Kennaird, D., CRUA, CYRIL, HEIKAL, MORGAN, MORGAN, ROBERT, Bar, F. and Sapsford, S. (2000) A new high-pressure diesel spray research facility In: IMechE international conference on computational and experimental methods in reciprocating engines, London, UK, 1-2 Nov, 2000.
The application of high pressure advanced fuel injection equipment allows for better control of spray mixing, which ultimately can lead to a more favourable trade-off in noise, soot and NOx formation across the engine operating map. The new Diesel research facility at the University of Brighton has been specifically designed to enable the study of Diesel sprays at realistic automotive in-cylinder conditions while simultaneously providing excellent optical access for both qualitative and quantitative measurements of the combusting/non-combusting spray. The rig is constructed around a single cylinder two-stroke Diesel engine with a specially designed optical chamber incorporated between the cylinder and head. Spray cone angle and penetration data extracted from photographic and high-speed video studies undertaken in the test rig are presented. Injection pressures of 160 MPa and in-cylinder pressures of 10 MPa were achieved.
