Novel fuel for vehicles

Abstract

The invention discloses a novel fuel for vehicles. The novel fuel comprises the following components in percentage by weight: 10%-45% of alcohol substances, 1%-3% of emulsifying agent, 15%-45% of heavy aromatic, 15%-35% of solvent oil and 8%-30% of dimethyl ether, wherein the alcohol substances are methanol, tert-butyl alcohol or cyclohexanol; the emulsifying agent is a mixture of oleic acid, ethyl ether, methyl benzoate and acetone; the heavy aromatic is a mixture of dimethylbenzene, 180# aromatic solvent oil and 220# aromatic solvent oil. Compared with the prior art, the novel fuel disclosed by the invention is simple in composition. According to the novel fuel, the combustion of the obtained fuel is more complete due to the added polymethoxy dimethyl ether, so that the smoke intensity of a tail gas is greatly reduced; the flash point of the obtained fuel can reach 55-60 DEG C, the cetane number can reach 60-80, and the water resistance can reach 10%-15%; the storage period can reach more than one year, and no lamination or polymethoxy is generated; the copper corrosion reaches a 1a grade.

Description

technical field [0001] The invention relates to a motor vehicle fuel, in particular to a new vehicle fuel suitable for diesel engines. Background technique [0002] With the rapid development of the national economy and the improvement of people's living standards, my country's demand for energy is increasing day by day, and the consumption of liquid fuels that use petroleum as raw material continues to increase. At the same time, traditional oil resources are increasingly scarce. Therefore, research and development of alternative fuels is imperative. The development trend of international vehicle fuels and my country's energy sources both clearly point out that automobiles should gradually reduce the use of fossil fuels and increase the consumption of alcohol fuels and biofuels. Hamelinck pointed out that currently methanol and Fischer-Tropsch synthetic fuels are the best power fuels. [0003] Diesel engines have higher thermal efficiency than gasoline engines, low-speed...

AI Technical Summary

Problems solved by technology

[0004] There are many methanol-diesel technical schemes that have been disclosed, such as the invention patent with the publication number CN101024784A, although the addition ratio of methanol can reach more than 50%, but the cetane number of the fuel obtained by this technical scheme is low and the ignitability is poor

Another example is the methanol diesel disclosed in the invention patent with publication number CN101886000A, which has a higher flash point than the aforementioned patent, and has a cetane number of 40-50, a water resistance of 3-15%, and lower corrosion properties, but its cetane number is still not ideal
