This work reports the results of a X-ray µ-tomography for investigating the inner structure of high pressure fuel sprays. X-ray imaging is widely used in a multitude of industrial applications where non-destructive tests are required for high accuracy measurements of samples morphology. Synchrotron X-ray source is generally used for fuel sprays investigation because its high flux radiation can overcome the troubles linked to the low absorption of hydrocarbon chains as fossil fuels. Recently, a desktop facility has successfully used to characterize high pressure gasoline sprays for automotive applications . A X-ray tube coupled with polycapillary optics provided low divergence, high flux beam. This paper reports the last improvement concerning the quantitative measurements preformed on fuel sprays.
