摘要：Biodiesel is considering a clean-burning fuel produced from non edible vegetable oils, or animal fats. It is produced by transesterification of oils with short-chain alcohols or by the esterification of fatty acids. In the present context, biodiesel is an alternative eco friendly diesel fuel. Keeping this in view, an attempt has been made through the experiment of Thumba blended biodiesel on CI engine in laboratory and analyzes its properties and characteristic compare with other biodiesel oils. Five blends B05, B10, B15, B20 and B25 of thumba seed oil biodiesel were papered and it performance was evaluated with 7HP four-stroke diesel engine. The performance of thumba seed oil biodiesel were compared with biodiesel prepared by mustard, castor and Jatropha seed oil with same blends.
