PURPOSE: The titled fuel suitable for internal combustion engine, obtainable readily, reinforcing the deflagration properties of inexpensive alcohols, being substituted for petroleum resorces, obtained by adding nitrocellulose cotton to a solution of an alcohol, followed by blending.

CONSTITUTION: A given volume of nitrocellulose cotton (preferably fibrous or particulate state, the surroundings of the cotton are covered with a combustible film which is insoluble in an alcoholic solution) is added to a solution of alcohols (preferably, a reproducible material, e.g., starch, molasses, etc., synthetic alcohol, e.g., methanol, isopropyl alcohol, etc.), and blended to give a reinforced alcohol fuel. The pulverization and fine granulation of the nitrocellulose cotton itself make the covering treatment better, and the jetting of the mixed fuel to the cylinder and the ignition to the nitrocellulose cotton during combustion and deflagration more smooth, quick, and secure.

EFFECT: A small environmental pollution caused by exhaust gas.
