Abstract: European regulation for Euro 5/6 light duty emissions introduced the particle number concentration measurement of non-volatile particles with electrical mobility diameter >23 nm. The volatile phase is removed by using a heated dilution stage (150 °C) and a heated tube (at 300-400 °C). We investigated experimentally the volatile removal efficiency of the specific protocol by conducting measurements with two Euro 3 diesel light duty vehicles, a Euro 2 moped, and a Euro III heavy duty vehicle with the system¿s heaters on and off. The particle number distributions were measured with a Scanning Mobility Particle Sizer (SMPS) and a Fast Mobility Particle Sizer (FMPS). An Aerosol Mass Spectrometer (AMS) was used to identify the non-refractory chemical composition of the particles. A Multi-Angle Absorption Photometer (MAAP) was used to measure the black carbon concentration. The results showed that the condensed material on the accumulation mode (i.e. particles in the range of 50-500 nm) was efficiently removed (50-90%). The (volatile) nucleation mode was also completely evaporated or was decreased to sizes <23 nm; thus these particles wouldn¿t be counted from the particle counter, indicating the robustness of the protocol.
