The Influence of Direct Non-Thermal Plasma Treatment on Soot Characteristics under Low Exhaust Gas Temperature

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 their impact on nitrogen oxides (NOx). The experiment involved maintaining constant flue flow rate 10 l/min, employing high voltage values 0, 6, kV, fixed frequency 500 Hz setting various IMEP 5, 7 bar engine speed at 2,000 rpm. findings demonstrated that NTP was successful removing NOx by approximately 16.84% 17.01%, achieving particle matter (PM) removal efficiencies around 60.79% 81.13%, effectively activation energy 18.34% 31.5% (with EGR, respectively) kV. These results highlight potential mitigating emissions environmental associated diesel engines.
