Abstract: The increased attention on alternative fuels in the recent years was mainly driven by increasing oil prices, strong emission norms and the concern on clean environment. The biodiesel has emerged as a potential substitute for diesel fuel on the amount of its renewable source and lesser emissions. In order to increase the swirl in the combustion chamber, we are redesigning the piston crown with elliptical shaped grooves over it. The present research is aimed to investigate experimentally the performance and exhaust emission characteristics of a direct injection compression ignition engine equipped with a redesigned piston crown fuelled with conventional diesel fuel, blend of diesel and rice bran oil biodiesel, and blends of diesel and rice bran oil biodiesel with varying proportions of zinc oxide nano materials as additives over the entire range of load on the engine. The piston in the diesel engine is replaced and then fuelled with the above said fuels. The performance parameters such as brake power, specific fuel consumption, thermal efficiencies are calculated based on the experimental analysis and engine emissions such as CO, HC, CO2 , and NOx emissions are measured. The data has been analyzed and the results are presented and discussed in this project.
