Abstract

This research is about to characterize the spray of gasoline-ethanol (gasohol)
blends using optical measurement. The Image of the spray is captured using optical
measurement to extract spray characteristics- spray tip penetration and spray cone
angle. The focus of this study was to investigate the spray characteristics
performance of gasoline fuel (EO) and gasoline-ethanol (gasohol) fuel (E I 0) in a
direct injection gasoline injector in a gasoline engine. Two different fuel which is
gasoline fuel (EO) and gasoline-ethanol (gasohol) fuel (E I 0) blend rates by volume
are prepared. The Image of the spray is captured using imaging technique and image
processing is employed to extract spray characteristics of gasohol blends which is
spray tip penetration and spray cone angle. The experimental result is compared to
the theoretical result to see the actual result is similar to the theoretical or not. Digital
camera was used in order to observe the structure of fluids and to measure the spray
angles at nozzle exit. Based on the extracted tip penetration and cone angles Gasoline
(EO) shows that longer penetration, ethanol show the lower penetration and E I 0 is
more closed to gasoline characteristic, it is because fraction of E I 0 is more to
gasoline (EO) other than ethanol. So that the higher ethanol fraction in gasoline
blends produce lower spray tip penetration and larger cone angle.
