Comparative assessment of butanol and algae oil as alternate fuel for SI engines

The main objective of this paper is to investigate the potential of butanol and algae oil as alternate fuels for SI Engines using blends of gasoline-butanol and gasoline-algae oil. The studies have been carried out on the effect on IC engines under different volume basis of butanol-gasoline blends. The effect of Butanol and Algae addition on combustion of SI engine by considering parameters such as variable compression ratio, algae and butanol blend ratio and loading conditions have been studied. As butanol content in fuel is increased, the efficient combustion process will take place. Further, as the load is increased, the heat release becomes higher in case of pure gasoline, pure diesel and their respective blends with butanol. Also, the different performance parameters like power, emissions, and economy of fuel have been studied. The studies reveal that the power, torque, brake specific energy consumption, Hydrocarbons, Carbon-mono-oxides and NO emissions gets improved with butanol addition, whereas NOx and CO2 emissions are higher than gasoline and diesel. Algae fuel has shown enhancement in the brake specific fuel consumption, NOX, CO emissions and reduced in brake thermal efficiency. (C) 2019 Karabuk University. Publishing services by Elsevier B.V.
