AN EFFECT OF COBALT OXIDE NANO ADDITIVE WITH BIODIESEL BLENDS USING CIDI DIESEL ENGINE

Major research is focused on fuel consumption and emission reduction in the past years. There is growing interest on alternative fuels due to volatile fossil fuel price and depletion. Utilization of transition metal additive in nanocrystalline form helps the combustion in molecular level and also reduces emissions and fuel consumption values. To forms a stable nano fluid metal oxide additive is added to biodiesel and ultrasonicated. The single cylinder, air cooled, and constant speed kirloskar engine is chosen for experimental study. The performance studies indicated the increase in thermal efficiency of 1% because the better mixing resulting secondary atomization and disruption of primary droplet containing additive and burns completely. Nearly 60% emission reduction was observed for 100% biodiesel at full load.
