Schematic of the gasoline fuel injection experimental set-up. The X-ray beam from the CHESS D-1 beamline is monochromated to 6.0 keV using a double-multilayer monochromator and collimated to 15 mm (H) × 2 mm (V) by a set of slits. The gasoline fuel injector is mounted vertically along the rotation axis of an injection chamber having X-ray transparent mylar windows. Nitrogen flow at 1 atm is used to scavenge fuel vapor. Time-resolved tomographic data are acquired by recording time-resolved radiographs at each of a number of projection angles using the PAD. (From Liu et al., 2004.) |
