Arc generated Soot for a Comparison with Practical Diesel Soots using Characterization Analyses with a Time-lapse Regeneration Study on a DPF 2019-01-2289

This research aims to characterize an arc generated soot that was utilized as a surrogate for diesel engine generated soot. The two laboratory generated soots used in this study are arc generated soot and diesel fuel-lamp flame soot. In order to benchmark these surrogates with diesel engine soot, characterization was done by analyzing their oxidation behaviors, organic elemental composition, and nascent nanostructures. After that, the arc generated soot was utilized in a time-lapse DPF regeneration experiment to investigate its partial oxidation phenomenon using FE-SEM as a visualization tool. As a result, it was found that, by the appearance, arc-soot can be used as a diesel engine soot surrogate to study the shrinkage phenomenon of soot on a DPF substrate.
