Description
Die Erfindung betrifft Komponenten für Abgasanlagen für Verbrennungsmotoren, insbesondere für Dieselmotoren, gemäß dem Oberbegriff des Anspruchs 1.The The invention relates to components for Exhaust systems for Internal combustion engines, in particular for diesel engines, according to the preamble of claim 1.
Abgasanlagen für Verbrennungsmotoren, gleichgültig ob Otto- oder Dieselmotoren, werden seit über 100 Jahren in größten Stückzahlen und in den unterschiedlichsten Ausführungen produziert und eingesetzt. Ihre ursprüngliche Aufgabe bestand darin, den vom Verbrennungsmotor erzeugten Lärm auf ein verträgliches, später vom Gesetzgeber vorgeschriebenes Maß zu reduzieren. In den letzten 40 Jahren kam zusätzlich die Aufgabe dazu, die in den Abgasen enthaltenen Schadstoffe wie CO, NOx, Ruß usw. zu beseitigen. Moderne Abgasanlagen enthalten daher je nach Verwendungszweck eine Dieselrußpartikelfilter(DPF)-Einheit, eine selektiv katalytische Reduktions(SCR)-Einheit und/oder eine Dieseloxidationskatalysator(DOC)-Einheit, oder auch eine einfache Katalysatoreinheit.Exhaust systems for internal combustion engines, regardless of whether petrol or diesel engines, have been produced and used for over 100 years in the largest quantities and in a wide variety of designs. Their original task was to reduce the noise generated by the internal combustion engine to a tolerable, later prescribed by law. In the last 40 years, the additional task was to eliminate the pollutants contained in the exhaust gases, such as CO, NO x , soot, etc. Modern exhaust systems therefore include, depending on the application, a diesel particulate filter (DPF) unit, a selective catalytic reduction (SCR) unit and / or a diesel oxidation catalyst (DOC) unit, or even a simple catalyst unit.
Als Träger für die erwähnten Einheiten zur Reduzierung und/oder Reinigung der Verbrennungsabgase kommen keramische oder metallische Trägerelemente zum Einsatz. Keramische Trägerelemente müssen aufgrund der Tatsache, dass ihr thermischer Ausdehnungskoeffizient sich deutlich von den thermischen Ausdehnungskoeffizienten der Metallteile der Abgasanlagen unterscheiden, mit Hilfe von Lagermatten, Quellmatten und dergleichen aufwändig gelagert werden. Darüber hinaus lassen sich die keramischen Elemente nur mit relativ großen Abmessungstoleranzen produzieren, so dass die sie aufnehmenden Gehäuse oftmals aufwändig kalibriert werden müssen.When carrier for the mentioned Units for reducing and / or purifying the combustion gases ceramic or metallic carrier elements are used. ceramic Carrier elements must be due the fact that their thermal expansion coefficient is distinct from the thermal expansion coefficients of the metal parts of the exhaust systems distinguish with the help of bearing mats, swelling mats and the like costly be stored. About that In addition, the ceramic elements can only with relatively large dimensional tolerances produce, so that the accommodating housing often be laboriously calibrated have to.
Ein weiterer Problempunkt bei der Produktion von Abgasanlagen ist die Tatsache, dass die vorgefertigten aktiven Komponenten in die ebenfalls vorgefertigten Gehäuse eingeführt werden müssen, wobei während der Montage bestimmte Presskräfte eingehalten werden müssen, um zu verhindern, dass die Einsätze entweder ihren Halt verlieren oder beschädigt werden, wenn sich die Abgasanlage im Betrieb auf Temperaturen bis zu 900°C erhitzt.One Another problem in the production of exhaust systems is the Fact that the prefabricated active components in the likewise prefabricated housing introduced Need to become, while during the assembly certain pressing forces must be respected to prevent the stakes either lose their grip or be damaged when the Exhaust system in operation to temperatures up to 900 ° C heated.
Ein weiteres Problem der klassischen Produktion von Abgasanlagen ist darin begründet, dass die jeweiligen Einbaukomponenten oftmals nur in vorbestimmten Formen und Abmessungen produziert werden können. Das gilt nicht nur für die keramischen sondern auch für die metallischen Einbaukomponenten. Dadurch können die Vorgaben der Kraftfahrzeughersteller oftmals nicht oder nur annähernd erfüllt werden, was beim Bau der Kraftfahrzeuge zu Kompromissen Anlass gibt.One Another problem is the classic production of exhaust systems founded in that the respective installation components often only in predetermined Shapes and dimensions can be produced. This is not only true for the ceramic for .... As well the metallic components. This allows the specifications of the motor vehicle manufacturer often not or only approximately fulfilled, which gives rise to compromises in the construction of motor vehicles.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, Komponenten für Abgasanlagen für Verbrennungsmotoren, insbesondere für Dieselmotoren, in Kraftfahrzeugen anzugeben, die eine praktisch beliebige Formgebung und damit verbunden Abgasführung ermöglichen.Of the The present invention is based on the object, components for exhaust systems for internal combustion engines, especially for Diesel engines, in motor vehicles indicate that a practical allow any shape and associated exhaust system.
Diese Aufgabe wird gelöst durch Komponenten mit den Merkmalen des Anspruchs 1.These Task is solved by components having the features of claim 1.
Die vorliegende Erfindung ersetzt die bisher verwendeten vorgefertigten Einbaukomponenten auf Keramikbasis oder auch Metallblechbasis durch einen metallischen Schaumwerkstoff. Dadurch entfällt das Stopfen von vorgefertigten Elementen in die Gehäuse und das Lagern der vorgefertigten Komponenten mit Hilfe von Lager- und Quellmatten. Struktur und Porengröße des Schaums lassen sich in weiten Grenzen an die vorgegebenen Bedingungen anpassen.The The present invention replaces the previously used prefabricated ones Built-in components based on ceramic or sheet metal base a metallic foam material. This eliminates the need to stop prefabricated Elements in the housing and storing the prefabricated components by means of storage and swelling mats. Structure and pore size of the foam can be within wide limits to the given conditions.
Ferner kann der Schaumwerkstoff entsprechend dem gewünschten Einsatzzweck mit den entsprechenden Elementen katalytisch beschichtet werden, um so die Funktion als Kat-Einheit, SCR-Einheit, DOC-Einheit oder DPF-Einheit zu erfüllen.Further the foam material according to the desired application with the corresponding elements are catalytically coated so as to Function as cat unit, SCR unit, DOC unit or DPF unit.
Das Grundprinzip der Erfindung ist, dass die im Abgassystem integrierten Komponenten um wenigstens ein Einlass- und/oder Auslassrohr als Schaum-Kartusche angeordnet sind. Die Rohre sind optimal perforiert, um eine gleichmäßige Durchströmung der Schaumkomponenten mit Abgasen zu ermöglichen. Dabei können die Rohre auch gleichzeitig die Tragfunktion übernehmen.The The basic principle of the invention is that the integrated in the exhaust system Components around at least one inlet and / or outlet tube as a foam cartridge are arranged. The tubes are optimally perforated to ensure a uniform flow through the To allow foam components with exhaust gases. The can Pipes also take over the supporting function at the same time.
Die Schaumkörper werden durch ringförmige Distanzelemente auf Position gehalten, die sich wiederum an metallischen und am Zentralrohr befestigten Anlaufscheiben abstützen.The foam body be through annular spacers held in position, which in turn to metallic and am Support central pipe mounted thrust washers.
Gemäß einer bevorzugten Ausgestaltung der Erfindung kann das sich so ergebende zylinderförmige Schaumgebilde, beispielsweise die Hintereinanderschaltung von DOC-Einheit und DPF-Einheit, durch ein Rohr in definiertem Abstand umfasst sein, so dass ein Ringspalt als Kanal zur Wegführung der Abgase entsteht. In diesen Ringspalt kann die zur katalytischen Reduktion benötigte Harnstoff-Wasser-Lösung eingedüst werden.According to one preferred embodiment of the invention, the thus resulting cylindrical Foam structures, for example, the series connection of DOC unit and DPF unit through a pipe at a defined distance, so that an annular gap as a channel for guidance the exhaust gas is produced. In this annular gap, the catalytic Reduction needed Urea-water solution injected become.
Vorteilhafterweise sitzt die Harnstoffdüse am Eingang des Kanals.advantageously, sits the urea nozzle at the entrance of the canal.
Da zur Verdampfung der Harnstoff-Wasser-Lösung eine möglichst lange Verdampfungsstrecke benötigt wird, abhängig von Temperatur, Tröpfchengröße und Massenstrom, wird in den erwähnten Kanal ein wendelförmiges Gasleitblech eingesetzt. Dadurch wird das Gas schraubenförmig durch den Wendelkanal geführt, wodurch der zur Verfügung stehende Verdampfungsweg vervielfacht wird, je nach Steigung des Wendelblechs. Diese schraubenförmige Abgasführung stellt gleichzeitig eine akustische Tuningmaßnahme dar, so dass eine gestalterische Freiheit für die Anpassung von zur Schalldämpfung erforderlichen Rohrlängen vorhanden ist.Since the evaporation of the urea-water solution as long as possible evaporation path is required, depending on temperature, droplet size and mass flow, a helical gas baffle is used in the mentioned channel. As a result, the gas is helically through the Spiral channel out, whereby the available evaporation path is multiplied, depending on the pitch of the spiral sheet. At the same time, this helical exhaust gas duct represents an acoustic tuning measure, so that there is freedom of design for the adaptation of pipe lengths required for soundproofing.
Anhand der Zeichnung soll die Erfindung in Form eines Ausführungsbeispiels näher erläutert werden.Based the drawing is intended to illustrate the invention in the form of an embodiment be explained in more detail.
