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%

ABSTRACT This study investigates the performance and emission characteristics of a diesel engine running on blend Scenedesmus obliquus (SO) biodiesel, pyrolyzed waste plastic oil (WP), n‐heptane (H), acetylene induction (SOPWH), tested under various loads at 1500 rpm. The goal is to enhance brake thermal efficiency (BTE) reduce emissions in alignment with Sustainable Development Goals (SDGs) 7 11, which focus clean energy sustainable cities. SO biodiesel was produced via transesterification algae grown recycled wastewater, while WP obtained through pyrolysis 450°C. n‐Heptane added optimize blend, 4 liters per minute inducted into intake manifold. Results showed that SO5WP5H10 improved BTE by 0.93% no load reduced brake‐specific consumption (BSEC) 0.686 MJ/kW‐h part load, compared diesel. Emission reductions included 28% decrease hydrocarbon (HC) 35% reduction carbon monoxide (CO) full SO20WP20H10 blend. Smoke opacity decreased 19% maximum load. In terms combustion, achieved peak in‐cylinder pressure 77.5 bar an efficient mass fraction burnt (MFB), reaching 90% 25 o CA after TDC. Overall, SOPWH blends enhanced combustion cleaner emissions, positioning them as alternative diesel, without need for modifications. aligns global sustainability goals offering cleaner, more fuel option engines.
