20130228144
The present invention relates to lubrication oil. In particular, the present invention relates to internal-combustion engine lubrication oil and internal-combustion engine fuel.
Generally, it has been known that the global warming is influenced by the carbon dioxide caused by the combustion of petroleum oil fuel used in an internal-combustion engine.
In the current economic situation, exchanging or improving various pieces of equipment such as a vehicle, a heavy machine, or a boiler is difficult but the reduction of carbon dioxide has been strongly required.
In a machine such as an internal-combustion engine or a driving system, lubrication oil is used in order to reduce the friction caused during the operation of a gear or a piston. When lubrication oil is used in an internal-combustion engine or a driving system, the friction can be reduced to provide a smooth rotation of a gear or a piston for example, thus reducing the consumption amount of fuel (e.g., light oil, gasoline) and the emission amounts of carbon dioxide and other exhaust gas components caused in the combustion.
On the other hand, lubrication oil is oxidized and deteriorated when subjected to the use for a long period of time. The oxidized lubrication oil causes acid substance, varnish, or sludge for example, thus promoting deterioration such as an increased acid number or an increased viscosity. There are various disadvantages where such an acid substance for example causes the worn parts of an internal-combustion engine or the wear or lubrication oil having an increased viscosity causes an increased power loss, which hinders the operation of the internal-combustion engine.
The mechanical parts of the internal-combustion engine rust due to various causing factors such as water ingression by rain and wind for example. The rust causes an increased power loss, thus hindering the operation of the internal-combustion engine.
By the way, lubrication oil is added with (a) copolymer having a number average molecular weight in the range higher than 6300 and lower than 1200 of octadecene 1 and maleic anhydride and (b) dispersant/VI improver additive agent including a succinimide reaction product prepared from polyamine and acyclic hydrocarbyl-substituted succinic acylating agents. As a result, resolving agent disperses the varnish and sludge components in the entire oil to thereby prevent the accumulation thereof, according to the disclosed invention (see Patent Publication 1 for example).
Regarding petroleum oil fuel itself, it has been previously suggested to add, in a diesel engine, fuel additive substance to the petroleum oil fuel to provide a favorable combustion efficiency to thereby improve the fuel consumption (see Patent Publication 2 for example).
However, the invention according to Patent Publication 1 uses the resolving agent to disperse sludge for example to suppress the oxidation and deterioration of lubrication oil. However, the dispersibility cannot be maintained for a long time, the suppression of the oxidation and deterioration of the lubrication oil is not so high, and the effect of reducing carbon dioxide is insufficient. Furthermore, the rust prevention effect for mechanical parts is not achieved.
In the case of the technique as disclosed in Patent Publication 2 to include additive substance in petroleum oil fuel, to attach a fuel reduction apparatus, or to attach an exhaust gas reduction apparatus, carbon dioxide cannot be reduced. The complete combustion causes increased carbon dioxide and a fine-tuned engine causes increased carbon dioxide.
On the other hand, the inventor has carried out the eco-drive education for saving fuel consumption for over ten years. However, the fuel consumption can be saved by about 1% to 2% only. Even when a digital tachograph is attached to manage the driver, there is no remarkable difference in fuel consumption between a vehicle attached with the digital tachograph and a vehicle driven by a highly-experienced driver performing eco-driving.
In view of the above, the inventor has been researching how to reduce the carbon dioxide generation by using internal-combustion engine lubrication oil for a long time. Finally, the inventor has found an effect that eco-substance (dimethylalkyl tertiary amine) injected to lubrication oil can reduce the friction among the parts of the internal-combustion engine, prevent the oxidation and deterioration of the lubrication oil, and can reduce the wear to provide a longer life to various engines.
The inventor also found that various engines can have a rust prevention effect, thus contributing to various engines having a longer life. Thus, the inventor was convinced that the reduction of carbon dioxide and the reduction of exhaust gas components (CO, HC, NOx gas) and the fuel consumption can be achieved, thus reaching the present invention.
The inventor also found that, through a keen research for realizing internal-combustion engine fuel causing less carbon dioxide, eco-substance (dimethylalkyl tertiary amine) injected to petroleum oil fuel can effectively reduce carbon dioxide, other exhaust gas components, and fuel consumption.
In other words, the fuel consumption in light oil, kerosene, gasoline, and Bunker A can be reduced, the amount of carbon dioxide in the exhaust gas can be reduced, and CO, HC, and NOx gas also can be reduced.
It is an objective of this invention to provide internal-combustion engine lubrication oil that has reduced deterioration, a friction reduction effect, and a rust prevention effect as well as internal-combustion engine fuel that can reduce carbon dioxide, a fuel consumption amount, and all exhaust gas.
In order to solve the above disadvantage, lubrication oil according to the present invention is injected with impregnating agent composed of dimethylalkyl tertiary amine in the range from 0.01 to 1 volume %. The dimethylalkyl tertiary amine may be, for example, dimethyllaurylamin, dimethylmyristylamine, or dimethylcocoamine for example.
According to this configuration, the impregnating agent (dimethylalkyl tertiary amine) is adsorbed to the metal surfaces of the respective parts of the internal-combustion engine or the driving system for example to reduce friction. Thus, rotating parts such as a gear or a bearing for example can have a reduced friction resistance, thus providing a smooth operation. Thus, an internal-combustion engine for example using this lubrication oil can have a reduced amount of fuel consumption and reduced carbon dioxide and other exhaust gas components (e.g., CO, HC, NOx, SOx, PM). The internal-combustion engine for example using this lubrication oil also can have suppressed wear of the gear or bearing for example, thus providing a longer life of various engines. Furthermore, since the lubrication oil impregnating agent can provide rust prevention acid neutralization, the oxidation and deterioration of the lubrication oil can be suppressed. Thus, the above-described fuel reduction effect or the effect of reducing carbon dioxide for example can be realized for a long time.
The lubrication oil according to claim 2 may have the dimethylalkyl tertiary amine represented by the general expression (1).
(R represents an alkyl group.)
In the lubrication oil according to claim 3, the dimethylalkyl tertiary amine is desirably formed by oils of plants and animals for environmental friendliness.
In the lubrication oil according to claim 4, the impregnating agent is preferably injected in an amount of 0.1 to 0.5 volume % from the viewpoints of performance and cost.
In the lubrication oil according to claim 5, the lubrication oil may be internal-combustion engine lubrication oil. The internal-combustion engine lubrication oil means engine oil for example. By using lubrication oil as engine oil, a reduced load can be applied to an engine, a main shaft, a clutch, a mission, a propeller shaft, a joint bearing, a differential gear, a rear shaft, a wheel bearing, a battery, or a starter for example. Thus, the respective parts can have reduced friction and can have remarkably-reduced fuel consumption, thus achieving the corresponding reduction of carbon dioxide and other types of exhaust gas. The lubrication oil also may be used, in addition to engine oil, for power steering oil, turbine oil, or gear oil for example.
The lubrication oil according to claim 6 may be used in internal-combustion engine together with internal-combustion engine fuel injected with the lubrication oil impregnating agent in the range from 0.1 to 1 volume %. According to this configuration, the internal-combustion engine fuel (e.g., gasoline) injected with the impregnating agent can provide, when being used together with the lubrication oil of the present invention, not only the effect by the lubrication oil but also a reduced fuel consumption by the internal-combustion engine fuel mixed with the impregnating agent, thus additionally achieving the effect of reducing carbon dioxide and other exhaust gas components. Even at a part to which the lubrication oil cannot reach (e.g., a top part of a con rod), an oil film is formed by jetted internal-combustion engine fuel. This oil film provides the same function as that of the lubrication oil to provide a smooth operation of various engines (see
In the lubrication oil according to claim 7, impregnating agent composed of dimethylalkyl tertiary amine is injected in the range from 1 to 5 volume % and thickener is injected so that the resultant oil is jellylike. The jellylike lubrication oil means the one such as grease that is used by being coated on a bearing or a shaft for example. The thickener is injected in order to cause the lubrication oil to be semisolid and may be, for example, calcium, sodium, lithium, or aluminum for example. According to this configuration, the respective parts can have reduced friction thereamong, smooth operation can be obtained, reduced fuel consumption can be achieved, and the reduction of carbon dioxide and other exhaust gas components can be reduced. A rust prevention effect also can be obtained, thus providing a longer life to the machine. While the lubrication oil of claims 1 to 6 is mainly used in an internal-combustion engine (e.g., engine oil), the jellylike lubrication oil is mainly used for a bearing or a tire shaft for example. Thus, the impregnating agent can be used in a relatively-high amount.
In the invention according to claim 8, petroleum oil fuel is injected with fuel oil impregnating agent composed of dimethylalkyl tertiary amine in the range from 0.5 to 1 volume %. The dimethylalkyl tertiary amine may be amine DM12D, amine DM14D, or amine DM16D (product names used by LION AKZO Co., Ltd.).
According to the invention of claim 8, when the fuel is used in an internal-combustion engine, a fuel consumption amount is reduced, carbon dioxide and other exhaust gas components are reduced, and stability is achieved for a long period.
When the fuel of claim 8 is used as vehicle fuel, the engine noise is improved at the speed of about 20 km and the exhaust gas temperature of 70 to 100 degrees C., showing a highly-efficient combustion. Since the fuel combusts at a low temperature, CO2 is absorbed and the combustion reaction is promoted.
In addition, the fuel oil impregnating agent (dimethylalkyl tertiary amine) can be adsorbed to a metal surface to provide friction reduction and rust prevention. Thus, the lubrication performance is improved qualitatively, a smooth engine rotation is provided, and the rust prevention acid neutralization is realized, thus preventing the oxidation and deterioration of engine oil. This effect is significant when the engine oil is oxidized and deteriorated.
Furthermore, air pollutant such as sulfur oxide (SOx), black smoke, or particulate matter (PM) is reduced and CO, HC, or NOx is also reduced.
As described in claim 9, the petroleum oil fuel composed of light oil, kerosene, gasoline, or Bunker A is effectively used.
As described in claim 10, from the viewpoint of cost in particular, the fuel oil impregnating agent is desirably injected in an amount of 0.99 to 1 volume %.
As described above, according to the present invention, lubrication oil is injected with impregnating agent composed of dimethylalkyl tertiary amine in the range of 0.01 to 1 volume %. Thus, when the lubrication oil is used in an internal-combustion engine such as an automobile engine, various engines can have reduced friction resistance, the fuel consumption amount is reduced, and the carbon dioxide and other exhaust gas components are also reduced. The lubrication oil also provides a rust prevention effect, suppresses the oxidation and deterioration of the lubrication oil, suppresses the wear of the respective parts, and can provide the internal-combustion engine with a longer life.
Petroleum oil fuel injected with fuel oil impregnating agent composed of dimethylalkyl tertiary amine in the range from 0.5 to 1 volume % allows, when the petroleum oil fuel is used in an internal-combustion engine such as an automobile engine, the fuel consumption amount to be stably reduced for a long period and also allows carbon dioxide and other exhaust gas components to be reduced.
The following section will describe an embodiment of the present invention with reference to the drawings and tables. The lubrication oil according to the present invention is obtained by injecting lubrication oil impregnating agent composed of dimethylalkyl tertiary amine (hereinafter referred to as eco-substance) to conventional lubrication oil. The eco-substance is injected in the range from 0.01 to 1 volume % and desirably in the range from 0.1 to 0.5 volume %. The reason is that the injection amount lower than 0.1 volume % prevents a sufficient effect from being provided and that the lubrication oil used in a machine such as an internal-combustion engine with the injection amount exceeding 0.5 volume % causes an insufficient effect not enough for a high price. It is confirmed that the lubrication oil injected with the impregnating agent within the above range can be used as general lubrication oil, according to a component analysis.
It is also confirmed that the lubrication oil injected with the eco-substance can provide a desired effect as described later.
The eco-substance may be, for example, dimethyllaurylamine, dimethylmyristylamine, dimethylcocoamine, dimethylpalmitinamine, dimethylbehenylamine, dimethylcocoamine, dimethyl palm stearin amine, or dimethyldesineamine. These eco-substances have different melting points, respectively, and are selectively used based on the application or the point of use of the lubrication oil for example. In this embodiment, the eco-substance is dimethyllaurylamine.
First, lubrication oil is injected with the eco-substance (dimethyllaurylamine) at 0.1 volume %, 0.3 volume %, and 0.5 volume % to thereby manufacture the new eco-friendly lubrication oil having the respective concentrations. The new eco-friendly lubrication oil including the eco-substance at the respective concentrations (volume %) is manufactured, for example, by injecting into a tank including lubrication oil of 100 liters the eco-substance of 0.1 liter for the concentration of 0.1 volume %, the eco-substance of 0.3 liter for the concentration of 0.3 volume %, and the eco-substance of 0.5 liter for the concentration of 0.5 volume % to stir and mix the lubrication oil with the eco-substance.
Next, the manufactured new eco-friendly lubrication oil was used to perform a running test and a black smoke test. These tests were performed in order to compare conventional lubrication oil with the new eco-friendly lubrication oil. In these tests, the lubrication oil was engine oil and the new eco-friendly lubrication oil was conventional engine oil injected with the above predetermined eco-substance.
The vehicles (automobiles) used in the running test were: a diesel truck (a 4t vehicle, a 10t vehicle (gross weight of 20t), and a tractor (gross weight of 40t) for example), a diesel passenger vehicle (“SAFARI” (registered trademark)), a regular gasoline passenger vehicle (“BMW” (registered trademark) of 1600 cc), and a high-octane gasoline passenger vehicle (“MERCEDES-BENZ” (registered trademark) of 6000 cc). In these vehicles, light oil was used in the diesel truck and passenger vehicle and regular gasoline or high-octane gasoline was used in the gasoline vehicles. In order to provide uniform running conditions (e.g., a running speed, a running distance) as much as possible, the respective vehicles were driven by the same driver to run on the same route. In order to prevent an error, the consumption fuel was measured correctly and the running distance was measured correctly by a running distance meter. Then, the resultant fuel consumptions were compared.
(1) New Eco-Friendly Lubrication Oil Including 0.1 Volume % of Eco-Substance
Table 1 to Table 5 show the result of the running tests using the new eco-friendly lubrication oil including 0.1 volume % of the eco-substance. Table 1 and Table 2 are tables showing the result of the running test for the comparison in the fuel consumption for the respective diesel trucks using light oil as fuel between a case where the conventional engine oil was used and a case where the new eco-friendly lubrication oil was used. The tables show, from the left side, the vehicle information, the destination, the stopover point, the running distance, and the consumption fuel for example when the conventional engine oil (normal lubrication oil) was used, and the destination, the stopover point, the running distance, and the consumption fuel for example when the new eco-friendly lubrication oil was used. The rightmost section shows how much fuel consumption was reduced and how much average fuel consumption was reduced for the respective vehicles by the use of the new eco-friendly lubrication oil from the fuel consumption amount of the normal lubrication oil. The lowermost section shows how much average fuel consumption was reduced for all of the vehicles.
As can be seen from these results, the fuel consumption performance is improved by the use of new eco-friendly lubrication oil when compared with a case where the normal lubrication oil is used. The improved fuel consumption provides the reduction of emitted carbon dioxide and other exhaust gas components.
Table 3 and Table 4 are tables showing, with regard to the respective vehicles using gasoline (regular or high-octane) as fuel, the result of the running test for the comparison of the fuel consumption between a case where the conventional engine oil was used and a case where the new eco-friendly lubrication oil was used. These tables show the destinations of the respective routes, the stopover points, the respective distances, the total running distances, the fuel consumption amounts, the fuel consumption, and how much fuel consumption was reduced by the use of the new eco-friendly lubrication oil from the fuel consumption amount of the normal lubrication oil. The lowermost section shows how much average fuel consumption was reduced for all of the routes. In the table, the term “new eco-friendly oil” means the new eco-friendly lubrication oil.
As can be seen from these results, the fuel consumption performance is improved, also in the gasoline vehicle, by the use of new eco-friendly lubrication oil when compared with a case where the normal lubrication oil is used.
From the above description, it is understood that the fuel consumption performance is improved, both in the diesel trucks and the gasoline vehicles, by the use of new eco-friendly lubrication oil including 0.1 volume % of the eco-substance.
Table 5 shows the comments by the driver regarding the change from the normal lubrication oil to the new eco-friendly lubrication oil. The comments at least did not include any answer showing bad fuel consumption or vehicle.
(2) New Eco-Friendly Lubrication Oil Including 0.3 Volume % of Eco-Substance
Table 6 to Table 12 show the result of the running tests using the eco-friendly lubrication oil including 0.3 volume % of the eco-substance. Table 6 and Table 7 show, as in Table 1 and Table 2, the result of the running test for the comparison in the fuel consumption for the respective diesel trucks (10t vehicles) using light oil as fuel between a case where the conventional engine oil was used and a case where the new eco-friendly lubrication oil was used. Table 8 shows the data for the running test regarding the diesel truck (10t vehicle) having the vehicle number 353. The 353 vehicle was caused to run on generally the same route for many times.

As can be seen from these results, the fuel consumption performance is improved, in the diesel trucks using light oil, by the use of new eco-friendly lubrication oil including 0.3 volume % of eco-substance when compared with a case where the normal lubrication oil is used.
Table 9 shows the test result when the new eco-friendly lubrication oil including 0.3 volume % of the eco-substance was used in the diesel trucks (4t vehicle) using light oil as fuel. Table 10 shows the test result for the diesel passenger vehicle using light oil as fuel.
As can be seen from these results, the fuel consumption performance is improved, also in the diesel truck (4t vehicle) and the diesel passenger vehicle using light oil, by the use of the new eco-friendly lubrication oil including 0.3 volume % of the eco-substance when compared with a case where the normal lubrication oil is used.
Table 11 and Table 12 show, as in Table 3 and Table 4, the result of the running test for the comparison in the fuel consumption for the respective vehicles using gasoline (regular and high-octane) as fuel between a case where the conventional engine oil was used and a case where the new eco-friendly lubrication oil was used.
As can be seen from these results, the fuel consumption performance is improved, also in the gasoline vehicles, by the use of the new eco-friendly lubrication oil including 0.3 volume % of the eco-substance when compared with a case where the normal lubrication oil is used.
As can be seen from the above, the fuel consumption performance is improved, also in any of the diesel truck and the passenger vehicle using light oil as fuel and the gasoline vehicle, by the use of the new eco-friendly lubrication oil including 0.3 volume % of the eco-substance.
(3) New Eco-Friendly Lubrication Oil Including 0.5 Volume % of Eco-Substance
Table 13 to Table 15 show the result of the running tests using the eco-friendly lubrication oil including 0.5 volume % of the eco-substance regarding the gasoline vehicle using high-octane gasoline, the gasoline vehicle using regular gasoline, and the diesel passenger vehicle using light oil as fuel. Table 13 shows the test result for high-octane gasoline. Table 14 shows the test result for regular gasoline. Table 15 shows the test result for light oil as fuel.
As can be seen from these results, the fuel consumption performance is improved, at least in the passenger vehicle using gasoline and light oil as fuel, by the use of new eco-friendly lubrication oil including 0.5 volume % of eco-substance when compared with a case where the normal lubrication oil is used.
The respective vehicles were black smoke test in order to compare the new eco-friendly lubrication oil including 0.3 volume % of the eco-substance with the normal lubrication oil regarding the black smoke concentration.
In the black smoke test, a probe (a exhaust gas extraction sheet of a black smoke measuring instrument) was inserted to an exhaust pipe by about 20 cm to allow the exhaust gas to pass through the probe. Then, the probe on which impurities were attached was placed in the black smoke measuring instrument to measure the black smoke concentration. The blacker the probe is, the more impurities are attached thereto, thus resulting in a higher black smoke concentration.
(i) In the black smoke test, the vehicle was stopped and the change gear was at a neutral position.
(ii) A motor was operated under no load. Then, an accelerator pedal was pushed down rapidly until the highest rotation number was reached. Then, the accelerator pedal was released until the no-load running is reached. The above operation was repeated 2 or 3 times.
(iii) Next, the no-load running was performed for about 5 seconds and the accelerator pedal was pushed down rapidly to retain this state for about 4 seconds. Thereafter, the accelerator pedal was released and this state was retained for about 11 seconds. The above operation was repeated 2 or 3 times
(iv) The extraction of black smoke was started when the accelerator pedal was pushed down in (iii). The probe was purged (to scavenge any remaining black smoke) just before the extraction of black smoke.
(v) The above steps of (i) to (iv) were repeated 3 times. Then, the resultant average value was determined as a black smoke concentration.
Table 16 shows the list of the results of the black smoke test for the respective vehicles. The left side shows the result for the normal lubrication oil. The right side shows the result for the new eco-friendly lubrication oil including 0.3 volume % of the eco-substance.
As can be seen from the above, the use of the new eco-friendly lubrication oil including 0.3 volume % of the eco-substance can reduce black smoke, thus improving the performance. Furthermore, less emitted black smoke also achieves environmental friendliness.
Table 17 to Table 19 show the comments by the drivers of the respective vehicles regarding the behavior and horsepower of the engine, the fuel consumption, and exhaust gas smoke for example.
As can be seen from these comments, according to the comments by the drivers, the use of the new eco-friendly lubrication oil provides, when compared with the use of the conventional lubrication oil, at least equal or improved engine behavior, fuel consumption, and exhaust gas smoke amount.
Next, the following section will describe an embodiment of the internal-combustion engine fuel injected with eco-substance with reference to the drawings.
The internal-combustion engine fuel according to the present invention is obtained by injecting (or adding) fuel oil impregnating agent composed of dimethylalkyl tertiary amine (hereinafter referred to as eco-substance) to petroleum oil fuel. The eco-substance is injected in the range from 0.5 to 1 volume % and desirably in the range from 0.99 to 1 volume %. The reason is that the injection amount lower than 0.5 volume % prevents a sufficient effect from being provided and that the injection amount exceeding 1 volume % causes an insufficient effect not enough for a high price. It is confirmed that light oil, kerosene, gasoline, or Bunker A injected with the fuel oil impregnating agent within the above range is handled as light oil, kerosene, gasoline, or Bunker A, according to a component analysis.
The petroleum oil fuel is light oil, kerosene, gasoline, or Bunker A and can provide, by being injected with the eco-substance, a desired effect as described later.
The eco-substance may be amine DM12D, amine DM14D, or amine DM16D (product name used by LION AKZO Co., Ltd.).
Next, as shown in
In this test, as shown in
In Table 20 to Table 36, DLMA is the amine DM12D and DMMA is the amine DM16D.
As can be seen from the result shown in the above tables, the light oil, kerosene, gasoline, or Bunker A injected with the eco-substance can reduce CO2 when compared with fuel not injected with the eco-substance. The light oil, kerosene, gasoline, or Bunker A injected with the eco-substance also can reduce sulfur oxide (SOx), black smoke, and particulate matter (PM) as an air pollutant and can reduce CO, HC, and NOx.
Then,
The result was that any of the high-octane gasoline, regular gasoline, kerosene, and clean Bunker A showed a reduced consumption fuel, resulting in the reduction rate of 5% to 21%. In particular, gasoline showed a reduction rate of 9.5% to 21% and kerosene and Bunker A showed a reduction rate of 5% to 9%. This shows that a significant reduction effect is obtained when the fuel is gasoline.
As in the high-octane gasoline, regular gasoline, kerosene, and clean Bunker A, light oil injected with the eco-substance shows a reduced consumption fuel, thus improving the fuel consumption.
Table 37 to Table 54 show the result of the test to further confirm the fuel consumption.
As can be seen from Table 37, all of the vehicles show an average reduction rate of −6.4% and the 10t vehicle shows an average reduction rate of −7.1%.
Table 38 shows that an average reduction rate of −5% is achieved in 8 running tests for which the loading place is Kobe-shi of Hyogo ken and the unloading place is Iizuka-shi of Fukuoka ken.
Table 39 to Table 41 show that an average reduction rate of −12% is achieved in 4 running tests for the outward path (loading place: Amagasaki-shi of Hyogo ken, unloading place: Kawaguchi-shi of Saitama ken) and the return path (loading place: Ueda-shi of Nagano ken, unloading place: Amagasaki-shi of Hyogo ken).
Table 42 and Table 43 show that an average reduction rate of −13% is achieved in 5 running tests for which the loading place is Wajima of Ishikawa ken and the unloading place is Amagasaki-shi of Hyogo ken.
Table 44 to Table 46 show that an average reduction rate of −12% is achieved in 9 running tests for which the loading place is Nakaniikawa-gun of Toyama ken and the unloading place is Takasago-shi of Hyogo ken.
Table 47 and Table 48 show that an average reduction rate of −14% is achieved in 3 running tests for which the loading place is Noto of Isikawa ken and the unloading place is Amagasaki-shi of Hyogo ken.
Table 49 and Table 50 show that an average reduction rate of −9% is achieved in 3 running tests for the outward path (loading place: Amagasaki-shi of Hyogo ken, unloading place: Kitatone of Ibaragi ken) and the return path (loading place: Sano-shi of Tochigi ken, unloading place: Amagasaki-shi of Hyogo ken).
Table 51 and Table 52 show that an average reduction rate of −8% is achieved in 5 running tests for the outward path (loading place: Izumisano-shi of Osaka-fu, unloading place: Echizen-shi of Fukui ken) and the return path (loading place: Nakaniikawa-gun of Toyama ken, unloading place: Takasago-shi of Hyogo ken).
Table 53 and Table 54 show that an average reduction rate of −6% is achieved in 11 running tests for which the loading place is Amagasaki-shi of Hyogo ken and unloading place is Noto of Isikawa ken.
Table 55 to Table 57 show that an average reduction rate of −17% is achieved in 9 running tests for which the loading place is Yokkaichi-shi of Aichi ken and unloading place is Amagasaki-shi of Hyogo ken.
As is clear from these results, the fuel consumption performance can be improved. The fuel consumption performance is improved when the injection amount of the eco-substance is about 0.5 volume %.
4. [Running Test when the Eco-Fuel is Used in Combination]
Next, the running test was performed for a case where the eco fuel obtained by injecting the eco-substance to the internal-combustion engine fuel (light oil, gasoline for example) was used with the new eco-friendly lubrication oil, the result of which is shown in Table 58 to Table 60. In Table 58 and Table 59, with regard to a diesel truck using light oil, the left side shows the result when the normal fuel and the normal lubrication oil were used, the middle side shows the result when the eco fuel and the normal lubrication oil were used, and the right side shows the result when the eco fuel and the new eco-friendly lubrication oil were used. Table 60 shows the result for a passenger vehicle using regular gasoline.

As can be seen from the above, the combination of the eco
fuel and the new eco-friendly lubrication oil can further improve the fuel consumption performance.
The reason why the combination of the eco fuel and the new eco-friendly lubrication oil can improve the fuel consumption performance is that the eco fuel injected with the eco-substance itself has an effect of reducing the fuel consumption and also functions like lubrication oil partially in the mechanical parts. Thus, the eco-substance included in the fuel provides the effect.
Specifically, in the piston 2 and the con rod 1 shown in
On the other hand, the non-existence of an oil film at the upper side than the concave section 3d of the piston 2 undesirably causes metal attack. However, in an actual case, the fuel injected from the upper side of the piston 2 forms a thin oil film (arrow B) to suppress the metal attack at the upper side of the piston 2, thus allowing the fuel to function like lubrication oil.
When the fuel includes the eco-substance at this stage, friction is reduced compared with the conventional case and the oxidation and deterioration of the fuel as lubrication oil can be suppressed. It is also effective to prevent the rust of the piston 2.
Next, a rust prevention experiment was performed to investigate the rust prevention effect of the new eco-friendly lubrication oil. The rust prevention experiment was performed in the manner as described below. Specifically, the respective parts coated with normal lubrication oil and the respective parts coated with the new eco-friendly lubrication oil were left outside. Then, the rust states of the respective parts after the passage of a predetermined period were visually inspected.
The parts coated with the normal lubrication oil were significantly oxidized and showed a high amount of red rust. On the other hand, the parts coated with the new eco-friendly lubrication oil showed a very small amount of red rust. This clearly shows that the new eco-friendly lubrication oil has a rust prevention effect
As described above, the new eco-friendly lubrication oil injected with the eco-substance can reduce, when being used in an internal-combustion engine such as an automobile engine, the friction resistance in various engines, can reduce the fuel consumption amount, and can reduce carbon dioxide and other exhaust gas component. The new eco-friendly lubrication oil injected with the eco-substance also provides a rust prevention effect, suppresses the oxidation and deterioration of lubrication oil, suppresses the wear of the respective parts, thus providing a longer life to the internal-combustion engine.
The lubrication oil used for a grease application is manufactured by injecting the eco-substance (dimethyllaurylamine) of 1 to 5 volume % to conventional lubrication oil to subsequently inject thickener (e.g., calcium, sodium, lithium, aluminum, fatty acid salt) to uniformly disperse the thickener to thereby obtain a jellylike form. Then, the resultant jellylike lubrication oil can be used for a thrust bearing, an intermediate bearing, or a tire shaft for example to thereby reduce the friction resistance, to reduce the fuel consumption amount, and to reduce carbon dioxide and other exhaust gas components. Since this lubrication oil also has a rust prevention effect, this lubrication oil can suppress the oxidation and deterioration of the respective parts, thus providing a longer life to various engines. The jellylike lubrication oil also can be used not only for the above applications but also for respective parts of other various machines or equipment for example.
As described above, an embodiment of the present invention has been described with reference to the drawings and tables. However, various additions, changes, or deletions are possible within the scope not deviating from the intention of the present invention. In particular, the eco-substance is not limited to dimethyllaurylamine and also may be other dimethylalkyl tertiary amine. The eco-substance can be used as engine oil in an internal-combustion engine and also can be used as power steering oil, turbine oil, or gear oil and also can be used as lubrication oil for a driving system. Thus, such modifications are also included in the scope of the present invention.
