Biofuels, which are widely used as alternative fuels to reduce fossil fuel consumption and replace them with fossil fuel-like energy sources, are increasingly being supplemented with nanoparticles (NP) to overcome their limitations, including lower energy content and higher emissions. The study aimed to examine the impact of Fe-Ni-TiO2/activated carbon (AC) nanoparticles, produced by the authors, on engine performance and emissions when added to diesel/biodiesel fuel blends. The produced Fe-Ni-TiO2/AC NP was employed as an additive in palm oil (PO)/diesel fuel blends at 50 and 100 ppm concentrations. The results revealed that compared to standard diesel, employing Fe-Ni-TiO2/AC NPs lowered emissions including smoke, carbon monoxide (CO), and hydrocarbon (HC) in all fuel blends while increasing nitrogen oxide (NOx). In the DNP30-100 fuel blend at 2500 W engine load, there was an increase in NOx by 8% and a decrease in CO, HC, and smoke emissions by 70.3%, 86.3%, and 57.5%, respectively, compared to standard diesel. Furthermore, a decrease of 11.38% was observed in brake-specific fuel consumption, while brake thermal efficiency increased by 16.59% compared to diesel. The overall results suggest that using Fe-Ni-TiO2/AC as an additive in a diesel-biodiesel fuel blend can improve engine performance and decrease emissions.eninfo:eu-repo/semantics/closedAccessNano fuelnanoparticlebiodieselfuel blenddieselArticle10.1080/17597269.2023.22218812-s2.0-851622081596717Q366114WOS:001011719500001Q3
