The Physical and Chemical Character of Diesel Particulate Emissions-Measurement Techniques and Fundamental Considerations 780108
The techniques used to characterize the chemical and physical nature of particulates in diesel exhaust emissions are reviewed. The emphasis is on understanding the broader aspects of the fundamental nature of not only diesel particulates, but particulate systems in general. Consideration is given to the special nature of particulates which make them significant pollutants and to the relative place of the diesel in the formation of man-made particles.
The underlying combustion processes leading to carbon and sulfur based particulates are reviewed. The important variables in steps of the combustion processes which lead to particulate formation are considered, as well as major fuel and engine factors.
Collection methods are examined with examples given from current diesel dilution techniques. Probes, sampling lines, and instrumentation are considered. Methods of physical and chemical characterization are presented and examples from the current and prior diesel work at Michigan Technological University and elsewhere are given.
