The characteristics of a diesel spray, such as the diameter, the velocity and the droplet distribution on a 2D plane were simultaneously measured by using an improved ILIDS (Interferometric Laser Imaging for Droplet Sizing) method. The experiments were performed with an accumulator type unit injector system and a constant-volume high-pressure vessel under the condition of quiescent ambient gas. The injection pressure and ambient gas pressure were set at 60/100 MPa and 0.1/1 MPa, respectively. The injection duration was set at 2ms, and measurements were made at 1.5ms after the end of injection. The orifice diameter of the injector used was 0.24mm with a single hole. The measurement was made at 40-60mm from the nozzle-tip. As a result, the correlations between the droplet size, the velocity and the spatial distribution were found under different injection and ambient gas pressures.
