Description
Technisches GebietTechnical area
Die Erfindung betrifft einen Verbrennungsmotor mit einem Turbolader der im Oberbegriff des Anspruchs 1 angegebenen Gattung.The The invention relates to an internal combustion engine with a turbocharger the type specified in the preamble of claim 1.
Stand der TechnikState of the art
In Abgasanlagen von Verbrennungsmotoren ist bei bestimmten Betriebszuständen eine höhere Abgastemperatur wünschenswert. Außerdem werden Bauteile der Abgasanlage durch die im Abgas mitgeführten Partikel belastet.In Exhaust systems of internal combustion engines is a certain operating conditions higher exhaust gas temperature desirable. Furthermore become components of the exhaust system by the entrained in the exhaust particles loaded.
Der vorliegenden Erfindung liegt die Aufgabe zu Grunde, einen Verbrennungsmotor mit einem Turbolader der eingangs genannten Gattung zu schaffen, bei dem mit einfachen Mitteln eine Anhebung der Abgastemperatur und eine Abscheidung von Partikeln im Abgasstrom möglich ist.Of the The present invention is based on the object of an internal combustion engine to provide with a turbocharger of the type mentioned, in which by simple means an increase in the exhaust gas temperature and a separation of particles in the exhaust stream is possible.
Diese Aufgabe wird durch einen Verbrennungsmotor mit den Merkmalen des Anspruchs 1 gelöst.These Task is by an internal combustion engine with the characteristics of Claim 1 solved.
Offenbarung der ErfindungDisclosure of the invention
Besonders zweckmäßig ist die Anhebung der Eintrittstemperatur vor der Turbine des Abgasturboladers sowie die Abscheidung von Partikeln vor der Turbine. Zu diesem Zweck wird vorgeschlagen, dass der Heißgasaustritt des Wirbelrohres mit der Turbine verbunden ist. Besonders bei geringen Abgasmassenströmen wirkt sich eine höhere Eintrittstemperatur der Turbine günstig auf den Wirkungsgrad aus. Es ist jedoch auch möglich, dass der Heißgasaustritt mit einer nachgeschalteten Reinigungsstufe einer Abgasanlage verbunden ist. Dabei kann es sich um einen Katalysator handeln, der zur Reinigung eine bestimmte Temperatur des Abgases benötigt. Die Reinigungsstufe kann auch ein Partikelfilter sein, der in bestimmten Abständen oder je nach Belastung freigebrannt werden muss. Durch die Vorabscheidung von Partikeln im Wirbelrohr wird die Belastung des Partikelfilters reduziert.Especially is appropriate the increase of the inlet temperature in front of the turbine of the exhaust gas turbocharger and the separation of particles in front of the turbine. To this end It is suggested that the hot gas outlet of the vortex tube connected to the turbine. Especially at low exhaust gas mass flows a higher one Inlet temperature of the turbine low on the efficiency out. However, it is also possible that the hot gas outlet connected to a downstream purification stage of an exhaust system is. It may be a catalyst for cleaning a certain temperature of the exhaust gas needed. The cleaning stage can Also, be a particulate filter at specific intervals or must be burned depending on the load. By the pre-separation of particles in the vortex tube becomes the load of the particulate filter reduced.
Gemäß einer weiteren Ausgestaltung ist vor dem Eingang des Wirbelrohres eine Bypassleitung angeschlossen, die stromab des Heißgasaustritts in die Abgasleitung mündet. Dies hat den Vorteil, dass im Volllastfall das Wirbelrohr durch den Bypass überbrückt wird, da es sonst zu Drosselverlusten vor der Turbine des Abgasturboladers kommt bzw. eine Erhöhung der Ausschiebearbeit des Kolbens die Folge ist. Um eine Rückströmung in Richtung auf den Verbrennungsmotor zu vermeiden, ist in der Bypassleitung ein Schaltventil oder unter Umständen auch ein Rückschlagventil zweckmäßig.According to one Another embodiment is in front of the entrance of the vortex tube Bypass line connected downstream of the hot gas outlet in the exhaust pipe empties. This has the advantage that in full load case, the vortex tube the bypass is bypassed, otherwise there will be throttling losses in front of the turbocharger turbine comes or an increase the Ausschiebearbeit the piston is the result. To get a backflow in Direction to avoid the internal combustion engine is in the bypass line a switching valve or possibly also a check valve appropriate.
Vorzugsweise ist in der Druckleitung stromab des Verdichters ein Ladeluftkühler angeordnet und die Abgasrückführleitung mündet stromab des Ladeluftkühlers in die Druckleitung. Damit wird der Druckluft ein Abgasanteil mit reduzierter Temperatur zugeführt. Zur weiteren Absenkung der Temperatur des zugeführten Abgases kann ein Wärmetauscher in der Abgasrückführleitung vorgesehen sein. Um eine Rückströmung in Richtung auf den Abgasauslass des Verbrennungsmotors zu vermeiden, wird in der Abgasrückführleitung ein Rückschlagventil angeordnet.Preferably is arranged in the pressure line downstream of the compressor, a charge air cooler and the exhaust gas recirculation line ends downstream of the intercooler in the pressure line. Thus, the compressed air is an exhaust gas part with supplied reduced temperature. To further reduce the temperature of the supplied exhaust gas, a heat exchanger in the exhaust gas recirculation line be provided. To get a backflow in To avoid direction to the exhaust outlet of the internal combustion engine is in the exhaust gas recirculation line a check valve arranged.

Gemäß einer Ausführungsvariante kann der Abgasstrom so aufgeteilt werden, dass bereits vor dem Wirbelrohr eine Abgasleitung zu der Turbine abzweigt und an den Heißgasaustritt eine weitere Abgasleitung angeschlossen ist, die zu einer Reinigungsstufe einer Abgasanlage, beispielsweise einem Partikelfilter oder Katalysator führt.According to one variant the exhaust gas flow can be divided so that even before the vortex tube an exhaust pipe branches off to the turbine and to the hot gas outlet another exhaust pipe is connected, leading to a purification stage an exhaust system, such as a particulate filter or catalyst leads.
