Influence of iron oxide nanoparticles with different injection pressures using lotus seed methyl ester biodiesel: an experimental investigation

ABSTRACT

The present research work explores the utilization of lotus seed methyl ester in a Common rail direct injection diesel engine. It evaluates the performance, combustion aspects, emission features at different injection pressures 210 bar to 240 bar intervals of 10 bar, along with 120 ppm of iron oxide nanoparticle. For this investigation, the B20 blend used as fuel contains 80% diesel and 20% biodiesel (Lotus seed Methyl Ester). The iron oxide nanoparticles were mixed with the fuel using a mechanical homogenizer and ultrasonication. The present work results revealed a reduction in FC by 12.5%, decreased CO by 50%, a decrease in HC by 16.88%, and the reduction of smoke density by 16.51% compared to that of baseline fuel maximum load (5.2 kW). The combined effect of 240 bar injection pressure and 120 ppm of iron oxide nanoparticle gives the best result.
