An Experimental Study on the Characteristics of Nanoparticles Emission from a Vehicle

Article Preview

Abstract:

The Fast Mobility Particle Sizer (FMPS) has been used to measure the particles number concentration and size distribution (6-560nm) of vehicle exhaust plume. The results reveal that vehicle exhaust contribute dominantly to the number concentration in the atmosphere particle. The particles total concentration decreases in the dispersion process. Furthermore, the transformation processes such as nucleation ,coagulation and condensation happen with dispersion process. Because of large number of nucleation mode particles, the coagulation process is in the advantage, which make the particles diameter increase.
