Die vorliegende Erfindung beschäftigt sich mit dem Problem, für einen Verbrennungsmotor der gattungsgemäßen Art, eine verbesserte oder zumindest eine alternative Ausführungsform anzugeben, mittels welcher eine verbesserte Steuerung eines Clausius-Rankine-Prozesses ermöglicht wird. Die Erfindung beschäftigt sich außerdem mit dem Problem, ein Verfahren zu einer verbesserten Steuerung des Clausius-Rankine-Prozesses anzugeben.The present invention addresses the problem of providing, for an internal combustion engine of the generic type, an improved or at least one alternative embodiment by means of which improved control of a Rankine cycle process is made possible. The invention also addresses the problem of providing a method for improved control of the Rankine cycle.
Dieses Problem wird erfindungsgemäß durch die unabhängigen Ansprüche 1 und 3 gelöst. Vorteilhafte Ausführungsformen sind Gegenstand des abhängigen Anspruchs.This problem is solved according to the invention by the
Die Erfindung beruht auf dem allgemeinen Gedanken, bei einem Verbrennungsmotor mit einem Kühlkreis und einem Clausius-Rankine-Kreis zur Abwärmerückgewinnung im Clausius-Rankine-Kreis einen Ausgleichsbehälter zum Ausgleich von Volumen- und/oder Druckschwankungen eines innerhalb des Clausius-Rankine-Kreises zirkulierenden Arbeitsmediums vorzusehen, ebenso wie eine Druckregeleinrichtung, die den im Ausgleichsbehälter herrschenden Druck des Arbeitsmediums aktiv regelt bzw. steuert. Hierdurch ist es möglich, einen Kondensationsdruck und somit auch eine Kondensationstemperatur des im Clausius-Rankine-Kreis zirkulierenden Arbeitsmediums zu steuern bzw. zu regeln. Der Clausius-Rankine-Kreis ist dabei über eine Wärmetauschereinrichtung wärmeübertragend mit dem Kühlkreis verbunden, wobei in dem Clausius-Rankine-Kreis ein Kondensator, eine Pumpe und eine Expansionseinheit, beispielsweise eine Turbine, angeordnet sind. Durch den erfindungsgemäß vorgesehenen Ausgleichsbehälter und die ebenfalls erfindungsgemäß vorgesehene Druckregeleinrichtung ist es möglich, den Druck des Arbeitsmediums stromauf der Pumpe und stromab der Expansionseinheit zu beeinflussen und dadurch Einfluss auf einen Wirkungsgrad und Druckverhältnisse zu nehmen. Durch die aktive Steuerung bzw. Regelung des Drucks des Arbeitsmediums im Ausgleichsbehälter und damit im Clausius-Rankine-Kreis, ist es insbesondere möglich, eine erhöhte Flexibilität in der Prozesssteuerung/-regelung zu erreichen, wodurch insbesondere auch ein verbesserter Betrieb des Verbrennungsmotors möglich ist.The invention is based on the general idea, in an internal combustion engine with a cooling circuit and a Clausius-Rankine cycle for waste heat recovery in Clausius-Rankine cycle a surge tank to compensate for volume and / or pressure fluctuations of a circulating within the Clausius-Rankine cycle working medium to provide, as well as a pressure control device which actively controls or controls the pressure prevailing in the expansion tank of the working medium. This makes it possible to control or regulate a condensation pressure and thus also a condensation temperature of the working medium circulating in the Rankine cycle. The Clausius-Rankine cycle is heat transfer connected via a heat exchanger means with the cooling circuit, wherein in the Clausius-Rankine cycle, a capacitor, a pump and an expansion unit, such as a turbine, are arranged. By the inventively provided surge tank and also provided according to the invention pressure control device, it is possible to influence the pressure of the working fluid upstream of the pump and downstream of the expansion unit and thereby influence an efficiency and pressure conditions. The active control or regulation of the pressure of the working medium in the expansion tank and thus in the Rankine cycle, it is particularly possible to achieve increased flexibility in the process control / regulation, which in particular also an improved operation of the internal combustion engine is possible.
Bei einer vorteilhaften Weiterbildung der erfindungsgemäßen Lösung, weist der Ausgleichsbehälter einen Primärraum und einen Sekundärraum auf, die durch einen Membran geteilt sind, wobei der Primärraum kommunizierend mit dem Clausius-Rankine-Kreis und der Sekundärraum kommunizierend mit der Druckregeleinrichtung verbunden ist. Die Druckregeleinrichtung kann dabei in der Art eines steuerbaren bzw. regelbaren Ventils ausgebildet und mit einer Motorsteuerung verbunden sein. Ein zur Druckerhöhung des Arbeitsmediums im Primärraum erforderlicher erhöhter Druck im Sekundärraum kann beispielsweise aus einem Pressluftbehälter abgezweigt werden, wobei der Pressluftbehälter idealerweise durch eine Bremsrekuperation mit entsprechendem Druck gefüllt wird. Als Arbeitsmedium im Clausius-Rankine-Kreis ist vorzugsweise Wasser vorgesehen. Durch die gezielte Regelung des Drucks im Sekundärraum des Ausgleichsbehälters kann auf einfache aber dennoch effektive Weise der Druck im Primärraum des Ausgleichsbehälter und damit der Druck des Arbeitsmediums im Clausius-Rankine-Kreis eingestellt werden.In an advantageous development of the solution according to the invention, the expansion tank has a primary space and a secondary space, which are divided by a membrane, wherein the primary space is communicatively connected to the Rankine cycle and the secondary space communicating with the pressure control device. The pressure control device can be designed in the manner of a controllable or controllable valve and connected to a motor control. A required to increase the pressure of the working fluid in the primary chamber increased pressure in the secondary chamber can be diverted, for example, from a compressed air tank, the compressed air tank is ideally filled by a Bremsrekuperation with appropriate pressure. The working medium in the Rankine cycle is preferably water intended. The targeted control of the pressure in the secondary chamber of the expansion tank can be adjusted in a simple but effective manner, the pressure in the primary chamber of the expansion tank and thus the pressure of the working medium in the Rankine cycle.
