A time‐resolved radiographic technique has been developed for probing the fuel distribution close to the nozzle of a high‐pressure single‐hole diesel injector. The measurement was made using X‐ray absorption of monochromatic synchrotron‐generated radiation, allowing quantitative determination of the fuel distribution in this optically impenetrable region with a time resolution of better than 1 µs. These quantitative measurements constitute the most detailed near‐nozzle study of a fuel spray to date.
