Description
Die vorliegende Erfindung betrifft eine Sauganlage für eine Brennkraftmaschine, insbesondere in einem Kraftfahrzeug.The The present invention relates to an intake system for an internal combustion engine, especially in a motor vehicle.
Eine derartige Sauganlage dient zur Frischgasversorgung von Zylindern der Brennkraftmaschine. Üblicher Weise besitzt eine solche Sauganlage für mehrere Zylinder einen gemeinsamen Frischgasverteiler, der das Frischgas eingangsseitig von einem einzelnen Zuführungsrohr erhält und ausgangsseitig den zugeordneten Zylindern zuführt bzw, auf diese verteilt. Zu diesem Zweck besitzt der Frischgasverteiler für jeden zugeordneten Zylinder zumindest einen Frischgasaustritt, der im montierten Zustand der Sauganlage mit einem entsprechenden Frischgaseintritt kommuniziert, der im Motorblock der Brennkraftmaschine ausgebildet ist und darin zum Brennraum des jeweiligen Zylinders führt.A Such suction system is used for fresh gas supply of cylinders the internal combustion engine. usual Way has such a suction system for several cylinders a common Fresh gas distributor, the fresh gas input side of a single feed pipe receives and on the output side the associated cylinders feeds or, distributed to these. For this purpose, the fresh gas distributor has for each associated cylinder at least one fresh gas outlet in the assembled state of the intake system with a corresponding fresh gas inlet communicates formed in the engine block of the internal combustion engine is and leads to the combustion chamber of the respective cylinder.
Moderne Brennkraftmaschinen können mit einer Abgasrückführungseinrichtung, im folgenden AGR-Einrichtung, ausgestattet sein, die zumindest bei bestimmten Betriebszuständen der Brennkraftmaschinen einen Teilstrom der Abgase aus dem Abgasstrang der Brennkraftmaschine abzweigt und in das der Brennkraftmaschine zugeführte Frischgas zurückführt. Die Abgasrückführung erfolgt dabei in der Regel relativ weit stromauf der Frischgasaustritte und insbesondere stromauf des Frischgasverteilers, um bis zu den Frischgasaustritten eine möglichst gute Durchmischung der Abgase mit dem Frischgas zu erzielen. Beispielsweise ist die Abgasrückführung zur Einleitung der Abgase in die Sauganlage an das zuvor genannte Zuführungsrohr angeschlossen, das in den Frischgasverteiler führt. Mit Hilfe einer Kraftstoffrückführung kann für bestimmte Betriebszustände der Brennkraftmaschine deren Schadstoffemission reduziert werden.modern Internal combustion engines can with an exhaust gas recirculation device, in the following EGR facility, which at least at certain operating conditions the internal combustion engine, a partial flow of the exhaust gases from the exhaust system the internal combustion engine branches off and into that of the internal combustion engine supplied Fresh gas returns. The Exhaust gas recirculation takes place this usually relatively far upstream of the fresh gas outlets and in particular upstream of the fresh gas distributor, up to the fresh gas outlets as good as possible Mixing of the exhaust gases with the fresh gas to achieve. For example is the exhaust gas recirculation to Introduction of the exhaust gases into the intake system to the aforementioned supply pipe connected, which leads into the fresh gas distributor. With the help of a fuel return can for certain operating conditions the internal combustion engine whose pollutant emission can be reduced.
Die vorliegende Erfindung beschäftigt sich mit dem Problem, für eine Sauganlage der eingangs genannten Art eine verbesserte Ausführungsform anzugeben, die beispielsweise einen kompakten Aufbau ermöglicht und/oder sich vorteilhaft für die Leistungs- und/oder Emissionswerte der Brennkraftmaschine auswirkt.The present invention employs dealing with the problem, for an intake of the type mentioned an improved embodiment specify, for example, allows a compact structure and / or beneficial for the performance and / or emissions of the internal combustion engine effects.
Dieses Problem wird erfindungsgemäß durch den Gegenstand des unabhängigen Anspruchs gelöst. Vorteilhafte Ausführungsformen sind Gegenstand der abhängigen Ansprüche.This Problem is inventively the subject of the independent Claim solved. Advantageous embodiments are the subject of the dependent Claims.
Die vorliegende Erfindung beruht auf dem allgemeinen Gedanken, die Abgase möglichst nahe an sämtlichen Frischgasaustritten des Frischgasverteilers in die Sauganlage einzuleiten. Zu diesem Zweck verwendet die Erfindung einen Verteilerkanal, der am Frischgasverteiler so angeordnet ist, dass er sich entlang sämtlicher Frischgasaustritte, die diesem Frischgasverteiler zugeordnet sind, erstreckt. Das heißt, bei den Frischgasaustritten, die in einer Reihe nebeneinander benachbart angeordnet sind, erstreckt sich der Verteilerkanal vom ersten bis zum letzten Frischgasaustritt dieser Reihe. Durch diese Bauweise können die rückgeführten Abgase durch den Verteilerkanal unmittelbar stromauf jedes einzelnen Frischgasaustritts in den Frischgasverteiler eingeleitet werden. Da das rückgeführte Abgas auf die einzelnen Frischgasaustritte verteilt wird, ergibt sich für die einzelnen Zylinder jeweils eine hinreichende Durchmischung zwischen Frischgas und rückgeführtem Abgas.The The present invention is based on the general idea of the exhaust gases preferably close to all Fresh gas outlets of the fresh gas distributor to be introduced into the intake system. For this purpose, the invention uses a distribution channel, the is arranged on the fresh gas distributor so that it extends along all Fresh gas outlets associated with this fresh gas distributor, extends. This means, at the fresh gas outlets adjacent in a row next to each other are arranged, the distribution channel extends from the first to to the last fresh gas outlet of this series. By this construction can the recirculated exhaust gases through the distribution channel immediately upstream of each individual fresh gas outlet be introduced into the fresh gas distributor. Because the recirculated exhaust gas is distributed to the individual fresh gas leaks, results for the individual Cylinder each a sufficient mixing between fresh gas and recirculated exhaust gas.
Ein wesentlicher Vorteil der erfindungsgemäßen Bauweise wird darin gesehen, dass durch die unmittelbare Nähe des Verteilerkanals zu den Frischgasaustritten das Betriebsverhalten der Brennkraftmaschine im Hinblick auf die Abgasrückführung erheblich schneller an geänderte Randbedingungen angepasst werden kann. Beispielsweise wirkt sich eine Veränderung der Abgasrückführungsrate, im folgenden AGR-Rate, erheblich schneller auf das Betriebsverhalten der Brennkraftmaschine aus, da der Frischgasverteiler stets nur ein relativ kleines Volumen mit der vorhergehenden AGR-Rate enthält.One An essential advantage of the construction according to the invention is seen in that by the immediate proximity the distribution channel to the fresh gas outlets the operating behavior the internal combustion engine in terms of exhaust gas recirculation considerably faster at changed Boundary conditions can be adjusted. For example, one affects change the exhaust gas recirculation rate, in the following EGR rate, significantly faster on the performance the internal combustion engine, since the fresh gas distributor always only contains a relatively small volume at the previous EGR rate.
Von besonderem Vorteil ist eine Ausführungsform, bei welcher der Verteilerkanal in den Frischgasverteiler einstückig integriert ist, wobei Frischgasverteiler und Verteilerkanal insbesondere als integrales Gußteil ausgestaltet sein können. Durch diese integrierte Herstellung vereinfacht sich der Zusammenbau der Sauganlage, die dadurch außerdem sehr kompakt baut.From particular advantage is an embodiment in which the distribution channel integrated integrally into the fresh gas distributor is, fresh gas distributor and distribution channel in particular as integral casting can be configured. By this integrated manufacturing simplifies the assembly of the Intake system, which in addition very compact builds.
Entsprechend einer besonders vorteilhaften Ausführungsform kann der Verteilerkanal durch mehrere separate Rückführöffnungen mit dem Frischgasverteiler kommunizieren, wobei die Rückführöffnungen entlang des Verteilerkanals bezüglich der dem Frischgasverteiler zugeordneten Zylinder selektiv positioniert sind, und zwar vorzugsweise im Hinblick auf einen kurzen Strömungsweg von der jeweiligen Rückführöffnung zum selektierten Zylinder. Durch diese Bauweise erfolgt die Abgasrückführung nicht gleichmäßig über die gesamte Erstrekkung des Verteilerkanals, sondern gezielt an den Stellen, wo die rückgeführten Abgase auf dem kürzesten Weg zum jeweiligen Zylinder gelangen. Diese Bauweise steigert nochmals die Reaktionsfähigkeit der Brennkraftmaschine im Hinblick auf eine Änderung der AGR-Rate.Corresponding In a particularly advantageous embodiment, the distribution channel through several separate return openings communicate with the fresh gas manifold, with the return ports along the distribution channel with respect to the cylinder associated with the fresh gas manifold is selectively positioned are, preferably in view of a short flow path from the respective return opening to selected cylinder. Due to this design, the exhaust gas recirculation does not take place uniformly over the entire extension of the distribution channel, but specifically to the Ask where the recirculated exhaust gases on the shortest Get way to the respective cylinder. This construction increases again the responsiveness the internal combustion engine with respect to a change in the EGR rate.
Ein moderner Frischgasverteiler kann für jeden ihm zugeordneten Zylinder zwei nebeneinander angeordnete Frischgasaustritte, nämlich jeweils einen Hauptaustritt und jeweils einen Nebenaustritt, aufweisen. Mit Hilfe von zwei Frischgasaustritten je Zylinder ist es möglich, im jeweiligen Zylinder bzw. in dessen Trennraum eine Schichtladung herzustellen, wobei z.B. mit einer Drallströmung und/oder mit einer Tumbleströmung gearbeitet wird. Zweckmäßig kann dabei der Nebenaustritt zusätzlich gesteuert werden. Eine derartige Schichtladetechnik ist allgemein bekannt und muss daher nicht näher erläutert werden. Bei einer speziellen Weiter bildung der erfindungsgemäßen Sauganlage können nun die Rückführöffnungen entlang des Verteilerkanals bezüglich der Hauptaustritte oder bezüglich der Nebenaustritte selektiv positioniert sein, und zwar insbesondere im Hinblick auf einen kurzen Strömungsweg von der jeweiligen Rückführöffnung vom selektierten Austritt. Diese Bauweise führt dazu, dass das rückgeführte Abgas im wesentlichen nur durch den jeweils vorbestimmten Austritt den Frischgasverteiler verläßt. In der Folge können in den Zylindern bzw. in deren Brennräumen gezielt vorbestimmte Bereiche mit einem Abgas-Frischgas-Gemisch versorgt werden, während das übrige Brennraumvolumen im wesentlichen ausschließlich mit Frischgas befüllt wird. Mit Hilfe dieser lokal konzentrierten Abgasrückführung kann das Betriebsverhalten der Brennkraftmaschine, insbesondere Kraftstoffverbrauch und/oder Schadstoffemission positiv beeinflusst werden.A modern fresh gas distributor can have, for each cylinder assigned to it, two juxtaposed fresh gas outlets, namely one main outlet and one secondary outlet each. With the help of two fresh gas outlets each Cylinder, it is possible to produce a layer charge in the respective cylinder or in the separation space, for example, with a swirl flow and / or with a Tumbleströmung is used. Appropriately, the side exit can be additionally controlled. Such a layer loading technique is well known and therefore need not be explained in detail. In a specific further education of the intake system according to the invention, the return openings along the distribution channel with respect to the main outlets or with respect to the side exits can now be selectively positioned, especially with regard to a short flow path from the respective return opening from the selected outlet. This construction means that the recirculated exhaust gas leaves the fresh gas distributor essentially only through the respectively predetermined outlet. As a result, in the cylinders or in their combustion chambers targeted predetermined areas can be supplied with an exhaust-fresh gas mixture, while the remaining combustion chamber volume is filled essentially exclusively with fresh gas. With the help of this locally concentrated exhaust gas recirculation, the operating behavior of the internal combustion engine, in particular fuel consumption and / or pollutant emission can be positively influenced.
