Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Zuführen eines Hilfsmittels zu einer Abgasnachbehandlungseinrichtung eines Kraftfahrzeugs, insbesondere eine solche Vorrichtung nach dem Oberbegriff des Anspruchs 1.The The invention relates to a device for feeding a Aid to an exhaust aftertreatment device of a motor vehicle, in particular, such a device according to the preamble of the claim 1.
Bei Brennkraftmaschinen existieren immer strengere Grenzwerte für die Abgase, weshalb die Brennkraftmaschinen üblicherweise mit immer effektiveren Abgasnachbehandlungseinrichtungen gekoppelt werden. Diese Abgasnachbehandlungseinrichtungen benötigen im Allgemeinen Hilfsmittel für verschiedene chemische Reaktionen mit den Abgasen der Brennkraftmaschine. Zum Beispiel wird bei dieselbetriebenen Brennkraftmaschinen zur Reduzierung des Stickoxidanteils im Abgasstrom eine selektive katalytische Reduktion (SCR) durchgeführt, bei welcher die Stickoxide (NOx) mit Hilfe von Reduktionsmitteln wie beispielsweise einer Harnstoff-Wasser-Lösung (HWL) zu unschädlichem Stickstoff und Wasser(dampf) reduziert werden.In internal combustion engines, stricter limit values for the exhaust gases exist, which is why the internal combustion engines are usually coupled with increasingly effective exhaust aftertreatment devices. These exhaust aftertreatment devices generally require auxiliaries for various chemical reactions with the exhaust gases of the internal combustion engine. For example, in the case of diesel-operated internal combustion engines, a selective catalytic reduction (SCR) is carried out to reduce the nitrogen oxide fraction in the exhaust gas stream, with the nitrogen oxides (NO x ) being converted into harmless nitrogen and water by means of reducing agents, such as, for example, a urea-water solution (HWL). steam) can be reduced.
