THE INFLUENCE OF CAVITATION ON SPRAY FORMATION OF DIESEL INJECTION NOZZLES . INTEGRATED DIESEL EUROPEAN ACTION (IDEA) 1. AUTOTECH 89 SEMINAR PAPERS

In a study of diesel engine combustion efficiency, using a modified single hole diesel fuel injector with a nozzle hole made of glass, pictures of the cavitating flow were made at different pressure differences. The inlet corner of the nozzle hole is sharp. Preliminary results for stationary flow in the nozzle hole at various pressure differences prove that cavitation is present in the nozzle hole above a limiting value. Large cavitation films are formed, which start at the nozzle hole inlet and extend at higher pressure differences into the liquid jet outside of the nozzle. In this second limiting case the jet angle starts to diverge and atomization begins to be very effective. For the covering abstract for this volume of seminar papers see IRRD 832432.
