Summary:

The effect of sampling conditions on the diesel exhaust aerosol characteristics has been studied so far with the application of Electrostatic Classifiers under steady state conditions. This paper aims at examining the same effects with application of an Electrical Low Pressure Impactor under transient engine operating conditions. Explanation of the results obtained takes into account the different operational characteristics of this new technique (recorded magnitude, size range and resolution). The study confirms particle formation in the dilution tunnel and downstream of a DPF and also coagulation of liquid particles in the tunnel. However, separation of the liquid particle phase has led to modification of the aerosol properties in a direction which may be conversely recorded by instruments based on different operation principles
