For several years, ethanol is being used in controlled but unmarked fashion (levels less than 5%) in gasoline worldwide. Several problems associated with ethanol have put a restriction in using gasoline-ethanol blends with higher ethanol percentage, as it is in an existing engine. Changed physico-chemical properties of high ethanol percentage gasoline blend needs several challenges to be overcome in order to harness the potential of high ethanol content in the blend. The present paper highlights the results of investigation carried out with three different ethanol-gasoline blends i.e 10, 30 and 70 % ethanol blended with gasoline (E10, E30 and E70 respectively). An electronically controlled online fuel blending mechanism was designed and developed to ensure correct blending of two fuels in desired percentage.
