Investigation on effect of Mn and Ce metal additives on diesel fuel properties and emissions

Two metal base additives were selected from literature, Mn and Ce then we added 100 mg/kg of them into the diesel. The experimental study was carried out on ECE R-96 8-modes cycle. Fuel physical property such as density viscosity and cetane index were investigated for three kinds of fuels. Density and viscosity decreased for diesel with Ce and Mn. Cetane index for fuels with additives improved than sole diesel also the results from ECE R-96 8-modes cycle showed the brake specific fuel consumption (BSFC) did not change significantly except for diesel with Ce in ratedpower speed and low load condition. Fuels with additives emitted low soot levels and do not change values for NOx in compared with diesel significantly. By adding 100 mg/kg of Mn based additive into diesel fuel reduce BSSOOT and BSCO and low percent of CO2 at rated power speed condition. In general BSSOOT with Mn based additive reduced 25% lower than sole diesel.
