| Abstract | ||||
| In this study, jatropha biodiesel fuel blends were used by volumetric ratios of 20%, 40%, 60%, 80% and 100% with Diesel fuel to evaluate Diesel engine performance. Jatropha oil was extracted from jatropha carcass and converted to biodiesel fuel using transesterification reaction. Tests were performed on a four stroke, two cylinder, direct injection, air cooled Diesel engine at full load and different speeds, namely 500, 750, 1000.1250 and 1500 rpm. The present study reveals that, locally jatropha biodiesel fuel can be used as an alternative fuel for Diesel engines without any modifications. However, there was a decrease in engine performance with increasing biodiesel fuel percentage in the blends. The results showed a decrease in both of brake power by 16%, brake thermal efficiency by 22%, air to fuel ratio by 17% (which indicates that the consumption of air is less in case of biodiesel fuel blends compared to Diesel fuel), volumetric efficiency by11%. While there are increases in brake specific fuel consumption by 31% and exhaust gas temperature by 34% compared to Diesel fuel. | ||||
