Description
Die vorliegende Erfindung betrifft ein Verfahren und eine Vorrichtung zur Abgasnachbehandlung bei einer Brennkraftmaschine gemäß den Patentansprüchen. The present invention relates to a method and a device for exhaust aftertreatment in an internal combustion engine according to the claims.
Für einen wirksamen Betrieb der Abgasnachbehandlung einer Brennkraftmaschine ist es bekannt, in der Abgasanlage angeordneten Bauteilen Wärme zuzuführen. In der Abgasanlage angeordnete Bauteile sind insbesondere Filter oder Katalysatoren. Eine Wärmezufuhr zu einem solchen Bauteil erfolgt vor allem dann, wenn die Brennkraftmaschine noch nicht gestartet ist oder nur mit geringer Belastung und somit niedriger Abgastemperatur betrieben wird. Durch eine solche Wärmezufuhr wird die Abgasnachbehandlung günstig beeinflusst, da beispielsweise ein in der Abgasanlage angeordneter Katalysator auf diese Weise auch dann betriebsfähig ist, wenn dem Katalysator nicht ausreichend Wärme durch das Abgas zugeführt wird. Für eine solche Wärmezufuhr sind verschiedene Ansätze zur Abgasnachbehandlung einer Brennkraftmaschine bekannt, wobei beispielsweise ein Katalysator elektrisch beheizt wird. Beispielsweise gemäß der
Es ist Aufgabe der vorliegenden Erfindung, die bekannten Ansätze gemäß dem Stand der Technik weiter zu verbessern. It is an object of the present invention to further improve the known approaches according to the prior art.
Diese Aufgabe wird erfindungsgemäß mittels eines Verfahrens und einer Vorrichtung gemäß den Patentansprüchen gelöst. This object is achieved by means of a method and a device according to the claims.
Das erfindungsgemäße Verfahren ist dadurch gekennzeichnet, dass zur Zufuhr von Wärme zu abgasrelevanten Bauteilen bzw. Abgasnachbehandlungskomponenten ein Kreisprozess durchgeführt wird. Dabei wird einem Arbeitsmedium Wärme zugeführt. Das erwärmte Arbeitsmedium wird dann mittels eines Verdichters komprimiert, wobei Arbeit aufgewendet wird. Dem erwärmten und komprimierten Arbeitsmedium wird wiederum dadurch Wärme entzogen, dass das stromauf einer Turbine angeordnete abgasrelevante Bauteil bzw. die betreffende Abgasnachbehandlungskomponente erwärmt wird. Das abgekühlte Arbeitsmedium wird im weiteren Verlauf dann über der Turbine entspannt, so dass ein Teil der zur Kompression des erwärmten Arbeitsmediums aufgewendeten Arbeit zurückgewonnen wird. Dem durch die Entspannung noch weiter abgekühlten Arbeitsmedium stromab der Turbine wird erneut Wärme zugeführt und der zuvor beschriebene Kreislauf beginnt erneut. The method according to the invention is characterized in that a cyclic process is carried out for the supply of heat to exhaust-relevant components or exhaust aftertreatment components. In this case, heat is supplied to a working medium. The heated working medium is then compressed by means of a compressor, whereby work is spent. Heat is withdrawn from the heated and compressed working medium in turn by heating the exhaust gas-relevant component arranged upstream of a turbine or the exhaust gas aftertreatment component in question. The cooled working medium is then expanded over the turbine in the further course, so that part of the work expended for compression of the heated working medium is recovered. The still further cooled by the relaxation of the working fluid downstream of the turbine heat is supplied again and the cycle described above begins again.
Insbesondere erfolgt das erfindungsgemäße Verfahren in Verbindung mit einer Brennkraftmaschine, welche zunächst ein abgasrelevantes Bauteil aufweist, das in einer Abgasablage der Brennkraftmaschine angeordnet ist. Insbesondere handelt es sich bei diesem Bauteil um zumindest einen Katalysator. Es kommen natürlich auch andere für eine Abgasnachbehandlung relevante Bauteile in Betracht. Weiterhin ist in der Abgasanlage stromab des Bauteils eine Turbine angeordnet. Darüber hinaus verbindet eine erste Kurzschlussleitung die Abgasanlage stromab der Turbine mit einer Ansauganlage. Außerdem ist in der Ansauganlage stromab der Einmündung der ersten Kurzschlussleitung in die Ansauganlage ein Verdichter angeordnet. Ferner verbindet eine zweite Kurzschlussleitung die Ansauganlage stromab des Verdichters mit der Abgasanlage stromauf des Bauteils. In particular, the method according to the invention is carried out in conjunction with an internal combustion engine, which initially has an exhaust gas-relevant component which is arranged in an exhaust gas deposit of the internal combustion engine. In particular, this component is at least one catalyst. Of course, other components that are relevant for exhaust aftertreatment also come into consideration. Furthermore, a turbine is arranged downstream of the component in the exhaust system. In addition, a first short circuit line connects the exhaust system downstream of the turbine with an intake system. In addition, a compressor is arranged in the intake downstream of the junction of the first short-circuit line in the intake. Furthermore, a second short circuit line connects the intake downstream of the compressor with the exhaust system upstream of the component.
Erfindungsgemäß wird der Verdichter mittels einer elektrischen Maschine angetrieben und zwar dann, wenn eine Zufuhr von Wärme zu dem Bauteil erfolgen soll, so dass ein Arbeitsmedium von der Abgasanlage durch die erste Kurzschlussleitung in die Ansauganlage gefördert wird. Dem Arbeitsmedium wird stromauf des Verdichters Wärme zugeführt und im weiteren Verlauf wird das Arbeitsmedium mittels des Verdichters komprimiert. Im noch weiteren Verlauf wird das Arbeitsmedium mittels der zweiten Kurzschlussleitung von der Ansauganlage in die Abgasanlage und somit zu dem Bauteil geleitet. Auf diese Weise wird die Wärme, welche dem Arbeitsmedium vor der Kompression zugeführt wurde und dem Arbeitsmedium durch die Kompression zugeführt wurde, zu dem Bauteil geleitet und an das Bauteil abgegeben. According to the invention, the compressor is driven by means of an electric machine, specifically when a supply of heat to the component is to take place, so that a working medium is conveyed from the exhaust system through the first short-circuit line into the intake system. The working fluid is supplied upstream of the compressor heat and in the course of the working fluid is compressed by means of the compressor. In still further course, the working medium is conducted by means of the second short-circuit line from the intake system into the exhaust system and thus to the component. In this way, the heat which has been supplied to the working medium prior to compression and supplied to the working medium by the compression is conducted to the component and delivered to the component.
Nachdem das Arbeitsmedium das Bauteil passiert hat, wird das Arbeitsmedium erfindungsgemäß in der Turbine entspannt. Dabei wird ein Teil der Arbeit durch einen Antrieb des Verdichters wieder zurückgewonnen, welche bei der Kompression des Arbeitsmediums mittels des Verdichters aufgewendet wurde. Stromab der Turbine wird das entspannte Arbeitsmedium über die erste Kurzschlussleitung von der Abgasanlage wieder in die Ansauganlage geleitet und dem Arbeitsmedium stromauf des Verdichters wird erneut Wärme zugeführt. After the working medium has passed through the component, the working medium is expanded according to the invention in the turbine. In this case, a part of the work is recovered by a drive of the compressor, which was spent in the compression of the working medium by means of the compressor. Downstream of the turbine, the expanded working medium is conducted back into the intake system via the first short-circuit line from the exhaust system, and heat is again supplied to the working medium upstream of the compressor.
Die erfindungsgemäße Energierückführung führt zu einer hohen Effizienz des Gesamtsystems, da die Wärmeenergie, welche nicht von dem zu erwärmenden Bauteil aufgenommen wurde, durch die Entspannung des Arbeitsmediums über der Turbine wieder in kinetische Energie umgewandelt wird, welche wiederum dem Antrieb des Verdichters dient. D. h. es wird die zum Antrieb des Verdichters mittels der elektrischen Maschine notwendige elektrische Energie reduziert. The energy return according to the invention leads to a high efficiency of the overall system, since the heat energy, which was not absorbed by the component to be heated, is converted back into kinetic energy by the relaxation of the working medium above the turbine, which in turn serves the drive of the compressor. Ie. it is the drive to the compressor by means of Electric machine reduces necessary electrical energy.
Weiterhin ist es von großem Vorteil, dass durch die Entspannung des Arbeitsmediums mittels der Turbine die Temperatur des Arbeitsmediums nach der Turbine reduziert wird, so dass eine große Temperaturdifferenz zwischen dem Arbeitsmedium und einer Wärmequelle zur Zufuhr von Wärme zu dem Arbeitsmedium zur Verfügung steht. D. h. infolge dieser großen Temperaturdifferenz, beispielsweise zwischen einem Speichermedium in einem Wärmespeicher und dem erfindungsgemäß zirkulierenden Arbeitsmedium ist ein großer Wärmestrom von dem Wärmespeicher in das Arbeitsmedium möglich. Der Vorteil des erfindungsgemäßen Konzepts gegenüber beispielsweise einem klassischen elektrischen Katalysator besteht darin, dass der COP deutlich größer ist als 1. Insbesondere werden schon vorhandene Komponenten einer Brennkraftmaschine für das erfindungsgemäße Verfahren verwendet. Insbesondere wird ein vorhandener AGR-Wärmetauscher für die Zufuhr von Wärme zu dem Arbeitsmedium verwendet. Dieser AGR-Wärmetauscher wird erfindungsgemäß vorteilhaft mit einem Wärmespeicher gekoppelt, so dass gespeicherte Wärme über einen elektrisch angetriebenen Verdichter bzw. einen E-ATL auf ein höheres Temperaturniveau gehoben wird. Der Arbeitsaufwand des Verdichters bleibt dabei erfindungsgemäß aufgrund der partiellen Rückgewinnung über die Turbine gering. Furthermore, it is of great advantage that the relaxation of the working medium by means of the turbine, the temperature of the working fluid is reduced to the turbine, so that a large temperature difference between the working fluid and a heat source for supplying heat to the working fluid is available. Ie. As a result of this large temperature difference, for example between a storage medium in a heat accumulator and the working medium circulating according to the invention, a large heat flow from the heat accumulator into the working medium is possible. The advantage of the inventive concept compared to, for example, a classic electric catalyst is that the COP is significantly greater than 1. In particular, already existing components of an internal combustion engine are used for the method according to the invention. In particular, an existing EGR heat exchanger is used for the supply of heat to the working medium. This EGR heat exchanger is advantageously coupled according to the invention with a heat accumulator, so that stored heat is raised to a higher temperature level via an electrically driven compressor or an E-ATL. The workload of the compressor remains according to the invention due to the partial recovery via the turbine low.
