Abstract

2 Abstract: In this study, Jatropha biodiesel fuel blends are mixed by volumetric percentage of 20, 40, 70 and 100% with diesel fuel and burned in a diesel engine to study engine performance and emission. These tests were performed on a four stroke, single cylinder, water cooled diesel engine at different loads and rated speed of 1500 rpm. This research reveals that there is an increase in specific fuel consumption, exhaust temperature and air-fuel ratio in diesel- biodiesel blends (B20, B40, B70 and B100) than diesel fuel. The results show a decrease in thermal efficiency and volumetric efficiency for diesel-biodiesel than diesel fuel. The research exhibits a decrease in CO , CO and HC for diesel- biodiesel blend than diesel fuel. NO and O emissions 2 x2
