It can be confidently stated that there is limited research on the usability of nanoparticles as alternative fuel additives for diesel fuel (DF), particularly those produced from organic substances through the green synthesis method. On this basis, the present research focused on the usability of the fuels formed by adding metal-based titanium dioxide (TiO2) and silicon dioxide (SiO2) nanoparticles produced through green synthesis technique at different ratios to safflower oil biodiesel and commercial DF blends considering the thermodynamic, economic, and environmental analyses. In this sense, performance and emission tests were carried out in a single-cylinder diesel engine at four ranging loads (25 %, 50 %, 75 %, and 100 %) at a fixed speed of 1500 rpm. To conclude, the exergy efficiency enhanced as the load increased. Actually, for B10Si50 blend at 25 %, 50 %, 75 %, and 100 % loads, the exergy efficiency was calculated to be 16.46 %, 19.48 %, 21.08 %, and 21.95 %, respectively. As the amount of biodiesel infused to DF increased, the cost of losses went up gradually. In this context, the cost of losses for DF was calculated as 2.099 USD/h at the maximum engine load, meanwhile the cost of losses for B10 and B20 was figured out to be 2.326 USD/h and 2.487 USD/h, respectively. At the peak load, the ratio of the power taken from the engine shaft to the cost achieved for DF was 129.76 USD/GJ, while it was found to be 151.55 USD/GJ for B20. In addition, it was determined as 191.21 USD/GJ for B20Si250 fuel and 197.97 USD/GJ for B20Ti250. As stated in the exergoenviroeconomic analysis findings, the cost of monthly CO2 emissions ascended as the amount of nanoparticles augmented regardless of the type of fuel blends. At 75 % engine load, the cost of CO2 emissions for B20Si50 fuel was notified as 43.89 USD/month whereas it was found to be 47.74 USD/month for B20Si250.
