Abstract
An experimental platform for high-speed video recording of fuel jet spraying and applicability of the platform for studying the liquid fuel jet spraying are discussed in the paper. Fuel spraying quality is evaluated by the jet cross-sectional area. Axial section data show the dynamics of normalized brightness areas of diesel jet and RME values within the injection pressure range from 60 MPa to 180 MPa. A pixel separation method for the fuel jet image with clusterization to determine object boundaries is proposed. The region of interest of a fuel jet (i.e. an area on an image) is shown with a low brightness and indicates a high fuel concentration while an area wi...
