However, the complete adoption of biodiesel in CI engines is limited by several drawbacks. A promising solution to these problems is the addition of nanoparticles to biodiesel or diesel-biodiesel blends. Hence, this paper studies the impact of adding aluminum oxide (Al<sub>2</sub>O<sub>3</sub>) nanoparticles on the performance and emission characteristics of a diesel engine running on biodiesel and a mixture of diesel and biodiesel. Al<sub>2</sub>O<sub>3 </sub>nanoparticles were added at concentrations of 50, 100 and 150 ppm to biodiesel (B100) and a mixture of 50 % biodiesel and 50 % commercial diesel (B50). The results indicated an increase in fuel conversion efficiency and a reduction in specific fuel consumption. The highest fuel conversion efficiency was 26.5 % for B50 with 100 ppm of Al<sub>2</sub>O<sub>3</sub>, indicating an improvement of around 28.6 % compared to diesel fuel (B0). In general, CO emissions were reduced with the addition of nanoparticles, with a maximum reduction of 42.8 % for B100 with 50 ppm Al<sub>2</sub>O<sub>3</sub> compared to B0. The highest reduction in NO<sub>X</sub> emissions was 30.3 % for B50 with 100 ppm Al<sub>2</sub>O<sub>3</sub> compared to pure diesel B0.</p> Marcos Moresco Smaniotto Josimar Souza Rosa Giovani Dambros Telli Copyright (c) 2024 Marcos Moresco Smaniotto, Josimar Souza Rosa, Giovani Dambros Telli (Author) https://creativecommons.org/licenses/by/4.0 2024-03-04 2024-03-04 13 1 e241301 e241301 10.18226/23185279.e241301
