Abstract
Description
Die Erfindung betrifft eine Abgasanlage vorzugsweise für einen Verbrennungsmotor und einen Verbrennungsmotor. The invention relates to an exhaust system, preferably for an internal combustion engine and an internal combustion engine.
Bei Kraftfahrzeugen sind Verbrennungsmotoren aktuell das weitest verbreitetste Antriebsaggregat. Auch im Hinblick auf die zunehmende Elektrifizierung im Antriebsstrang hat der Verbrennungsmotor nach wie vor ein hohes Potential, da er im Hinblick auf den Verbrauch und die Abgasemission noch weiter in Richtung Kraftstoffeffizienz und Abgasreduktion optimierbar ist. Auch ist der Verbrennungsmotor bei elektrifizierten Fahrzeugen als so genannter „range extender“ im Einsatz. In motor vehicles, internal combustion engines are currently the most widely used drive unit. Also with regard to the increasing electrification in the drive train, the internal combustion engine still has a high potential, since it can be further optimized with regard to fuel consumption and exhaust emission in the direction of fuel efficiency and exhaust gas reduction. Also, the internal combustion engine in electrified vehicles as a so-called "range extender" in use.
So weist derzeit bei Kraftfahrzeugen der Trend in Richtung kleinerer Verbrennungsmotoren mit geringerem Hubraum aber mit zum Teil dennoch hoher Leistung und hohem Drehmoment. For example, in the case of motor vehicles, there is currently a trend towards smaller internal combustion engines with a smaller displacement but in some cases high power and high torque.
Besonderer Vorteil des Verbrennungsmotors ist nach wie vor, die vielfältige Ausgestaltung im Hinblick auf die individuellen Ansprüche und Gegebenheiten. The particular advantage of the internal combustion engine is still the diverse design with regard to the individual requirements and circumstances.
Bei einem Einsatz eines Verbrennungsmotors mit reduziertem Hubraum aber dennoch hoher Leistung ist die Registeraufladung eine Option, bei welcher im Gegensatz zum Bi-Turboanordnung mit zwei Turboladern in paralleler Verschaltung, zwei Turbolader eingesetzt werden, die sich bei niedrigen Drehzahlen und abgasmengen bzw. bei hohen Drehzahlen und Abgasmengen abwechseln. When using an internal combustion engine with reduced displacement but still high performance, the register charging is an option in which, in contrast to the bi-turbo arrangement with two turbochargers in parallel connection, two turbochargers are used, which operate at low speeds and volumes of exhaust gas or at high speeds and exhaust quantities alternate.
Dabei sind derzeit Vorrichtungen von dieselangetriebenen Fahrzeugen für die Registeraufladung bekannt, wobei bei diesen herkömmliche Katalysatoren und Partikelfilter eingesetzt werden. In this case, devices of diesel-powered vehicles for register charging are currently known, in which conventional catalysts and particulate filters are used.
In der
Bei anderen Anordnungen sind jeweils nur ein Partikelfilter und ein Katalysator vorgesehen. Dies hat den Nachteil, dass der gesamte Abgasstrom immer durch den Katalysator als auch durch den Partikelfilter durchgeleitet werden muss, was zu erhöhtem Druckabfall führt, was insbesondere bei kalten Aggregaten eher ungünstig ist. In other arrangements, only one particulate filter and one catalyst are provided. This has the disadvantage that the entire exhaust stream must always be passed through the catalyst as well as through the particulate filter, which leads to increased pressure drop, which is rather unfavorable, especially in cold units.
Es ist die Aufgabe der Erfindung eine Abgasanlage und einen Verbrennungsmotor zu schaffen, welche die Nachteile des Standes der Technik verbessert und dennoch einfach aufgebaut ist. It is the object of the invention to provide an exhaust system and an internal combustion engine, which improves the disadvantages of the prior art and yet has a simple structure.
Die Aufgabe zur Abgasanlage wird erreicht mit den Merkmalen von Anspruch 1, wonach eine Abgasanlage geschaffen wird mit einer ersten Abgasleitung und einer zweiten Abgasleitung, mit einer Abgasbehandlungsanordnung, wobei die Abgasbehandlungsanordnung ein Gehäuse mit einem ersten Einlass und einen zweiten Einlass für Abgas aufweist, mit einer Filter-Katalysator-Anordnung, bei welcher der Filter und der Katalysator koaxial in dem Gehäuse angeordnet sind, wobei der erste Einlass als Rohrstutzen derart in das Gehäuse hinein ragt, dass er im mittleren Bereich der Filter-Katalysator-Anordnung, bevorzugt an diesem anliegend oder angrenzend endet, derart, dass das aus dem Rohrstutzen ausströmende Abgas im Wesentlichen im mittleren Bereich die Filter-Katalysator-Anordnung anströmt und das aus dem zweiten Einlass ausströmende Abgas im Wesentlichen in einem radial außen liegenden Ringbereich die Filter-Katalysator-Anordnung anströmt. The object of the exhaust system is achieved with the features of claim 1, according to which an exhaust system is provided with a first exhaust pipe and a second exhaust pipe, with an exhaust treatment arrangement, wherein the exhaust treatment arrangement comprises a housing having a first inlet and a second inlet for exhaust gas, with a Filter-catalyst arrangement in which the filter and the catalyst are arranged coaxially in the housing, wherein the first inlet protrudes into the housing as a pipe socket in such a way that it in the central region of the filter-catalyst assembly, preferably adjacent thereto or ends adjacent, such that the effluent from the pipe socket exhaust flows substantially in the central region of the filter-catalyst assembly and flows out of the second inlet effluent substantially in a radially outer annular region, the filter-catalyst assembly flows.
Dabei ist es besonders vorteilhaft, wenn der Rohrstutzen trichterartig aufgeweitet ist, um im Wesentlichen direkt an die Filter-Katalysatoranordnung anzugrenzen, damit möglichst kein Abgas aus dem Rohrstutzen von dem mittleren Bereich in den radial außen liegenden Ringbereich strömt oder umgekehrt. It is particularly advantageous if the pipe socket is widened in a funnel-like manner in order to be substantially directly adjacent to the filter catalyst arrangement, so that as far as possible no exhaust gas from the pipe socket flows from the central region into the radially outer annular region or vice versa.
Dies ist daher zweckmäßig, da aufgrund des höheren Abgasgegendrucks im Bereich des Filters, falls dieser im mittleren Bereich angeordnet ist, dieser nicht umgangen wird. This is therefore expedient because, due to the higher exhaust backpressure in the region of the filter, if this is arranged in the central region, this is not bypassed.
Würde der Filter radial außen angeordnet sein, so würde ein Anliegen oder Abschließen des Rohrstutzens an die Filter-Katalysatoranordnung auch das fehlgeleitete Strömen zum mittleren Bereich vorteilhaft verhindert werden. If the filter were to be arranged radially on the outside, it would also be advantageous to prevent the pipe stub from contacting or closing the filter-catalyst arrangement, and also the misdirected flow to the central area.
Vorteilhaft wird die Abgasanlage eingesetzt bei Verbrennungsmotoren, die als Ottomotoren ausgestaltet sind. Auch können solche Abgasanlagen bei Dieselmotoren eingesetzt werden. Advantageously, the exhaust system is used in internal combustion engines, which are designed as gasoline engines. Also, such exhaust systems can be used in diesel engines.
Dabei ist es besonders vorteilhaft, wenn der Filter radial innen und der Katalysator radial außen oder der Katalysator radial innen und der Filter radial außen angeordnet ist. It is particularly advantageous if the filter is arranged radially inward and the catalyst radially outward or the catalyst radially inward and the filter radially outward.
Weiterhin ist es vorteilhaft, wenn die Abgasbehandlungsanordnung abströmseitig mit einem Endschalldämpfer in Verbindung ist. Dabei kann das Abgas aus dem Katalysator und dem Filter in den Endschalldämpfer strömen und von dort aus der Abgasanlage ausströmen. Vorteilhaft sind Filter-Katalysator-Anordnung und Endschalldämpfer ineinander integriert. Furthermore, it is advantageous if the exhaust gas treatment arrangement is downstream with an end muffler in connection. In this case, the exhaust gas from the catalyst and the filter can flow into the muffler and flow out of there from the exhaust system. Advantageously, filter Catalyst arrangement and rear silencer integrated with each other.
Vorteilhaft ist es auch, wenn der Einlassbereich der Abgasbehandlungsanordnung als trichterförmiger Diffusor gestaltet ist, der einen mittigen Einlassstutzen aufweist, der den zweiten Einlass bildet. So kann das Abgas unkompliziert in die Vorrichtung einströmen. It is also advantageous if the inlet region of the exhaust gas treatment arrangement is designed as a funnel-shaped diffuser, which has a central inlet nozzle, which forms the second inlet. Thus, the exhaust gas can flow easily into the device.
Dabei ist es besonders vorteilhaft, wenn der erste Einlass durch einen Rohrstutzen gebildet ist, welcher durch die konische Wand des trichterförmigen Diffusors tritt. Dies bewirkt, dass der Abgasstrom des ersten Einlasses zentral auf die Filter-Katalysator-Anordnung einströmt. It is particularly advantageous if the first inlet is formed by a pipe socket which passes through the conical wall of the funnel-shaped diffuser. This causes the exhaust gas flow of the first inlet flows centrally on the filter-catalyst assembly.
Alternativ ist es auch vorteilhaft, wenn der Einlassbereich der Abgasbehandlungsanordnung als trichterförmiger Diffusor gestaltet ist, der einen mittigen Einlassstutzen aufweist, der bis in das Innere des Diffusors reicht und den ersten Einlass bildet. Alternatively, it is also advantageous if the inlet region of the exhaust gas treatment arrangement is designed as a funnel-shaped diffuser having a central inlet nozzle, which extends into the interior of the diffuser and forms the first inlet.
Dabei ist es auch vorteilhaft, wenn der zweite Einlass durch einen Rohrstutzen gebildet ist, welcher an die konische Wand des trichterförmigen Diffusors angeschlossen ist. It is also advantageous if the second inlet is formed by a pipe socket which is connected to the conical wall of the funnel-shaped diffuser.
Auch ist es vorteilhaft, wenn die erste Abgasleitung mit dem ersten Einlass verbunden ist und die zweite Abgasleitung mit dem zweiten Einlass verbunden ist. It is also advantageous if the first exhaust gas line is connected to the first inlet and the second exhaust gas line is connected to the second inlet.
Dabei ist es auch vorteilhaft, wenn die erste Abgasleitung mit ersten Auslassventilen einer Zylinderanordnung verbunden ist und die zweite Abgasleitung mit zweiten Auslassventilen der Zylinderanordnung verbunden ist. It is also advantageous if the first exhaust pipe is connected to first exhaust valves of a cylinder assembly and the second exhaust pipe is connected to second exhaust valves of the cylinder assembly.
Auch ist es vorteilhaft, wenn in der ersten Abgasleitung zwischen den Auslassventilen und dem ersten Einlass ein erster Abgasturbolader angeordnet bzw. verbunden ist und/oder in der zweiten Abgasleitung zwischen den Auslassventilen und dem zweiten Einlass ein zweiter Abgasturbolader angeordnet bzw. verbunden ist. It is also advantageous if a first exhaust gas turbocharger is arranged or connected in the first exhaust pipe between the exhaust valves and the first inlet and / or a second exhaust gas turbocharger is arranged or connected in the second exhaust pipe between the exhaust valves and the second inlet.
Besonders vorteilhaft ist es, wenn einer der Abgasturbolader abschaltbar ist und der entsprechend andere Abgasturbolader permanent betrieben wird. Das Abschalten wird beispielsweise dadurch erreicht, dass die Auslassventile der Abgasleitung, die zu dem abschaltbaren Abgasturbolader führen nicht geöffnet werden. It when one of the exhaust gas turbocharger is switched off and the corresponding other exhaust gas turbocharger is operated permanently is particularly advantageous. The shutdown is achieved, for example, that the exhaust valves of the exhaust pipe, which lead to the turn-off exhaust gas turbocharger not be opened.
Vorteilhaft ist es, wenn der Abgasturbolader permanent betrieben wird, der in der Abgasleitung angeordnet ist, die zu dem Filter der Filter-Katalysator-Anordnung führt. It is advantageous if the exhaust gas turbocharger is operated permanently, which is arranged in the exhaust pipe leading to the filter of the filter-catalyst assembly.
Die Aufgabe hinsichtlich des Verbrennungsmotors wird gelöst mit einem Verbrennungsmotor mit einer Mehrzahl von Zylindern, die in zumindest eine oder vorteilhaft mindestens zwei Gruppen einteilbar sind, wobei eine oben beschriebene Abgasanlage pro Gruppe vorgesehen ist. The object with regard to the internal combustion engine is achieved with an internal combustion engine having a plurality of cylinders, which can be divided into at least one or advantageously at least two groups, with one exhaust system per group described above being provided.
Weitere vorteilhafte Ausgestaltungen sind durch die nachfolgende Figurenbeschreibung und durch die Unteransprüche beschrieben. Further advantageous embodiments are described by the following description of the figures and by the subclaims.
