Additive of M50 methanol gasoline

Abstract

The invention relates to an additive of fuel, in particular to an additive of high-proportion methanol gasoline, such as M50 methanol gasoline. The additive is characterized in that the additive in the total volume ranging from 2% to 5% is added into the methanol gasoline and consists of 60% to 70% of mutual solvent formed by compounding alcohols, alcohol ethers, esters and acetones according to optional proportion, 24.4% to 30% of ignition agent formed by compounding fatty hydrocarbons, aromatic hydrocarbons and methyl tertiary butyl ether according to optional proportion, 4% to 6% of combustion improver formed by compounding nitryls and nitrate esters according to optional proportion, 1% to 3% of corrosion inhibitor formed by compounding phenols and grease according to optional proportion, and catalyst and anti-oxidant stabilizer in proper quantity. By the aid of the additive, the service life of a gasoline tank can be prolonged evidently, methyl alcohol system of the gasoline can be effectively guaranteed against being deteriorated and layered easily, and the problems of poor startability and power performance and the like can be solved effectively. The additive is rich in raw material sources, simple in production process and procedures and convenient in use and popularization.

Description

technical field [0001] The present invention relates to a kind of fuel additive, especially the additive of M50 methanol gasoline fuel. Background technique [0002] The use of methanol fuel in gasoline engines has gradually developed from a low proportion of methanol content of 15% (M15) to a high proportion of methanol content of 85-100% (M85-M100) in the late 1980s. It's been a pretty difficult process. With the popularization of automobiles and the increasingly serious shortage of oil, the sharp rise in the price of refined oil, and the increasing pressure on environmental protection and other factors, the research and development of oil substitutes has become one of the hot spots in recent years. [0003] Because the physical and chemical properties of methanol fuel are close to gasoline, using methanol fuel on gasoline engines does not require major changes in the engine. In addition, methanol is a liquid that facilitates product transportation. Even for long-distance...

AI Technical Summary

Problems solved by technology

At present, the single methanol as a fuel mainly has the following problems: First, the latent heat of evaporation of pure methanol is relatively high, which is 1178 kJ / kg, while gasoline is only 330-420 kJ / kg, and it will become cool under the condition of adiabatic temperature of 122°C. Mixture temperature drops more than gasoline

[0004] M50 methanol gasoline, as the name implies, is a mixed system of methanol with a volume content of 45-50% and gasoline with a volume content of 50-55%. Third, the current additives cannot effectively ensure the poor miscibility of gasoline and methanol, resulting in the stratification of gasoline and methanol, making the car unable to use normally, etc.
