Description

Composition for soot-particle and fuel reduction

The present invention relates to a composition capable of significantly reducing the soot discharged from the engine by mixing it with the cooling water of the engine.

Engines commonly found around life are devices that obtain desired output by using fossil fuels such as gasoline as a driving force. The most important task in research on such an engine is to enable the use of minimum fuel with maximum fuel efficiency. In addition, recent studies have been conducted to reduce pollutants emitted by combustion in engines due to global warming caused by greenhouse gas emissions and air pollution caused by fine dust.

These studies specifically include design change of the engine itself, improvement of fuel purity, development of fuel additives, etc. Furthermore, studies are being actively conducted on auxiliary means that indirectly affect the engine such as coolant.

The coolant originally aims to prevent the temperature of the engine from becoming too high by absorbing heat generated during the driving process of the engine. However, in recent years, research on a technology for reducing the exhaust gas exhausted from the engine by adding an additive to the coolant that indirectly affects the engine operation to prevent incomplete combustion, etc. has been actively conducted. For example, Korean Patent Registration No. 10-1815015 provides a composition for reducing emissions to be mixed with cooling water, but even in this case, there is a limit in reducing the emission of hydrocarbons.

Korean Patent Registration No. 10-1010935 Korean Patent Registration No. 10-1815015

It is an object of the present invention to provide a smoke reduction composition capable of significantly reducing the emission of pollutants discharged from internal combustion engines such as nitrogen oxides and carbon monoxide, especially unreacted hydrocarbons.

The exhaust emission reduction composition according to the present invention includes silicon carbide particles, silica particles, and tourmaline particles.

The exhaust emission reduction composition according to an embodiment of the present invention may include one or more selected from graphite or boron.

The soot reduction composition according to an embodiment of the present invention may further include one or more selected from aluminum oxide, zeolite, and silicon dioxide.

The exhaust emission reduction composition according to an embodiment of the present invention may include 200 to 400 parts by weight of silicon carbide particles relative to 100 parts by weight of the tourmaline particles.

The soot reduction composition according to the present invention has the advantage of being able to significantly reduce the discharge of soot, specifically, hydrocarbons, which are discharged from the internal combustion engine by simultaneously including silicon carbide particles, silica particles and tourmaline particles.

Hereinafter, the exhaust emission reduction composition according to the present invention will be described in detail by examples. However, the following examples are for illustrative purposes only, and the present invention is not limited to the following examples. In addition, terms used in the present invention are based on the general knowledge level of a person skilled in the art, unless otherwise defined in the present invention, and descriptions of widely known technologies that obscure the essence of the present invention will be omitted.

The present invention relates to an emission reduction composition comprising silicon carbide particles, silica particles and tourmaline particles.

When the soot-reducing composition according to the present invention is mixed with the cooling water for an internal combustion engine, there is an advantage of being able to significantly reduce soot substances in exhaust gas discharged from the internal combustion engine. Specifically, when an internal combustion engine is operated after mixing the smoke reduction composition according to the present invention with cooling water for an internal combustion engine, surprisingly, there is an advantage of remarkably reducing the emission of nitrogen oxides or carbon dioxide, especially unreacted hydrocarbons. .

At this time, the term soot in the soot reduction composition according to the present invention means hydrocarbons, carbon monoxide, nitrogen oxides, and carbon dioxide, and the internal combustion engine is a device that generates energy by burning fuel inside, specifically used for automobiles or ships. It may be an internal combustion engine, but is not limited thereto. In addition, the unreacted hydrocarbons collectively refer to compounds having carbon-hydrogen bonds that cannot be completely burned in an internal combustion engine.

That is, the soot reduction composition according to the present invention has the advantage of being able to significantly reduce unreacted hydrocarbons, which is one of the pollutants discharged from the internal combustion engine, by simultaneously including silicon carbide particles, silica particles, and tourmaline particles. These hydrocarbons are one of the greenhouse gases that cause global warming, and have a high global warming index compared to carbon dioxide, and thus have the advantage of preventing global warming by reducing these unreacted hydrocarbons. Specifically, the diameters of the silicon carbide particles and the silica particles may be 1 to 200 μm, specifically 10 to 100 μm, independently of each other, and the tourmaline particle diameter may be 0.1 to 3 μm.

Specifically, the smoke reduction composition according to an embodiment of the present invention may include 200 to 400 parts by weight of silicon carbide particles relative to 100 parts by weight of tourmaline particles. When the exhaust emission reduction composition according to an embodiment of the present invention includes tourmaline particles and silicon carbide particles in the above range, the emission of unreacted hydrocarbons can be reduced by up to 95% compared to the case where the emission reduction composition is not used. There is an advantage.

In addition, due to the synergistic effect of not only reducing unreacted hydrocarbons, but also by increasing the thermal conductivity of the entire cooling water after mixing with cooling water by using a small amount of tourmaline particles, it has the advantage of efficiently performing heat absorption, which is the original function of the cooling water. As a result, the smoke prevention effect of the internal combustion engine is also excellent.

The exhaust emission reduction composition according to an embodiment of the present invention may include at least one selected from graphite and boron. When at least one selected from graphite and boron is added to the cooling water, it is seen that the combustion of the fuel of the internal combustion engine is promoted to assist the complete combustion of the fuel, thereby increasing the combustion efficiency. Specifically, when the soot reduction composition according to an embodiment of the present invention contains at least one selected from graphite and boron together with the above-described silicon carbide, tourmaline particles, and silica particles, it causes a unique synergistic effect in the internal combustion engine. There is a characteristic that combustion of fuel is accelerated, and as a result, there is an advantage of further reducing the emission of soot substances such as carbon monoxide by promoting such combustion.

In addition, the smoke reduction composition according to an embodiment of the present invention may include 16 to 32 parts by weight of each of the graphite and boron composition relative to 100 parts by weight of tourmaline particles, and the above-described complete combustion acceleration effect may be maximized in this range. . In this case, the graphite and boron are not limited if they are in the form of particles that can be uniformly mixed with the cooling water, but preferably, graphite and boron may have a diameter of 1 to 200 µm, specifically, 10 to 100 µm, independently of each other. .

In addition, when the soot reduction composition according to an embodiment of the present invention includes both graphite and boron together with silicon carbide, tourmaline, and silica particles in the above numerical range, nitrogen oxides, carbon monoxide, and unreacted hydrocarbons as described above. In addition to reducing the emission of chemicals, it is possible to reduce the emission of nitrogen oxides by a certain amount, which may be more efficient in reducing greenhouse gas emission.

The soot reduction composition according to an embodiment of the present invention may further include one or two or more selected from aluminum oxide, zeolite and silicon dioxide, and specifically, one or two or more selected from aluminum oxide, zeolite and silicon dioxide. It may contain metal particles. As observed by the experiment, it is observed that the agglomeration of the soot-reducing composition is significantly reduced by using this, and it is judged that the reduction of gas emission is improved by the effect induced by such a decrease in agglomeration and uniform dispersion.

Specifically, the soot reduction composition according to an embodiment of the present invention may include 15 to 20 parts by weight of one or two or more metal particles selected from aluminum oxide, zeolite, and silicon dioxide based on 100 parts by weight of tourmaline, and within the cooling water in this range There is an advantage of preventing agglomeration of metal particles and maximizing combustion efficiency.

The soot reduction composition may be added differently depending on the type of internal combustion engine used and the amount of cooling water, but may be preferably mixed with 30 to 300 g per 100 ℓ of cooling water based on a vehicle. Further, the mixing of such a smoke reduction composition is not limited when a means for mixing the smoke reduction composition with the cooling water included in the internal combustion engine is used, but it is mixed with water or a commercially available antifreeze and added in the form of a dispersion, or in the cooling water. It can be introduced in the form of a dissolvable capsule. The capsule used at this time is not limited if it is a material that can be dissolved in the cooling water, but may be specifically gelatin, collagen, or a mixture thereof.

Preferably, the smoke-reducing composition according to an embodiment of the present invention may be mixed with alkaline ionized water and dispersed, and then mixed with cooling water. At this time, alkaline ionized water is also referred to as alkaline electrolyzed water, and is water obtained by applying an electric force to ordinary bottled water, tap water, or groundwater, and water collected at the cathode electrode is called alkaline ionized water. When the soot-reducing composition is dispersed using such alkaline ionized water and then mixed with cooling water, the soot-reducing effect of the soot-reducing composition according to an embodiment of the present invention can be exhibited for a long period of time, and further, the life of the cooling water itself is extended. It has the advantage of preventing damage to the vehicle due to corrosion even in long-term use. In this case, the alkali ionized water may be added to the cooling water by mixing in a weight ratio of the smoke reduction composition: alkaline ionized water in a ratio of 2:5 to 1:2.

In addition, the soot reduction composition according to an embodiment of the present invention may be added to the cooling water after mixing with an amphipathic solvent. When the soot-reducing composition and the amphiphilic solvent according to an embodiment of the present invention are mixed and then added to the cooling water, the above-described soot reduction efficiency is further increased, and the soot-reducing composition is easily dispersed in the cooling water, Furthermore, there is an advantage of preventing the formation of scale by cooling water after the addition of the smoke reduction composition. Specifically, such an amphiphilic solvent is not limited if it is an amphiphilic solvent in the usual sense, but specifically propylene glycol monomethyl ether acetate, dipropylene glycol monomethyl ether, propylene glycol neobutyl ether, dipropylene glycol neobutyl ether, It may be one or two or more selected from dipropylene glycol monomethyl ether acetate, tripropylene glycol methyl ether, and 1,3-butanediol diacetate. In addition, such an amphiphilic solvent may be mixed with 10 to 1000 parts by weight, specifically 20 to 300 parts by weight, based on 100 parts by weight of the smoke-reducing composition. In the above range, it is possible to maximize the anti-scale effect without deteriorating the emission reduction effect.
