Description
Table-top experiment using a microfocus X-ray source for radiography and tomography has been used for investigating the structure of a gasoline pulsed spray flowing from a GDI injector for automotive applications. A Cu Kα X-ray source at 8.048 keV in combination with a polycapillary halflens has been used to focus the radiation on the spray while a CCD detector collected the resulting signal. The fuelling apparatus feeds an injector inserted in a high-pressure rotating device actuated with angular steps Delta(Teta)= 1°. The acquisition has been carried out on 180° angular trip at the injection pressure of 8.0 MPa. The image processing has permitted sinogram reconstructions of the jets by slices allowing a 360° spray access to the spatial and temporal distribution of the fuel downstream the nozzle tip.
