Experimental Test and Optimization of Energy Additive for Combustible Fuels to Lower Pollutant Gases

Environmental concerns, economic growth, and population growth are all contributing to the continuous rise in demand for renewable energy. DXP fuels can be synthesized from renewable resources, aligning with global efforts to reduce dependence on non-renewable energy sources and lower the carbon footprint. The DXP fuel was blended with diesel in three different proportions, and these DXP-diesel blends were tested on a 638 cc diesel engine. On average, it was found that the Brake thermal efficiency (BTE) for 2LDiesel + 1ML DXP and 3LDiesel + 1ML DXP decreased by 10.85 and 9.01% compared to diesel. However, the average BTE for 1LDiesel + 1ML DXP increased by 1.62% compared to diesel. On average, the 2LDiesel + 1ML DXP and 3LDiesel + 1ML DXP demonstrated a remarkable drop in CO2 emissions of 2.81 and 2.28%, respectively, in comparison with diesel fuel. However, the CO2 emissions for 1LDiesel + 1ML DXP increased by 0.53% in comparison with diesel. In contrast to diesel fuel, 1LDiesel + 1ML DXP, 2LDiesel + 1ML DXP, and 3LDiesel + 1ML DXP showed an average NO emission reduction of 1.37, 2.74, and 0.80%, respectively. In summary, hydrophilic DXP fuels as alternative fuel additives offer significant engine performance, emission reduction, fuel stability, and environmental sustainability.
