This paper describes the laboratory effort to relate quantities of diesel particulate volatile organics obtained by DFI/GC™ to those obtained by traditional methods of organic analysis. Experiments were designed to investigate the potential usefulness of DFI/GC for determining the organic fraction and unburned lubricating oil contributions of diesel particulate emissions for future technology engines. A 1991 Caterpillar 3176 was used to generate samples during several heavy-duty engine test cycles, including the cold- and hot-start transient FTP and several steady-state conditions. Particulate-laden filter samples were then analyzed for organics by DFI/GC, solvent extraction, and vacuum volatilization. Results obtained using the three techniques were compared using statistical analysis techniques. Results showed that DFI/GC is extremely useful for directly determining the organic fraction of diesel particulate, and provides a better estimation of unburned lubricating oil contribution to the organic fraction than the other methods evaluated.

Diffraction Patterns

A study has been made of the morphology and crystallography of particulate emissions from indirect injection diesel engines. This particulate matter consists substantially of carbon (although hydrocarbons can be extracted with solvents). Samples were collected in a diluted exhaust stream on amorphous carbon films and examined in a JEM-200C electron microscope operated in the TEM mode with an accelerating voltage of 200 KV.The morphology of the diesel particles, as shown in Fig. 1, markedly resembles carbon blacks and consists of an agglomeration of quasispherical subunits arranged in chains or clusters. Only limited changes in morphology were observed as the number of subunits in the particle increased (although larger particles tended to be more cluster-like than the extended chain shown in Fig. 1). However, a dramatic effect of the number of subunits was observed on the character of the diffraction pattern. Smaller particles yielded a diffraction pattern consisting of very diffuse rings typical of turbostratic carbon; the diffraction patterns from the larger particles, however, although qualitatively similar, exhibited much sharper and less diffuse ring patterns.
