Optimization of biodiesel percentage in fuel mixture and engine operating conditions for diesel engine performance and emission characteristics by Artificial Bees Colony Algorithm

Recently, biofuels mostly oxygenated diesel fuels are receiving more attention to use in diesel engines due to fossil fuels depletion and the environmental degradation. The objective of this research is using Artificial Bees Colony Algorithm approach to optimize engine performance and emission characteristics by determine optimize condition of biodiesel percentage in fuel mixture (biodiesel and diesel fuel No. 2), engine speed and engine load. The results of optimization showed that amount of biodiesel percentage, engine speed and load were 85.63%, 2208 rpm, 97% respectively. At the optimum point, the values of power, torque, BSFC, CO, HC and NOx were obtained equal to 63 kW, 298 N·m, 202.85 g/kW·h, 0.012%, 88 ppm and 560 ppm respectively. This finding proves that ABC algorithm can estimate the optimum point in engine performance with high accuracy.
