PERFORMANCE AND EMISSION CHARACTERISTICS OF KARANJA (Pongamia pinnata) BIODIESEL AND ITS BLENDS IN A DIESEL ENGINE

Sriramajayam, S.

Abstract :

A 3.7 kW diesel engine was fuelled with diesel and karanja biodiesel blends and its performance and emission characteristics were studied. The parameters such as specific fuel consumption (SFC), ake thermal efficiency (BTE) and exhaust emissions of carbon dioxide (CO2), carbon monoxide (CO), oxides of nitrogen (NOx) and oxygen were measured and compared with diesel. With 100% biodiesel, the specific fuel consumption was 340, 304 and 287 g/kWh at 1.5, 2.0 and 2.5 kW load conditions. The per cent increase in ake thermal efficiency of engine with karanja biodiesel blends (B20 to B80) ranged from 0.94 to 5.83% higher than diesel fuel. The exhaust gas temperature increased with increase in loads and quantity of biodiesel in its blends. The CO2 emission from 100 % biodiesel was slightly higher than that of diesel. The CO reduction and increase in NOx emission by biodiesel were 15 to 17 % and 19 to 29 % respectively as compared to diesel at tested load conditions.
