Definitions
- the invention relates to an exhaust gas introduction device for an internal combustion engine for introducing exhaust gas by means of at least one opening in a Ansaugkanalab bain a suction tube, with an exhaust gas supply section, an exhaust gas recirculation valve and a Abgaseinleitblech, which forms an annular channel with the band region of the Ansaugkanalabitess.
- Such Abgaseinleitvoriques is from the DE-A-19645280 known.
- a ring channel is formed by a seal, which is correspondingly formed, between the Ansaugkanalabsacrificing, wherein the seal is formed so that the annular channel is connected via an annular opening with the intake passage.
- Such a Abgaseinleitvoriques has the disadvantage that the seal must be precisely formed, and the assembly process is difficult in that there is a uniform annular opening for introducing the exhaust gas in the assembled state.
- the invention is therefore based on the object to further develop a generic Abgaseinleitvorraum to the effect that it is inexpensive to manufacture and easy to assemble.
- the Abgaseinleitblech is designed as a stamped part with deformable webs, such that the webs define the annular channel with openings in the installed state of Abgaseinleitbleches.
- the Abgaseinleitblech is also a seal.
- the Abgaseinleitblech has further openings which correspond to line sections of the intake manifold and the exhaust gas recirculation valve, it is possible to easily realize by means of a component, the exhaust gas inlet into the intake manifold, wherein the Abgaseinleitblech the individual line sections seals against each other.
- FIG. 1 shows an exhaust gas introduction device 1, which at a suction pipe 2 for the introduction of exhaust gas into a Ansaugkanalab Songs 3 (s. FIG. 2 ) is arranged.
- the Abgaseinleitvoriques 1 consists in the present embodiment, essentially of a schematically illustrated exhaust gas recirculation valve 4 and an exhaust gas inlet 5, wherein the Abgaseinleitblech is also formed as a seal through which the exhaust gas recirculation valve 4 is flanged sealed on the intake manifold. Furthermore, in FIG. 1 a cooling device 6 is shown, via which the exhaust gas cooled to the exhaust gas recirculation valve 4 can be performed.
- the exact design of the Abgaseinleitbleches 5 and its change function together with the suction pipe 2, the exhaust gas recirculation valve 4 and the radiator 6 will be described later with reference to FIG. 3 clarified.
- the exhaust gas recirculation valve 4 is an upwardly acting Valve rod 7 having a valve plate 8, which can open or close a valve inlet 9 an exhaust gas supply section 10.
- FIG. 2 shows now in a side view the exhaust gas inlet plate 5 just before mounting on the intake manifold 2 with a Ansaugkanalabites 3. Clearly visible are already formed webs 11 of Abgaseinleitbleches. Further shows FIG. 2 schematically a section of a cooling device 12 with a coolant channel 13 and exhaust ducts 14, wherein the guided in the exhaust gas channels 14 exhaust gas is cooled in a known manner by the coolant in the coolant channel 13.
- FIG. 3 shows in a plan view the exhaust gas inlet plate 5 as a stamped part.
- the webs 11 are not transformed.
- the webs 11 together with the wall portion of the intake passage 3 of the suction tube 2 form an annular channel via the known manner exhaust gas to the intake passage 3 is supplied. This is done by means of openings 12, which, as from FIG. 2 can be seen by the forming of the webs 11 arise.
- openings 15, 16, 17 are shown, which correspond to corresponding channels.
- the exhaust gas is fed to the exhaust gas recirculation valve 4 via the opening 15, while the openings 17 correspond to the coolant channel 13 and the openings 16 with the exhaust gas channels 14.

Description
- Die Erfindung betrifft eine Abgaseinleitvorrichtung für eine Brennkraftmaschine zur Einleitung von Abgas mittels mindestens einer Öffnung in ein Ansaugkanalabschnitt eines Saugrohres, mit einem Abgaszuleitungsabschnitt, einem Abgasrückführventil und einem Abgaseinleitblech, das mit dem Bandbereich des Ansaugkanalabschnitts ein Ringkanal bildet.
- Eine derartige Abgaseinleitvorrichtung ist aus der
DE -A1- 196 45 280 bekannt. Hierbei wird durch eine Dichtung, die entsprechend umgeformt ist, zwischen dem Ansaugkanalabschnitt ein Ringkanal gebildet, wobei die Dichtung so geformt ist, daß der Ringkanal über eine ringförmige Öffnung mit dem Ansaugkanal verbunden ist. Eine derartige Abgaseinleitvorrichtung besitzt den Nachteil, daß die Dichtung präzise umgeformt sein muß, und der Montagevorgang dahingehend schwierig ist, daß eine gleichmäßige ringförmige Öffnung zum Einleiten des Abgases im montierten Zustand vorliegt. - Der Erfindung liegt daher die Aufgabe zugrunde, eine gattungsgemäße Abgaseinleitvorrichtung dahingehend weiter zu bilden, daß sie kostengünstig herzustellen und auf einfache Weise zu montieren ist.
- Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Abgaseinleitblech als Stanzteil mit umformbaren Stegen ausgeführt ist, derart, daß die Stege im eingebauten Zustand des Abgaseinleitbleches den Ringkanal mit Öffnungen definieren.
- Eine derartige Abgaseinleitvorrichtung ist besonders einfach und kostengünstig herzustellen, wobei auch die Montage lediglich einen geringen Justieraufwand benötigt.
- Vorzugsweise ist das Abgaseinleitblech auch eine Dichtung.
- Dadurch daß das Abgaseinleitblech weitere Öffnungen aufweist, die mit Leitungsabschnitten des Saugrohres und des Abgasrückführventils korrespondieren, ist es möglich auf einfache Weise mittels eines Bauteiles die Abgaseinleitung in das Saugrohr zu realisieren, wobei das Abgaseinleitblech die einzelnen Leitungsabschnitte gegeneinander abdichtet.
- Im folgenden wird unter Bezugnahme auf die Zeichnung ein Ausführungsbeispiel der Erfindung näher erläutert.
- Es zeigen:
- Figur 1
- eine Seitenansicht der erfindungsgemäßen Abgaseinleitvorrichtung,
- Figur 2
- eine Seitenansicht im Schnitt eines Teiles eines Saugrohres mit dem beabstandeten Abgaseinleitblech kurz vor der Montage, und
- Figur 3
- eine Draufsicht des Abgaseinleitbleches nach dem Austanzvorgang.
-
Figur 1 zeigt eine Abgaseinleitvorrichtung 1, die an einem Saugrohr 2 zur Einleitung von Abgas in einen Ansaugkanalabschnitt 3 (s.Figur 2 ) angeordnet ist. Die Abgaseinleitvorrichtung 1 besteht im vorliegenden Ausführungsbeispiel im wesentlichen aus einem schematisch dargestellten Abgasrückführventil 4 und einem Abgaseinleitblech 5, wobei das Abgaseinleitblech gleichzeitig als Dichtung ausgebildet ist, durch die das Abgasrückführventil 4 abgedichtet am Saugrohr angeflanscht ist. Des weiteren ist inFigur 1 noch eine Kühleinrichtung 6 dargestellt, über die das Abgas gekühlt zum Abgasrückführventil 4 geführt werden kann. Die genaue Ausbildung des Abgaseinleitbleches 5 und seine Wechselfunktion zusammen mit dem Saugohr 2, dem Abgasrückführventil 4 und dem Kühler 6 werden später anhand derFigur 3 verdeutlicht. - Es sei noch angemerkt, daß aus der schematischen Darstellung des Abgasrückführventiles 4 zu erkennen ist, daß das Abgasrückführventil 4 eine nach oben wirkende Ventilstange 7 mit einem Ventilteller 8 aufweist, der über einen Ventilsitz 9 einen Abgaszuleitungsabschnitt 10 öffnen oder verschließen kann.
-
Figur 2 zeigt nun in einer Seitenansicht das Abgaseinleitblech 5 kurz vor der Montage am Saugrohr 2 mit einem Ansaugkanalabschnitt 3. Deutlich zu erkennen sind die bereits umgeformten Stege 11 des Abgaseinleitbleches. Des weiteren zeigtFigur 2 auf schematische Weise einen Ausschnitt einer Kühleinrichtung 12 mit einem Kühlmittelkanal 13 und Abgaskanälen 14, wobei das in den Abgaskanälen 14 geführte Abgas auf bekannte Weise durch das Kühlmittel im Kühlmittelkanal 13 gekühlt wird. -
Figur 3 zeigt in einer Draufsicht das Abgaseinleitblech 5 als Stanzteil. Hierbei sind die Stege 11 noch nicht umgeformt. Nach dem Umformen der Stege 11 und der Montage am Saugrohr 2 bilden die Stege 11 zusammen mit dem Wandbereich des Ansaugkanalabschnittes 3 des Saugrohres 2 einen Ringkanal über den auf bekannte Weise Abgas dem Ansaugkanalabschnitt 3 zugeführt wird. Dies geschieht dabei mittels Öffnungen 12, die, wie ausFigur 2 ersichtlich, durch das Umformen der Stege 11 entstehen. - Des weiteren sind Öffnungen 15, 16, 17 dargestellt, die mit entsprechenden Kanälen korrespondieren.
So wird über die Öffnung 15 das Abgas dem Abgasrückführventil 4 zugeleitet, während die Öffnungen 17 mit dem Kühlmittelkanal 13 und den Öffnungen 16 mit den Abgaskanälen 14 korrespondieren.
