil can be increased to +1], increasing the combustion effect. Not only this, but also a large amount of fuel oil can be saved, and the conditions for complete combustion are established, making it possible to effectively prevent exhaust gas pollution.

As described above, the heater according to the present invention has a heating passage installed in a room that is always filled with high-temperature exhaust gas, and the heating passage is made up of the exhaust gas in the room. The wall surface is maintained at a high temperature to heat the water vapor, and a thermal filter for permanent steam filtration is disposed in the heating passage to filter out and heat the water vapor. In order to improve the mixing ratio of water and fuel oil, we can provide a heating structure that makes full use of the exhaust gas generated during explosive combustion, and is extremely effective in streamlining and downsizing equipment. In addition to being able to contribute to the gasification of water, the internal structure of the thermal filter promotes the fragmentation of water vapor particles and high molecularization, which can greatly contribute to the thermal decomposition of water that is more suitable for combustion. It is.

In the embodiment, the heater 4 is used as a steam heater, but the above effect can also be obtained by directly supplying water to the heater 4. If used in combination, the above effects will be further enhanced.

In addition, the heater 4 can be used not only as a heater for water or steam, but also as a heater for fuel oil. The mixture can also be used as a heater, and its practical application range is wide-ranging.
