Gasoline Fuel Economy Improvement by Using Bio-Additive

A kind of bio-additive extracted up from tropic plant is used to improve gasoline burning efficiency.The bioadditive was added into four kinds of commercially used gasoline with octane number of 93,which are super-clean gasoline,prime gasoline,prime gasoline with known components and ethanol-gasoline.Through engine bench testing,fuel economy with and without the bio-additives were compared and analyzed.The results showed that when engine operating on the fuels with the bio-additive,engine fuel economy could be improved remarkably,the effect is particularly obvious for ethanol-gasoline.Engine fuel economy with addition of bio-additives can reach the same level as that of using prime gasoline.
