Influence of Aluminum Oxide Al2O3 Nano Particles Blended with Waste Cooking Oil in the Performance, Emission and Combustion Characteristics on a DI Diesel Engine

摘要

An experimental investigation is carried out to establish the performance and emission characteristics using Aluminum oxide (Al2O3) as nano additive in WCO blended with various proportions of nano additives 25ppm, 50ppm and 75ppm respectively. The biodiesel is produced from the WCO by standard transesterification process and subsequently, the nano particles are blended by means of an ultrasonicator to achieve stable suspension. It is observed that the blends are stable which are suitable for the performance test on the compression ignition engine. The characterization study of the nano particles such as SEM is carried out to analyze their morphology. The whole investigation is carried out in a single cylinder DI diesel engine using different proportions of nano additive blended biodiesel. The result shows a considerable enhancement in brake thermal efficiency and specific fuel consumption due to the influence of aluminium oxide nanoparticles addition in biodiesel blend.
