Problems solved by technology

[0003] When there is more and more accumulated water at the bottom of the fuel tank, the oil level is very low and the fuel cannot be refueled in time, the oil pump will directly pump the accumulated water at the bottom of the fuel tank into the engine, which will affect the normal fuel supply of the fuel system and cause poor fuel combustion. As a result, the engine has troubles such as difficulty in starting, unstable idling, panting, poor acceleration or flameout, and sometimes even damages fuel system components; in winter, when the temperature is lower than the freezing point of water, the water will condense and freeze , causing the blockage of the oil circuit and making the engine unable to work; in addition, the accumulated water in the fuel tank may also cause the inner wall of the fuel tank to rus...

Embodiment 1

[0068] Prepare fuel additive sample 1 and sample 2 according to the composition shown in Table 5, and measure the solubilization performance of these samples according to the test method for solubilization performance, and the results are listed in Table 5.

[0069] table 5

[0070]

[0071] As can be seen from Table 5, the sample 1 that adopts IOA and the sample 2 that adopts IHA all have good solubilizing properties.

Embodiment 2

[0073] Prepare fuel additive sample 1 and samples 3-9 according to the composition shown in Table 6, and measure the solubilization performance of these samples according to the test method for solubilization performance, and the results are listed in Table 6.

[0074] Table 6

[0075]

[0076] It can be seen from Table 6 that sample 1 and samples 3-9 all have good solubilizing properties. It is worth noting that when the content of emulsifier IOA is low (sample 3, 4 and 6), the solubilization performance evaluation results of these samples to EG and E10G90 are "effective", and the solubilization performance evaluation results to GA (At this time, the overall evaluation result of the solubilization performance of these samples is still "effective"), this is because when the content of emulsifier is low, the solubilization effect of the samples on the water in the fuel is relatively weak. Weak, so, the content of emulsifier in the fuel additive provided by the present inven...

Abstract

The invention relates to a fuel oil additive. The fuel oil additive includes C12-C18 isomeric saturated fatty acid as an emulsifier, a neutralizer used for forming salt together with the fatty acid, and an optionally selected diluent. The fuel oil additive can effectively dissolve a tiny amount of water in gasoline or a fuel tank, and has a better effect than routine fatty acids.

Description

technical field [0001] The invention relates to a fuel additive, in particular to a fuel additive capable of solubilizing water. Background technique [0002] Gasoline often contains some moisture, some of which are produced during the refining process of gasoline, and some of which are formed by certain external factors. At normal temperature, fuel can dissolve some water, but when the temperature drops, the solubility of water decreases accordingly, and the excess dissolved water will be dispersed. Due to the relatively high specific gravity of water, water will be deposited at the bottom of the fuel tank and will not be consumed with fuel consumption, thus accumulating more and more. In addition, due to the temperature difference between the inside and outside of the fuel tank, the water vapor in the air will condense into liquid water and deposit in the fuel tank. As the fuel is consumed, the fuel tank will inhale air to fill the gap, so the higher the air humidity, the...
