Description

The present invention relates to a method for improving fuel efficiency, a method for producing fuel for automobiles, and a fuel for automobiles.

Traditionally, companies have been competing to study how to improve the fuel efficiency of automobiles. In addition, various approaches have been taken to improve fuel efficiency, such as internal combustion engines and other parts, vehicle weight, tires, and fuel.

On the other hand, in addition to improving fuel efficiency, each company is also researching how to reduce the emissions of carbon dioxide and other exhaust gas components generated by the operation of internal combustion engines in consideration of the environment. It should be noted that reducing the amount of exhaust gas components such as carbon dioxide and improving fuel efficiency are not uniquely equal.

For example, Patent Document 1 is an attempt to improve fuel efficiency. The prior art of Patent Document 1 is to improve combustion efficiency and improve fuel efficiency by adding a fuel additive to petroleum fuel in a diesel engine.

Further, there is, for example, Non-Patent Document 1 as an attempt to reduce the amount of exhaust gas components emitted. Non-Patent Document 1 describes an old industrial engine called the Petter engine as described in N. Diesel fuel infused with a diesel fuel improver 1.27 to 6.35% by volume (= 1.0 to 5.0 w / v%) consisting of N-dimethyldodecylamine is put in, and the industrial engine is operated alone. This is a measurement of the amount of exhaust gas components emitted. However, the test results show no favorable effect and no change in HC and CO, CO2, NOx emissions, but only conclude that they do not have a negative effect.

However, prior art such as Patent Document 1 cannot reduce carbon dioxide even if an additive is added to petroleum fuel, a fuel reduction device is attached, or an exhaust gas reduction device is attached. If it burns completely, carbon dioxide will increase, and if the engine is in good condition, carbon dioxide will increase.

Further, it can be said that the prior art such as Non-Patent Document 1 does not reduce the exhaust gas component and has no effect of improving the fuel efficiency, but even if the exhaust gas component is reduced, that and the improvement of the fuel efficiency are uniquely equal. However, it cannot be said that this method improves fuel efficiency.

Furthermore, the test results for conventional exhaust gas were carried out by the self-report of the company, and as reported by newspapers, fraud was also carried out. For example, there was a case where there was a difference of 10 times or more between the amount of exhaust gas component announced by a certain company and the actual amount of exhaust gas component. Therefore, it must be said that there is doubt about the effect of reducing exhaust gas components such as carbon dioxide by the conventional method.

Furthermore, the conventional fuel consumption measurement method is generally 10/15 mode driving or JC08 mode driving. These do not run on actual public roads, but the test vehicle is placed on the rollers of the measuring instrument at the test site, and the tires are rotated on the spot to measure the fuel consumption. However, it is a well-known fact that these fuel consumption measurement methods have a large gap from the fuel consumption actually driven on public roads, as reported by newspapers.

Moreover, it cannot be determined whether or not the fuel efficiency is improved only by operating only the internal combustion engine and measuring the exhaust gas as in Non-Patent Document 1. Originally, in order to determine whether or not fuel efficiency is improved, a road test in which a vehicle travels on an actual public road is indispensable.

Therefore, the inventor of the present application has been diligently researching the improvement of fuel efficiency by conducting a demonstration test using a large number of vehicles and a huge amount of time. At the same time, we are continuing research on reducing exhaust gas components such as carbon dioxide.

On the other hand, in the past, the inventor has been conducting eco-driving education for drivers for about 20 years in order to save fuel consumption, but fuel consumption can be reduced by at most 1% to 2%. In addition, even if a digital tachograph is installed and managed, there is almost no difference in fuel efficiency with a veteran driver who eco-drives.

Therefore, as a result of diligent research on a method for reducing carbon dioxide generation and improving fuel efficiency, the inventor of the present application has added a fuel oil injection agent composed of dimethylalkyl tertiary amine to petroleum fuel from 0.5 to 0.5. He invented a fuel for an internal combustion engine in which 1% by volume was injected (see Patent Document 2).

In addition, the inventor continued his research even after filing this patent application, and succeeded in enhancing the fuel efficiency improving effect as compared with the previous invention, leading to the present invention. An object of the present invention is to reduce fuel consumption and carbon dioxide in driving an automobile as compared with the conventional case.

In one aspect of the method for producing petroleum fuel according to the present invention, prior to charging a predetermined amount of petroleum fuel into a storage tank for storing petroleum fuel for automobiles, the predetermined amount of petroleum fuel is charged. A step of pouring an injection agent composed of amine from above the storage tank into 0.25% by volume or more and less than 0.5% by volume, a step of pouring a predetermined amount of petroleum fuel from above the storage tank, and a step of pouring a predetermined amount of petroleum fuel into the storage tank. The fuel is allowed to stand for a predetermined time, and when the petroleum fuel falls from above in the storage tank, the injection agent existing below and the petroleum fuel collide with each other and are mixed, and a predetermined value is provided. It is characterized in that these are uniformly mixed by statically priced for a period of time.

According to this configuration, the petroleum fuel and the injection agent can be uniformly mixed, and the variation in the quality of the automobile fuel supplied to the automobile can be suppressed. By using the fuel for automobiles produced by this method for automobiles, the fuel consumption is reduced, the carbon dioxide generated is also reduced, and the fuel is stable for a long period of time.

Further, by pouring the injection agent and the petroleum fuel into the storage tank and keeping the price static for a predetermined time, the injection agent and the petroleum fuel are uniformly mixed due to the flow due to the ejection of the petroleum fuel and the convection due to the imbalance of density. In addition, the water surface in the storage tank is stable.

Further, by setting the injection agent to be mixed with the petroleum fuel to 0.25% by volume or more and less than 0.5% by volume, fuel efficiency is improved and carbon dioxide generated is reduced as compared with the conventional case.

In addition, the amine-based injection agent has the ability to adsorb to the metal surface to reduce friction and prevent rust, so it qualitatively improves lubrication performance, smoothes engine rotation, and prevents rust. Has acid neutralizing ability. Therefore, oxidative deterioration of engine oil is prevented. This effect is greater if the engine oil is oxidatively degraded.

In addition, since the injection agent has a cleaning effect, it has the effect of removing dirt such as rust in the engine. Therefore, the fuel for automobiles mixed with this injection agent removes the dirt in the engine and the engine moves. Contributes greatly to improving fuel efficiency and reducing carbon dioxide. Therefore, this fuel for automobiles is particularly effective in used automobiles.

Further, in this method for producing an automobile fuel, the content of the tertiary amine is 98% or more, the content of the secondary amine is 1% or less, and the content of the primary amine is 1% in the above-mentioned amine. It is as follows. Here, as an example, the components constituting this amine have a tertiary amine content of 98% or more and 99.8% or less, and a secondary amine content of 0.1% or more and 1% or less. The content of the primary amine is 0.1% or more and 1% or less.

Further, in the method for producing a fuel for automobiles, the tertiary amine is dimethylalkylamine.

Further, in the method for producing fuel for automobiles, the step of pouring the petroleum fuel is a step of injecting and pouring the petroleum fuel. This configuration facilitates mixing of petroleum fuel and injectables.

Further, the method for producing fuel for automobiles may further include a step of stirring the fuel in the storage tank after the step of pouring the petroleum fuel.

Further, in the method for producing fuel for automobiles, the petroleum fuel is light oil.

One aspect of the method for improving fuel efficiency of an automobile according to the present invention is characterized by comprising a step of refueling an automobile fuel tank with the automobile fuel produced by the above-mentioned method for producing an automobile fuel. According to this configuration, fuel efficiency is improved.

The automobile fuel according to one aspect of the present invention contains an injection agent composed of amine in an amount of 0.25% by volume or more and less than 0.5% by volume with respect to the petroleum fuel for automobiles. It is characterized in that the injection agent is uniformly mixed.

Further, in this automobile fuel, the amine has a tertiary amine content of 98% or more, a secondary amine content of 1% or less, and a primary amine content of 1% or less. .. Here, as an example, the components constituting this amine have a tertiary amine content of 98% or more and 99.8% or less, and a secondary amine content of 0.1% or more and 1% or less. The content of the primary amine is 0.1% or more and 1% or less.

Further, as the fuel for automobiles, the petroleum fuel is light oil.

Hereinafter, an embodiment according to the present invention will be described, but the present invention is not limited to the following embodiments. In particular, this embodiment is a case where light oil is used as a fuel for automobiles, but it may be applied to gasoline, heavy fuel oil A, and kerosene.

(Manufacturing process of fuel for automobiles)
The fuel for automobiles according to this embodiment is produced by the following steps. FIG. 1 is an explanatory diagram showing a method for producing an automobile fuel according to the present embodiment.

As shown in FIG. 1, first, an injection agent consisting of a 5 L amine aqueous solution contained in a can 12 is poured into a 2000 L storage tank 11 for storing light oil by opening the lid above the storage tank 11. It falls below the storage tank 11. As an example, the amine aqueous solution used in the present embodiment is an aqueous solution containing about 1% of primary amine and secondary amine and about 98% of tertiary amine, and has about 1% C10 alkyl group and about C12 alkyl group. It is an amine aqueous solution of 98% and about 1% of C14 alkyl group.

Next, 2000 L of light oil is poured from above the storage tank 11 from the tank lorry 13 while being injected using a pump. Then, the light oil falls from above in combination with the injection of the pump, and is mixed with the injection agent existing in the lower part of the storage tank 11.

However, as the storage tank 11 is filled with light oil, the water level rises, and the water surface approaches the inflow port above the storage tank 11, making it difficult to mix the light oil and the injection agent.

Therefore, after all 2000 L of light oil is poured into the storage tank 11, the lid above the storage tank 11 is closed and the mixture is allowed to stand for 24 hours. In this state, since the flow due to the ejection of the light oil and the convection due to the imbalance of the density and the like occur, the light oil and the injection agent are uniformly mixed in the storage tank 11 by allowing the mixture to stand for 24 hours. Further, since the water surface in the super image tank 11 is stable, it is easy to handle when refueling.

Prior to standing for 24 hours or while flowing light oil, the inside of the storage tank 11 may be stirred and mixed using a pump or the like (not shown). In this way, the light oil and the injection agent are mixed. Is promoted more.

(Vehicle fuel test)
Subsequently, each test was conducted on light oil to which an injection agent was added. The first test is a lubricity test when a predetermined amount of an injection agent is added to light oil, and the addition amount of the injection agent is 0%, 0.25%, 0.5%, 1%, 5%, 10%. , 20%. FIG. 2 is a graph showing the lubricity at each addition amount. From this result, it was found that adding more than 5% of the injectable agent to light oil had the opposite effect, and the lubricity was good at 1% or less, especially when 0.25% -0.5% was added. It turned out to be.

The second test is a test in which the peroxide value of the light oil to which 1% of the injection agent is added and the light oil to which no injection agent is added is measured. In addition, this test was carried out by an acceleration test, and these light oils were carried out for 78 weeks. 78 weeks is equivalent to 6 years in terms of room temperature.

FIG. 3 is a graph showing the peroxide value. From this result, the peroxide value of the additive-free light oil gradually increased from 13 weeks (equivalent to 1 year), and the peroxide value became very high from about 40 weeks, whereas the injectable was added. It can be seen that the peroxide value of light oil hardly changes. That is, it was found that light oil deteriorates due to oxidation, but deterioration can be prevented for a long period of time by adding an injection agent to the light oil.

The third test is a test in which the color change of the light oil to which 1% of the injection agent is added and the light oil to which no injection agent is added is measured. In addition, this test was carried out by an acceleration test, and these light oils were carried out for 78 weeks. 78 weeks is equivalent to 6 years in terms of room temperature. FIG. 4 is a graph showing a color change (Sabolt color).

As shown in Fig. 4, the color change of the additive-free light oil gradually decreased from 26 weeks (equivalent to 2 years), and the color changed to very low from about 40 weeks. It can be seen that the color of Sebolt hardly changes with the light oil to which the injection agent is added. That is, it was found that the change in the color of the light oil can be prevented from deteriorating for a long period of time by adding the injection agent to the light oil.

The fourth test is a test for changes in rust on the surface of a can by injecting a light oil to which 1% of an injection agent is added and a light oil to which no injection agent is added into a rusted can. As can be seen from the results of FIG. 5, the rust on the can surface is not changed even when the light oil without the injection agent is sprayed, but the rust on the can surface is removed with the light oil with the injection agent added. You can see that. From this result, it is expected that the rust in the internal combustion engine will be removed by using the light oil to which the injection agent is added, which makes the internal combustion engine move smoothly and leads to the improvement of fuel efficiency.

Next, as a fifth test, light oil to which an injectant was added was put into an automobile engine, the engine was operated, and a test was conducted for exhaust gas components emitted. Specifically, as shown in FIG. 6, the exhaust gas is taken into the exhaust gas measuring device 5 by the heat-resistant hose 4 from the exhaust pipe 2 of the engine 1 via the hot filter 3, and the rate of increase / decrease in the CO2 concentration in the exhaust gas. Was measured.

In this test, the test was carried out a plurality of times with light oil to which no injection agent was added and light oil to which 0.25%, 0.5% and 1% were added at different engine speeds. Reference numeral 6 is an input device for setting test conditions and the like, and reference numeral 7 is an output device (for example, a pen recorder) for outputting test results. From the results shown in FIGS. 7 to 9, it can be confirmed that the addition of the injecting agent reduces CO2 as compared with the case of no addition. It can also be seen that 0.25% of the injectable is the best, followed by 0.5%.

(Road driving test)
Next, as a sixth test, a running test was conducted on the light oil to which the injection agent was not added and the light oil to which the injection agent was added. This driving test was conducted on an actual public road using a large number of vehicles and a huge amount of time, instead of the conventional fuel consumption measurement method such as 10/15 mode driving and JC08 mode driving, which had a difference from the actual fuel consumption. Is.

First, the fuel consumption and the mileage when driving on an actual public road with a car refueled with light oil to which no injection agent was added were measured for about one year, and this was used as a reference (see FIG. 10). Then, each fuel consumption and mileage when driving on an actual public road with a car refueled with light oil added by changing the amount of injection agent added is measured for several months to one year, and the additive-free light oil is used as a reference. We compared the improvement of fuel efficiency. In this running test, a lubricating oil to which 0.3% -0.5% of this injection agent was added was used as appropriate.

The results of this running test are shown in FIGS. 10 to 15. As shown by these, it can be seen that the fuel consumption when the light oil to which the injection agent is added is refueled is improved from 3.4% to 9.8% as compared with the case of the light oil without the addition. In particular, it can be seen that the fuel efficiency is significantly improved when 0.25% is added as compared with the case where 0.5% or 1% is added.

From these first to sixth test results, it is found that when the injectable agent is added to light oil in the range of 0.25% or more and less than 0.5, fuel efficiency is improved and carbon dioxide reduction is effective. I can say. Regarding the effect of improving fuel efficiency and reducing carbon dioxide, the company represented by the inventor of the present application has obtained EQA's carbon management system certification (see FIGS. 16 and 17).
