Experimentelle Untersuchungen und Numerische Simulation der Geometrie technischer Stroemungsdrosseln fur "Common Rail"-Direkteinspritzsysteme (Experimental Examinations and Numerical Simulation of the Geometry of Technical Flow Throttles for "Common Rail" Direct Injection Engine Systems)
Abstract
This dissertation concerns itself with direct injection engine systems and, more specifically, with the examination of technical flow throttles, which are set into an injector in order to control the switch procedure. An optimization with regard to the switch process and efficiency is targeted, so that a particular profile of the throttles might be attained. As far as the throttle profile is concerned, modifications included relate to the diameter and length, a possible conical form of the throttle canal as well as a touching, to some degree, a rounding of the inlet and outlet edges of the throttle. The parameters employed subsequently succeed in simulations with various models, such as with oil, and then with water.
