A diesel engine was fuelled with diesel and karanja biodiesel blends and its performance and emission characteristics studied. The parameters such as specific fuel consumption (SFC), brake thermal ef ficiency (BTE) and exhaust emissions of carbon dioxide (CO2), carbon monoxide (CO),and oxides of nitrogen(NOx) were measured and compared with diesel fuel. With 100% karanja (Pongamia pinnata) biodiesel, the specific fuel consumption was 340, 304 and 287 g/kWh at 1.5, 2.0 and 2.5kW load conditions while for diesel it is found that 318,287 and 260 g/kWh at 1.5.2.0 and 2.5kW load condition The per cent increase in brake thermal efficiency of engine with karanja biodiesel blends (B15 to B60) ranged from 0.1.1 to 2.3% higher than diesel fuel. . The CO2emission from 100 %biodiesel was slightly higher than that of diesel. The CO reduction and increase in NOx emission by biodiesel were 15to 17 % and 19 to 29 % respectively as compared to diesel at tested load conditions Keywords: Pongamia pinnata, biodiesel, karanja and Fossil fuels
