Paper Details

In recent years alternative fuels based on biomass are gaining more popularity as they have less emissionprofile. In this investigation experimental work is carried out to estimate the emission characteristics of a singlecylinder four stroke diesel engine running on Palm biodiesel blended with diesel. Engine tests have been carried out atconstant speed of 1500 rpm and compression ratio 18 using palm biodiesel and diesel with blends of D0, D50 and D100,where palm biodiesel is denoted by D0 and diesel is denoted by D100, at different loading conditions. This study alsotargets at finding the effects of supercharging and fuel injection pressure (IP) jointly on engine emissions of carbonmonoxide (CO), carbon dioxide (CO2), oxygen (O2), unburned hydrocarbons (HC) and oxides of nitrogen (NOx) withabove fuels. The results of experimental investigation with biodiesel blends with diesel are compared with that of diesel.The results indicated that the HC and NOx emissions are less for D0. NOx emission was found 30.17% lower forbiodiesel (D0) in comparison to diesel. It is found that with increase in injection pressure and with superchargingcondition palm biodiesel D0 have considerable lesser emissions of HC, O2, NOx as compared to D100. D100 has lowestCO emissions at all loading conditions than D0 for both normal and supercharging condition. Significant improvementin CO2 emissions has been observed for D100 in supercharging condition.
