Comparison between images of hollow-cone direct-injection gasoline sprays taken by visible-light shadowgraphy and X-radiography, at the same time instance and under the same injection conditions. Owing to serious multiple scattering by the spray near the nozzle, quantitative evaluation of the fuel density in this region has been difficult with the optical imaging technique. By contrast, the X-ray image directly relates the absorption data to the fuel mass in the X-ray beam. Both the shadowgraph and the X-radiograph are averages of 20 shots.
