Morphology, structure and chemistry of extracted diesel soot—Part I: Transmission electron microscopy, Raman spectroscopy, X-ray photoelectron spectroscopy and synchrotron X-ray diffraction study
چکیده انگلیسی

Inclusion of soot in lubricating oil can result in increased wear and decreased lubricity. In this study we have attempted to gain fundamental insight into the morphology, structure and chemistry of diesel soot. Energy dispersive spectroscopy using TEM suggests interaction between lubrication additives and crankcase soot resulting in the presence of C, Ca, S, P, O and Zn. Synchrotron X-ray diffraction indicates the presence of different sulfates of calcium as well as the presence of amorphous zinc based compounds. Raman spectroscopy and selected area diffraction using TEM indicates that the turbostratic structures of the carbon in both are very similar.


► This study examines the structure and properties of soot extracted from a EGR engine.
► Synchrotron X-ray diffraction was used study the crystalline and amorphous constituents of diesel soot.
► Raman spectroscopy coupled with TEM was used to examine the structure of diesel soot.
► This is the first comprehensive study of EGR soot published in the literature.
