摘要：

Imaging of two dimensional diesel spray flame in a rapid compression machine (RCM) laser sheet by the process of ignition and soot formation process was analyzed. The laser induced fluorescence (LIF) of formaldehyde was formed in a fuel spray during ignition process by exciting the formaldehyde with the third harmonic of an Nd:Yag laser. It was observed that formaldehyde disappeared when the temperature was increased and this disappearance position moved from the spray periphery to the central region of the spray. The first appearance of the LIF from the soot precursor in the spray flame preceded the appearance of the LII from soot particles and reached its maximum after the end of injection.
