For the reduction of diesel engine emissions, it is significant to clarify the spray atomization and formation processes. In this investigation, a detailed observation of fuel droplets characteristic was made by applying a double exposure method using a color film, a light fiber and a wavelength converter to a previous measurement technique. The photographic system is composed of a specialized lens system, and enables to measure the whole spray shape and fuel droplets characteristics at an instant. The light source is the second harmonic, and the third harmonic of Nd:YAG laser. This technique enables the spray measurement of the chronological order. In addition, it is expected new knowledge about a spray atomization mechanism be obtained.
