Description

Die Erfindung betrifft eine Brennkraftmaschine, insbesondere für ein Kraftfahrzeug, mit einem eine Ladeluft verdichtenden Lader, welcher einen Verdichterdruckstutzen aufweist, einem Ansaugtrakt, einem den Verdichterdruckstutzen des Laders mit dem Ansaugtrakt verbindenden Ladeluftschlauch und einem im Luftstrom der Ladeluft angeordneten Geräuschdämpfer, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to an internal combustion engine, in particular for a motor vehicle, with a charge air compressing loader, which has a compressor discharge nozzle, an intake tract, the charge air hose connecting the compressor discharge port of the supercharger with the intake manifold and arranged in the air flow of the charge air silencer, according to the preamble of the claim 1.

Ein Ladeluftschlauch für eine Brennkraftmaschine dient zum Leiten von Ladeluft aus einem Lader, beispielsweise einem Abgasturbolader, direkt oder über einen Ladeluftkühler zu einem Ansaugtrakt der Brennkraftmaschine. Ein derartiger Ladeluftschlauch ist aus der DE 195 06 584 C1 bekannt und besteht aus einem flexiblen Material, um Relativbewegungen zwischen dem Lader und dem Ladeluftkühler bzw. der Brennkraftmaschine ausgleichen zu können. Der bekannte Ladeluftschlauch ist ferner mit Falten versehen, deren Außendurchmesser größer sind als der Außendurchmesser des Ladeluftschlauches. In diesen Falten ist im Inneren des Ladeluftschlauches eine ringförmige starre Einlage eingebracht, wodurch die axiale Längung des Ladeluftschlauches unter Innendruck und somit die Kräfteübertragung zwischen den Bauteilen reduziert werden soll.A charge air hose for an internal combustion engine is used to direct charge air from a supercharger, for example an exhaust gas turbocharger, directly or via a charge air cooler to an intake tract of the internal combustion engine. Such a charge air hose is known from DE 195 06 584 C1 and consists of a flexible material to compensate for relative movements between the supercharger and the intercooler or the internal combustion engine. The known charge air hose is further provided with folds whose outer diameter is greater than the outer diameter of the charge air hose. In these folds, an annular rigid insert is introduced inside the charge air hose, whereby the axial elongation of the charge air hose under internal pressure and thus the transmission of forces between the components should be reduced.

Zur Verbesserung dieses Ladeluftschlauches ist es aus der DE 199 60 427 C1 bekannt, in dem Ladeluftschlauch einstückig eine Kammer auszubilden. Diese Kammer weist einen Axialabschnitt auf, der einen größeren Innendurchmesser hat als der Ladeluftschlauch, so daß die Kammer als zusätzlicher Schalldämpfer wirkt. Die Montage eines externen Schalldämpfers kann dadurch entfallen. Als Nachteil ergibt sich jedoch die Durchmesserveränderung des Ladeluftschlauches, die einerseits einen entsprechenden Herstellungsaufwand erfordert und andererseits durch Materialermüdung eine potentielle Gefahr für einen Bruch des Ladeluftschlauches darstellt. Ferner benötigt die Durchmesserveränderung einen entsprechenden Bauraum, der zur Verfügung stehen muß.To improve this charge air hose, it is known from DE 199 60 427 C1, integrally form a chamber in the charge air hose. This chamber has an axial portion which has a larger inner diameter than the charge air hose, so that the chamber acts as an additional muffler. The installation of an external silencer can be omitted. The disadvantage, however, results in the change in diameter of the charge air hose, which on the one hand requires a corresponding production effort and on the other hand represents a potential risk of breakage of the charge air hose due to material fatigue. Furthermore, the change in diameter requires a corresponding space, which must be available.

Die Erfindung geht aus von einer Brennkraftmaschine gemäß DE 35 31 353 A1, mit einem eine Ladeluft verdichtenden Lader, welcher einen Verdichterdruckstutzen aufweist, einen Ansaugtrakt, einem den Verdichterdruckstutzen des Laders mit dem Ansaugtrakt verbindenden Ladeluftschlauch und einem im Luftstrom der Ladeluft angeordneten Geräuschdämpfer, wobei der Geräuschdämpfer in eine Kupplung zwischen Ladeluftschlauch und Verdichterdruckstutzen derart integriert ist, dass der Geräuschdämpfer einerseits in den Verdichterdruckstutzen und andererseits in den Ladeluftschlauch eingreift.The invention relates to an internal combustion engine according to DE 35 31 353 A1, with a charge air compressing supercharger, which has a compressor discharge nozzle, an intake, a compressor discharge nozzle of the supercharger with the intake connecting charge air hose and arranged in the air flow of the charge air silencer, wherein the Noise damper is integrated in a coupling between the charge air hose and the compressor pressure port such that the noise damper engages on the one hand in the compressor discharge port and on the other hand in the charge air hose.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine aufgeladene Brennkraftmaschine der obengenannten Art mit verbesserter Ladeluftzuführung zur Verfügung zu stellen.The present invention is therefore based on the object to provide a supercharged internal combustion engine of the type mentioned above with improved charge air supply available.

Diese Aufgabe wird erfindungsgemäß durch eine Brennkraftmaschine der o.g. Art mit den in Anspruch 1 gekennzeichneten Merkmalen gelöst.

Dies hat den Vorteil, dass der Geräuschdämpfer keinen zusätzlichen Bauraum benötigt und ferner gleichzeitig mit dem Anschluß des Ladeluftschlauches an den Verdichterdruckstutzen montiert ist. Femer kann auf eine sprunghafte Durchmesserveränderung des Ladeluftschlauches selbst verzichtet werden. Die erfindungsgemäße Lösung ist kleiner, leichter, kostengünstiger, wirksamer, unauffälliger.This has the advantage that the noise damper requires no additional space and is also mounted simultaneously with the connection of the charge air hose to the compressor pressure port. Furthermore, a sudden change in the diameter of the charge air hose itself can be dispensed with. The solution according to the invention is smaller, lighter, less expensive, more effective, less noticeable.
