Abstract: In this study, the production, performance and emission characteristics of biodiesel blends produced from bitter ground nut oil were compared to the diesel fuel. In first part of research, the production of biodiesel from bitter groundnut oil and optimisation of process parameters were undertaken. In second part, performance of 4-cylinder Tata Indica diesel engine has been studied at different engine speeds. During engine performance tests, the biodiesel blends showed higher brake specific fuel consumption and exhaust gas temperature, while marginally lower brake power, torque and brake thermal efficiency than the diesel fuel were noticed. Engine emissions showed higher carbon dioxide and nitrogen oxide releases, but decreased amount of carbon monoxide for biodiesel blends compared to the diesel fuel. From the experimental results, it is clear that the bitter groundnut oil-based biodiesel can also be used in a CI engine without any modifications.
