Biodiesel has been considered as potential alternative to petroleum diesel with the renewable origin for the existing compression ignition engine. The main objective of the present work is evaluating performance and emission characteristics of diesel engine for various blends (B20, B40, B60, B80 and B100) of Karanja biodiesel and commercial diesel. The experimental investigation was carried out in IC (internal combustion) at variable loads and compared with conventional diesel fuel with respect to engine performance parameters i.e. brake specific fuel consumption (BSFC), brake specific power consumption (BSEC), brake thermal efficiency (η-B.Th), for varying load conditions. The results obtained indicated the better fuel properties and engine performance at B40. For all cases, BSFC reduced with increase in load. It can be observed that the BSEC for various blends is lower as compared with that of diesel fuel. The availability of oxygen in the Karanja oil methyl ester-diesel fuel blend may be the reason for the lower BSEC. Brake thermal efficiency is increased due reduced heat loss with increased in load. It was found that the emission level of CO and HC level decreased with increased in blend proportion in diesel fuel. NO_x emission increased with increase in blend proportion in diesel fuel.
