The invention discloses a nonmetallic
gasoline additive and a method for preparing the same. The nonmetallic
gasoline additive comprises, by weight, 0.5-12% of polyether, 0.5-12% of polyether
polyol,0.5-10% of poly-
alcohol, 0.1-15% of catalysts, 0.1-15% of stabilizers, 1-16% of soluble
silicic acid and 55.9-92% of
polyol. The method includes adding the polyether, the polyether
polyol, the poly-
alcohol and the catalysts into the polyol; carrying out stirring reaction to obtain transparent oily liquid; adding the soluble
silicic acid into the liquid; carrying out stirring reaction at the temperature of 80-110 DEG C until solution turns clear; filtering the clear solution to obtain the nonmetallic
gasoline additive. The nonmetallic gasoline additive and the method have the advantages that more than 18% of gasoline can be saved by the aid of the nonmetallic gasoline additive under identical conditions, emission of
hydrocarbon HC,
carbon monoxide CO, PM (particulate matters) and
nitrogen oxide NOx can be reduced to a great extent, the
smoke intensity can be lowered to a great extent, and effects of inhibiting
carbon deposit generation and eliminating carbon deposits can be realized; the nonmetallic gasoline additive is stable in property, can be safely stored and transported and is free of damage to gasoline cylinders and engines, the nonmetallic gasoline additive and gasoline arecompletely mutually soluble,
precipitation and layering can be prevented.
