Abstract

The first results of a study of the molecular structure of carbon in diesel particulate matter (DPM) by scanning transmission X-ray microspectroscopy were presented. Conventional diesel was combusted in a test engine, and the soot particles were collected on a filter following the exhauster. Aromatic and aliphatic groups could be discriminated and localized in single DPM particles, and unburned fuel and oil from solid soot could be distinguished. The carbonaceous soot particles were very likely porous aggregates and loaded with residual fuel and lubricant. Immersed in acetone and then poured on a sample slide, a corona could be found around the particles.
