In this study, the usability of the boron oxide (B2 O3) nanoparticles as diesel fuel additive was experimentally investigated. Boron oxide nanoparticles were added to the diesel-biodiesel blend (B20) containing 20% by volume canola oil biodiesel at 50 ppm, 100 ppm, and 200 ppm concentrations by mechanical and ultrasonic mixing techniques. Some fuel properties of the prepared nano fuels were measured and then engine tests were carried out at standard engine settings. In these tests, the effect of boron oxide nanoparticles on combustion, performance, and emissions characteristics of the diesel engine were investigated. In addition, a cost analysis was carried out depending on fuel price and specific fuel consumption. According to the results obtained, it was determined that boron oxide nanoparticles improve the cold flow properties of the fuel but increase the kinematic viscosity. It has been determined that boron oxide nanoparticles can be used at a concentration of 100 ppm in terms of high engine performance. It was ascertained that the specific fuel consumption of the engine decreased by 1.66% and the effective efficiency increased by 0.96% at this nanoparticle concentration. At the same time, CO and HC emissions decreased on average by 1.29% and 22.12%, respectively. But under the same engine operating conditions, NO and soot emissions increased by 14.90% and 31.03% on average. Though, the decrease in specific fuel consumption, the fuel cost per unit of effective power increased by 116% on average due to the high price of nanoparticles. Once all findings are evaluated, it has been concluded that boron oxide nanoparticles can be used as nanofuel additives for diesel-biodiesel fuel mixtures if the benefit-cost balance is achieved.
