Title: Verfahren zur internen Abgasrückführung bei mehrzylindrigen Brennkraftmaschinen
Inventor: NEITZ MICHAEL
IPC: F02M26/01
Filed: 1999-05-18
Abstract: Die Erfindung bezieht sich auf ein Verfahren zur internen Abgasrückführung für mehrzylindrige Brennkraftmaschinen. Ein besonderes Problem für Dieselmotoren ist die Reduzierung der Stickoxide. Ein Weg zur Lösung dieses Problems stellt die Abgasrückführung dar. Gelöst wird die Abgasrückführung erfindungsgemäß zum einen dadurch, daß durch das Öffnen eines ersten Auslasses eines ersten Zylinders, welcher sich am Ende eines Expansionstakts befindet, eine Druckwelle entsteht, welche sich im gemeinsamen Abgaskrümmer fortpflanzt, daß während der Öffnung des ersten Auslasses ein zweiter Auslaß eines zweiten Zylinders, der sich in einem Ansaugtakt oder in einer frühen Phase eines Verdichtungstakts befindet, über die für den eigentlichen Gaswechsel erforderliche Öffnungsdauer hinaus offen gehalten wird und daß durch die Druckwelle über den zweiten offen gehaltenen Auslaß Abgas in den zweiten Zylinder zurückgeführt wird. Ein anderer Lösungsweg besteht darin, daß ein Einlaß eines im Expansionstakt befindlichen Zylinders gegen Ende der Expansion geöffnet wird, so daß durch die, zu diesem Zeitpunkt positive Druckdifferenz zwischen Zylinder und zugehörigem Einlaßkanal Abgas in diesen Einlaßkanal des Zylinders oder in eine davor liegende Leitung zurückströmt und daß die Rückführrate an Abgas durch Lage und Dauer der Öffnung des Einlasses gesteuert wird. Beide Lösungen erfordern nur relativ kleine bauliche Veränderungen an der Nockenwelle, zusätzliche Ventile werden nicht benötigt.

Patent DE-19931846-A1 (DE)
Inventor: NEUBERT JOACHIM
IPC: B01D69/14
Filed: 1999-07-09
Abstract: The invention relates to a membrane that is used as a composite membrane for the separation of dissolved and suspended substances and dissolved salts from their carrier liquid. Said membrane consists of a flat substrate with relatively wide through-flow openings on which a separating layer is applied that consists of a composite of a granular filler and a binder. The inventive separating layer consists of at least two superimposed interlinked constructional layers of different structure. The superimposed constructional layers applied on the substrate contain respective graded sequences of filler ratios and correspondingly higher binder ratios as compared to a preceding constructional layer. When the membrane is operational and fitted in a separation installation, the separating layer is oriented in such a manner that the constructional layer with the lowest filler ratio is impinged by the liquid that contains the substances to be separated. The inventive membrane structure allows a substantial reduction of the inner resistance to flow of the membrane. At the same time, a high flux can be achieved at a relatively low transmembrane pressure and a relatively low overflow rate.

IPC: G06F17/30
Filed: 2000-02-15
Abstract: A method and system for transforming an intermediate form into an object-oriented
database. The intermediate form is derived from a grammatical form of an
object-oriented database through the process of compilation. The grammatical form is an
expression of an object-oriented database in a textual form according to a grammar. The
intermediate form comprises an array of intelligent entry objects that encapsulate data
with methods for manipulating that data. The intermediate form comprises entries as in
the object-oriented database but lacks the infrastructure of the database. The intermediate
form can be used to populate the object-oriented database with entries. Population takes
place through a public API for accessing the object-oriented database; in other words,
through an interface which declares methods for navigating the database and adding
entries to the database. The object-oriented database is an object-oriented configuration
database which stores configuration parameters pertaining to the software and hardware
of a computer system, such as application programs, device drivers, system services, and
other components. The object-oriented database is platform-independent and is therefore
configured to be hosted on several different operating systems and computing platforms.
