Effective Density of Diesel Exhaust Particles as a Function of Size 2002-01-0056
New method to define the particle effective density as a function of particle size has been applied to diesel vehicle exhaust particles. The results show that, the effective density of agglomerated diesel particles decreases as a function of particle size. The density of primary particles varies from 1.1 to 1.2 g/cm3. Also the effect of used dilution method and fuel type on particle density was studied. The dilution effect seems to have stronger effect on particle effective density and structure than the fuel type.
