Technical Field

The invention relates to the field of ethanol gasoline additives for vehicles, in particular to an ethanol gasoline cleaning protective agent.

Background

The ethanol gasoline is a new type of alternative energy source formed by mixing ethanol and common gasoline in a certain proportion. According to national standard of China, the ethanol gasoline is prepared by blending 90% of common gasoline and 10% of fuel ethanol.

According to related research data, the oxygen content in the gasoline can be improved by 3.5% only by the gasoline containing 10% of ethanol, the improvement of the oxygen content can enable the gasoline to be combusted more fully, and the octane number in the ethanol gasoline is higher, so that the antiknock performance is more excellent. By taking common gasoline as an example, compared with No. 92 gasoline and No. 95 gasoline, the octane number of the ethanol gasoline is as high as more than 110, and the antiknock performance is extremely superior.

From the aspects of emission control and environmental protection, compared with the conventional gasoline, the gasoline containing 6 percent of ethanol has the advantages that the emission of hydrocarbon can be reduced by 5 percent, the emission of carbon monoxide can be reduced by 21 to 28 percent, the emission of nitrogen oxide can be reduced by 7 to 16 percent, and the emission of toxic gas can be reduced by 9 to 92 percent. However, since the calorific value of ethanol is 60% of that of gasoline of a conventional vehicle, the fuel consumption of the engine will be increased by more than 5% according to the measured relevant data under the condition that the vehicle uses the ethanol gasoline without any modification. In addition, the shelf life of ethanol gasoline is relatively low, and the ethanol gasoline needs to be completely combusted within one month as much as possible after a tank of ethanol gasoline is filled, otherwise, the ethanol can be oxidized and has a small amount of water, and the engine effect is influenced after the ethanol is oxidized for a long time.

The ethanol gasoline has the characteristics of swelling property, high evaporation latent heat and water generation after combustion, and the swelling property can accelerate the aging of rubber parts, particularly oil pipelines. However, with the gradual popularization of ethanol gasoline, as an automobile manufacturer, key technical tests must be upgraded to meet the use characteristics of the ethanol gasoline; in a short time, the vehicle type mainly using the conventional vehicle type can be influenced to a certain extent, but in the long run, the popularization of the ethanol gasoline is absolutely beneficial and harmless to the national environment protection in large measure.
