The type of process that needs to be done to produce biodiesel is called “Transesterification”. In the present study, the transesterification process has been done to obtain the biodiesel from three different vegetable oils (soya bean oil, palm oil and rice bran oil) and the performance of three such biodiesel fuels blended with Diesel in different composition has been investigated on single cylinder diesel engine. This study is also includes the performance comparison among the blended fuel and the conventional fuel (diesel alone) on the same single cylinder diesel engine based on the different performance parameters. Finally we concluded that the blended fuel having the better performance than Diesel in different aspects.

INTRODUCTION Bio-fuel is liquid fuel produced from plant origin .It can either be Biodiesel or ethanol. Liquid fuels from plant origin. Biodiesel is Diesel obtained from organic oils, mostly vegetables oils. Biodiesel is produced by modifying vegetable oils and reducing their viscosity by various methods. Ethanol is produced from sugar and starch. The energy challenge is especially acute in the transport sector, as most vehicles will continue to rely on liquid fuels for the decennia to come. Diesel and petrol (gasoline), obtained from fossil oil, will gradually be replaced by renewable liquid fuels, which are called bio-fuels. The most important among them are pure plant oil, Biodiesel (Diesel derived from PPO) and ethanol made from starch or sugar. The crops that are used for bio-fuel production are called energy crops; these include palm, soya bean, rice bran, olive oil , panama , sunflower , coconut , Jatropha , peanut , gingelly etc for biodiesel production and sugar cane, sweet sorghum, cassava, etc for ethanol production. In this study we analyzed the performance of different bio-fuels from soya bean, palm oil and rice bran oil on the single cylinder water cooled Diesel engine; also we compared the results obtained from these fuels with the results of conventional fuel (Diesel). Finally we concluded that the bio fuels having better performance than Diesel in different aspects. 2.
