Figure 5

Degrees of fragmentation as a function of the kinetic impact energy for aged agglomerate particles of diesel exhaust aerosol, measured with and without thermal denuder (TD). Also shown for information is the data for the primary diesel soot aerosol, which cannot be fragmented at all. The theoretical van-der-Waals bond energy distribution was calculated for a typical diesel soot agglomerate. (Note that the kinetic energy is based on the mass mean primary particle diameter. The diagram thus represents a bond energy distribution of primary particles.)
