Abstract / Synopsis

Biodiesel/diesel blends (BDB) were prepared using different biodiesel percentages (10, 15 and 20% v/v) namely B10, B15 and B20, respectively. A high energy emulsification method was employed for this purpose. An engine test bed was utilized to combust the emulsion in order to investigate emission gas concentrations such as CO, NOx, CO2, O2 and smoke. The emission concentrations of NOx and O2 were decreased with increasing biodiesel concentration. However, the emission of CO2 was increased with the increasing amounts of water. The highest concentration of NOx was found for B15. The physicochemical properties of BDB emulsion fuel in terms of viscosity and calorific value were also measured and investigated. Furthermore, biodiesel showed the highest viscosity compared to diesel and BDB fuels. The viscosity of BDB fuels was increased from B10 to B20. The increasing biodiesel concentration showed a decrease in calorific value. Hence, emulsified biodiesel fuel is a promising alternative fuel for reducing harmful emissions.
