Die erfindungsgemäße Brennkraftmaschine mit Abgasturbolader und Abgasrückführung mit den kennzeichnenden Merkmalen des Anspruchs 1 hat demgegenüber den Vorteil, dass eine einfache Anpassung des Turboladers an die verschiedenen Betriebszustände der Brennkraftmaschine, insbesondere im Abgasrückführungsbetrieb und im Motorbremsbetrieb, erfolgen kann, wobei auf den Einsatz von variablen oder starren Leitschaufeln vor der Turbine bzw. eines Schiebers im Turbinengehäuse verzichtet werden kann. Vorteilhafterweise ist dabei eine gute Regelung der Strömung auf die Turbine möglich, bei welcher das Aufstauverhalten an der Abgasturbine besser an den jeweiligen Betriebspunkt angepasst werden kann.The inventive internal combustion engine with Exhaust gas turbocharger and exhaust gas recirculation with the characterizing features of claim 1 has the other hand Advantage that a simple adaptation of the turbocharger to the various operating conditions the internal combustion engine, in particular in the exhaust gas recirculation mode and in engine braking operation, can be done, taking on the use of variable or rigid Guide vanes are dispensed with before the turbine or a slider in the turbine housing can. Advantageously, there is a good control of the flow the turbine possible, in which the Aufstauverhalten at the exhaust gas turbine better at the respective operating point can be adjusted.
Vorteilhafterweise ergibt sich durch den Entfall des Schiebers bzw. von zusätzlichen Leitschaufeln an der Turbine ein vereinfachter, kostengünstiger Aufbau des Abgasturboladers.advantageously, results from the elimination of the slider or additional Guide vanes on the turbine a simplified, cost-effective design the exhaust gas turbocharger.

Zur Verbesserung des Abgasverhaltens der Brennkraftmaschine, insbesondere zur NOx-Reduktion, ist die Abgasrückführung zur Rückführung von Abgas aus dem Abgasstrang in den Ansaugtrakt vorgesehen, bei der in Abhängigkeit von Zustandsgrößen und Betriebsparametern der Brennkraftmaschine sich in einfacher Art und Weise die Höhe des rückgeführten Abgasmassenstroms einstellen lässt. Vorteilhaft ist dabei, dass durch ein erstes Steuerelement und ein zweites Steuerelement sich sehr variabel eine Einstellung eines gewünschten Aufstaudrucks an der Turbine erzielen lässt, wodurch sich neben der Motorbremsleistung auch die Abgasrückführrate gut einstellen lässt.To improve the exhaust gas performance of the internal combustion engine, in particular for NO x reduction, the exhaust gas recirculation for the return of exhaust gas from the exhaust system is provided in the intake, in which depending on state variables and operating parameters of the internal combustion engine in a simple manner, the amount of recirculated exhaust gas mass flow can be set. It is advantageous that can be achieved by a first control and a second control very variable adjustment of a desired back pressure on the turbine, which can be well adjusted in addition to the engine braking power and the exhaust gas recirculation rate.
