Gas density and rail pressure effects on diesel spray growth from a heavy-duty common rail injector

Formation of nonevaporating sprays from diesel fuel injection through a realistic heavy duty multihole common rail injector is studied in a newly developed high-pressure, high-temperature cell, using digital highspeed shadowgraphy at 4500 frames/s. Gas pressure was varied from 13 to 37 bar (corresponding to densities of 15-42 kg/m3, using N2 at...
