Problems solved by technology

[0004] (2) Since methanol fuel and gasoline are two different fuels with different physical and chemical properties, the combustion is not synchronized, so the power is small, the fuel consumption is large, knocking is easy to occur, and the combustion is not sufficient
[0005] (3) Alcohol swelling is very strong, plastics and rubber are exposed to methanol, and it is easy to swell
[0008] (6) The standards for various manufacturing materials and processes of gasoline-burning vehicle engines and oil pipes are corresponding to existing gasoline. To burn a large proportion of methanol fuel, the engine and fuel supply system need to be modified.

Abstract

The invention relates to an oil additive and particularly discloses a methanol fuel additive and methanol gasoline prepared with the same. The methanol fuel additive comprises the following components in parts by weight: 15.9 to 20 parts of modifier, 8 to 12 parts of oxidant, 12 to 8 parts of activating agent, 15 to 17 parts of antiknock, 0.54 to 2.48 parts of cleaning agent, 40.5 to 34.5 parts of catalyst, 8 to 6 parts of corrosion inhibitor and 0.06 to 0.02 part of anti-attrition lubricant. According to the methanol gasoline prepared with the additive, methanol and gasoline can be completely soluble or instantly soluble after being mixed, so that the methanol gasoline is clear and bright in appearance, is not layered and is free from impurities; and the methanol gasoline has the characteristics of high octane value, stable burning, sufficient power and tiny contained colloid in running tests and examination, causes no corrosion and swelling reaction on materials of the conventional gasoline car, and can be mixed with unleaded gasoline for use or directly used on the premise of not changing an engine and an oil supply system of the conventional gasoline car.

Description

technical field [0001] The invention relates to an oil additive, in particular to a methanol fuel additive and methanol gasoline prepared therefrom. Background technique [0002] Methanol fuel is a world-recognized environmentally friendly clean fuel. Authoritative experts predict that it will be the best alternative fuel for fossil fuels in the next 20-30 years. However, the current methanol fuel still has the following problems: [0003] (1) Methanol fuel is a mixed fuel of methanol and gasoline. According to the chemical "similar compatibility" principle, methanol is an alcohol and gasoline is a hydrocarbon. The chemical structures of the two are different, so methanol and gasoline are incompatible with each other. [0004] (2) Since methanol fuel and gasoline are two different fuels with different physical and chemical properties, the combustion is not synchronized, so the power is small, the fuel consumption is large, knocking is easy to occur, and the combustion is ins...
