Bio-ethanol Fuel Study on Spray Characterization Using High Speed Digital Camera

Fuel spray characteristic is very important in the entire internal combustion engine.
Today, researchers try to improve on the fuel which will produce less emission and also
improve the fuel consumption. Some of the new type of fuel is introduced such as the
ethanol which mainly extract from the crop. By introducing an alternative for the
gasoline, we mainly want to be fewer dependants for the fossil fuel which will be
depleted. So a study will be conducted to see the spray characteristic of these new fuels.
The fuel that wants to be studied is bio-ethanol, which are ElO and E85. Bio-ethanol has
been identified as the possible future fuel. This project is looking for the development of
bio-ethanol. Baseline characterization of the spray pattern is required prior to advance
studies in spray-guided direct injection process. By using the ethanol, we can produce
cleaner combustion with lower emissions which is very important aspect in today's
world. This study is mainly to compare the characteristic of neat gasoline and the
ethanol-gasoline blend which is El 0 and E85 in term of their spray tip penetration length
and the spray tip velocity.
