Problems solved by technology

[0015] Based on the above analysis, it is not difficult to find that there is a common technical obstacle among the above-mentioned status quo, that is, no matter whether methanol fuel or ethanol fuel is used, ordinary automobile engines cannot normally use alcohol (methanol or ethanol or a mixture of the two) without any modification. 20-70% of this kind of large proportion of compound alcohols clean fuels, leading to a large number of substitution of petroleum and the good wishes of reducing automobile exhaust pollution cannot be realized
Because with the continuous increase of the alcohol content in the fuel, the inherent defects of alcohols (such as hydrophilicity, low calorific value, strong penetration, etc.) are gradually exposed. If such a large proportion of alcohol fuel is simply prepared without improving the formula, It will inevitably face eight major problems such as water stratification, cold start difficulty, high temperature air resistance, insufficient power, increased fuel consumption, high temperature lubrication, metal corrosion and rubber swelling.

Abstract

The present invention discloses a vehicle mixed alcohol hydrocarbon clean fuel and its production method. Said fuel composition includes (by volume %) 20-70% of alcohol or mixed alcohol, 0.1-2% of alcohol active additive, 20-70% of raw material and 0-10% of low-carbon paraffin hydroarbon. Its production method is simple, the above-mentioned all raw materials are mixed so as to obtain the invented clean fuel.

Description

technical field [0001] The invention belongs to the field of liquid alcohol-containing hydrocarbon mixed fuel, in particular relates to an alcohol-hydrocarbon clean fuel for vehicles, and also relates to a production method of the fuel. technical background [0002] Since the 1970s in my country, methanol (Methanol CH 4 O) research on fuel, National Science and Technology Commission has just carried out in Shanxi during the "six five-year plan" blending 15% methyl alcohol (being M15 methanol gasoline, M represents methyl alcohol, and the figure behind M represents this alcohol content percentage in the fuel, Ethanol analogy, the same below) research and demonstration work. German Volkswagen is the first foreign car company to introduce methanol fuel engine technology to China. It has conducted international technical cooperation research with my country on 100% methanol (ie M100 methanol fuel) vehicles (dedicated methanol engines) for seven years. Table 1 is In the 1970s, s...
