The aim of this study was to investigate the effect of magnetic flux density (6000 Gauss) on diesel engine fuel consumption and emissions. Experiments were performed at different distances with respect to the magnet in the fuel line (20, 40 and 60 cm) and at different engine speeds (1800, 2100, 2400 and 2700 rpm). We then selected carbon monoxide (CO), unburned hydrocarbons (UHC), carbon dioxide (CO2), nitrogen oxide (NOX) and fuel consumption as our study traits. According to the findings, the levels combination of 1800 rpm and 40 cm resulted in the greatest reduction of carbon monoxide, which was declined by 67 % compared to the control sample. The least amount of unburned hydrocarbon was observed at 1800 speed and 40 cm distance from the magnet with a value of 131.33. Moreover, the highest amount of nitrogen oxide was found in the 1800-20, 1800-40, 2100-40 levels compounds with 62, 59, 57 and 56 ppm, respectively. Fuel consumption was 3.023, 3.23, and 3.25 (Lit/h) at the maximum engine speed and distances of 20, 40, and 60 cm from the magnet, correspondingly; and dropped by 12, 6.1, and 5.52% compared to the control sample. We recruited response surface methodology to optimize process conditions. Based on the results, the optimal conditions were obtained at 1800 rpm and a distance of 37 cm of magnet on the fuel line. Under these optimal conditions, the amount of carbon monoxide, unburned hydrocarbons, carbon dioxide, nitrogen oxide and fuel consumption were 0.49%V, 128.45 ppm, 1.96%V, 61.3 ppm, and 1.92 (Lit/h) with desirability of 0.7, respectively.
