Definitions
- the present invention relates to a diesel fuel additive composition added to diesel fuel, and a scouring method using the same.
- a means to solve this problem is a diesel engine equipped with a common-rail-type fuel injection system.
- a common-rail-type fuel injection system accumulates the fuel pressurized by a fuel injection pump, in a common-rail, which is an accumulator container, and blows the high-pressure fuel accumulated in the common-rail into a cylinder through a fuel injector nozzle.
- the common-rail-type fuel injection system has the problem that the fuel is exposed to high temperature and high pressure and consequently various additives in the fuel are denatured, and therefore, deposits adhere to the injector nozzle.

Description
- The present invention relates to a diesel fuel additive composition added to diesel fuel, and a scouring method using the same.
- Recently, from the viewpoint of environmental issues, reduction in the amount of nitrogen oxides (NOx), particulate matter (PM), etc. has become a problem. A means to solve this problem is a diesel engine equipped with a common-rail-type fuel injection system.
- A common-rail-type fuel injection system accumulates the fuel pressurized by a fuel injection pump, in a common-rail, which is an accumulator container, and blows the high-pressure fuel accumulated in the common-rail into a cylinder through a fuel injector nozzle.
- The common-rail-type fuel injection system has the problem that the fuel is exposed to high temperature and high pressure and consequently various additives in the fuel are denatured, and therefore, deposits adhere to the injector nozzle.
- In order to use the above injector nozzle adequately, it is necessary to remove the deposits.
- Thus far, various detergents to remove deposits have been reported (see Japanese unexamined patent publications No.
2008-81626 2008-81627 - Specifically, there are detergents comprising polybutene amine, polyether amine, etc., as a main component, which are effective in removing carbon-based deposits.
- Japanese unexamined patent publication No.
2008-81626 - Japanese unexamined patent publication No.
2008-81627 - However, in addition to the above-mentioned water-soluble deposits and water-insoluble deposits, polymer-substance derived deposits, which are derived from polymer type substances, such as an ethylene-vinyl acetate copolymer, contained in diesel fuel as a low-temperature fluidity improving agent may be mixed in the above deposits.
- In such a case, the detergent compositions described in Japanese unexamined patent publication No.
2008-81626 2008-81627 - If various solvents are used to scour the polymer-substance derived deposits, separation and swelling of the deposits occur, and therefore a portion of the fuel piping may become clogged with the separated and swelled deposits, thus resulting in engine stall.
- In view of the drawbacks of these prior arts, it is an object of the present invention to provide a diesel fuel additive composition that can be stably dispersed in diesel fuel, can remove polymer-substance derived deposits, water-soluble deposits, and water-insoluble deposits at once, and does not cause any adverse effect on an object to be scoured, and a scouring method using the diesel fuel additive composition.

- (b) glycol monoalkyl ether represented by Formula (2) below,

- (d) a heterocyclic compound, and
- (e) water;
- The diesel fuel additive composition of the present invention is added to diesel fuel to scour deposits adhering on an injector nozzle of a diesel engine equipped with a common-rail-type fuel injector.
- The above diesel fuel additive composition is stably dispersed in the diesel fuel due to the presence of the above components (a) to (e) at specific ratios, and therefore it is possible to remove polymer-substance derived deposits, water-soluble deposits, and water-insoluble deposits at once, without having any adverse influence on the to-be-scoured object.
- Stability of the above diesel fuel additive composition in the diesel fuel can be ensured by above component (a), polyoxyalkylene alkyl amine. Thus, the above diesel fuel additive composition can be dispersed stably, when it is added to diesel fuel.
- Polymer-substance derived deposits and water-insoluble deposits can be satisfactorily removed due to the presence of the above component (a), polyoxyalkylene alkyl amine, above component (b), glycol monoalkyl ether, above component (c), glycol dialkyl ether, and above component (d), a heterocyclic compound, altogether in the diesel fuel additive composition.
- Water-soluble deposits can be scoured due to the presence of above component (e), water.
- Water tends to corrode the to-be-scoured object, but it is possible to stably disperse the water and to prevent the corrosion of the to-be-scoured object by restricting the amount of above component (e) to be contained and also containing above component (a).
- Thus, the present invention can provide a diesel fuel additive composition that is stably dispersed in diesel fuel, can remove polymer-substance derived deposits, water-soluble deposits, and water-insoluble deposits at once, and does not cause any adverse effect on the object to be scoured.

On the other hand, if the content of the above fuel additive is more than 2% by weight, the water content in the fuel increases, so that an adverse effect may be exerted on the system using the above object to be scoured, for example, leading to corrosion of the object to be scoured.
- More preferably, the content of the above diesel fuel additive composition to diesel fuel is 1% by weight.
- The above fuel additive can be added to diesel fuel by pouring it into a fuel tank of a diesel engine, or diesel fuel blended with the diesel fuel additive composition beforehand may be used.
- To the diesel fuel additive composition of the present invention may be added other components (for example, a cetane number-improving agent such as octyl nitrate and cyclohexyl nitrate, a cleaning agent such as polyether amine and polybutenyl amine, a corrosion inhibitor such as aliphatic amine and alkenyl succinate ester, or an anti-freezing agent such as polyglycol ether) according to various purposes as far as the mode of operation and the effect of the above diesel fuel additive composition are preserved.
- In the scouring method according to the second aspect of the invention, the scouring is, as described above, carried out by adding the diesel fuel additive composition according to the first aspect of the invention at 0.5 to 2% by weight to diesel fuel.
- If the content of the above fuel additive in the diesel fuel is less than 0.5% by weight, sufficient detergency may not be obtained. On the other hand, if the content of the above fuel additive is more than 2% by weight, the water content in the fuel increases, and an adverse effect may be exerted on the system using the above object to be scoured, for example, leading to corrosion of the object to be scoured.
- The above scouring method can be carried out by pouring the diesel fuel additive composition into a fuel tank of the diesel engine, to thereby add the diesel fuel additive composition to diesel fuel, or by using diesel fuel blended with the diesel fuel additive composition beforehand.

- In the low-temperature fluidity marginal valuation tests, the low-temperature fluidity margin was evaluated for each sample by testing whether the samples were flowable at -5°C or not.
- When the sample was flowable at -5°C, the evaluation is represented by "F", and when the sample was not flowable at -5°C, the evaluation is represented by "NF".
- The results are shown in Table 3.
(Table 3) Diesel fuel additive composition (Sample No.) Low-temperature fluidity marginal evaluation E1 F E2 F E3 F E4 F E5 F E6 F C9 NF - As can be seen in Table 3, Samples E1 to E6 as the embodiments of the present invention are superior in terms of the low-temperature fluidity margin.
- Sample C9 as the comparative example was not flow-movable at -5°C, since the content of the component (a) was more than the upper limit defined in the present invention.
- Then, the diesel fuel compositions (Diesel fuel compositions 1 to 17) shown in Table 4 were prepared by blending the respective diesel fuel additive compositions (Samples E1 to E6, and Samples C1 to C10) at 1% by weight to diesel fuel.
- Diesel fuel composition 7 does not contain any diesel fuel additive composition, and comprises 100% diesel fuel.
- Subsequently, evaluations for detergency, stability, and corrosivity were carried out for the obtained diesel fuel compositions (Diesel fuel compositions 1 to 17).
- The results are shown in Table 4.
- To evaluate detergency, the needle part to which deposits (a mixture of polymer-substance derived deposits, water-soluble deposits, and water-insoluble deposits) adhered was removed from the injector of a vehicle equipped with a fuel injecting system. The needle part was then immersed in the individual diesel fuel compositions (Diesel fuel compositions 1 to 17) for 24 hrs, and the extent to which the deposits were removed was evaluated visually.
-
- AA: Almost all of the deposits were removed.
- A: Most of deposits were removed.
- x: The amount of the removed deposits was small.
- y: The deposits were viscous.
- z: The deposits were barely removed.
- It is assumed that the evaluations represented by AA or A were good and acceptable, and the evaluations represented by x, y, or z were bad and unacceptable.
- Stability was evaluated by visually observing the dispersability of the diesel fuel additive compositions, when the above diesel fuel additive compositions (Samples E1 to E6, and Samples C1 to C10) were added to diesel fuel.
- It is assumed that the samples in which no water separation was recognized were good and acceptable (evaluated as G), and the samples in which water separation was recognized were bad and unacceptable (evaluated as u).
- To evaluate corrosivity, filter papers were laid on Petri dishes 6 cm in diameter, and 5 g of swarf of ground cast iron (FC200) was set on the filter papers. The above diesel fuel compositions (Diesel fuel compositions 1 to 17) were introduced in the Petri dishes, followed by a 10 minute immersion of the cast iron swarf therein, and then the test solutions were removed by decantation. Subsequently, the subjects were stored in a container at 20°C at 60% humidity. The state of rust formed on the ground cast iron swarf was observed to evaluate the corrosivity.
- It is assumed that cases in which no rust was recognized were good and acceptable (evaluated as G), and cases in which the formation of rust was recognized were bad and unacceptable (evaluated as u).
- As can be seen in Table 4, Diesel fuel compositions 1 to 6 as the embodiments of the present invention showed a good detergency.
- As may be understood from the foregoing, the present invention can provide a diesel fuel additive composition that is stably dispersed in diesel fuel, removes polymer-substance derived deposits, water-soluble deposits, and water-insoluble deposits at once, and does not cause any adverse effect on the object to be scoured.
- It was found in Table 4 that Diesel fuel composition 7 as a comparative example, which did not contain a diesel fuel additive composition, was bad and unacceptable in terms of detergency.
- Diesel fuel composition 8 as a comparative example, which used Sample C1 of which the content of the component (b) is below the lower limit defined in the present invention as a diesel fuel additive composition, was bad and unacceptable in terms of detergency and stability.
- Diesel fuel composition 9 as a comparative example, which used Sample C2 of which the content of the component (c) is below the lower limit defined in the present invention as a diesel fuel additive composition, was bad and unacceptable in terms of detergency.
- Diesel fuel composition 10 as a comparative example, which used Sample C3 of which the content of the component (d) is below the lower limit defined in the present invention as a diesel fuel additive composition was bad and unacceptable in terms of detergency and stability.
