【 摘 要 】

Biodiesel is an alternative and safe fuel to replace conventional petroleum diesel. With high-lubricity and clean-burning ability the biodiesel can be a better fuel component for use in existing diesel engines without any modifications. The aim of this Research was to study the potential use of Macro algae oil, Micro algae oil, Rice Bran oil methyl ester as a substitute for diesel fuel in diesel engine. B10 and B20 blends of these three types of fuels are prepared by transesterification process. The blends on volume basis were used to test them in a four stroke single cylinder diesel engine to study the performance and emission characteristics of these fuels and compared with neat diesel fuel. Also, the property testing of these biofuels were carried out. The biodiesel blends in this study substantially reduces the emission of unburnt hydro carbons and smoke opacity and increases the emission of NOx emission in exhaust gases. These biodiesel blends were consumed more by the engine during testing than Diesel and the brake thermal efficiency and volumetric efficiency for the blends was identical with the Diesel.
