Abstract

The energy store uses a flywheel mass (5) which is rotated by the flow energy of the exhaust gases from an automobile combustion engine (1), for temporary energy storage by its rotation, the flywheel mass acting as the rotor of an electrical machine used as a generator for providing electrical energy fed to electrical loads (8,9) or an electrical energy store (12) via power electronic modules (7). The stored electrical energy can be fed back to the electrical machine for use as an electric drive motor.

Description

Verbrennungskraftmaschinen besitzen, bedingt durch ihre Wirkprinzipien, nur relativ geringe prozentuale Wirkungsgrade. Der Großteil der Energie, die durch den Verbrennungsprozeß freigesetzt wird, entweicht als Abwärme an die Atmosphäre. Im Zuge immer höherer Anforderungen an die Energie­ effizienz von Kraftfahrzeugen und den Umweltschutz wird die Aufmerksam­ keit zunehmend auf hybride Lösungen gelenkt. Von diesen verspricht man sich in naher Zukunft, neben weiteren alternativen Antriebskonzepten, einen hohen Anteil am Aufkommen produzierter Fahrzeuge und den Vorteil der teilweisen Übernahmefähigkeit bewährter und ausgereifter Motorentechnik. Hybridfahrzeuge besitzen getrennte Aggregate zur Bereitstellung von Energie (z. B. Verbrennungsmotor, Brennstoffzelle), zur Wandlung von Energieformen (z. B. Elektromotor) und zur Speicherung von Energie (Batterien, Superkon­ densatoren, Tanks für kompressible Medien oder Schwungmassenspeicher).Internal combustion engines have, due to their operating principles, only relatively low percentages of efficiency. Most of the energy which is released by the combustion process escapes as waste heat to the atmosphere. In the course of ever increasing demands on energy efficiency of motor vehicles and environmental protection is paying attention increasingly focused on hybrid solutions. One promises of these in the near future, in addition to other alternative drive concepts high proportion of the volume of vehicles produced and the advantage of Partial takeover capability of proven and mature engine technology. Hybrid vehicles have separate units to provide energy (e.g. internal combustion engine, fuel cell), for converting forms of energy (e.g. electric motor) and for storing energy (batteries, supercon capacitors, tanks for compressible media or flywheel mass storage).

Die Technik der Verbrennungsmotoren hat sich in den letzten Jahren dahin­ gehend weiterentwickelt, daß wieder häufiger mittels der Energie der Abgase aufgeladene Motoren zum Einsatz kommen. Dies hat zur Folge, daß gemäß
The technology of internal combustion engines has developed in recent years in such a way that engines which are charged with the energy of the exhaust gases are used more frequently. As a result, according to

Pe = i.n.we.Vh, (1)
P e = inw e .V h , (1)

dabei bedeuten:
i → Motorfaktor (4-Takt: i = 0, 5; 2-Takt: i = 1.0)
n → Drehzahl
Vh → Drehzahl
we → spezifische Arbeit
durch eine Steigerung der Dichte der Frischluft, die dem Motor zugeführt wird, die spezifische Arbeit im Motor erhöht werden kann.mean:
i → engine factor (4-stroke: i = 0, 5; 2-stroke: i = 1.0)
n → speed
V h → speed
w e → specific work
by increasing the density of the fresh air supplied to the engine, the specific work in the engine can be increased.

Das führt dazu, Motoren mit gleicher Leistung wie im unaufgeladenen Zu­ stand nun kleiner bauen zu können, was durch die geringeren zu beschleu­ nigenden und abzubremsenden Massen im Fahrbetrieb wiederum zu einer Kraftstoffeinsparung führt. Die Nutzung der im Abgas enthaltenen Energie kann jedoch durch solche Aggregate, meist Abgasturbolader, nicht vollständig erfolgen. Laut [1] reicht im üblichen Motorfahrzyklus bei sehr kleiner Teil­ last die im Abgasstrom enthaltene Energie oft nicht aus, die Motorfrischluft genügend zu verdichten. Andererseits steht bei Vollast so viel Energie zu Verfügung, daß diese nicht mehr sinnvoll weiterverwendet werden kann und meist über eine "Wastgate" genannte Einrichtung an die Athmosphäre ab­ gelassen werden muß.This leads to engines with the same power as in the uncharged Zu now stood to be able to build smaller things, which due to the smaller ones masses to be braked and braked when driving turn into one Saving fuel leads. The use of the energy contained in the exhaust gas However, such units, mostly exhaust gas turbochargers, cannot completely respectively. According to [1], a very small portion is sufficient in the usual motor driving cycle The engine fresh air often does not utilize the energy contained in the exhaust gas flow to compress enough. On the other hand, there is so much energy at full load Decree that this can no longer be used meaningfully and mostly via a device called "wastgate" to the atmosphere must be left.

Verbrennungsmotoren, insbesonders Ottomotoren, haben ihren verbrauchs­ optimalen Betriebspunkt im Bereich hoher Leistungsabgabe, also im unge­ drosselten Betrieb. In diesem Punkt fällt auch besonders viel Energie im Abgasstrom an, die hier nicht mehr genutzt werden kann. Im Fall des Ein­ satzes von Abgasturboladern wird ein Teil der Abgasenergie nutzbar, bei reinen Saugmotoren geht diese Energie verloren.Internal combustion engines, especially gasoline engines, have their consumption optimal operating point in the area of high power output, i.e. in the throttled operation. At this point a lot of energy falls in the Exhaust gas flow that can no longer be used here. In the case of the one exhaust gas turbochargers, part of the exhaust gas energy can be used at pure suction motors lose this energy.

Die Verwendung der im Abgas enthaltenen Energie kann nach [1] durch me­ chanische Wandlung selbiger in einer Nutzturbine und Aufschaltung auf die Abtriebswelle des Verbrennungsmotors erfolgen. Dabei kann die Nutzturbine im Verbundbetrieb mit einer Laderturbine betrieben werden oder auch allein. According to [1], the use of the energy contained in the exhaust gas can be determined by me chanic change of the same in a utility turbine and connection to the Output shaft of the internal combustion engine take place. The power turbine can be operated in conjunction with a turbocharger or alone.  

Die Anordnung der Nutzturbine im Verbund bezeichnet man als "Turbo­ compound". Bekannt sind die mechanische Nutzung der Energie durch Auf­ schaltung auf die Motorabtriebswelle und die Nutzung der Energie durch Wandlung in elektrische Energie in einer Nutzturbine ohne Verbundbetrieb [2].The arrangement of the utility turbine in the network is called "turbo compound ". The mechanical use of energy by Auf circuit to the motor output shaft and the use of energy Conversion into electrical energy in a utility turbine without combined operation [2].

Ebenfalls bekannt ist [3], daß die mechanische Energie von Wärmekraftma­ schinen direkt in Schwungmassenspeichern zwischengespeichert werden kann und zur Abdeckung von Energiebedarfsspitzen mit Energie aus einem peri­ odischem Betrieb eines Verbrennungsmotors herangezogen werden kann.It is also known [3] that the mechanical energy of thermal power ma machines can be buffered directly in flywheel storage and to cover energy demand peaks with energy from a peri odische operation of an internal combustion engine can be used.

Die Aufgabe der Erfindung besteht darin, die Verkopplung der Energieströme in einem System, insbesonders beim Hybridfahrzeug, zu erreichen, das mit­ tels einer Leistungsverzweigung die Energie des Abgasstromes je nach Bedarf und Angebot sowohl der Verdichterstufe des Turboladers, als auch einer ener­ giespeichernden Schwungmasse zugeführt werden kann.The object of the invention is to couple the energy flows in a system, especially with the hybrid vehicle, to achieve that with By means of a power split, the energy of the exhaust gas flow as required and offer both the compressor stage of the turbocharger and one can be fed to the flywheel.

Die erfindungsgemäße Lösung wird dadurch erreicht, indem die Schwung­ masse als integraler Bestandteil einer Elektromaschine (Läufer) in die Lage versetzt wird, die ihr innewohnende Energie in Elektroenergie, schaltbar je nach Bedarf, zu wandeln und abzugeben. Die Elektromaschine kann dabei als Generator und Motor arbeiten.The solution according to the invention is achieved by the momentum mass as an integral part of an electrical machine (rotor) is shifted, the inherent energy in electrical energy, switchable each to convert and deliver as needed. The electric machine can work as a generator and motor.

Da in Fahrzeugen bei Nutzung und Wandlung der dem Fahrzeug eigenen Be­ wegungsenergie, Bremsung durch Rückspeisung, ein Überangebot an Energie auftreten kann, ist die vorliegende Erfindung in der Lage, dieses Überangebot temporär zwischenzuspeichern. Dies geschieht durch Nutzung der Elektro­ maschine als Elektromotor, der die Rotormasse beschleunigt und somit die mechanische Energie der Schwungmasse erhöht. Since in vehicles when using and converting the vehicle's own loading Motion energy, braking through energy recovery, an oversupply of energy can occur, the present invention is able to overcome this oversupply store temporarily. This is done by using the electrical machine as an electric motor that accelerates the rotor mass and thus the mechanical energy of the flywheel increases.  

Damit eine Überhöhung der Drehzahl der Schwungmasse über die Drehzahl des Abtriebsstranges der Nutzturbine erfolgen kann, ist eine Kupplung (Frei­ lauf, Magnetkupplung, o. ä.) dahingehend vorgesehen, um ein automatisches oder gesteuertes Zuschalten nach Bedarf zu ermöglichen.Thus an increase in the speed of the flywheel over the speed of the drive train of the power turbine can take place, a clutch (free barrel, magnetic coupling, or the like) provided to an automatic or to enable controlled switching on as required.

Die bedarfsgerechte Zu- und Abschaltung des Schwungmassenspeichers und seine elektrische Kopplung ans Gesamtsystem führt zu einer Senkung der Schleppverluste und zu einer Verbesserung des Wirkungsgrades des Gesamt­ systems im Vergleich zu mechanisch angekoppelten Schwungmassenspeichern entsprechend dem Stand der Technik. The need-based connection and disconnection of the flywheel mass storage and its electrical coupling to the overall system leads to a reduction in Drag losses and to improve the overall efficiency systems compared to mechanically coupled flywheel mass storage systems according to the state of the art.  

Eine mögliche Ausführungsform der Erfindung wird anhand folgender Figur beschrieben:
Die energiereichen Abgase einer Verbrennungskraftmaschine (1) werden ei­ ner Anordnung aus Turbine mit verkoppeltem Verdichter (4) und verkop­ pelter Schwungmasse (5) zugeführt. Der Verdichter liefert an den Einlaß­ trakt der Verbrennungskraftmaschine (3) so viel komprimierte Luft, welche evtl. zusätzlich mittels eines Ladeluftkühlers gekühlt wird, wie im jeweiligen Betriebszustand des Verbrennungsmotors benötigt wird. Zusätzliche Ener­ gie der Turbinenabtriebswelle, die nicht mehr zum Verdichten der Ladeluft benötigt wird, wird über die Schaltkupplung (14) an die Schwungmasse (5) weitergeleitet und dort temporär als mechanische Energie gespeichert. Die­ se gespeicherte Energie kann, je nach Bedarf im Gesamtsystem, durch die Steuerungselektronik (10) kontrolliert, von der Elektromaschine (5), in deren Läufer die mechanische Energie gespeichert ist, in elektrische Energie gewan­ delt, von den leistungselektronischen Modulen (7) aufbereitet und über den Leistungsübertragungspfaden (6) den Verbrauchern (8, 9) oder Zwischenspei­ chern (12) zugeführt werden.A possible embodiment of the invention is described with reference to the following figure:
The high-energy exhaust gases of an internal combustion engine ( 1 ) are fed to an arrangement of a turbine with a coupled compressor ( 4 ) and a coupled flywheel ( 5 ). The compressor delivers to the inlet tract of the internal combustion engine ( 3 ) as much compressed air, which may be additionally cooled by means of a charge air cooler, as is required in the respective operating state of the internal combustion engine. Additional energy of the turbine output shaft, which is no longer required to compress the charge air, is passed on to the flywheel ( 5 ) via the clutch ( 14 ) and temporarily stored there as mechanical energy. The se stored energy can, as required in the overall system, controlled by the control electronics (10) of the electric machine (5), the mechanical energy stored in the rotor, Gewan punched into electrical energy, processed by the power electronic modules (7) and via the power transmission paths ( 6 ) to the consumers ( 8 , 9 ) or intermediate storage ( 12 ) are supplied.

Im Bremsbetrieb wird die an den im generatorschen Betrieb laufenden Ma­ schinen (8, 9) anfallende Energie über die Leistungsübertragungspfade (6) an die Leistungselektronik Module (7) weitergeleitet. Von dort aus wird die Energie dann über den Leistungsflupfad (11) in den Zwischenspeicher (12) und/oder den Schwungmassenspeicher (5) eingespeist und zwischengespei­ chert. Die Steuerstrategien der Umspeicherung der Energien ist in der Steue­ rungselektronik (10) abgelegt. In braking operation, the energy generated in the machines running in generator mode ( 8 , 9 ) is passed on to the power electronics modules ( 7 ) via the power transmission paths ( 6 ). From there, the energy is then fed via the power flow path ( 11 ) into the intermediate store ( 12 ) and / or the flywheel mass store ( 5 ) and buffered. The control strategies for the transfer of energy are stored in the control electronics ( 10 ).
