Alcohol group fuel for a cleaning vehicle is prepared from, by weight, 25-45% of arene, 25-69% of 
naphtha, 5-30% of 
denatured alcohol, 0.1-0.3% of stabilizer and 0.7-0.9% of fuel powerful agent in a 
mixed mode; the 
denatured alcohol is a mixed reactant of methyl 
alcohol, 
acetone, isopropanol  / 
isobutanol, 
dimethyl ether and 
sodium chloride; the stabilizer is a mixture of 
oleic acid, cyclic-propionic acid and 
diethylamine or 
propylamine; the powerful agent is a mixture of 
isoamyl nitrite and tetranitromethane. For the 
alcohol group fuel, a 
gasoline engine does not need to be modified, the power and the fuel consumption of the 
alcohol group fuel are equal to those of 
gasoline, the alcohol group fuel and the 
gasoline are soluble at any rate and the use quality is not affected; the alcohol group fuel has the advantages of being clean, capable of saving energy and capable of effectively reducing harmful gas emission in automobile 
tail gas by over 50%, wherein the emission of CO, HC and 
NOX is reduced by over 90%. The alcohol group fuel for the cleaning vehicle is simple in composition, wide in 
raw material source and low in production cost; 
water resistance is strong and 
combustion performance is good; the storage time is long, and the problems of layering and going bad are avoided; the alcohol group fuel for the cleaning vehicle is worth being produced in 
mass, popularized and used.
