Abstract

Description

Die Erfindung betrifft eine Medientrennanordnung zur Verwendung in einer Abgasrückführeinrichtung.The invention relates to a media separation arrangement for use in a Exhaust gas recirculation device.

Abgasrückführeinrichtungen sind hinlänglich bekannt. Dabei ist in einem Luftansaugkanal eine durch einen Ventilkörper verschließbare Abgasaustrittsöffnung eines Abgaskanals derart angeordnet, dass von der Brennkraftmaschine erzeugtes Abgas in den Luftansaugkanal und damit zu den Ansaugtrakten der einzelnen Zylinder der Brennkraftmaschine zur Verminderung der Stickoxidmenge der Brennkraftmaschine rückgeführt werden kann. Ein direktes Auftreffen des heißen Abgases aus dem Abgaskanal auf die Frischluft im Luftansaugkanal kann in Verbindung mit der an den Kanalwänden des Luftansaugkanals abgesetzten Flüssigkeit wie z. B. (Blowby, Kondensat etc.) zur Ablagerung von Verschmutzungspartikeln wie z. B. Ruß an den Kanalwänden des Luftansaugkanals oder am Ventilschließkörper führen, was wiederum die Funktion der Abgasrückführeinrichtung beeinträchtigen kann.Exhaust gas recirculation devices are well known. It is in one Air intake duct an exhaust outlet opening that can be closed by a valve body an exhaust gas duct arranged such that generated by the internal combustion engine Exhaust gas in the air intake duct and thus to the intake tracts of the individual Cylinder of the internal combustion engine to reduce the amount of nitrogen oxide Internal combustion engine can be recycled. A direct impact of the hot Exhaust gas from the exhaust duct to the fresh air in the air intake duct can in Connection with that deposited on the duct walls of the air intake duct Liquid such as B. (blowby, condensate, etc.) for the deposition of Pollution particles such as B. Soot on the duct walls of the air intake duct or lead on the valve closing body, which in turn the function of Exhaust gas recirculation device can impair.

Hiervon ausgehend liegt der Erfindung daher die Aufgabe zugrunde den oben genannten Nachteil zu vermeiden.Proceeding from this, the invention is therefore based on the object above to avoid the disadvantage mentioned.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass eine Medientrennanordnung zum Einleiten von Abgas in einen Luftansaugkanal mit einem Strömungsleitkörper und mit Rastmitteln, die im Wandbereich des Luftansaugkanals einrastbar sind, vorgesehen sind.This object is achieved in that a Media separation arrangement for introducing exhaust gas into an air intake duct with a Flow guide and with locking means in the wall area of the air intake duct are clickable, are provided.

Auf diese Weise wird eine Trennung von Abgas und Frischluft in verschmutzungskritischen Bereichen des Abgasrückführmischgehäuses erreicht. Die Funktion der mechanischen Bauteile sowie die Abgas- und Frischluftströmungsquerschnitte sind über eine lange Lebensdauer gewährleistet. Dabei ist der Strömungsleitkörper ein im wesentlichen rechteckförmiges, abgebogenes Blechteil mit angeformten Rastmitteln, die als Rastnasen und als Ringeinsatz ausgebildet sind. Auf diese Weise wird gewährleistet, dass die Medientrennanordnung auf einfachste Weise in das Abgasrückführmischgehäuse einsetzbar ist, wobei der Strömungsleitkörper dafür sorgt, dass eine Vermischung der beiden Medien Abgas und Frischluft erst weit hinter dem Ventilschließglied erfolgt.In this way, a separation of exhaust gas and fresh air is in dirt-critical areas of the exhaust gas recirculation mixer housing reached. The  Function of the mechanical components as well as the exhaust and Fresh air flow cross sections are guaranteed over a long service life. The flow guide body is an essentially rectangular, bent sheet metal part with molded locking means, which as locking lugs and as Ring insert are formed. This ensures that the Media separation arrangement in the simplest way in the exhaust gas recirculation mixing housing can be used, the flow guide body ensuring that mixing of the Both media exhaust gas and fresh air only take place far behind the valve closing element.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird nachfolgend beschrieben:An embodiment of the invention is shown in the drawing and will described below:

Diese zeigt:This shows:

Fig. 1 eine erfindungsgemäße Medientrennanordnung in einer perspektivischen Ansicht, Fig. 1 is a media separating arrangement of the invention in a perspective view;

Fig. 2 eine teilweise geschnittene Abgasrückführeinrichtung mit eingesetzter Medientrennanordnung in einer perspektivischen Ansicht. Fig. 2 is a partially sectioned exhaust gas recirculation device with an inserted media separation arrangement in a perspective view.

Fig. 1 zeigt eine erfindungsgemäße Medientrennanordnung 1 in einer perspektivischen Ansicht. Die Medientrennanordnung 1 besteht im wesentlichen aus einem rechteckförmigen, abgebogenen Blechteil 2 sowie Rastnasen 3 und einem Ringeinsatz 4, die als Rastmittel derart in Wandbereiche 5 eines Luftansaugkanals 6 (siehe Fig. 2) einrasten, bis die Medientrennanordnung 1 verdreh- und verschiebsicher im Luftansaugkanal 6 angeordnet ist. Fig. 1 shows a media separating arrangement 1 according to the invention in a perspective view. The media separation arrangement 1 essentially consists of a rectangular, bent sheet metal part 2 as well as locking lugs 3 and a ring insert 4 , which engage as locking means in wall areas 5 of an air intake duct 6 (see FIG. 2) until the media separation arrangement 1 is secured against rotation and displacement in the air intake duct 6 is arranged.

Fig. 2 zeigt eine Abgasrückführeinrichtung 7 mit der Medientrennanordnung 1 die mittels der Rastmittel 3, 4 derart im Luftansaugkanal eingesetzt ist, dass der Strömungsleitkörper 2 im Bereich einer Austrittsöffnung 8 eines Abgaskanals angeordnet ist. Auf diese Weise wird gewährleistet, dass aus dem Abgaskanal bei geöffnetem Ventilschließglied 9 ausströmendes Abgas nicht direkt mit der im Luftansaugkanal strömenden Frischluft in Kontakt kommt, was zur Verschmutzung von kritischen Teilen wie dem Abgasrückführventil 10 oder dem Querschnitt des Luftansaugkanals 6 führen könnte. Fig. 2 shows an exhaust gas recirculation device 7 with the media separating arrangement 1 which is used by means of the locking means 3, 4 in such a way in the air intake duct that the flow guide 2 of an exhaust passage is arranged in the region of an outlet opening 8. This ensures that exhaust gas flowing out of the exhaust duct when the valve closing member 9 is open does not come into direct contact with the fresh air flowing in the air intake duct, which could lead to contamination of critical parts such as the exhaust gas recirculation valve 10 or the cross section of the air intake duct 6 .
