Mustard Oil Biodiesel Properties and Exhaust Gas Analysis on Kirloskar Diesel Engine

Our work is mainly focused on exhaust gas emission analysis, when Mustard oil based biodiesel (methyl esters) and fossil diesel fuel were tested in direct injection Kirloskar diesel engine. Exhaust gas characteristics and analysis of fuel injection was cleared by analysis of experimental data. When Kirloskar Engine fuelled with Mustard oil based biodiesel had increased brake specific fuel consumption (bsfc) , moderate increase in carbon monoxide emission (CO), decrease in nitrogen oxides emission(NOx).Fuel consumption increase due to lower calorific value of biodiesel . When we analysis of combustion characteristics, it will aware about the earlier start of injection and shorter ignition delay period of biodiesel. Due to the earlier start of injection and shorter ignition delay period of biodiesel, decrease in maximum rate of heat release and due to cylinder pressure was the most probable reason for reduced emission of nitrogen oxides (NOx). From the analysis of data it is found that cetane index is not a proper indication of ignition quality of Mustard biodiesel. Our work also show the renewable applicability of Mustard oil used as biodiesel. But our main concentration to analysis the emissions characteristics and combustion characteristics of biodiesel.
