Experimental aspects of size distribution measurements of vehicle particulate emissions
The awareness of health effects of ultra fine particles has increased the interest in particle size distributions and number concentrations of vehicle emissions. The measuring technique of these quantities have, however, not reached the quality level of total particulate mass measurements, which are routinely applied for emission tests according to current regulations. This report summarises the results of experiments that were made to analyse aspects of the performance and the correlation of different methods and instruments for size distribution measurements. A Scanning Mobility Particle Sizer (SMPS), a second electrical mobility analyser and a Low Pressure Impactor (LPI) were used for comparative measurements. The particle sizing instruments and the system for sampling and dilution were tested using a graphite test aerosol and emissions of different vehicles and engines.
