Description
Die Erfindung betrifft einen Abgasturbolader für eine Brennkraftmaschine und ein Verfahren zum Betrieb eines Abgasturboladers nach dem Oberbegriff des Anspruchs 1 bzw. des Anspruchs 6.The The invention relates to an exhaust gas turbocharger for an internal combustion engine and a method for operating an exhaust gas turbocharger according to the preamble of claim 1 or claim 6.
Abgasturbolader werden sowohl bei fremdgezündeten als auch bei selbstzündenden Brennkraftmaschinen zur Erhöhung der Zylinderladung eingesetzt. Die Erhöhung der Zylinderladung führt neben einer Leistungssteigerung zu einer Steigerung des Verbrennungsluftverhältnisses und damit bei selbstzündenden Brennkraftmaschinen zu einer Reduzierung der Russbildung im unteren und mittleren Last- und Drehzahlbereich und kann, je nach Verbrennungstemperatur, eine Reduzierung der Stickoxidemission zur Folge haben.turbocharger are both foreign-charged as well as self-igniting Internal combustion engines to increase used the cylinder charge. The increase of the cylinder charge leads next an increase in output to an increase in the combustion air ratio and with self-igniting Internal combustion engines to reduce soot formation in the lower and medium load and speed range and, depending on the combustion temperature, result in a reduction of the nitrogen oxide emission.
Abgasturbolader bestehen in der Regel aus zwei über eine feste Welle gekoppelten Strömungsmaschinen, einer Turbine, die über den expandierenden Abgasmassenstrom der Brennkraftmaschine beaufschlagt wird und einem Verdichter, der über eine drehbar gelagerte Welle von der Turbine angetrieben wird und angesaugte Luft komprimiert. Da Strömungsmaschinen ein anderes Betriebverhalten als Brennkraftmaschinen aufweisen, gilt es den Abgasturbolader und/oder seine Peripherie so zu gestalten, dass sowohl im niedrigen als auch im oberen Last- und Drehzahlbereich für das gewünschte Betriebsverhalten der Brennkraftmaschine vom Abgasturbolader ausreichend Luft zur Verfügung gestellt wird.turbocharger usually consist of two over a fixed shaft coupled turbomachinery, a turbine over acted upon by the expanding exhaust gas mass flow of the internal combustion engine and a compressor that is over a rotatably mounted shaft is driven by the turbine and sucked in compressed air. As turbomachines another Operating behavior as internal combustion engines, it applies the Turbocharger and / or its periphery to be designed so that both in the low and in the upper load and speed range for the desired Operating behavior of the internal combustion engine from the exhaust gas turbocharger sufficient Air available is provided.
Der Abgasturbolader reagiert aufgrund seines Massenträgheitsmomentes bei plötzlicher Steigerung der Last und/oder Drehzahl der Brennkraftmaschine verzögert. Dieses verzögerte Ansprechverhalten ist unter dem geläufigen Namen „Turboloch" bekannt und zeichnet sich dadurch aus, dass der Abgasturbolader der Brennkraftmaschine für den entsprechenden Betriebspunkt zu wenig Luft zur Verfügung stellt. Das schlechte Ansprechverhalten bewirkt im Instationärbetrieb der Brennkraftmaschine neben einer ungenügenden Beschleunigung einen hohen Kraftstoffverbrauch, der mit der Beseitigung des schlechten Ansprechverhaltens reduziert werden kann.Of the Exhaust gas turbocharger reacts due to its mass moment of inertia at sudden Increasing the load and / or speed of the internal combustion engine is delayed. This delayed Responsiveness is known under the common name "turbo lag" and draws characterized by the fact that the exhaust gas turbocharger of the internal combustion engine for the corresponding Operating point provides too little air. The bad Responsiveness causes in unsteady operation of the internal combustion engine in addition an insufficient one Acceleration high fuel consumption, with the elimination of poor response can be reduced.
Wird der Abgasturbolader für den Nennleistungspunkt der Brennkraftmaschine ausgelegt, so ist er in der Regel für ein schnelles Ansprechen im unteren und mittleren Last- und Drehzahlbereich zu groß ausgelegt und liefert aufgrund seines Massenträgheitsmomentes unbefriedigende Ergebnisse des Betriebsverhaltens der Brennkraftmaschine hinsichtlich Motor-Drehmoment, Agilität und Verbrauch. Unterschiedliche Ansätze versuchen das Ansprechverhalten des Abgasturboladers im genannten Bereich zu verbessern.Becomes the turbocharger for designed the rated power point of the internal combustion engine, it is usually for a fast response in the lower and middle load and speed range designed too big and provides unsatisfactory due to its moment of inertia Results of the operating behavior of the internal combustion engine with regard to engine torque, agility and consumption. Different approaches try the response of the exhaust gas turbocharger in said Improve area.
Einer der Ansätze ist dabei die Kopplung des Abgasturboladers mit einer elektrischen Maschine. Die elektrische Maschine ist starr mit dem Abgasturbolader verbunden und beschleunigt diesen bei Bedarf. Die erforderlichen Leistungen liegen für beispielsweise einen Vierzylindermotor bei etwa 1-2 kW. Aktuelle Kraftfahrzeug-Bordnetze stoßen dabei an ihre Leistungsgrenze. Ein großer Teil der eingespeisten Energie dient der Eigenbeschleunigung der elektrischen Maschine. Der mit dem Abgasturbolader verbundene Rotor der elektrischen Maschine reduziert aufgrund seines Trägheitsmomentes die Dynamik des Abgasturboladers im nichtunterstützten Betriebsbereich.one the approaches is the coupling of the exhaust gas turbocharger with an electric Machine. The electric machine is rigid with the turbocharger connected and accelerates this if necessary. The necessary Services are for For example, a four-cylinder engine at about 1-2 kW. current Automotive vehicle electrical systems encounter thereby at their performance limit. A large part of the fed Energy is used for the self-acceleration of the electric machine. The rotor of the electric machine connected to the exhaust gas turbocharger reduced due to its moment of inertia the dynamics of the turbocharger in the non-assisted operating range.
