In addition to improving the hardware structure, some users also try to use lean fuel mixture to reduce CO and HC. And it is easy to cause the problem of slowing down after combustion. Therefore, the industry has developed and designed a technology called CVCC (Compound Vortex Controlled Combustion), which will first ignite with a richer fuel mixture, and then Burns with a leaner fuel mixture. However, the aforementioned CVCC requires specialized engine systems and technologies, resulting in a high final cost of the vehicle.

For the convenience of your examination committee to the purpose of the present invention, technical characteristics and effects thereof, do further understanding and understanding, hereby give examples to cooperate with the drawings, and describe in detail as follows:

The invention relates to a concentrate containing nano-precious metals to improve the combustion efficiency of gasoline and diesel, and its additive and its preparation method. In practice, the additive can be added to the fuel tank of a vehicle first, and then gasoline or diesel is added to the fuel tank. in the fuel tank so that the additive can be mixed with the gasoline or diesel. After the applicant's test, 150 milliliters (mL) of the additive can be mixed into 50 liters to 150 liters of gasoline or diesel oil, and the effect of improving the combustion efficiency described later can be achieved.

In one embodiment of the present invention, the additive is at least composed of a petroleum distillate (or naphtha) and a concentrate, and the weight percentage of the concentrate in the additive is 2% to 10%. %, the petroleum distillate accounts for the remaining weight percentage of the additive (eg: 90%~98%). However, it is specially mentioned here that other materials can also be added to the additive according to the needs of use. At this time, the weight percentage of the petroleum distillate will decrease accordingly, and it can be lower than the aforementioned value (90%~98%). In addition, the concentrate includes nano-precious metal particles, nano-zinc oxide particles and a dispersant (or auxiliary agent), wherein the nano-precious metal particles are mainly used to improve the combustion efficiency of gasoline/diesel, and at least contain nano-particles. The nano-sized gold particles; the nano-zinc oxide particles are photocatalysts and have a catalytic effect, which can promote the reaction rate of the additive to increase; the dispersant can not only make the nano-precious metal particles and nano-zinc oxide particles evenly distributed in the concentrate In addition, it can also emulsify the concentrate into a solution that can be mixed into the petroleum distillate to achieve oil-water compatibility.

The efficacy and weight percentage of the nano-precious metal particles in the concentrate will be described. First, the nano-precious metal particles include nano-gold (Au) particles, and the weight percentage of the concentrate is 50-350 ppm, wherein, Based on the unique potential characteristics of nano-gold particles, it has a strong adsorption force for oxygen, and can be used as a catalyst, and the nano-gold catalyst can react at room temperature without being affected by water vapor effect. Therefore, after the additive of the present invention is mixed into gasoline or diesel, the fuel flowing into the internal combustion engine of the vehicle (that is, the gasoline or diesel that has been mixed with the additive) can be captured based on the strong oxidizing properties of the gold nanoparticles. The oxygen in the air or gasoline/diesel can effectively increase the oxygen content in the fuel to help the aforementioned fuel have a better combustion effect.

Secondly, the nano-precious metal particles also include nano-palladium (Palladium, Pd) particles, and the weight percentage of the concentrate is 50-350 ppm, wherein, palladium has excellent hydrogen absorption ability, and it is made into nano-scale After the particles, the color will change from silver to black, so it is called "palladium black". At this time, due to the size effect and the large surface area effect, the palladium will be transformed from an inert substance to a catalyst with excellent activity , Because the reflectivity of nano-palladium particles to light energy and heat energy is extremely low, usually less than 1%, that is, the diameter of about a few microns can be completely extinct, and it becomes a high-efficiency energy conversion material. In addition, since platinum (Platinum, also known as platinum) and rhodium (Rhodium, Rh) have the same characteristics as palladium, and have extremely low reflectivity to light energy and thermal energy, therefore, in other embodiments of the present invention Among them, the concentrate can also include nano-platinum particles and nano-rhodium particles, wherein the nano-platinum particles will account for 50-250 ppm of the concentrate by weight; the nano-rhodium particles will account for the The weight percentage is 30~120ppm.

It is particularly mentioned here that gasoline (Gasoline) is a part of crude oil distillation products, mainly hydrocarbons composed of five carbons to ten carbons, and its structure includes paraffinic hydrocarbons (that is, chain hydrocarbons). ), cyclic hydrocarbons (Naphthenes) and aromatic hydrocarbons (Aromatics), etc. In addition, in order to improve the quality of gasoline so that it can have a better combustion effect when it is burned in the combustion chamber of the vehicle, the industry has also developed the cyclization of long-chain hydrocarbons to form cyclic hydrocarbons. It is the practice of forming aromatic hydrocarbons into aromatic hydrocarbons after cracking, polymerization and dehydrogenation. However, after the additive of the present invention is mixed into gasoline or diesel, by virtue of the properties of nano-palladium particles and nano-platinum particles, the fuel flowing into the internal combustion engine can be cracked from the original long-chain hydrocarbon fuel molecules into The fuel molecules of short-chain hydrocarbons can stimulate the maximum energy efficiency of the fuel, and at the same time, its hydrogen absorption capacity can also effectively increase the hydrogen content in the fuel, so that the aforementioned fuel has better combustion efficiency, not only The internal combustion engine can generate more power, and the pollutants contained in the fuel can be eliminated due to better combustion efficiency, and will not remain in the exhaust gas emitted by the internal combustion engine.

In addition, the nano-precious metal particles also include nano-cerium (Cerium, Ce) particles, and the weight percentage of the concentrate is 50-350 ppm. Nano-noble metal particles can maintain the expected efficacy (such as: oxygen capture, hydrogen absorption, etc.). In addition, ruthenium (Ru) can achieve properties similar to those of cerium (Ce). Therefore, in other embodiments of the present invention, the concentrate can further include nano-ruthenium particles, and the nano-ruthenium particles The weight percentage of the concentrate will be 30~250ppm.

The nano-zinc oxide particles will account for 0.5% to 2.5% by weight of the concentrate, and after deducting all nano-precious metal particles and nano-zinc oxide particles, the rest of the concentrate is dispersant ( About 97.3%～99.4%), moreover, if this concentrate also adds other materials separately, then the weight percentage occupied by this dispersant will also decrease accordingly, again, in this embodiment, this dispersant can be octanol Homogeneous mixture of (OCTANOL) and castor oil (CASTOR OIL) or derivatives thereof. The main function of the dispersant is to make the concentrate have both lipophilicity and hydrophilicity, so that it can be fully mixed into the petroleum distillate and gasoline/diesel, and will not form a separate state due to incompatibility. However, in other embodiments of the present invention, the type of the dispersant is not limited. It can be a mixture of petroleum solvent, biological extract and surfactant, as long as it is sufficient to make the concentrate achieve the aforementioned oil-water compatibility. It is the so-called dispersant in the present invention.

The preparation method of the concentrate is hereby described, please refer to Figure 1. The preparation method includes the following steps: (101) mixing the dispersant and the nano-zinc oxide aqueous solution into a first solution, wherein the dispersant and the nano-zinc oxide aqueous solution are mixed into the first solution in a ratio of 4:1; in the In an embodiment, the nano-zinc oxide aqueous solution is at least composed of nano-zinc oxide powder, water and a polyacrylic acid derivative, wherein the nano-zinc oxide will be dispersed in the nano-zinc oxide aqueous solution, and will occupy the nano-zinc oxide solution. The weight percentage of the zinc aqueous solution is 5%; (102) the first solution is stirred for the first time, and the first stirring time is 12 to 16 hours; in this embodiment, the first solution will be carried out at a rotating speed of 500 to 1500 rpm under the environment of room temperature stirring; (103) The stirred first solution is allowed to stand, and the standstill time is 72 to 96 hours, until the bottom in the aforementioned first solution forms a precipitation colloid A1, and at the same time, above the precipitation colloid forms a transparent a second solution A2 (as shown in Figure 2), and the second solution A2 will contain nano-zinc oxide particles, wherein the original first solution of the precipitate (such as: polyacrylic acid derivatives) and water Both will be located in the lower layer (ie, the area of the precipitation colloid), and the oily liquid and its internal components (eg: nano-zinc oxide particles) will be located in the upper layer (ie, the area of the second solution); (104) Take out the second solution A2, and directly add nano-precious metal particles or add nano-precious metal solution in the second solution A2 to form a third solution, wherein the nano-precious metal can be gold, palladium , cerium, platinum, ruthenium, rhodium, etc.; in addition, a small amount of precious metal solution is an aqueous solution, and still has the nature of oil-water compatibility, and can be directly mixed into the second solution A2; and (105) The third solution is stirred for the second time, and after the second stirring time is 4 hours, the concentrate will be formed; in this embodiment, the third solution will be in the room temperature environment, Stir at 500 to 1500 rpm.

Finally, the concentrate is mixed with the petroleum distillate to form the additive of the present invention, and since the concentrate contains a large amount of dispersant, it can be fully mixed into the petroleum distillate, and the additive can also be mixed into steam/oil. In this embodiment, after the concentrate is mixed with the petroleum distillate, it will be left to stand for at least 24 hours, so that a very small amount of non-uniformly miscible precious metal particles can settle to the bottom to form a supernatant liquid and a precipitation layer , Hereafter, take out the upper layer liquid after standing, then the above-mentioned upper layer liquid is the additive, so, when the vehicle uses gasoline/diesel oil containing the additive, it will be able to avoid the accumulation of sediment in the oil pipe, causing the oil pipe to block the situation. As mentioned above, since the preparation method of the concentrate includes steps such as stirring and standing, the nano-zinc oxide particles and nano-precious metal particles can be uniformly dispersed in the concentrate. After the additive of the invention is added to gasoline or diesel, the nano-precious metal particles in it, such as nano-gold particles, nano-palladium particles, etc., can effectively increase the combustion support in the fuel (ie, gasoline or diesel with additives already mixed) components (such as oxygen) and combustible components (such as hydrogen), so that gasoline and diesel can achieve the best combustion efficiency, not only can the internal combustion engine generate the maximum power, but also the pollutants contained in gasoline and diesel can be Due to the best combustion efficiency, it will disappear completely and will not remain in the exhaust gas emitted by the internal combustion engine. Only in this way can it actively achieve the reduction of the use of fossil fuels and effectively achieve the goal of low pollution or zero pollution exhaust emissions.

According to the above, it is only a preferred embodiment of the present invention, but the scope of the rights claimed by the present invention is not limited to this. The equivalent changes that can be easily considered should all belong to the protection scope of the present invention.
