Gasoline of high proportion methanol directly used for vehicle

Abstract

The invention discloses gasoline of high proportion methanol directly used for a vehicle. The methanol mass fraction is not less than 70%. The methanol gasoline comprises: 70-90% of methanol, 7-29% of component oil and 1 to 3% of additive, wherein, the component oil comprises C5-C7 saturated alkane, solvent oil, 90 # gasoline and toluene, the additive comprises C3-C8 monobasic alcohol, petroleum ether with distillation range of 30-60 degrees C., EGME, N, N'-2 salicylidene -1,2- propylene diamine and other raw materials which can be added or not. The provided gasoline of high proportion methanol directly used for the vehicle in the invention overcomes the existing technical problem of the gasoline of high proportion methanol under the circumstances that the existing engine is not required to be modified, and leads the gasoline of high proportion methanol to be well applied to the vehicle.

Description

technical field [0001] The invention belongs to the technical field of methanol fuel, and relates to methanol gasoline for vehicles, in particular to methanol gasoline with a high proportion for vehicles. Background technique [0002] The world's energy reserves are becoming increasingly scarce and environmental problems are becoming more and more serious. Energy and environmental issues have attracted great attention from all countries in the world. Therefore, seeking new clean alternative energy has become a global issue. my country's economy is developing at a high speed. At present, there are more than 70 million automobiles, and most of the oil consumed every year needs to be imported. Energy and environmental issues restrict the rapid development of my country's economy. [0003] Gasoline has always been the main fuel for light vehicles, but this usage pattern is increasingly constrained by environmental pollution and resource scarcity. In order to improve this dilem...

AI Technical Summary

Problems solved by technology

There is still a serious problem in the promotion process of low-proportion methanol gasoline---the saturated vapor pressure is high, and in high-temperature weather, it is easy to have the problem that the tanker cannot add fuel and the car "wheezes". This problem seriously restricts the low-proportion The Promotion of Methanol Gasoline in the Country, Especially in the South

[0006] Although the high-proportion methanol gasoline does not have the above-mentioned "air lock" problem, the current high-proportion methanol gasoline needs to change the engine when it is applied, and the user's investment is relatively large, which is not conducive to large-scale promotion

The problems of high-proportion methanol gasoline also include the difficulty of cold start in winter in the north, and it is basically impossible to start at -25°C; when it is used in the rainy season in the south, it will be separated from the water phase, which will affect the use of the car; long-term use will corrode the engine and oil delivery system
