Description

Stand der TechnikState of the art

Die Erfindung betrifft eine Saugrohranordnung für einen Verbrennungsmotor, bei der sog. Querkanäle oder Übersprecher zwischen den Saugkanälen vor den Zylindereinlässen eines mehrzylindrigen Verbrennungsmotors angeordnet sind, nach dem Oberbegriff des Hauptanspruchs.The invention relates to a suction tube arrangement for a Internal combustion engine, in the so-called. Cross channels or crosstalk between the suction channels in front of the cylinder inlets a multi-cylinder internal combustion engine are arranged, according to the preamble of the main claim.

Aus der DE 298 11 432 U1 ist ein Saugrohrsystem für einen Verbrennungsmotor bekannt, bei dem jeweils benachbarte Saugkanäle, insbesondere zur Verbesserung der akustischen Eigenschaften, solche Querverbindungen zwischen den Saugkanälen aufweisen.From DE 298 11 432 U1 is a suction pipe system for a Internal combustion engine known, in each case adjacent Suction channels, in particular to improve the acoustic Properties, such cross-connections between the suction channels exhibit.

Darüber hinaus ist es heute weitgehend üblich, dass Verbrennungsmotoren für Kraftfahrzeuge auch mit einer Abgasrückführung ausgestattet sind, da dies aufgrund weitreichender Bestimmungen für die Einhaltung von Grenzwerten bei Abgasen und aus technischen Gründen sinnvoll ist. Beispielsweise werden in der Regel Benzin- und Dieselmotoren mit Direkteinspritzung des Kraftstoffes heute schon mit einer solchen Abgasrückführung ausgestattet.In addition, today it is widely accepted that Internal combustion engines for motor vehicles also with exhaust gas recirculation are equipped, as this is due to far-reaching Provisions for compliance with limit values For exhaust gases and for technical reasons makes sense. For example, gasoline and diesel engines are usually used with direct injection of fuel today already equipped with such exhaust gas recirculation.

Es ist beispielsweise bereits aus der DE 197 17 040 C1 bekannt, dass die Abgasrückführungsleitung über eine Metallhülse an den Zylinderkopfflansch des Verbrennungsmotors angekoppelt ist. For example, it is already known from DE 197 17 040 C1 known that the exhaust gas recirculation line via a metal sleeve to the cylinder head flange of the internal combustion engine is coupled.

Problematisch ist eine Kombination dieser an sich bekannten Anordnungen jedoch in konstruktiver Hinsicht dadurch, dass mehrere Bauelemente mit einer großen Anzahl von Dichtflächen an den jeweiligen Verbindungsflanschen benötigt werden und außerdem der Wärmeeintrag und eine optimale Verteilung der Abgasrückführung relativ aufwendige und komplexe sowie bearbeitungsintensive Maßnahmen erforderlich machen.The problem is a combination of these known per se However, arrangements in a constructive way, that several components with a large number of Requires sealing surfaces on the respective connecting flanges and also the heat input and optimal Distribution of exhaust gas recirculation relatively expensive and complex and labor-intensive measures required do.
