Nachteilig bei dem bekannten Stand der Technik ist, dass das der Verbrennungskraftmaschine nach dem Partikelfilter zurückgeführte Abgas trotz des Partikelfilters teilweise noch mit Partikeln beladen ist. Bei Zuführung der rückgeführten Abgase vor dem Verdichter des Abgasturboladers kommt es zu Ablagerungen der Partikel an den Schaufeln des Verdichters. Diese Partikelablagerungen führen zu einer Beeinträchtigung der Leistung des Abgasturboladers und somit zu einer Verringerung des Wirkungsgrades der Brennkraftmaschine. Die Zuführung des Abgases nach dem Verdichter beeinträchtigt eine regelbare Zuführung des rückgeführten Abgases.adversely in the known prior art, that of the internal combustion engine exhaust gas recirculated to the particulate filter partially laden with particles despite the particle filter. At feeder the recirculated exhaust gases Before the compressor of the exhaust gas turbocharger deposits occur the particles on the blades of the compressor. These particle deposits to lead to an impairment the performance of the exhaust gas turbocharger and thus to a reduction the efficiency of the internal combustion engine. The feeder of the Exhaust gas after the compressor affects a controllable supply of the recirculated exhaust gas.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine dazugehörige Vorrichtung zum Betreiben einer Verbrennungskraftmaschine zu schaffen, bei dem bei einem geringen Schadstoffanteil im Abgas die Partikelbelastung des der Brennkraftmaschine rückgeführten Abgases reduziert und der Wirkungsgrad der Brennkraftmaschine weiter verbessert wird.Of the Invention is based on the object, a method and an associated apparatus for To operate an internal combustion engine, in which at a low pollutant content in the exhaust gas the particle load of the the internal combustion engine recirculated exhaust gas reduced and the efficiency of the internal combustion engine further improved becomes.
Diese Aufgabe wird entsprechend dem gattungsgemäßen Verfahren erfindungsgemäß durch die kennzeichnenden Merkmale des Patentanspruches 1 und entsprechend der gattungsgemäßen Vorrichtung erfindungsgemäß durch die kennzeichnenden Merkmale des Patentanspruches 6 gelöst.These Task is according to the generic method according to the invention by the characterizing features of claim 1 and corresponding the generic device according to the invention solved the characterizing features of claim 6.
Erfindungsgemäß wird das der Brennkraftmaschine zurückgeführte Abgas, das vorher einen Partikelfilter zur Abgasreinigung durchlaufen hat, vor Zuführung eines in einer Verbrennungsluftleitung angeordneten Verdichters eines Abgasturboladers durch einen Abscheider gereinigt. In dem Abscheider, der vorzugsweise als Zyklonabscheider ausgebildet ist, werden die im Abgas noch vorhandenen Restpartikel abgeschieden, so dass nahezu partikelfreies Abgas der Brennkraftmaschine mit der Frischluft als Verbrennungsluft zugeführt wird. Der Abscheider ist in der Abgasrückführungsleitung angeordnet, die die Abgasleitung nach dem Partikelfilter mit der Saugleitung für die Frischluft vor dem Verdichter des Abgasturboladers verbindet.According to the invention the internal combustion engine recirculated exhaust gas, that has previously undergone a particulate filter for exhaust gas purification, before feeder a arranged in a combustion air duct compressor an exhaust gas turbocharger cleaned by a separator. By doing Separator, which is preferably designed as a cyclone separator, the remaining particles remaining in the exhaust gas are separated, so that almost particle-free exhaust gas of the internal combustion engine with the Fresh air is supplied as combustion air. The separator is in the exhaust gas recirculation line arranged, which the exhaust pipe after the particle filter with the suction line for the Fresh air in front of the compressor of the turbocharger connects.
Durch die Anordnung eines Ventils in der Abgasleitung nach der Abzweigung der Abgasrückführungsleitung wird die rückgeführte Abgasmenge regelbar eingestellt. Außerdem kann durch Regelung des Ventils im Partikelfilter ein Druckstoß durch die Abgase erzeugt werden, der zur Reinigung des Partikelfilters von den darin abgelagerten Partikeln führt. Durch Schließen eines weiteren Ventils nach dem Abscheider wird der Reinigungseffekt des Partikelfilters zusätzlich unterstützt.By the arrangement of a valve in the exhaust pipe after the branch the exhaust gas recirculation line becomes the recirculated exhaust gas amount adjustable. Furthermore can by controlling the valve in the particle filter a pressure surge through the exhaust gases are generated, which is used to clean the particulate filter from the particles deposited therein. By closing a Another valve after the separator is the cleaning effect of Particulate filter in addition supported.
Der Vorteil der erfindungsgemäßen Lösung besteht darin, dass bei einem reduzierten Schadstoffanteil in den Abgasen der Verbrennungskraftmaschine ein nahezu reines Abgas der Brennkraftmaschine zugeführt wird. Dadurch werden Ablagerungen an dem Verdichter des Abgasturboladers weitestgehend vermieden. Eine bessere Steuerung des Brennablaufs in der Brennkraftmaschine ist somit auch bei unterschiedlichen Lastfällen möglich. Insgesamt wird dadurch der Wirkungsgrad der Brennkraftmaschine weiter verbessert.Of the Advantage of the solution according to the invention exists in that at a reduced pollutant content in the exhaust gases the internal combustion engine, a nearly pure exhaust gas of the internal combustion engine is supplied. As a result, deposits on the compressor of the exhaust gas turbocharger largely avoided. Better control of the combustion process in the internal combustion engine is thus possible even with different load cases. All in all As a result, the efficiency of the internal combustion engine is further improved.
Ein weiterer Vorteil der erfindungsgemäßen Losung besteht in der steuerbaren Reinigung des Partikelfilters durch Erzeugung eines Druckstoßes durch die Anordnung des regelbaren Ventils in der Abgasleitung nach dem Partikelfilter.One Another advantage of the invention consists in the controllable solution Cleaning the particle filter by generating a pressure surge through the arrangement of the controllable valve in the exhaust pipe after the Particulate filter.
