Description
Die Erfindung betrifft eine Abgasnachbehandlungseinrichtung für Dieselmotoren von Fahrzeugen, vorzugsweise von PKWs, nach dem Oberbegriff des Anspruches 1.The The invention relates to an exhaust aftertreatment device for diesel engines of vehicles, preferably of passenger cars, according to the preamble of Claim 1.
Solche Abgasnachbehandlungseinrichtungen werden hauptsächlich in Lastkraftwagen eingesetzt, um die von den Dieselmotoren erzeugten Abgase so zu behandeln, daß die Stickoxide (NO, NO2) zumindest teilweise gebunden werden. Hierzu ist eine Pumpe vorgesehen, die eine 32,5 %-ige Harnstoff-Wasser-Lösung als Abgasnachbehandlungsmedium aus einem Vorratstank fördert und unter einem bestimmten Druck dem Einspritzventil zuführt. Es dosiert die benötigte Menge an Harnstoff-Wasser-Lösung in einen druckgeregelten Luftstrom ein. Er wird bei LKWs dem Fahrzeugbordnetz entnommen. Für einen PKW muß die Druckluft über einen gesonderten Luftkompressor bereitgestellt werden. Der Luftstrom reißt die eingespritzte Harnstoff-Wasser-Lösung mit. Die auf diese Weise entstehende Emulsion wird über eine Aerosolleitung zur Einspritzdüse am Abgasrohr geführt und dort vor dem Katalysator in das Abgasrohr eingedüst. Die Steuerung, die verschiedenen Sensoren, die Einspritzdüse am Abgasrohr oder die Pumpen liegen räumlich zum Teil weit auseinander. Darum müssen diese einzelnen Komponenten über einen Kabelbaum verknüpft und die Kabel zu allen diesen Komponenten gezogen werden. Häufig müssen die Kabel hierbei in der Nähe des Auspuffes verlegt werden, wo hohe Temperaturen herrschen.Such exhaust aftertreatment devices are mainly used in trucks to treat the exhaust gases generated by the diesel engines so that the nitrogen oxides (NO, NO 2 ) are at least partially bonded. For this purpose, a pump is provided which conveys a 32.5% urea-water solution as an exhaust gas aftertreatment medium from a storage tank and supplies under a certain pressure to the injection valve. It meters the required amount of urea-water solution into a pressure-controlled airflow. It is taken from the vehicle electrical system in trucks. For a car, the compressed air must be provided via a separate air compressor. The air stream entrains the injected urea-water solution. The resulting emulsion is passed through an aerosol line to the injection nozzle on the exhaust pipe and injected there before the catalyst in the exhaust pipe. The controller, the various sensors, the injection nozzle on the exhaust pipe or the pumps are spatially far apart. Therefore, these individual components must be linked via a wiring harness and the cables must be pulled to all these components. Often, the cables must be routed near the exhaust where high temperatures prevail.
Der Erfindung liegt die Aufgabe zugrunde, die gattungsgemäße Abgasnachbehandlungseinrichtung so auszubilden, daß sie bei einfachem Aufbau einfach in das Fahrzeug eingebaut werden kann.Of the Invention is based on the object, the generic exhaust aftertreatment device to train them can be easily installed in the vehicle with a simple structure.
Diese Aufgabe wird bei der gattungsgemäßen Abgasnachbehandlungseinrichtung erfindungsgemäß mit den kennzeichnenden Merkmalen des Anspruches 1 gelöst.These Task is in the generic exhaust aftertreatment device according to the invention with the characterizing features of claim 1 solved.
Bei der erfindungsgemäßen Abgasnachbehandlungseinrichtung sind zumindest die Pumpe und die Steuerung zu einer Einbaueinheit zusammengefaßt. Das aufwendige Verlegen von Kabeln zwischen diesen Komponenten kann dadurch entfallen, so daß die Einrichtung einfach eingebaut werden kann.at the exhaust gas aftertreatment device according to the invention are at least the pump and the controller to a mounting unit summarized. The time-consuming laying of cables between these components can thereby omitted, so that the Device can be easily installed.
Weitere Merkmale der Erfindung ergeben sich aus den weiteren Ansprüchen, der Beschreibung und der Zeichnung.Further Features of the invention will become apparent from the other claims, the Description and the drawing.
Die Erfindung wird anhand eines in der Zeichnung dargestellten Ausführungsbeispieles näher erläutert. Die Zeichnung zeigt eine erfindungsgemäße Abgasnachbehandlungseinrichtung in schematischer Darstellung.The The invention will be described with reference to an embodiment shown in the drawing explained in more detail. The Drawing shows an exhaust aftertreatment device according to the invention in a schematic representation.
