Abstract:
The aim of this study was to investigate the effect ofmagnetic flux density (۶۰۰۰ Gauss) on diesel enginefuel consumption and emissions. Experiments wereperformed at different distances with respect to themagnet in the fuel line (۲۰, ۴۰ and ۶۰ cm) and atdifferent engine speeds (۱۸۰۰, ۲۱۰۰, ۲۴۰۰ and ۲۷۰۰rpm). We then selected carbon monoxide (CO),unburned hydrocarbons (UHC), carbon dioxide(CO۲), nitrogen oxide (NOX) and fuel consumptionas our study traits. According to the findings, thelevels combination of ۱۸۰۰ rpm and ۴۰ cm resultedin the greatest reduction of carbon monoxide, whichwas declined by ۶۷ % compared to the controlsample. The least amount of unburned hydrocarbonwas observed at ۱۸۰۰ speed and ۴۰ cm distancefrom the magnet with a value of ۱۳۱.۳۳. Moreover,the highest amount of nitrogen oxide was found inthe ۱۸۰۰-۲۰, ۱۸۰۰-۴۰, ۲۱۰۰-۴۰ levels compoundswith ۶۲, ۵۹, ۵۷ and ۵۶ ppm, respectively. Fuelconsumption was ۳.۰۲۳, ۳.۲۳, and ۳.۲۵ (Lit/h) atthe maximum engine speed and distances of ۲۰, ۴۰,and ۶۰ cm from the magnet, correspondingly; anddropped by ۱۲, ۶.۱, and ۵.۵۲% compared to thecontrol sample. We recruited response surfacemethodology to optimize process conditions. Basedon the results, the optimal conditions were obtainedat ۱۸۰۰ rpm and a distance of ۳۷ cm of magnet onthe fuel line. Under these optimal conditions, theamount of carbon monoxide, unburned hydrocarbons, carbon dioxide, nitrogen oxide and fuelconsumption were ۰.۴۹%V, ۱۲۸.۴۵ ppm, ۱.۹۶%V,۶۱.۳ ppm, and ۱.۹۲ (Lit/h) with desirability of ۰.۷,respectively.
