Abstract
A study was carried out to assess the advantages of incorporating nanoparticles, such as aluminum oxide and cerium oxide, into tamarind biodiesel blends to improve engine efficiency and reduce emissions. Different fuel blends were prepared by mixing aluminum oxide, cerium oxide, diesel, and biodiesel. Nanoparticles of aluminum oxide and cerium oxide, each at a concentration of 25 ppm, were added to diesel and tamarind biodiesel blends. The experiments were performed using a water-cooled, single-cylinder diesel engine with a power output of 4.4 kW. The results demonstrated a 2% reduction in brake-specific energy consumption with the addition of nanoparticles to the B20 fuel blend. Furthermore, the inclusion of both nanoparticles in the B20 fuel blend improved engine performance and emissions. Compared to standard B20 fuel, hydrocarbon emissions were reduced by 3.8%–11.5%, smoke emissions by 1.1%–6.9%, nitrogen oxide emissions by 2.5%–7.5%, and carbon monoxide emissions by 25%
