Description
Die Erfindung betrifft eine Abgasstranganordnung für ein, insbesondere landwirtschaftliches, Fahrzeug gemäß Oberbegriff des Anspruchs 1.The invention relates to an exhaust gas arrangement for a, in particular agricultural, vehicle according to the preamble of claim 1.
Fahrzeuge wie Traktoren oder selbstfahrende Erntemaschinen sind üblicherweise mit einem Verbrennungsmotor ausgestattet, der zur Bereitstellung von Leistung für den Fahrantrieb und weitere Funktionen dient. Als Verbrennungsmotor kommt dabei üblicherweise ein Dieselmotor zum Einsatz, dessen Abgase über einen Abgasstrang, welcher eine Mehrzahl an Komponenten aufweist, von dem Verbrennungsmotor in die Umgebung geleitet werden und die eine Reihe von Schadstoffen enthalten. Um den Ausstoß an Schadstoffen zu verringern, werden bei modernen Fahrzeugen die Abgase durch Vorrichtungen zur Abgasnachbehandlung gereinigt, bevor sie an die Umgebung abgegeben werden, wobei die Abgasnachbehandlung in den Abgasstrang integriert und dessen Bestandteil ist. Die Abgasnachbehandlung erfolgt üblicherweise in mehreren Schritten und mittels unterschiedlicher Komponenten des Abgasstranges und wird durch eine Vielzahl an Sensoren und Sensoreinrichtungen überwacht, gesteuert und geregelt. Die Abgase können beispielsweise nach einem ersten Oxidationskatalysator durch einen Diesel-Partikelfilter (DPF) zur Verringerung der Anzahl an Partikeln in den Abgasen geleitet werden. Weiterhin kann eine in den Abgasen enthaltene Konzentration von Stickoxiden (NOx) durch eine selektive katalytische Reduktion (SCR) in einem entsprechenden Katalysator reduziert werden. Dazu wird den Abgasen eine unmittelbar reduzierend wirkende Substanz, beispielsweise eine Harnstoff-Lösung, zugeführt, welche erst im Abgas die benötigten reduzierenden Substanzen freisetzt. Die eigentliche selektive katalytische Reduktion findet dabei in einem sogenannten SCR-Katalysator stromabwärts der Harnstoff-Dosierung statt.Vehicles such as tractors or self-propelled harvesters are usually equipped with an internal combustion engine that provides power to the propulsion system and other functions. As a combustion engine, a diesel engine is usually used, the exhaust gases are passed through an exhaust line, which has a plurality of components, from the engine into the environment and containing a number of pollutants. In order to reduce the emission of pollutants, in modern vehicles, the exhaust gases are cleaned by exhaust after-treatment devices before they are released into the environment, the exhaust aftertreatment integrated into the exhaust line and is part of it. The exhaust aftertreatment is usually carried out in several steps and by means of different components of the exhaust system and is monitored, controlled and regulated by a variety of sensors and sensor devices. For example, after a first oxidation catalyst, the exhaust gases may be passed through a diesel particulate filter (DPF) to reduce the number of particulates in the exhaust gases. Furthermore, a concentration of nitrogen oxides (NOx) contained in the exhaust gases can be reduced by a selective catalytic reduction (SCR) in a corresponding catalyst. For this purpose, the exhaust gases an immediate reducing substance, for example, a urea solution, fed, which releases the required reducing substances only in the exhaust gas. The actual selective catalytic reduction takes place in a so-called SCR catalyst downstream of the urea dosing.
Diese aufwändige Nachbehandlung der Abgase hat zur Folge, dass der Abgasstrang durch eine zunehmende Anzahl an Komponenten komplexer wird und für die Installation der Komponenten mehr Bauraum benötigt wird. Eine verbesserte Nutzung des Bauraumes ist beispielsweise aus der
