Effect of concentration of alumina nanoparticles on performance and emissions of biodiesel fueled compression ignition engine

Driven by the exacerbating urbanization and population, there has been a shoot up in the global energy demand over the past few years. The technological exploration efforts in the field of biofuels have proven to be a promising alternative to the slumping fossil reserves. The main aim of this work is to inspect the potential of palm oil as a biofuel with aluminum oxide nanoparticles as an additive in it. The experimental work was carried out on a single-cylinder four-stroke CI engine running at a constant speed of 1500 rpm at varying loads using palm oil biodiesel blends and the emissions and performance parameters were compared with that of neat diesel. The results concluded a significant increase in BTE with increase in alumina concentration in the blend owing to catalytic behavior of alumina which accelerates the combustion process. Furthermore, reductions in HC and CO emissions were also recorded.
