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 (E0) and gasoline-ethanol (gasohol) fuel (E10) in a direct injection gasoline injector in a gasoline engine. Two different fuel which is gasoline fuel (E0) and gasoline-ethanol (gasohol) fuel (E10) 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 (E0) shows that longer penetration, ethanol show the lower penetration and E10 is more closed to gasoline characteristic, it is because fraction of E10 is more to gasoline (E0) other than ethanol. So that the higher ethanol fraction in gasoline blends produce lower spray tip penetration and larger cone angle.
