Experimental Investigation of Operating Parameter Effect on DI CI Diesel Engine Using Flamboyant Biodiesel Blends

Due to the demeaning character of fossil fuels and their detrimental harmful effects on the ecosystem, studies have focused on finding appropriate non-edible replacements. In the present research, the emissions and performance features of the blends of biodiesel generated from the chosen raw materials (flamboyant seed), which includes B25, B50, B75, and B100, were evaluated in the early stages of the research. A diesel engine continues to operate at an authorized rate of 1500 rpm. In the following phase of the research, the focus is on defining the appropriate blend's performance as well as its emission characteristics under the ideal operating circumstances. The FME blend B25 is found to be satisfactory, and the optimal parameters to stated standards have been CR 18.5.With the exception of NOX emission, the ideal blend surpassed alternatives in terms of BSFC and BTHE associated with reduced CO and HC outputs. The optimum fuel's BSFC and BTHE at the maximum load, for CR 18.5, are 0.257 kg/kW-hr and 31.47%, respectively. The emission levels of CO, HC, and NO X are 0.08%, 51 ppm, and 1029 ppm.
