Abstract

The present study is about the influence of non-thermal plasma (NTP) technology on soot emissions and physico-chemical properties (morphology, particle size, chemical composition and ignition temperature) of diesel PM. Experiments have been carried out using a small direct injection diesel engine with NTP technology based on a bench test. The physico-chemical properties of PM samples were detected by GC-MS, SEM, EDX, and TGA. PM samples after NTP treatment consisted of mainly hydrocarbons with less than 18 carbon atoms and few hydrocarbons with higher than 20 carbon atoms. Analysis by SEM and EDX showed that the agglomeration degree and the mean spherule diameters were markedly reduced by NTP oxidation. TGA showed that the ending combustion temperatures of PM samples in oxygen environment were 670.03 °C and 550.54 °C before and after NTP treatment, respectively. The mean temperature difference was nearly 120 °C, which indicated that NTP technology could effectively reduce the burning combustion temperature of diesel PM emissions.
