Abstract
Description
Es ist bekannt, das ein Verbrennungsmotor (
Ein Verbrennungsmotor erzeugt aus einem Energieträger durch einen Verbrennungsprozess, meist mit Diesel oder Benzinkraftstoff der entsprechenden Normung betrieben, mechanische Energie in Form einer Drehbewegung der Kurbelwelle (
Die vom Verbrennungsmotor erzeugte Kraft muss nun an die Antriebsräder (
Auf dem Weg der Kraftweiterleitung von Verbrennungsmotor zu den Rädern, und dabei zählen auch die Kurbelwelle und alle mechanischen Kraftüberträger wie Zahnräder, Steuerkette, Steuerriemen, sonstige Wellen des Verbrennungsmotors mit, befindet sich ein oder mehrere elektrische Motoren (
Ein elektrischer Motor/Generator, der mit dem Kurbelwellenflansch (
Ein elektrischer Motor/Generator, der zwischen Kraftübertragungs-Einheiten verbaut ist kann den Verbrennungsmotor starten und/oder als Generator zur Stromerzeugung arbeiten und/oder Bremsenergie des Fahrzeugs in elektrischen Strom wandeln bzw. elektrischen Strom in Beschleunigungsenergie sowie den Verbrennungsmotor in Bewegung halten ohne das dieser Kraftstoff verbraucht und dennoch alle Nebenaggregate betriebsbereit sind. Weiterhin sind sonstige Betriebszustände denkbar. Diese elektrischen Motoren erhalten elektrische Energie von einem Generator oder einem elektrischen Motor der als Generator wirkt oder aus einem Stromspeicher um die Energie in Antriebsenergie umzuwandeln.An electric motor / generator installed between power transmission units may start the engine and / or operate as a generator to generate power and / or convert braking energy of the vehicle into electrical power, or keep electrical power in acceleration energy and the engine in motion without it Fuel consumed and yet all ancillaries are ready for use. Furthermore, other operating conditions are conceivable. These electric motors receive electrical energy from a generator or electric motor acting as a generator or from a power storage to convert the energy into drive energy.
Die Abwärme des Verbrennungsmotors wird durch das Kühlwassersystem (
Die Expansionsmaschine des ORC Kreislaufes wandelt die thermische Energie des gasförmigen Wärmeträgermediums in eine andere Energieform. Diese kann mechanisch, in Form einer drehenden Welle aus der Expansionsmaschine ausgegeben werden, welche als Kraftabgabewelle der Expansionsmaschine bezeichnet wird oder in elektrischer Form ausgegeben werden. Bei einer elektrischen Energieausgabe, wird die Wärmeenergie des gasförmigen Arbeitsmittels noch in der Expansionsmaschine durch einen Generator in elektrische Energie gewandelt und durch einen elektrischen Stromanschluss ausgegeben. Dieser Strom kann nun in einem Stromspeicher gespeichert werden oder steht als Antriebsenergie für die Elektromotoren zur Verfügung.The expansion machine of the ORC cycle converts the thermal energy of the gaseous heat transfer medium into another form of energy. This can be output mechanically, in the form of a rotating shaft from the expansion machine, which is referred to as a power output shaft of the expansion machine or output in electrical form. In an electrical energy output, the heat energy of the gaseous working fluid is still converted in the expansion machine by a generator into electrical energy and output by an electrical power connection. This current can now be stored in a power storage or is available as drive energy for the electric motors.
Weiterhin besteht dieses Antriebskonzept aus einen Stromspeicher (
Um eine Steigerung der Energieeffizienz zu erhalten müssen die Bauteile in einer besonderen Art und Weise zusammenarbeiten, die in ihrer Grundfunktion gleich ist aber auf verschiedenen Wegen realisiert werden kann. Folgendermaßen funktioniert diese Zusammenarbeit der Komponenten.To obtain an increase in energy efficiency, the components must work together in a special way, which is the same in their basic function but can be realized in different ways. This cooperation of the components works as follows.
Während des Beschleunigungsvorgangs des Fahrzeuges erzeugt der Verbrennungsmotor aus chemischer Energie, durch Verbrennung des Kraftstoffes, eine mechanische Energie an der Kurbelwelle, also Antriebskraft. Weiterhin entsteht Wärme, die durch den Kühler und die Abgasanlage abgeführt wird. Die mechanische Energie der Kurbelwelle wird durch eine, wie bereits beschriebene, Kraftübertragungsart zu den Antriebsrädern geleitet.During the acceleration process of the vehicle, the internal combustion engine generates from chemical energy, by combustion of the fuel, a mechanical energy at the crankshaft, that is, driving force. Furthermore, heat is generated, which is dissipated by the radiator and the exhaust system. The mechanical energy of the crankshaft is conducted to the drive wheels by a mode of transmission as already described.
Die Wärmeüberträgermedien Kühlwasser und Abgas, durchlaufen nach ihrem Austritt aus dem Verbrennungsraum bzw. Kühlkanal, zum Teil oder vollmengig, einzeln oder getrennt voneinander oder nacheinander oder durch einen Hilfskreis, den Verdampferwärmetauscher einer ORC Anlage. Danach gelangen die Wärmeüberträgermedien zu ihrer Kühlstelle bzw. ins Freie.The heat transfer media cooling water and exhaust gas, after passing out of the combustion chamber or cooling channel, partially or fully, individually or separately from each other or successively or by an auxiliary circuit, the evaporator heat exchanger of an ORC system. Thereafter, the heat transfer media reach their cold spot or the outdoors.
Dieser Verdampferwärmetauscher verdampft ein Arbeitsmedium des geschlossenen ORC Kreislaufes und erhöht den Energiegehalt des Dampfes. Der Dampf durchströmt anschließend eine Expansionsmaschine, die den Dampf expandiert und zum Teil in nutzbare Energie umwandelt. Dabei kann die Energie mechanisch in Form einer Drehbewegung ausgegeben werden. Diese Rotationsenergie kann, durch entsprechende Anschlüsse, in die drehenden Teile des Verbrennungsmotors einleitet werden, in die drehenden Teile der/des Elektromotors einleitet werden, an einen Generator angeschlossen werden oder durch sonstige Anschlüsse des Antriebsstrangs eingeleitet werden. Eine andere Bauart der Expansionsmaschine wandelt den Energiegehalt des Dampfes ebenfalls in mechanische Energie aber anders als bereits beschrieben, wird die mechanische Energie noch im Bauteil „Expansionsmaschine” in elektrische Energie gewandelt. Ausgegeben wird elektrischer Strom mit entsprechender Leistung. Diese elektrische Leistung wird nun durch eine Steuerungsstrecke entweder zum Stromspeicher geleitet um die Leistung zu speichern oder sie wird durch einen Elektromotor in den Antriebsstrang eingeleitet um als Antriebsenergie zu wirken oder es werden beide Wege bedient. Der gleiche Weg wird beim Anschluss eines Generators an eine mechanisch ausgebende Expansionsmaschine beschritten.This evaporator heat exchanger vaporizes a working medium of the closed ORC cycle and increases the energy content of the steam. The steam then flows through an expansion machine, which expands the steam and partly converts it into usable energy. The energy can be output mechanically in the form of a rotary movement. This rotational energy can, by appropriate connections, be introduced into the rotating parts of the internal combustion engine, be introduced into the rotating parts of the / of the electric motor, be connected to a generator or be initiated by other connections of the drive train. Another type of expansion machine also converts the energy content of the steam into mechanical energy, but unlike what has already been described, the mechanical energy is still converted into electrical energy in the "expansion machine" component. Electric power with corresponding power is output. This electrical power is now passed through a control path either to the power storage to store the power or it is introduced by an electric motor in the drive train to act as drive energy or both ways are served. The same way is followed when connecting a generator to a mechanically issuing expansion machine.
Nachdem der Dampf in der Expansionsmaschine gearbeitet hat durchströmt er den Regenerationswärmetauscher und anschließend den Kondensator, wo wieder flüssiges Arbeitsmittel entsteht. Eine Rückförderpumpe fördert das flüssige Arbeitsmittel durch den Regenerationswärmetauscher zurück zu den Verdamfungswärmetauscher/n. Der Regenerationswärmetauscher muss nicht zwingend verbaut sein.After the steam has worked in the expansion machine, it flows through the regeneration heat exchanger and then the condenser, where again liquid working fluid is produced. A recirculation pump conveys the liquid working fluid through the regeneration heat exchanger back to the Verdamfungswärmetauscher / n. The regeneration heat exchanger does not necessarily have to be installed.
Weiterhin kann währen des Beschleunigungsvorgang elektrische Energie aus dem Stromspeicher, durch einem oder mehrere Elektromotoren, die im Antriebsstrang verbaut sind, in Antriebsenergie gewandelt werden. Dabei hängt die Höhe der eingeleiteten Energie von der Leistung ab, die angefordert wird, von der momentan abgegebenen Leistung des ORC Prozesses, dem Ladezustand und der Leistung des Stromspeichers, von der Auslastung der Elektromotoren die von der ORC Anlage gespeist werden, vom Betriebszustand des Verbrennungsmotors und von zu erwarteten Betriebszuständen, die in der Systemsteuerung gespeichert sind.Furthermore, during the acceleration process, electrical energy can be converted into drive energy from the power storage device by one or more electric motors installed in the drive train. In this case, the amount of energy input depends on the power requested, the current output of the ORC process, the state of charge and the power of the current memory, the load of the electric motors powered by the ORC system, the operating condition of the internal combustion engine and expected operating states stored in the system controller.
Während des Teillastbetriebes oder bei geringer Kraftanforderung des Fahrzeugs kann der Verbrennungsmotor nun vom Antriebsstrang getrennt und ausgeschaltet werden. Die benötigte Antriebsenergie wird nun durch die ORC Anlage, die anfallende Rest-Wärme des Verbrennungsmotors nutzt um Energie zu erzeugen, die durch einen Elektromotor in den Antriebsstrang eingespeist wird und/oder durch den Energiespeicher zur Verfügung gestellt, der über einen Elektromotor Energie in den Antriebsstrang gibt. Nach erkalten des Verbrennungsmotors und nach entleeren des Stromspeichers wird der Verbrennungsmotor wieder gestartet. Unter Umständen kann es im Teillastbereich auch sinnvoll sein den Verbrennungsmotor weiter mitlaufen zu lassen und nur dessen Leistung zu drosseln.During part-load operation or when the vehicle requires little power, the internal combustion engine can now be disconnected from the drive train and switched off. The required drive energy is now through the ORC system that uses residual heat of the internal combustion engine to generate energy that is fed by an electric motor in the drive train and / or made available by the energy storage, the power via an electric motor in the drive train gives. After the internal combustion engine has cooled down and the power accumulator has been emptied, the internal combustion engine is restarted. Under certain circumstances, it may also be useful in the partial load range to continue to run the internal combustion engine and only to throttle its performance.
Während eines Bremsvorgangs des Fahrzeugs wird die anfallende Bremsenergie durch Generatoren im Antriebsstrang in elektrischen Strom umgewandelt, der im Stromspeicher gespeichert wird. Dabei sind die die Generatoren die selben Bauteile, die während einer Beschleunigung als Motor wirken. Weiterhin wird die Restwärme des Verbrennungsmotors durch die ORC Anlage in Strom verwandelt, der ebenfalls im Stromspeicher gespeichert wird. Der Verbrennungsmotor kann mm wieder vom Antriebsstrang getrennt und ausgeschaltet werden.During a braking process of the vehicle, the resulting braking energy is converted by generators in the drive train into electricity, which is stored in the power storage. The generators are the same components that act as a motor during acceleration. Furthermore, the residual heat of the internal combustion engine is converted by the ORC system into electricity, which is also stored in the electricity storage. The internal combustion engine can be disconnected from the drive train and switched off again.
Während Zeiten in denen keine Antriebsleistung benötigt wird, kann der Verbrennungsmotor ausgeschaltet werden und alle Verbraucher des Fahrzeuges erhalten ihre benötigte Energie durch den Stromspeicher.During times in which no drive power is needed, the engine can be turned off and all consumers of the vehicle get their required energy through the power storage.
Das Zusammenwirken der einzelnen Komponenten wird durch eine Systemsteuerung/elektrische Regeleinrichtung (

Die Erfindung stellt eine Möglichkeit dar, wie die thermische Verlustenergie eines Verbrennungsmotors in Kraftfahrzeugen in Antriebsenergie umgewandelt wird und wie diese in das Antriebskonzept eines Hybridfahrzeugs mit Verbrennungsmotor, mit teil oder voll-elektrischen Antriebsstrang und Stromspeicher integriert wird.The invention represents a possibility of how the thermal energy loss of an internal combustion engine in motor vehicles is converted into drive energy and how it is integrated into the drive concept of a hybrid vehicle with an internal combustion engine, with a partially or fully electric drive train and energy storage.
Stand der TechnikState of the art
Der Verbrennungsmotor eines Kraftfahrzeuges oder Fahrzeuges erzeugt auf Grund seiner Arbeitsweise eine hohe Menge an Wärme, die weder als Antriebsenergie noch in sonstiger Form zum Betrieb des Fahrzeugs beitragen kann. Somit kann der Energiegehalt des eingesetzten Kraftstoffes nicht in vollem Umfang genutzt werden und die Wärmeenergie wird als Verlustenergie an die Umwelt abgegeben. Aufgrund steigender Energiepreise wird es nötig die eingesetzte Energie besser auszunutzen und so entstanden Fahrzeuge mit sogenannten Hybridantrieb. Fahrzeuge mit Hybridantrieb wandeln unter anderem Bremsenergie in elektrischen Strom um, der in einem eigens dafür vorgesehenen Stromspeicher gespeichert wird. Bei erneuter Kraftanforderung wird diese gespeicherte elektrische Energie wieder in Antriebsenergie umgewandelt, was die Kraftstoffeffizienz steigert. Die getätigte Erfindung nutzt die Vorteile der technischen Voraussetzungen der Hybridantriebe um eine weitere Energiequelle in den Fahrzeugstrang zu integrieren und den Kraftstoffeinsatz zu senken.Due to its mode of operation, the internal combustion engine of a motor vehicle or vehicle generates a high amount of heat, which can contribute to the operation of the vehicle neither as drive energy nor in any other form. Thus, the energy content of the fuel used can not be fully utilized and the heat energy is released as energy loss to the environment. Due to increasing energy prices, it will be necessary to make better use of the energy used, and so vehicles with so-called hybrid drive were created. Among other things, vehicles with hybrid drive convert braking energy into electricity, which is stored in a specially designed power storage. Upon renewed force request, this stored electrical energy is converted back into drive energy, which increases the fuel efficiency. The achieved invention uses the advantages of the technical requirements of the hybrid drives to integrate a further source of energy in the vehicle train and to reduce fuel consumption.
