Abstract
Bei einer Abgasanlage ist stromauf eines Endschalldämpfers ein Abgas-Ausgangsrohr mit Öffnungen versehen, die in die Umgebungsluft einmünden. Mit diesem Abgas-Ausgangsrohr sind Abgas-Endrohre verbunden.In an exhaust system, upstream of a rear silencer, an exhaust gas outlet pipe is provided with openings that open into the ambient air. Exhaust tailpipes are connected to this exhaust outlet pipe.
Description
Die Erfindung bezieht sich auf eine Abgasanlage nach dem Oberbegriff des Anspruchs 1.The The invention relates to an exhaust system according to the preamble of claim 1.
Aus
der
Aufgabe der Erfindung ist es, eine Abgasanlage für ein Kraftfahrzeug zu schaffen, mit dem ein definiertes Geräuschverhalten hinsichtlich austretender Abgase erzielbar ist.task the invention is to provide an exhaust system for a motor vehicle, with a defined noise behavior is achievable with respect to exiting exhaust gases.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst. Weitere vorteilhafte Merkmale beinhalten die Unteransprüche.These The object is achieved by the Characteristics of claim 1 solved. Further advantageous features include the subclaims.
Die mit der Erfindung hauptsächlich erzielten Vorteile bestehen darin, dass eine Reduzierung der Einzelfrequenz am Abgas-Endrohr und in Abhängigkeit hiervon eine erhebliche Reduzierung eines Geräuschpegels des Fahrzeugs erzielbar ist. Dies wird nach der Erfindung dadurch erreicht, indem im Abgas-Ausgangsrohr Öffnungen kreisringförmig angeordnet sind, die unmittelbar nach außen in die Umgebungsluft ausmünden. Vorteilhafterweise sind die Öffnungen kreisförmig als Schlitz oder polygonal ausgeführt, wobei die Öffnungen unmittelbar vor einer Verbindung des Abgas-Endrohres mit dem Abgas-Ausgangsrohr angeordnet sind.The with the invention mainly The advantages achieved are that a reduction in the individual frequency at the exhaust tailpipe and depending From this a significant reduction of a noise level of the vehicle can be achieved is. This is achieved according to the invention by openings in the exhaust gas outlet pipe circular ring are arranged, which open out immediately into the ambient air. advantageously, are the openings circular designed as a slot or polygonal, with the openings immediately before a connection of the exhaust tailpipe with the exhaust gas outlet pipe are arranged.
Eine Abstimmung der Einzelfrequenz und somit des Gesamtgeräuschpegels kann definiert erfolgen, indem nach der Erfindung die Lage und Anzahl der Öffnungen im Abgas-Ausgangsrohr, deren Öffnungsquerschnitt sowie die geometrische Ausbildung der Öffnungen entsprechend ausgeführt wird.A Tuning of the single frequency and thus of the overall noise level can be defined by, according to the invention, the location and number the openings in the exhaust gas outlet pipe, whose opening cross-section as well as the geometric design of the openings is carried out accordingly.
Die Öffnungen oder auch Perforationen im Abgas-Ausgangsrohr können nach der Erfindung z.B. durch Edelstahlwolle oder sonst wie durch isolierendes/absorbierendes Material abgedeckt sein. Dadurch wird sowohl ein zusätzlicher Abstimmungsparameter als auch eine Abdichtung des Abgas-Ausgangsrohres gegenüber einem Gasaustritt erzielt. Die Edelstahlwolle oder das isolierende/absorbierende Material kann das Abgas-Ausgangsrohr ummanteln.The openings or also perforations in the exhaust gas outlet pipe according to the invention can e.g. by stainless steel wool or otherwise by insulating / absorbing Covered material. This will be both an additional Adjustment parameters as well as a seal of the exhaust gas outlet pipe across from achieved a gas leak. The stainless steel wool or the insulating / absorbent Material can encase the exhaust outlet pipe.
Die Öffnungen können in allen möglichen Formen und Anzahl eingebracht werden. Auch Kombinationen verschiedener Formen sind möglich. Hierdurch ist eine Abstimmung der Wirkung und des Geräuscheindrucks außerhalb (Außengeräusch) und innerhalb (Innengeräusch/Sound) erreichbar.The openings can in all possible forms and number are introduced. Also combinations of different Shapes are possible. This is a vote of the effect and the sound impression outside (Outside noise) and inside (interior noise / sound) reachable.
Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen dargestellt und wird im Folgenden näher beschrieben.One embodiment The invention is illustrated in the drawings and will be described in more detail below.
