This paper presents the performance and emission characteristics of a diesel engine fueled with biodiesel and diesel fuel. The tests were performed in a four stroke, single cylinder, naturally aspirated, air-cooled and direct injection diesel engine at the different engine speed under full-load conditions. The results obtained with biodiesel were compared with the diesel fuel as reference fuel. The engine torque and power obtained in biodiesel were less, and the specific fuel consumption was found to be higher, which could be attributed to lower calorific value of biodiesel. CO emissions for biodiesel were lower than that of diesel fuel. However, it was observed that NOx emissions for biodiesel were higher than that of diesel fuel.
