Fuel oil for green-energy vehicles

Abstract

The invention relates to fuels, in particular to alcohol hydrocarbon biosynthesized fuel oil for green-energy vehicles. The fuel oil is prepared from, by weight, 20-50% of denatured methyl alcohol, 2%-5% of a phase solvent, 3%o-5%o of a modifying agent and the balance gasoline 92# or 95# in national gasoline standard IV, wherein the phase solvent is a biolipid additive, and the denatured methyl alcohol is a CH3(OH) condensation compound of monocarbon. The fuel oil for the green-energy vehicles has advantages that the fuel oil can be applied to high-compression-ratio vehicles to directly take place of gasoline 92# or 95# in national gasoline standard V without engine modification; the fuel oil is available for mutual dissolution with vehicular gasoline 93#, 97# and 98# in international standard according to any proportions; exhaust emission of carbon monoxide, sulfur dioxide, oxynitride (NOx) and PM2.5 is reduced by more than 50% on average as compared with that of normal gasoline; the fuel oil can be used both in hot summer and cold winter and even in plateau regions, and gas blockage of oil ways of the vehicles is avoided; the fuel oil is low in additive consumption, effective and low in cost.

technical field [0001] The invention relates to fuels, in particular to an alcohol hydrocarbon and biosynthesized fuel oil for green energy vehicles. Background technique [0002] In the current prior art, there are many types of synthetic fuel oils utilizing alcohol hydrocarbons, such as methanol gasoline in various proportions, but there are common defects: one, methanol is hydrophilic, and methanol gasoline is separated from water. Generally, existing products only It can control the encounter of 0.5%-1% water without phase separation, and the water is dispersed in the mother liquor in a microemulsified state. In addition, since the calorific value of methanol is only half of that of gasoline, and the gasoline mixture requires an increase in calorific value, the above situation destroys the best internal and external characteristics of the gasoline engine.

[0002] In the current prior art, there are many types of synthetic fuel oils utilizing alcohol hydrocarbons, such as methanol gasoline in various proportions, but there are common defects: one, methanol is hydrophilic, and methanol gasoline is separated from water. Generally, existing products only It can control the encounter of 0.5%-1% water without phase separation, and the water is dispersed in the mother liquor in a microemulsified state

In addition, since the calorific value of methanol is only half of that of gasoline, and the gasoline mixture requires an increase in calorific value, the above situation destroys the best internal and external characteristics of the gasoline engine.

Second, the temperature of the application environment will affect the phase separation. Generally, the product is controlled to -25°C without phase separation, which is not suitable for northern regions in winter.

[0003] In addition, although the vapor pressure of methanol is lower than that of gasoline, its temperature-pressure curve is very steep. As the temperature rises, its vapor pressure will rise sharply, which will easily lead to "gas blockage" in automobile oil pipelines, especially in sunshine. Long, high temperature and high altitude, low air pressure area
