Abstract
|
Authors
describe development of various physicochemical properties using multiple
alcohols (C2 to C6) at various ratios compared to that of the conventional
ethanol–gasoline blend. To optimize the properties of multiple
alcohol–gasoline blends, properties of each fuel were measured. Microsoft
Excel “Solver” was used to determine the optimum blend. Three blend ratios
were selected which possessed maximum heating value (MaxH), maximum research
octane number (MaxR) and maximum petroleum displacement (MaxD).
The blends were used for testing in a four cylinder gasoline engine at the wide open throttle condition with a variety of speeds. Outcomes were compared with that of E15 and gasoline. Optimized blends displayed higher brake torque and brake thermal efficiency (BTE), but lower brake specific fuel consumption (BSFC) than E15. NOx emission of optimized blends was higher than gasoline. However, MaxR, MaxD, MaxH reduced 4%, 14.57% and 20.76% NOx than that of E15. |
