Abstract

The invention relates to a multifunctional alcohol fuel additive, aiming at resolving such technical problems existing in prior alcohol fuel as the mutual solubility, the power performance and the stability are poor, cleaning degrees of oil products and fuel oil system are poor and the corrosion and the air resistance of methanol gasoline can not be effectively handled. The additive comprises following components in portion by volume: 50 to 60 portions of cosolvent, 5 to 10 portions of corrosion inhibitor, 0 to 30 portions of detergent dispersant, 0 to 10 portions of rubber plasticizer and 0 to 15 portions of vapor pressure inhibitor. The additive has the advantages of high octane value, strong power performance, good stability, desirable mutual solubility, environmental protection and energy conservation, and can effectively inhibit metallic corrosion, improve the cleanness of oil products and resolve the problems of air resistance.

Description

technical field [0001] The invention relates to an alcohol fuel additive, in particular to an alcohol fuel additive which improves the mutual solubility of methanol and gasoline, prevents metal corrosion and inhibits rubber swelling. Background technique [0002] Alcohol fuel refers to gasoline containing a certain proportion of methanol or ethanol. Methanol, as a new type of energy to replace traditional fuels, can be blended with gasoline and diesel, and can also be used directly as a fuel. Its advantages in environmental protection, power, and economy are universally recognized. Methanol is considered to be "the cleanest automobile engine fuel in the world is methanol fuel", "the future automobile engine fuel is methanol fuel" and so on. [0003] In the modulation process or actual operation of methanol-gasoline fuel, there are also some problems, such as: methanol-gasoline miscibility, low-temperature anti-phase delamination, cold start, high-temperature air resistance,...
