Abstract

Provided is a low-temperature cosolvent of a polyoxymethylene dimethyl ether and diesel oil mixed fuel and a preparation method of the low-temperature cosolvent, wherein the cosolvent comprises the components in parts by volume: 10 to 20 parts of castor oil, 5 to 10 parts of n-amyl alcohol, 10 to 15 parts of n-hexyl alcohol, 15 to 25 parts of n-heptanol, 25 to 45 parts of n-octyl alcohol and 5 to15 parts of an ethylene-vinyl acetate copolymer. The preparation method comprises the steps: adding n-amyl alcohol into castor oil at room temperature to form a mixed solution, adding n-hexyl alcohol,n-heptanol and n-octanol into the mixed solution in the stirring process, and uniformly mixing, and gradually adding the ethylene-vinyl acetate copolymer in batches in the adding process. According to the low-temperature cosolvent, the mixed fuel can be mutually dissolved in any proportion in low-temperature environments such as high and cold environments and winter environments and can stably coexist for a long time.

Description

technical field [0001] The invention belongs to the field of fuels, and relates to a low-temperature auxiliary solvent for mixed fuel of polyoxymethylene dimethyl ether and diesel oil and a preparation method thereof. Background technique [0002] In the field of commercial vehicles in my country, diesel vehicles have an absolute advantage due to their good power economy, but their NOx and PM emissions are important sources of smog and have become the focus of attention of the whole society. In order to cope with the National VI emission regulations that will be implemented in 2020, major technical upgrades are required for the structure of the diesel engine, electronically controlled fuel injection system, in-cylinder combustion organization, and exhaust after-treatment system, which will greatly increase technical difficulty and product quality. The price and use cost, and the application of clean alternative fuels can minimize the cost of engine technology, development an...
