Abstract
Description
Die Erfindung betrifft eine Abgasanlage gemäß dem Oberbegriff des Anspruchs 1.The The invention relates to an exhaust system according to Preamble of claim 1.
Aus
der
Es ist Aufgabe der vorliegenden Erfindung, eine Abgasanlage der eingangs genannten Art zu schaffen, mit deren Hilfe eine Temperatur in unmittelbarer Nähe des Rohrendes eines Abgasrohrs verringert werden können.It Object of the present invention, an exhaust system of the above to create said type, with the help of which a temperature in the immediate Can be reduced near the pipe end of an exhaust pipe.
Zur Lösung der Aufgabe wird eine Abgasanlage für eine Brennkraftmaschine mit den Merkmalen des Anspruchs 1 vorgeschlagen. Die Abgasanlage umfasst ein Abgasrohr mit mindestens einer an dessen Mantel vorgesehenen, seitlichen Abgasaustrittsöffnung. Das Abgasrohr zeichnet sich dadurch aus, dass es an seinem der Brennkraftmaschine abgewandten Rohrende zumindest teilweise verschlossen ist. Dies kann beispielsweise mittels eines Deckels realisiert werden, welcher das Rohrende ganz oder – in Form einer Lochblende – teilweise verschließt. Ein für einen Abgasaustritt am Rohrende nutzbarer, freier Durchtrittsquerschnitt des Abgasrohrs wird dadurch zumindest verringert. Ein im Innern des Abgasrohrs resultierender Staudruck ist nutzbar, um einen Mengenanteil eines durch die mindestens eine seitliche Austrittsöffnung ausströmenden Abgases zu erhöhen. Ein wesentlicher Vorteil besteht darin, dass eine Temperatur am Rohrende reduzierbar ist. Eine Aufteilung eines Abgasstroms auf mehrere, kleinere Austrittsöffnungen ermöglicht eine rasche Auffächerung, Verwirbelung und Vermischung mit der kühleren Umgebungsluft, was wiederum angrenzende Bauteile vor einer schädlichen Erhitzung schützt.to Solution of the task is an exhaust system for a Internal combustion engine proposed with the features of claim 1. The exhaust system comprises an exhaust pipe with at least one at the Sheath provided, lateral exhaust gas outlet. The exhaust pipe is characterized by the fact that it is at its internal combustion engine remote pipe end is at least partially closed. This can be realized for example by means of a lid, which the pipe end completely or - in the form of a pinhole - partially closes. One for an exhaust gas outlet at the pipe end usable, free passage cross-section of the exhaust pipe is thereby at least reduced. A resulting in the interior of the exhaust pipe back pressure is useful to a proportion of a through the at least one lateral outlet opening effluent exhaust gas to increase. A significant advantage is that a temperature at the pipe end can be reduced. A division of one Exhaust gas flow to several, smaller outlet openings allows a fast fanning, turbulence and mixing with the cooler ambient air, which in turn is adjacent components protects against harmful heating.
Darüber hinaus ist mit Hilfe des teilweises oder vollständig verschlossenen Rohrendes ein Schutz gegen ein Eindringen von Schmutz, Spritz- oder Regenwasser in das Abgasrohr erreichbar, insbesondere dann, wenn das Rohrende nach oben weist.About that In addition, with the help of the partially or completely closed Pipe end a protection against ingress of dirt, spray or Rainwater in the exhaust pipe reachable, especially if the pipe end points upwards.
Bei einem vorteilhaften Ausführungsbeispiel der Abgasanlage sind mehrere seitliche Abgasaustrittsöffnungen vorgesehen sind, welche in Längsrichtung des Abgasrohres gesehen hintereinander angeordnet. Diese Ausgestaltung ist insbesondere dann vorteilhaft, wenn beispielsweise aufgrund von zum Abgasrohr benachbart angeordneter, hitzeempfindlicher Bauteile nur ein begrenzter, sich über einen Längenabschnitt des Abgasrohres erstreckender Winkelbereich für eine Abführung des Abgases verfügbar ist. Gegenüber einer einzigen, relativ langen, schlitzförmigen Abgasaustrittsöffnung in Längsrichtung des Abgasrohrs ermöglichen mehrere, hintereinander liegende und durch Stege getrennte Abgasaustrittsöffnungen eine höhere Stabilität des Abgasrohres. Die Stege verbessern zudem die Auffächerung, Verwirbelung und Vermischung des Abgasstroms mit der kühleren Umgebungsluft.at an advantageous embodiment of the exhaust system are provided more lateral exhaust gas outlet openings are, which in the longitudinal direction of the exhaust pipe seen one behind the other arranged. This embodiment is particularly advantageous if, for example, due to being arranged adjacent to the exhaust pipe, heat-sensitive components only a limited, over a length portion of the exhaust pipe extending angle range is available for a discharge of the exhaust gas. Opposite a single, relatively long, slit-shaped Exhaust outlet opening in the longitudinal direction of the exhaust pipe allow multiple, consecutive and through Webs separate exhaust gas outlet openings a higher Stability of the exhaust pipe. The bars also improve the fanning, turbulence and mixing of the exhaust stream with the cooler ambient air.
Gemäß einer weiteren vorteilhaften Ausführungsform der Abgasanlage ist die mindestens eine seitliche Abgasaustrittsöffnung unmittelbar benachbart zum Rohrende vorgesehen. Bei vollständig verschossenem Rohrende wird auf diese Weise ein zwischen der Abgasaustrittsöffnung und dem Rohrende verbleibender, ungenutzter Endabschnitt des Abgasrohres auf eine minimale Länge reduziert.According to one further advantageous embodiment of the exhaust system is the at least one lateral exhaust gas outlet opening provided immediately adjacent to the pipe end. At complete verschossenem pipe end is in this way between the exhaust gas outlet opening and the pipe end remaining, unused end portion of the exhaust pipe reduced to a minimum length.
Zur Lösung der Aufgabe wird ferner ein Kraftfahrzeug mit einer Abgasanlage mit den Merkmalen gemäß einem der Ansprüche 1 bis 3 vorgeschlagen.to Solution of the problem is also a motor vehicle with a Exhaust system with the features according to one of Claims 1 to 3 proposed.
Bei einer vorteilhaften Weiterbildung des erfindungsgemäßen Kraftfahrzeugs ist vorgesehen, dass das Abgasrohr in Einbaulage so angeordnet ist, dass ein aus der seitlichen Abgasaustrittsöffnung austretender Abgasstrom von benachbarten Bauteilen des Kraftfahrzeugs weggerichtet ist. Dies kann beispielsweise dadurch realisiert werden, dass die Abgasaustrittsöffnung des an dem Kraftfahrzeug angebauten Abgasrohrs von hitzeempfindlichen Aufbauten und/oder Karosserieteilen wegweist. Diese Ausgestaltung kann teure, beispielsweise bauliche Maßnahmen zur Verhinderung von Hitzeschäden am Kraftfahrzeug durch austretende Abgase erübrigen.at an advantageous development of the invention Motor vehicle is provided that the exhaust pipe in installation position is arranged so that an emerging from the side exhaust gas outlet opening Exhaust gas stream directed away from adjacent components of the motor vehicle is. This can be realized, for example, in that the exhaust gas outlet opening of the mounted on the motor vehicle exhaust pipe of heat sensitive Bodies and / or body parts wegweisen. This embodiment can expensive, for example, structural measures to prevent of heat damage to the motor vehicle by exiting exhaust gases unnecessary.
Eine weitere vorteilhafte Ausgestaltung des Kraftfahrzeugs besteht darin, dass das Rohrende zumindest im Wesentlichen senkrecht nach oben weisend in einem an eine Fahrerkabine angrenzenden Bereich angeordnet ist. Das Abgasrohr kann beispielsweise rückwärtig oder seitlich so an der Fahrerkabine positioniert sein, dass die Abgasaustrittsöffnung im oberen Bereich der Fahrerkabine oder höher liegt. Auf diese Weise kann verhindert werden, dass die austretenden Abgase in die unmittelbare Nähe von Personen geleitet werden. Das heiße Abgas kann nach oben entweichen und sich dort mit der kühleren Umgebungsluft vermischen.A further advantageous embodiment of the motor vehicle is to that the tube end at least substantially vertically upwards arranged facing in a region adjacent to a driver's cab is. The exhaust pipe can, for example, the rear or laterally be positioned on the driver's cab such that the Exhaust outlet in the upper area of the driver's cab or higher. In this way it can be prevented that the exiting exhaust gases in the immediate vicinity of Persons are guided. The hot exhaust gas can go up escape and there with the cooler ambient air mix.
Weitere vorteilhafte Ausgestaltungen der Abgasanlage und des Kraftfahrzeugs ergeben sich aus Kombinationen der aus den Unteransprüchen, der Zeichnung sowie der zugehörigen Figurenbeschreibung hervorgehenden Merkmale.Further advantageous embodiments of the exhaust system and the motor vehicle result from combinations of the subclaims, the drawing and the associated figure description resulting features.
