• In this study, the spray from a multi-hole GDI injector has been characterized applying the Imaging and the Phase Doppler Anemometry techniques. A multi-holes injector, with a hollow-ellipsoid footprint structure, has been used. The spray pattern evolution has been analyzed injecting commercial gasoline at different injection pressures (10, 15 and 20 MPa). Pictures of the spray sequence have been captured, injecting the fuel in an optically accessible vessel at quiescent air conditions, ambient temperature and atmospheric backpressure, at different instant from the start of injection. The spray has been illuminated by high intensity flashes, synchronized with the injection system, that have allowed to capture the emerging fuel by a CCD camera, 1370 x 1048 pixels, 0.5 ¼s shutter time. The images have been processed by Image ProPlus software for extracting the main parameters of the spray evolution. Local characteristics of the spray have been investigated along the jet axis by the phase Doppler anemometry in order to provide the size and two components of the droplets velocity: the axial and the radial ones. Data have been analyzed using the ensemble averaging technique in order to provide mean values. Additionally, the Weber number has been evaluated in order to provide further details of the atomization process. (literal)
