Abstract

In today's scenario lot of research work in India are undergoing for the suitable renewable fuels that are eco friendly. As an alternative, biodegradable, renewable, and sulphur free bio-diesel is receiving increasing attention. Use of nanoparticles are increasing around the world for making it imperative and to fully understand the impacts of nanoparticles in biodiesel on the C I Engine combustion phenomenon and pollutantion formation. Therefore, in this study performance test of CI engine are conducted for different curcas nut bio-diesel blends with nano particle and without nano particle was carried out. Biodiesel was made by well known Transesterification process. Curcas nut seed is chosen for biodiesel production. Cobalt oxide nano particle was produced by combustion synthesis process. The experiment is conducted for B10, B20 and B30 with 75mg Cobalt oxide nano particles and without nano particles. The engine experimental results of Curcas nut bio-diesel blend with nano particle showed that efficiency including thermal efficiency is 2% increased, and mechanical efficiency was reduced by 2% for biodiesel blend with nano particle. However, slight increase in specific fuel consumption was experienced for biodiesel mixture with nano particle. The cobalt oxide nano particle acts as an oxidizing catalyst and also provides oxygen for complete combustion of the blends.
