The major difficulty encountered with the use of methanol-gasoline blends a
s SI engine fuel is their tendency to phase separation due to the hydrophil
ic properties of methanol. Phase separation can lead to some utilization pr
oblems. Using a blending agent for the methanol-gasoline system is the comm
on approach taken towards solving the phase separation problem. In this stu
dy introduces fraction of molasses fusel oil as an effective new blending a
gent for methanol-gasoline fuel.
