Abstract

Physical characterization of the exhaust aerosols produced by two diesel-powered automobiles was done using the Mobile Air Pollution Laboratory (UMML) built by the University of Minnesota Particle Technology Laboratory. The two automobiles were a VW Rabbit and an Oldsmobile 5. 7 liter V-8. Plume dilution ratios were measured using NO//x as a tracer gas. Samples were taken in the exhaust plume at a point approximately one second after exhaust. Aerosol number, surface and volume concentration, and size distribution were measured using an electrical aerosol analyzer contained in the UMML. The total number concentration of submicron aerosol was measured using a condensation nuclei counter. General characteristics of the roadway aerosol size distribution were similar to those measured when using a jet pump diluter in laboratory dynamometer studies.
