Abstract

The invention provides a methanol gasoline additive. The additive comprises the following components in parts by weight: 22-28 parts of 3-methyl-1-butanol, 12-15 parts of 1-methoxy-2-propanol, 8-10 parts of propylene glycol methyl ether acetate, 4-6 parts of tert-butyl methyl ether, 3-5 parts of isooctyl phosphate, 3-5 parts of polyethylene glycol tert-octylphenyl ether, 6-8 parts of hexaethylene glycol monodecyl ether, 4-6 parts of 1H-benzotriazole, and 6-8 parts of triethylene glycol monobutyl ether. The methanol gasoline additive is prepared by composite stirring of each component with obvious synergistic effects; the additive realizes the effect that corrosion of automobile metal due to methanol gasoline in usage process is reduced, and at the same time compared with 93# gasoline and common M30 gasoline, the additive improves combustion efficiency of methanol gasoline and enhances power.

Description

technical field [0001] The invention relates to a fuel oil additive for vehicles, in particular to an additive for methanol gasoline. technical background [0002] Methanol is industrial methanol synthesized from coal, coke, natural gas, light oil, heavy oil, etc. The nature of methanol: industrial methanol is toxic, flammable, and explosive. At normal temperature and pressure, methanol is a colorless, transparent, mobile and volatile liquid with an odor similar to ethanol. Whether methanol gasoline can replace gasoline and diesel in terms of power performance. Methanol gasoline needs to be configured from methanol, gasoline and core additives, and the technology of methanol gasoline is mature. The amount of methanol incorporated is generally 5% to 30%. The one with 15% blending is the most, which is called M15 methanol gasoline. The anti-knock performance is good, the research octane number (RON) increases with the increase of the amount of methanol mixed, and the motor...
