Use of biodiesel or vegetable oil in IC engine has been tried by many researchers. It has been found that the best efficiency is obtained with 20% blend of biodiesel in biodiesel-diesel combination. However in order to obtain complete benefit of biodiesel use, the engine should be made to work on higher percentage of biodiesel or solely on biodiesel. The authors speculate that such a scenario can be arrived at by making certain modification in the engine. In this work an attempt has been made to see if changing the injection nozzle configuration could result in the use of higher percentage of biodiesel in the blends with comparable efficiency. 3, 4 and 5-hole nozzle configurations were tried. From the result it is found that for higher percentage blend of biodiesel (60% and 100%) 3-hole nozzle configuration found to be the best. However 5-hole nozzle resulted in better results than that of 4-hole nozzle configuration.
