- Abstract
The current work focuses on experimental studies using Mesua Ferrea biodiesel (BD20) and Cr2O3 nanoparticles in a diesel engine. In different concentrations, 60, 80, and 100 mg/L Cr2O3 nanoparticles were mixed. In addition, the dispersant (QPAN80) and surfactant (CTAB) were used to change the surface of the Cr2O3 nanoparticle (at a 1:1 ratio). The compression ratios were varied such as; 16.5:1, 17.5:1, and 18.5:1, respectively. Using a mechanical agitator and a probe sonicator, the nanofuel was produced by inserting the surface modified Cr2O3 nanoparticles into BD20. The combustion characteristics of nanoparticles added to BD20, such as cylinder pressure (CP) and net heat release rate (NHRR) have improved greatly over normal diesel. However, nanofuels improved performance in terms of brake specific fuel consumption (BSFC) and brake thermal efficiency (BTE). Together with NOx, the emission characteristics (CO, UHC, and smoke) were reduced momentously. Eventually, a good trend in performance, combustion, and emissions were seen as the compression ratio increased. The dispersant added nanoparticles in BD20 has shown good outcomes than the surfactant added nanoparticles and base nanoparticles. The BD20 + Cr2O3 80 mg/L + DSP 80 mg/L had the best results of all the test samples. At CR 18.5:1, the BTE, BSFC, CP, and NHRR were 34.52%, 0.342 kg/kWh, 65.52 bar, and 88.79 J/oCA, respectively, whereas CO, UHC, smoke opacity, and NOx were, 0.092%, 35 ppm, 20.26%, and 1249 ppm, respectively.
