Problems solved by technology

[0003] One is that the power performance of methanol fuel is lower than that of diesel; the other is that the cetane number is low, only 2 to 3, and the cetane number of the diesel engine cannot be less than 45 when it is compressed and started;
[0004] The third is that methanol has a swelling and corrosion effect on non-metallic parts of the engine system, while there is a potential corrosion problem on metal parts;
[0005] The fourth is that the viscosity coefficient of methanol is small, so it has a certain flushing effect on the engine system;
[0006] The fifth is the compatibility between methanol and diesel oil, which will separate when it meets water, and the storage stability is poor
But some existing methanol fuel a

Abstract

The invention belongs to the technical field of fuel additive, and particularly relates to a methanol fuel additive for diesel engines. The methanol fuel additive is prepared from the following raw materials in parts by weight: 10 to 25 parts of a cosolvent, 5 to 15 parts of 2-hydroxysuccinic acid, 3 to 11 parts of glycerol dimethacrylate, 2 to 9 parts of glyceryl polyoxyethyl ether, 2 to 8 parts of dioctyl phthalate, 2 to 7 parts of methyl cyclopentadiene, 1 to 8 parts of carboxymethylcellulose, 1 to 7 parts of diethylene glycol dinitrate, 1 to 5 parts of tert-pentyl methyl ether, and 1 to 6 parts of an antioxidant. The methanol fuel additive effectively improves the power and the cetane number of methanol fuel, effectively solves the problems of swelling and corrosion, and improves the solubility and the storage stability of methanol and diesel oil.

Description

technical field [0001] The invention belongs to the technical field of fuel additives, in particular to a methanol fuel additive for diesel engines. Background technique [0002] With the depletion of petroleum resources, people are trying to find its substitutes. Methanol is regarded as the potential preferred liquid fuel to replace gasoline and diesel because of its cleanliness, high calorific value, high efficiency and easy availability. Some countries have used it as a practical liquid fuel for vehicles. There are many examples of using methanol as a gasoline substitute in China. As a diesel substitute, it is being explored. The main problems of methanol used as vehicle engine fuel: [0003] One is that the power performance of methanol fuel is lower than that of diesel; the other is that the cetane number is low, only 2 to 3, and the cetane number of the diesel engine cannot be less than 45 when it is compressed and started; [0004] The third is that methanol has ...
