As is well known, when oil is used as a fuel and is atomized and combusted, the finer the atomized fuel particles are, the more vaporization is promoted and the combustion efficiency is increased. For this reason, improvements have been made to vaporizers and atomizers in the past. In automobile carburetors, fuel is primarily mixed with air by air bleed, and then the emulsified fuel is ejected from a nozzle.

However, it is possible to improve the atomization of fuel oil by improving devices such as the above-mentioned carburetor.
This method attempts to promote the miniaturization of mist droplets by external means, and there is a problem in that further promotion tends to be limited due to the relationship with other factors such as the air-fuel ratio.

燃料油を霧化する場合、霧粒が微細化し易くなる
ことに着眼し、表面張力を低下して霧粒の微細化

ることを目的とするものである。 The present invention focuses on the fact that when the surface tension of fuel oil is reduced, when the fuel oil is atomized, it becomes easier to make the mist particles finer, and the present invention can promote the miniaturization of the mist particles by reducing the surface tension. The purpose is to provide fuel oil with improved combustion efficiency.

That is, the gist of the present invention is a fuel oil characterized by adding a small amount of fluorine-based surfactant to petroleum-based fuel oil.

販の弗素系界面活性剤は殆んど全部使用できる
が、サーフロン（登録商標名、旭硝子株式会社）、
フロラード（登録商標名、住友スリーエム株式会
社）が代表例として挙げられる。 The fluorine-based surfactant used is known per se, and is one in which part or all of the H bonded to C of the hydrophobic group of a normal surfactant is replaced with F. . While most ordinary surfactants have a hydrophobic group with a C number of 12 to 20,
Fluorine-based compounds exhibit significant surface activity at positions 7-10. Therefore, it is preferable that the surfactant to be used has a C number of 7 to 10, for example,
C 8 F 17 COONH 4 , C 8 F 17 CONH (CH 2 ) 5 COONH 4 ,
Examples include C 9 F 19 CONH (CH 2 ) 3 N (CH 2 ) 3 I, and almost all commercially available fluorine-based surfactants can be used, but Surflon (registered trademark name, Asahi Glass Co., Ltd.),
Florado (registered trademark name, Sumitomo 3M Ltd.) is a typical example.
弗素系界面活性剤の添加量は0.002％（重量％、
以下同じ）程度が特に好ましく、0.002％〜0.003

もその作用が認められる。 The amount of fluorine surfactant added is 0.002% (wt%,
The same applies hereafter) is particularly preferable, and 0.002% to 0.003
% is suitable; beyond this range, the effect of lowering the surface tension of petroleum fuel oil remains almost the same;
On the other hand, if the content is lower than the above range, the effect of lowering the surface tension of petroleum fuel oil gradually decreases, but this effect is still observed even at 0.00002%.

When a fluorine-based surfactant is added to petroleum-based fuel oil, the fluorine-based surfactant exhibits surfactant power even in the petroleum-based fuel oil, and the surface tension of the petroleum-based fuel oil is significantly reduced. If the lipophilic group of the surfactant is the same as that of petroleum-based fuel oil, the surfactant's active power will hardly work in the petroleum-based fuel oil, but if the lipophilic group of the surfactant is a fluorine-based surfactant, it will not work in petroleum-based fuel oil. Since fluorine-based surfactants are different from petroleum-based fuel oils, it is thought that fluorine-based surfactants exhibit surfactant power even in petroleum-based fuel oils and work to lower the surface tension of the petroleum-based fuel oil. It will be done.

焼効率が改善されるものと考えられる。 This is because the surface tension of the fuel oil of the present invention is lowered by the fluorine-based surfactant, which makes the mist droplets finer during the above-mentioned atomization, promoting vaporization and improving combustion efficiency. it is conceivable that.

の微細化を一層促進するものと考えられる。 When petroleum fuel oil is atomized under pressure, its components are separated into light and heavy components. That is, the light components become fine mist droplets, and the heavy components become coarse mist droplets and are separated. This separation prevents the promotion of vaporization of the mist particles and prevents the overall combustion efficiency of the fuel. However, according to the present invention, petroleum-based fuel oil is preferably used with a fluorine-based surfactant to reduce the above-mentioned surface tension compared to light components. Since the surface tension of heavy components tends to decrease at a higher rate during the injection process, the separation of heavy and light components due to the size of the mist droplets during the above injection is extremely minimized, and the fineness of the mist droplets of the entire fuel is reduced. It is thought that this will further promote the development of

When 0.002% of S-381 in Surflon was added as a fluorine-based surfactant to this, the surface tension of the gasoline was 25 dynes/cm.

同様の結果が得られた。 It should be noted that even when the above-mentioned fluorine-based surfactants other than those mentioned above were used, substantially the same results as in the above example were obtained, and even when light oil was used as the petroleum-based fuel oil, substantially the same results as in the above example were obtained.

In this way, in the present invention, the surface tension of petroleum fuel oil is significantly reduced by the added fluorine-based surfactant, and therefore, when atomized during use, the mist particles become finer and vaporization is promoted. Combustion efficiency can be improved.
