Methanol gasoline cosolvent

Abstract

The invention discloses a methanol gasoline cosolvent. The methanol gasoline cosolvent is prepared by mixing the following components in volume fraction: 30-50% of C3-6 fatty alcohol, 4-12% of dimethyl carbonate, 30-40% of methyl tertiary butyl ether and 10-25% of alkyl glycoside, and the dosage of the methanol gasoline cosolvent accounts of 1-2% of the total volume of prepared methanol gasoline. After the cosolvent disclosed by the invention is added in the methanol gasoline, the solubilization water resistance of the methanol gasoline reaches 4-6%, the methanol gasoline is clear and transparent, is free of layering and is long in stable phase, and carbon deposits at various positions of a combustion system can be effectively removed to avoid such phenomena as power reduction and insufficient combustion caused by the carbon deposits, so that the engine performance is improved.

Description

technical field [0001] The invention relates to an alcohol ether fuel additive for vehicles, in particular to a cosolvent for improving the phase separation resistance of methanol gasoline. Background technique [0002] With the proposal of energy conservation, environmental protection and low-carbon economy, methanol gasoline has received extensive attention as an alternative fuel for vehicles. When methanol gasoline is used as vehicle fuel, the phase stability problem of the methanol-gasoline system should be solved first. The stratification of methanol gasoline can cause the engine to stop working; secondly, the detergency of methanol gasoline is also very important, and gasoline deposits will Lead to adverse consequences such as poor engine drive, reduced fuel economy, increased fuel consumption, and worsened emissions. [0003] At present, some co-solvent products have been developed in the domestic methanol gasoline market, most of which are composed of different orga...

Problems solved by technology

When methanol gasoline is used as vehicle fuel, the phase stability problem of the methanol-gasoline system should be solved first. The stratification of methanol gasoline can cause the engine to stop working; secondly, the detergency of methanol gasoline is also very important, and gasoline deposits will Lead to adverse consequences such as poor engine drive, reduced fuel economy, increased fuel consumption, and worsened emissions

[0003] At present, some co-solvent products have been developed in the domestic methanol gasoline market, most of which are composed of different organic substances such as polyols, aromatic hydrocarbons, esters and ethers. The promotion and application of methanol gasoline has been limited by problems such as insufficient fuel consumption, increased carbon deposits in the combustion system, and damage to the three-way catalyst.
