FUEL REDUCTION COMPOSITION FOR DIESEL INTERNAL COMBUSTION ENGINES

Abstract

Provided is a fuel-reducing composition for diesel internal combustion engines, which includes nanosized crushed nanomaterials and uses a lubricity improver to ensure sufficient dispersion. This allows for the cleaning of the combustion chamber and promotes complete combustion, which enhances output while reducing fuel consumption. By using the fuel-reducing composition for diesel internal combustion engines formed according to the preferred embodiment of the present invention, the size of the nanomaterials is limited, allowing for efficient cleaning of the combustion chamber without interfering with combustion. Without the use of surfactants for the dispersion of nanomaterials, a lubricity improver is employed to facilitate smooth dispersion while simultaneously protecting the combustion chamber of the engine and promoting complete combustion. Since the nanomaterials do not adhere to each other due to their size limitation and the use of the lubricity improver, combustion proceeds smoothly, leading to complete combustion and producing the desired effects.

DETAILED DESCRIPTION

[0038] Prior to describing a specific embodiment of the present invention, the figures shown in the specification may slightly exaggerate or simplify the size and shape of components thereof in order to more clearly describe the present invention.

[0039] In addition, the description of parts not related to the technical idea of this invention was omitted, and throughout this specification, the same or similar components were explained with the same reference number.

[0040] Since the terms and codes defined in the present invention are arbitrarily defined or selectively used by a user, an operator, and a drafter, these terms should be interpreted as meanings and concepts conforming to the technical idea of the present invention based on the overall contents of the present specification and should not be limited to the meaning of the terms themselves.

[0041] As a preferred embodiment of the present invention, 5 to 7 wt % of a nanomaterial consisting of celadonite, birnessite, lizardite, and carpholite is added to a butyl acetate solvent, and 2 wt % of a lubricity improver is included.

[0042] As another embodiment of the present invention, 5 to 7 wt % of the nanomaterial consisting of celadonite, birnessite, lizardite, and carpholite is added to the butyl acetate solvent, and a lubricity improver and a cetane improver is included.

[0043] As another additional embodiment of the present invention, 5 to 7 wt % of the nanomaterial consisting of celadonite, birnessite, lizardite, and carpholite is added to the butyl acetate solvent, and a lubricity improver, a cetane improver, an antioxidant, and a defoamer is included.

[0044] The aforementioned solvent, butyl acetate, is an organic compound of the formula CH.sub.3(CH.sub.2).sub.3O.sub.2CCH.sub.3 and is a colorless and combustible liquid.

[0045] The butyl acetate is an ester derived from n-butanol and acetic acid, found in various kinds of fruits, has a unique taste, and has a sweet smell of bananas or apples, and is widely used as an industrial agent.

[0046] The reason why the weight % of the nanomaterials are limited to 5-7 wt % is that when nanomaterials are inserted less than 5 wt %, cleaning of inside the cylinder is insignificant and does not have a significant effect on the dispersion of diesel fuel, so it is insufficient to induce complete combustion, [0047] and when the nanomaterials exceed 7 wt %, the cylinder is cleaned well, but rather, there is a problem of nanomaterials sticking together and interfering with the complete combustion, so the numerical limitation was made for the optimal effect.

[0048] The nanomaterial is consisted of celadonite, birnessite, lizardite, and carpholite, and it is appropriate that the particle size of each nanomaterial should be 40 to 80 nm.

[0049] If the nanomaterial particles are less than 40 nm, the cleaning effect is reduced, and if the nanomaterial particles are more than 80 nm, they become entangled with each other due to an increase in electrostatic force, and the inside of the combustion chamber gets damaged.

[0050] Out of the total 7 wt % of the nanomaterials, it is appropriate to consist of 2 wt % of celadonite, 1 wt % of birnessite, 2 wt % of lizardite, and 2 wt % of carpholite.

[0051] The Celadonite is a mica group mineral, a phyllosilicate of potassium, with iron in two oxidation states, aluminum, and it generally forms massive aggregates of prismatic crystals or dull clay masses.

[0052] The Birnessite is a manganese dioxide mineral and the primary manganese mineral species on the Earth's surface, and it generally forms as fine, poorly crystallized aggregates in soils, sediments, grain and rock coatings, as well as in marine ferromanganese nodules and crusts.

[0053] The Lizardite is a mineral of the tetragonal subgroup whose formula is Mg.sub.3(OH).sub.4, and is the most common type of mineral in the subgroup.

[0054] The Carpholite is a manganese silicate mineral of the formula Mn 2+Al.sub.2Si.sub.2O.sub.6(OH).sub.4, occurring as a thin prism or yellow cluster of needles, crystallized in an orthorhombic system.

[0055] The nanomaterials contain each of manganese, silicic acid, potassium, etc., and when the fuel with the fuel additive is sprayed by dissolving in the solvent in a nano-sized size, it enters together and cleans the interior of the combustion chamber, inducing the diffusion of the entire fuel to induce complete combustion

[0056] As for the lubricity improver, it is suitable to use one or mixture of fatty acid methyl ester (FAME), polyalkylene glycols (PAG), diethylene glycol monoethyl ether (DGME), or ethylene diamine.

[0057] The fatty acid methyl ester (FAME) is a kind of fatty acid ester, the polyalkylene glycols (PAG) is alcohol-based, and the diethylene glycol monoethyl ether (DGME) is ether-based.

[0058] The cetane improver is suitably one of 2-EHN (2-Ethylhexyl Nitrate), Di-tert-butyl Peroxide (DTBP), Ethyl Hexyl Nitrate (EHN), Tetraethyl Lead (TEL), fatty acid ester, or polymer nitrogen-containing compound.

[0059] The antioxidant suitably uses butylated hydroxytoluene (BHT), butylated hydroxyanisole (BHA), hindered phenol, or alkylated diphenylamine.

[0060] The butylated hydroxytoluene (BHT) is a phenolic antioxidant, the butylated hydroxyyanisole (BHA) and hindered phenols are phenolic antioxidant groups, and the alkylated diphenylamines is amine-based antioxidants.

[0061] The defoamer is formed to reduce bubbles for the complete combustion of fuel and is composed of one of polysiloxanes, polyether polymer, or petrolatum-based defoamer.

[0062] The polysiloxanes is silicon-based, and the petrolatum-based defoamer comprises compounds such as tributyl phosphate and tributyl citrate.

[0075] In order to find out the performance of the fuel-reducing composition for a diesel internal combustion engine formed by the preferred embodiment of the present invention, Embodiments 1 to 6 were formed and tested in comparison with the conventional fuel additives of Company B and Company H.

<Experiment 1> Fuel Reduction Rate Experiment

[0076] Fuel: High-sulfur diesel [0077] Test engine: Total 8 units of Caterpillar 50 ps (onshore generator) [0078] Additives: Fuel reduction compositions in Embodiments 1 to 6, Fuel Additives of Company B and Company H [0079] Measuring device: Flow meter tank level (error 3.71 L)

Experimental Method

[0080] 1) Using one test engine, 50 liters of fuel was added, and the engine was operated for 1 hour at 2000 rpm, and after operation, the remaining amount of fuel was measured to determine the fuel consumption before additive usea total of 33 liters was consumed.

[0081] 2) After diluting each additive to 2000:1, 50 liters were added, and the engine was operated for 1 hour at 2000 rpm, and after operation, the remaining amount of fuel was measured to determine the fuel consumption after additive use for each case.

Result of Experiment

TABLE-US-00001 Embodi- Embodi- Embodi- Embodi- Embodi- Embodi- Com- Com- ment 1 ment 2 ment 3 ment 4 ment 5 ment 6 pany B pany H Liters 25.2 25.4 24.8 25.2 24.3 24.2 30.1 32.3

[0082] Referring to the above experimental results, it can be seen that the consumption amount before use was 33 liters, whereas only 24 to 25 liters were used in Embodiments 1 to 6.

[0083] Especially, it was confirmed that there were almost no fuel savings with fuel additives from Company B and Company H.

[0084] In other words, Embodiments 1 to 6 of the present invention showed a fuel reduction rate of 25-30%, Company B showed a fuel reduction rate of 9%, and Company H showed a fuel reduction rate of about 2%.

[0085] Therefore, Embodiments 1 to 6 of the present invention were found to exhibit a high fuel reduction rate.

<Experiment 2> Measurement of Soot Emission Levels

[0086] FIGS. 1 to 4 show Embodiment 2, which has the best performance among the preferred embodiments of the present invention, and display the result of measuring soot after mixing with diesel in an engine of an old diesel vehicle

[0087] All four vehicles used in the test were older models that has been driven between 110,000 km to 220,000 km. Initially, they failed the inspection due to high exhaust emissions. However, after adding the fuel-reducing composition of Embodiment 2 of the present invention to the fuel, they all passed the test, as shown in FIGS. 1 to 4.

[0088] According to Experiment 2 above, it can be confirmed that the fuel-reducing composition for diesel internal combustion engines formed according to the preferred embodiment of the present invention can significantly reduce the exhaust emissions.

[0089] By using the fuel-reducing composition for diesel internal combustion engines formed according to the preferred embodiment of the present invention, the size of the nanomaterials is limited, allowing for efficient cleaning of the combustion chamber without interfering with combustion. Without the use of surfactants for the dispersion of nanomaterials, a lubricity improver is employed to facilitate smooth dispersion while simultaneously protecting the combustion chamber of the engine and promoting complete combustion. Since the nanomaterials do not adhere to each other due to their size limitation and the use of the lubricity improver, combustion proceeds smoothly, leading to complete combustion and producing the desired effects.

[0090] Although the present invention has been described based on preferred embodiments with reference to the accompanying figures, it is clear to those skilled in the art that various modifications may be made without departing from the scope of the present invention covered by the claims to be described below.
