AB  - The current work includes a numerical investigation of the effect of biodiesel blends with different aluminum oxide nanoparticle concentrations on the combustion process in the cylinder of a diesel engine. IC Engine Fluent, a specialist computational tool in the ANSYS software, was used to simulate internal combustion engine dynamics and combustion processes. Numerical analysis was carried out using biodiesel blends with three Al<sub>2</sub>O<sub>3</sub> nanoparticles in 50, 100, and 150 ppm concentrations. The tested samples are called D100, B20, B20A50, B20A100, and B20A150 accordingly. The modeling runs were carried out at various engine loads of 0, 100, and 200 Nm at a rated speed of 1800 rpm. The combustion characteristics are improved due to the catalytic effect and higher surface area of nano additives. The results showed the improvements in the combustion process as the result of nanoparticle addition, which led to the higher peak cylinder pressure. The increases in the peak cylinder pressures for B20A50, B20A100, and B20A150 about B20 were 3%, 5%, and 8%, respectively, at load 200 Nm. The simulation found that the maximum temperature for biodiesel blends diesel was higher than pure diesel; this was due to higher hydrocarbon values of B20. Also, nano-additives caused a decrease in temperatures in the combustion of biofuels.
