Ethanol-diesel mixed fuel formula

Abstract

The invention provides a mixed fuel formula of ethanol and diesel oil, comprising industrial ethanol with the volume ratio of 10-30 percent and the purity of 99.5 percent, commercial 0 model diesel with the volume ratio of 87.9-63.7 percent, direct-chain saturated fatty alcohol or the mixture thereof with the volume ratio of 2-6 percent and the carbon atomicity of 8-12, and commercial cetane number improver with the volume ratio of 0.1-0.3 percent. The formula adds the solubilizer and cetane number improver of low proportion into the mixed fuel of ethanol and diesel, so as to keep long-term stability without lamination and recover the cetane value to the level of the diesel, thus leading the engine to work stably and reliably, and greatly reducing the exhaust pollution.

Description

technical field [0001] The invention relates to a mixed power fuel, in particular to an ethanol diesel mixed fuel formula, which belongs to the category of energy application development technology and combustion technology. Background technique [0002] When the internal combustion engine burns, it will produce a variety of harmful substances, such as carbon monoxide (CO), hydrocarbons (HC), and nitrogen oxides (NOx). For diesel engines, due to simultaneous mixing and combustion, local over-rich mixtures will inevitably be formed, which will produce soot formed by incomplete combustion; at the same time, due to excessive air, the high temperature generated by combustion will promote the formation of nitrogen oxides . Due to the contradictory mechanisms of these two emissions, it is difficult to reduce both emissions simultaneously. Ethanol is a clean alternative fuel that has been hotly researched in recent years. It has a high oxygen content and is beneficial to reducing...
