Particulate emissions from IC engines associated with transient engine conditions are very important (similar to the legislated gaseous emissions). This is true both during real-world and test cycle driving. This paper describes an instrument for measuring the number of particles, and their spectral weighting, in the 5nm to 1000nm size range, with a time response of 200ms. This is achieved via an electrostatic classification technique, consisting of a diffusion charger followed by a multi-element, constant voltage, classifier. Conversion of the data to other metrics, such as mass, is also described. Results are presented from artificial test aerosols and from light and heavy duty diesel engines on standard test cycles.
