Abstract
Description
Die Erfindung betrifft eine Vorrichtung zur Heißgaserzeugung im Abgasstrang eines Verbrennungsmotors, mit einer Primärbrennkammer, in die eine Drallluft-Zerstäuberdüse mündet, und einer Sekundärbrennkammer, die mit einer Abgasleitung des Motors verbunden ist. Insbesondere betrifft die Erfindung eine Heißgaserzeugung für eine Rußfiltervorrichtung, speziell in Dieselmotoren.The The invention relates to a device for hot gas production in the exhaust system an internal combustion engine, with a primary combustion chamber into which a swirl air atomizer nozzle opens, and a secondary combustion chamber, which is connected to an exhaust pipe of the engine. Especially The invention relates to a hot gas production for one Soot filter device especially in diesel engines.
In
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zur Heißgaserzeugung im Abgasstrang eines Verbrennungsmotors anzugeben, die einen verringerten Druckbedarf und einen großen Regelbereich hat.Of the Invention is based on the object, a device for hot gas production indicate in the exhaust system of an internal combustion engine, which reduced a Printing needs and a big one Control range has.
Die Vorrichtung nach der vorliegenden Erfindung ist durch den Patentanspruch 1 definiert. Sie zeichnet sich dadurch aus, dass in den Abgasstrom des Motors ein Brennstoffeinlass mündet und dass in der Sekundärbrennkammer eine Verbrennung des zugeführten Brennstoffs mit dem in den Motorabgasen enthaltenden Sauerstoff erfolgt.The Device according to the present invention is defined by the claim 1 defined. It is characterized by the fact that in the exhaust stream of Engine opens a fuel inlet and that in the secondary combustion chamber a combustion of the supplied Fuel with the oxygen contained in the engine exhaust he follows.
Die
Erfindung sieht eine zweistufige Verbrennung mit aktiven Brennstoffstufen
vor. Das Prinzip der Primärstufe
entspricht im wesentlichen demjenigen von
Die Sekundärbrennkammer ist in der Abgasleitung angeordnet, wobei ihre Abgase einer Mischkammer zugeführt werden. In die Mischkammer werden auch die aus der Primärbrennkammer ausströmenden Verbrennungsgase des Primärbrenners eingeleitet.The secondary combustion chamber is arranged in the exhaust pipe, with its exhaust gases of a mixing chamber supplied become. In the mixing chamber are also from the primary combustion chamber outflowing Combustion gases of the primary burner initiated.
Es besteht die Möglichkeit, die Sekundärbrennkammer hinter dem Auslass anzuordnen, durch den die Verbrennungsgase der Primärbrennkammer aus dieser austreten. In diesem Fall geht die Sekundärbrennkammer in die Mischkammer über.It it is possible, the secondary combustion chamber behind the outlet, through which the combustion gases of the Primary combustion chamber off this leak. In this case, the secondary combustion chamber passes into the mixing chamber.
Gemäß einer bevorzugten Ausgestaltung der Erfindung ist ein Mischer im Gasstrom hinter der Sekundärbrennkammer angeordnet. Dieser Mischer dient dazu, die Verbrennungsgase des Primärbrenners mit denjenigen des Sekundärbrenners zu vermischen und einem nachgeschalteten Rußfilter ein weitgehend homogenes Gasgemisch zuzuführen.According to one preferred embodiment of the invention is a mixer in the gas stream behind the secondary combustion chamber arranged. This mixer serves to burn the combustion gases of the primary burner with those of the secondary burner to mix and a downstream soot a largely homogeneous Feed gas mixture.
Die Primärbrennkammer kann seitliche Ausströmöffnungen aufweisen oder eine zu der Achse des Primärbrenners ausgerichtete Ausströmöffnung. Im Falle einer axial ausgerichteten Ausströmöffnung, kann im Strömungsweg der Verbrennungsgase hinter der Ausströmöffnung der Sekundärbrenner angeordnet sein, wobei dieser dem Strömungsweg der Verbrennungsgase der Primärbrennkammer entgegengerichtet ist. Dabei ist vorzugsweise der Sekundärbrenner mit einer Verdampferschale versehen, die den von den Verbrennungsgasen mitgeführten Rest-Brennstoff auffängt und verdampft. Die Verdampferschale bildet zugleich eine Umlenkvorrichtung zum Umlenken der Verbrennungsgase des Sekundärbrenners.The primary combustion chamber can have lateral outflow openings or an outflow opening aligned with the axis of the primary burner. in the Trap of an axially aligned outflow, can in the flow path the combustion gases behind the discharge port of the secondary burner be arranged, this the flow path of the combustion gases the primary combustion chamber is opposite. In this case, preferably, the secondary burner provided with an evaporator shell, that of the combustion gases entrained residual fuel fields and evaporates. The evaporator shell also forms a deflection device for redirecting the combustion gases of the secondary burner.
Gemäß einer bevorzugten Ausgestaltung der Erfindung ist die Sekundärbrennkammer durch eine Ringwand begrenzt, die einen zu dem Rußfilter führenden Durchlass aufweist.According to one preferred embodiment of the invention is the secondary combustion chamber bounded by an annular wall leading to the soot filter Passage has.
Die Brennstoffleitung des Sekundärbrenners ist gemäß einer bevorzugten Ausgestaltung der Erfindung von der Ringwand, die die Sekundärbrennkammer begrenzt, getragen. Vorzugsweise ist die Brennstoffleitung in der Ringwand angeordnet, so dass sie gegen hohe Temperaturen geschützt ist.The Fuel line of the secondary burner is according to a preferred embodiment of the invention of the annular wall, the secondary combustion chamber limited, worn. Preferably, the fuel line is in the Ring wall arranged so that it is protected against high temperatures.
Im Folgenden werden unter Bezugnahme auf die Zeichnungen Ausführungsbeispiele der Erfindung näher erläutert.in the Embodiments will be described below with reference to the drawings closer to the invention explained.
Es zeigen:It demonstrate:
Die dargestellte Vorrichtung zur Heißgaserzeugung im Abgasstrang eines Verbrennungsmotors ist hier speziell in Verbindung mit der Rußfiltervorrichtung eines Dieselmotors dargestellt. In diesem Fall besteht der Verbrennungsmotor aus dem Dieselmotor, dessen Abgase durch die Rußfiltervorrichtung gereinigt werden. Von Zeit zu Zeit ist eine Reinigung der Rußfiltervorrichtung durch Heißgase erforderlich, die den angesammelten Ruß verbrennen. Zur Erzeugung dieser Heißgase dient die nachstehend beschriebene Vorrichtung.The illustrated device for hot gas production in the exhaust system an internal combustion engine is here specifically in conjunction with the soot filter device a diesel engine shown. In this case, there is the internal combustion engine from the diesel engine, whose exhaust gases are cleaned by the soot filter device become. From time to time, a cleaning of the soot filter device by hot gases required, which burn the accumulated soot. To produce these hot gases serves the device described below.
