Performance Investigation of Compression Ignition (CI) Engine Using Biodiesel Mixtures

ABSTRACT Biodiesel, as asustainable and renewable fuel ancillary for diesel has been getting the attention of researchers all over the world. The research has indicated that upto B20, there is no need of any modification. The aim of the present paper is to evaluate the engine performance using pure biodiesel and its blends. Also blends of pure Jatrophacurcas oil with diesel and methanol is used in the present study to show their effect on engine performance in terms of brake specific fuel consumption (BSFC) and brake thermal efficiency (BTE). From the results it is found that brake specific fuel consumption for B100 was 14.8% higher than diesel. The brake thermal efficiency is found higher up to B30 in comparison to diesel while BTE of B100 (24%) was almost equals to diesel (24.5%) for Jatropha oil methyl ester (JOME)
