The need of bio origin fuel is continuously increasing with depletion of petroleum fuel and rising concern of environmental degradation. Biodiesel is one of the bio origin fuel obtained from vegetable oil or animal fat in a process of trans-esterification. Many research have proved that biodiesel is a promising fuel in terms of performance of diesel engine and exhaust emission of CO2, CO, HC component..The only penalty with biodiesel is higher NOx emission with some exception. This research work focuses on the study of the engine working parameters i.e. engine fuel and speed of engine on NOx emissions with biodiesel as fuel in a diesel engine. The results shows that use of biodiesel and at high engine speed causes lower NOx emissions in comparison with conventional diesel fuel.
