Analysing emissions in compression ignition engines powered by diesel blend with bio diesel and nano particles

Year: 2025

Type: article

Abstract: This research involves both experimental and numerical studies that explore how different amounts of iron oxide nanoparticles (Fe₃O₄) in biodiesel blends influence combustion in a single cylinder diesel engine. To simulate the engine dynamics and combustion processes, Diesel Engine Fluent, a specialized numerical tool from ANSYS 19.0 software, was employed. Biodiesel blends were tested with three levels of Fe₃O₄ concentration: 50, 100, and 150 ppm. The samples used in these tests were labelled as D100, D80B20, D80B20N50, D80B20N100, and D80B20N150 (D80 stands for 80 % diesel, B20 for 20 % biodiesel, and N for nanoparticle). Various engine loads, ranging from 20 % to 90 %, were examined at speeds between 1100 and 2200 rpm. The presence of nano additives led to a reduction in emissions, attributed to their catalytic effects and enhanced surface area. The findings indicated that the addition of nanoparticles effectively lowered emissions. At a 90 % load, CO₂ emissions decreased by 3 %, 5 %, and 8 % for the D80B20, D80B20N50, D80B20N100, and D80B20N150 blends, respectively. Additionally, the presence of nano-additives also contributed to a decline in CO emissions from these blends. Furthermore, the combustion of the nanoparticle mixtures produced lower NOx emissions compared to the D80B20 blend.
