Abstract

This study aimed to assess the effectiveness of nonthermal plasma (NTP) technology utilizing a dielectric barrier discharge (DBD) reactor both with and without exhaust gas recirculation (EGR) in reducing soot particles and their impact on nitrogen oxides (NOx). The experiment involved maintaining a constant flue gas flow rate of 10 l/min employing high voltage values of 0 6 and 10 kV fixed frequency of 500 Hz and setting the various IMEP of 5 6 and 7 bar and the engine speed at 2 000 rpm. The findings demonstrated that NTP was successful in removing NOx by approximately 16.84% and 17.01% achieving particle matter (PM) removal efficiencies of around 60.79% and 81.13% and effectively reducing activation energy by approximately 18.34% and 31.5% (with and without EGR respectively) at a high voltage of 10 kV. These results highlight the potential of NTP technology in mitigating emissions and reducing the environmental impact associated with diesel engines. ? The Authors published by EDP Sciences.
