Problems solved by technology

[0005] In previous plateau oxygenated fuel studies, some researchers have carried out adding methanol, ethanol, dimethyl carbonate, dimethyl ether, 2-methoxyethyl acetate, 2-ethoxyethyl acetate to diesel oil. Research on oxygen-containing compounds such as esters, these compounds can play a certain role in promoting combustion and reducing black smoke emissions, but due to their low cetane number, low flash point, and poor miscibility with diesel oil, they are not suitable as high-altitude Oxygenated Diesel Use

Abstract

The invention discloses polymethoxy dialkyl ether-type oxygen-containing diesel for a plateau section. The polymethoxy dialkyl ether-type oxygen-containing diesel is characterized by consisting of the following components in percentage by volume: 30%-100% of polymethoxydialkyl ether and 0-70% of diesel, wherein the polymethoxydialkyl ether consists of one or more of polymethoxy dimethyl ether, polymethoxy diethyl ether, polymethoxy dipropyl ether, polymethoxy dibutyl ether, polymethoxy diamyl ether, polymethoxy dihexyl ether, polymethoxy diheptyl ether, polymethoxy dioctyl ether, polymethoxy dinonyl ether, and polymethoxy didecyl ether. According to the polymethoxy dialkyl ether-type oxygen-containing diesel for a plateau section disclosed by the invention, incomplete combustion of the diesel caused by anoxia on the plateau can be effectively relieved, the dynamic performance of a diesel engine can be improved, the emission of exhaust fumes can be greatly reduced, heat load can be reduced, the service life of the engine can be prolonged, the failure rate can be reduced, equipment maintenance costs can be reduced, social and economic benefits are high and practicality is high.

Description

technical field [0001] The invention belongs to the field of energy and chemical industry, and in particular relates to a polymethoxy dialkyl ether type oxygen-containing diesel oil for plateau areas. Background technique [0002] When diesel vehicles are running in plateau areas, due to the thin air, low atmospheric pressure, low oxygen intake, and incomplete fuel combustion, there will be a significant drop in power performance, serious black smoke, and shortened service life. Taking the area at an altitude of 4500m as an example, the atmospheric pressure is only 57% of that of the plain area, the oxygen content is only 48% of that of the plain area, and the power of diesel vehicles drops by more than 35%. [0003] Oxygenated fuel and diesel are blended according to a certain ratio, and the use in plateau areas can improve the power of the engine, reduce black smoke emissions, and increase the service life of the engine. [0004] Polymethoxydialkyl ethers, whose general c...
