To make clear the behavior of particulate matter (PM) and its precursor in a diffusion flame of diesel fuel, measurements of polycyclic aromatic hydrocarbons (PAHs) and PM were carried out. A sooting diffusion flame formed by a small pool combustion equipment were used for this purpose. Spatial distributions of PAHs in the diffusion flame were visualized by a laser induced fluorescence (LIF) method. PAHs concentrations were measured quantitatively using a gas chromatography (GC). Spatial distributions of PM in the test flame were also measured by a laser induced incandescence (LII) method. Average size of dry soot particles in PM was estimated from temporal changes of LII intensity. Moreover, PM size of the test flame was measured by a scanning mobility particle sizer (SMPS). Dry soot, soluble organic fraction (SOF) and sulfate components in PM were also measured by a PM analyzer. From these results, lighter PAHs such as benzene and toluene were changed gradually to heavier PAHs such as pyrene at the upstream part in flame. Lighter PAH species which did not change to heavier PAH species were remained in the sooting region and was released from the flame tip into surroundings.
