Aufgabe der Erfindung ist, eine gattungsgemäße Vorrichtung weiter zu entwickeln und deren Verwendbarkeit in einem Fahrzeug zu optimieren.task The invention is to further develop a generic device and to optimize their usability in a vehicle.
Die Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst.The The object is achieved by the Characteristics of claim 1 solved.
Gemäß der Erfindung ist ein Energiewandler vorgesehen, der bezogen auf eine Abgasströmung stromab eines Katalysators in einer Abgasleitung eines Antriebsaggregats angeordnet ist. Ein Vorteil ist, dass der Betrieb des Energiewandlers entkoppelt vom Betrieb des Katalysators erfolgt. Insbesondere das Einstellen einer notwendigen Betriebstemperatur des Katalysators und/oder gegebenenfalls eine Lambdaregelung einer bevorzugten Brennkraftmaschine als Antriebsaggregat wird vereinfacht. Der Betrieb wird insgesamt stabiler. Der Katalysatorbetrieb wird nicht beeinflusst.According to the invention an energy converter is provided which is downstream of an exhaust gas flow a catalyst in an exhaust pipe of a drive unit is arranged. An advantage is that the operation of the energy converter decoupled from the operation of the catalyst takes place. In particular, that Setting a necessary operating temperature of the catalyst and / or optionally a lambda control of a preferred internal combustion engine as a drive unit is simplified. The operation is total stable. Catalyst operation is not affected.
In einer bevorzugten Ausgestaltung bildet der Brenner mit dem Energiewandler bezogen auf eine Wärmeströmung und/oder die Abgasströmung eine Serienschaltung, wobei der Brenner stromauf des Energiewandlers angeordnet ist. Dadurch ist sichergestellt, dass der Energiewandler unabhängig vom Betrieb des Antriebsaggregats arbeiten kann.In In a preferred embodiment, the burner forms with the energy converter based on a heat flow and / or the exhaust flow one Series connection, the burner upstream of the energy converter is arranged. This ensures that the energy converter independent of Operation of the drive unit can work.
In einer günstigen Weiterbildung ist der Brenner in der Abgasleitung zwischen dem Katalysator und dem Energiewandler angeordnet. Dadurch kann der Energiewandler direkt mit Abgas des Brenners und des Antriebsaggregats beaufschlagt werden. Da die Betriebsbedingungen des Brenners nicht nach einer Lastanforderung des Antriebsaggregats gerichtet werden müs sen, kann der Brenner in einem günstigen Emissionsbereich eingestellt werden.In a cheap one Continuing education is the burner in the exhaust pipe between the catalyst and arranged the energy converter. This allows the energy converter directly be acted upon with exhaust gas of the burner and the drive unit. Because the operating conditions of the burner are not according to a load request The drive unit must be directed sen, the burner in a Great Emission range are set.
In einer alternativen Ausgestaltung ist der Brenner zur Beheizung des Energiewandlers über eine Wärmetauscherfläche mit dem Energiewandler gekoppelt, während das Abgas des Brenners in den Katalysator geleitet ist. Dadurch kann die katalytische Wirkung des Katalysators ausgenutzt werden, während gleichzeitig ein Wärmeübertrag vom Brenner auf den Energiewandler stattfinden kann.In an alternative embodiment of the burner for heating the Energy converter over one Heat exchanger surface with coupled to the energy converter while the exhaust gas of the burner is passed into the catalyst. Thereby the catalytic effect of the catalyst can be exploited while at the same time a heat transfer from the burner to the energy converter.
In einer günstigen Ausgestaltung ist stromab des Katalysators aufeinander folgend ein Brenner, ein Wärmetauscher und ein Energiewandler angeordnet. Der Wärmetauscher kann überschüssige Wärme an Verbraucher, insbesondere an eine Innenraumheizung des Fahrzeugs, abführen. Dies führt insgesamt zu einer Verbrauchsersparnis des Antriebsaggregats.In a cheap one Embodiment is downstream of the catalyst one after the other Burner, a heat exchanger and an energy converter arranged. The heat exchanger can transfer excess heat to consumers, in particular to an interior heating of the vehicle, dissipate. This leads overall to a fuel economy of the drive unit.
In einer weiteren günstigen Ausgestaltung ist je eine Serienschaltung aus Brenner und Energiewandler stromauf und stromab des Katalysators angeordnet.In another cheap Design is ever a series circuit of burner and energy converter arranged upstream and downstream of the catalyst.
In einer weiteren günstigen Ausgestaltung ist der Energiewandler zumindest einer aus der Gruppe thermoionischer Wandler, thermovoltaischer Wandler, Amtec-System oder thermoelektrischer Wandler, vorzugsweise ein thermoelektrischer Wandler. Dadurch kann mit günstigem Wirkungsgrad aus der Abwärme des Antriebsaggregats und/oder des Brenners elektrische Leistung gewonnen werden. Besonders bevorzugt ist ein thermovoltaischer Wandler in einem Auspufftopf angeordnet.In another cheap Embodiment is the energy converter at least one of the group thermoionic Converter, thermoelectric converter, Amtec system or thermoelectric Transducer, preferably a thermoelectric converter. This can with favorable Efficiency from the waste heat the power pack and / or the burner electrical power be won. Particularly preferred is a thermovoltaic converter arranged in a muffler.
In einer günstigen Ausgestaltung ist der Energiewandler eine Stirlingmaschine. Dies ermöglicht die Umsetzung von Abwärme in mechanische Energie. Bevorzugt ist die Stirlingmaschine mit einer Welle eines Motor-Generators gekoppelt.In a cheap one Design is the energy converter a Stirling engine. This allows the Implementation of waste heat in mechanical energy. Preferably, the Stirling engine is with a Coupled shaft of a motor-generator.
