Popis: Fossil fuels are depleting faster than being consumed. Fuels with higher efficiency, less consumability, and ecocity are very much desired for the present scenario. In this investigation, a conventional single-cylinder CI engine is utilized in dual-fuel mode, in which biogas is the primary fuel while biodiesel (palm oil) with different DEE blending ratios is used (5%, 10%, and 15%) as a secondary fuel. For each DEE blend, biogas flow rate and loads are varied and their effect on brake thermal efficiency, pilot fuel energy ratio, CO, NOx, and HC emissions are estimated. Exhaust gas emissions were calculated using an AVL 5-gas emission analyser. The calorific value and density of each sample are calculated. It is witnessed from the experiments that 5% DEE used with lower biogas flow rate resulted in high brake thermal efficiency of 31.83%. Also, an increase in DEE is found to increase NOx emission while an increase in biogas flow rate resulted in a reduction in NOx emission. The addition of biogas is experimentally observed to have the potential in reducing pilot fuel consumption.
