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

The research evaluates the impact of Sargassum algae methyl ester (SAME20) with 50 and 100 ppm silicon dioxide (SiO 2 ) nanoparticles on performance emissions a single-cylinder, four-stroke diesel engine. SiO were characterized using FTIR, SEM, TEM. Diesel, SAME20, SAME20 + , blends tested at 1500 rpm under loads from 25% to 100%. blend outperformed others, improving brake thermal efficiency by 1.43% reducing brake-specific fuel consumption 5.35% compared diesel. It also decreased HC, CO, smoke 11.12%, 18.1%, 16.2%, respectively, slight NO x increase. Tribological analysis four-ball tribometer showed reduced coefficient friction 76.89% wear scar diameter 59.19%. SEM confirmed surface damage, highlighting improved engine tribological performance.
