The invention relates to an oil-saving additive of
fuel oil, which comprises the following ingredients in parts by weight: 0.2 to 0.7 part of biological
lipase, 6 to 9 parts of
sodium hydroxide, 3 to 7 parts of
xylenol, 1 to 3 parts of
sorbitan, 1 to 5 parts of carbinol, 1 to 5 parts of
fatty alcohol-
polyoxyethylene ether, 0.05 to 0.09 part of
tertiary butyl
ferrocene, 1 to 5 parts of methyl ethyl
ketone, 5 to 7 parts of high-grade lubricating
grease, 1 to 4 parts of quadrol, 0.003 to 0.009 part of 2, 6-Di-tert-butyl-methyl
phenol and 3 to 7 parts of
amyl nitrate, wherein the biological
lipase is used as a catalyst, the
fatty alcohol-
polyoxyethylene ether is used as a surface
active agent, the 2, 6-Di-tert-butyl-methyl
phenol is used as an
antioxidant, the quadrol is used as a decarbonizer, the high-grade lubricating
grease is used as a lubricating agent, the
tertiary butyl
ferrocene is used as a
smoke suppressor, the
sodium hydroxide, the
xylenol, the
sorbitan and the carbinol are used as an emulsifier, the methyl ethyl
ketone is used as a
cleaning agent, and the
amyl nitrate is used as an improving agent. The oil saving rate can reach more than 13.4 percent, the exhaust amount of harmful gas in
tail gas reaches more than 30 percent, the
noise is reduced by more than 14 percent, in addition, the accumulated carbon in an engine can be effectively cleared, and the
motive power can be obviously improved.
