Description

Einrichtung zur Speisung des elektrischen Bordnetzes von Kraftfahrzeugen Die Erfindung betrifft eine Einrichtung zur Speisung des elektrischen Bordnetzes von Fahrzeugen mit Brennkraftmaschinen, insbesondere von Kraftfahrzeugen, bestehend aus einem Stromerzeuger, einer Speicherbatterie und den Stromverbrauchern sowie den entsprechenden Schaitmitteln.Device for feeding the electrical system of motor vehicles The invention relates to a device for feeding the electrical system of vehicles with internal combustion engines, in particular of motor vehicles from a power generator, a storage battery and the power consumers as well the corresponding switching means.

An die Bordnetze der obenerwähnten Fahrzeuge sind üblicherweise verschiedene Verbraucher, wie z. B. Beleuchtung, Anlasser, Lüftung, Zündung, Einspritzanlage und u. U. auth noch Nebengeräte, wie z. fl. Radiosangeschlossen. Das Bordnetz wird in derartigen Fahrzeugen üblicherweise von der Brennkraftmeschine mit Hilfe eines Generators, d. h. der Lichtmaschine gespeist, wobei eine Batterie als Speicher eingeschaltet ist. Diese bekannten Einrichtungen stellen an sich einen technischen Umweg dar und sie haben insofern eine ganze Reihe von Nach'-teilen. Hier wäre in erster Linie der Verschleiß und die Geräusche des mechanischen Antriebs der Lichtmaschine sowie der Raumbedarf für einen derartigen Antrieb zu nennen.The on-board networks of the above-mentioned vehicles are usually different Consumers such as B. lighting, starter, ventilation, ignition, injection system and possibly also secondary devices, such as fl. radio connected. The electrical system is in such vehicles usually from the internal combustion engine with the help of a Generator, d. H. powered by the alternator, with a battery switched on as a memory is. These known facilities are in themselves a technical detour and To this extent they have a number of disadvantages. Here would be in the first place the wear and tear and noise of the mechanical drive of the alternator as well to name the space required for such a drive.

Der Erfindung liegt die Aufgabe zugrunde, diese Nachteile zu vermeiden. D. h., es soll eine Einrichtung vorgeschlagen werden, mit der eine unmittelbare Speisung des elektrischen Bordnetzes ohne den technischen Umweg über die mechanische Arbeit möglich ist. Dabei soll naturgemäß auch der erforderliche Raumbedarf möglichst noch herabgesetzt werden.The invention is based on the object of avoiding these disadvantages. That is, a device is to be proposed with which an immediate Supply of the on-board electrical system without the technical detour via the mechanical one Work is possible. Naturally, the space required should also be as large as possible still to be reduced.

Diese Aufgabe wird bei den eingangs genannten Einrichtungen gemäß der Erfindung dadurch gelöst, daß als Stromerzeuger ein von den Abgasen der Brerinkraftmaschine betriebener thermionischer Wandler dient. Auf diese Weise ist eine direkte Umwandlung der in den Abgasen noch vorhandenen Wärmeenergie in elektrische Energie möglich, ohne daß die vorstehend geschilderten Nachteile auftreten können. Thermionische Wandler basieren auf dem Effekt der thermischen Emission von Elektronen aus einer heißen Elektrode, und haben nach den heutigen Stand bereits Wirkungsgrade, die für den vorliegenden Anwendungsfall gut ausreichen. Unter Umständen läßt sich der Wirkungsgrad noch so steigern, daß man einen Elektromotor als Fahrzeugantrieb - parallel zur Brennkraftmaschine - vorsehen kann, der zumindest im Teilbetrieb unter Inanspruchnahme der Speicherbatterie aus dem Bordnetz betrieben werden kann. Durch den thermionischen Wandler ist dann eine schnelle Wiederaufladung der Speicherbatterie gewährleistet.This task is in accordance with the facilities mentioned above the invention achieved in that as a power generator one of the exhaust gases from the Brerin engine powered thermionic Converter is used. This way is one direct conversion of the thermal energy still present in the exhaust gases into electrical energy Energy possible without the disadvantages described above can occur. Thermionic converters are based on the effect of the thermal emission of electrons from a hot electrode, and according to the current state of the art already have efficiencies, which are sufficient for the application at hand. Under certain circumstances can Increase the efficiency so that you can use an electric motor as a vehicle drive - In parallel with the internal combustion engine - can provide, at least in partial operation can be operated using the storage battery from the on-board network. The thermionic converter then enables the storage battery to be recharged quickly guaranteed.

Mit der Erfindung wird vorgeschlagen, daß in dem bzw. den Auspuffrohren bzw. Auspuffkanäien (rer Brennkraftmaschine möglichst nahe benachbart zu dieser Thermionik-Elemente angeordnot sind, deren Emitter vom Abgasstrom überstrichen werden.With the invention it is proposed that in the exhaust pipe or pipes or Auspuffkanäien (rer internal combustion engine as close as possible to this Thermionic elements are arranged, the emitters of which are swept over by the exhaust gas flow.

Hierbei ist im Prinzip die Anordnung im Auspuff-Sammelrohr, an jedem Zylinder einzeln und auch in einem gemeinsamen Auspuffdämpfer möglich. Ebenfalls wäre die Anordnung in einem Nachverbrenner denkbar, sofern ein solcher zur Abgas-Entgif tung vorhanden ist.In principle, this is the arrangement in the exhaust manifold, on each Cylinders individually and also in a common exhaust silencer possible. Likewise an arrangement in an afterburner would be conceivable, provided one is used for exhaust gas detoxification tion is available.

Die Erfindung bevorzugt jedoch eine Lösung, wonach im Zylinderkopf in jedem Auslaßkanal unmittelbar neben dem Auslaßventil ringförmige Thermionikelemente angeordnet sind, deren Kollektoren elektrisch isoliert, fest im Zylinderkopf sitzen und über Isolierstücke, die konzentrisch innerhalb jedes Kollektors angeordneten ringförmigen Emitter tragen. Die beiden konzentrischen Elektrodenflächen liegen sich dabei mit möglichst kleinem Abstand genau gegenüber. Ein weiteres Merkmal der Erfindung wird darin gesehen, daß der Emitter an seinem inneren Umfang zur Wärmeaufna'1me eine vergößerte Oberfläche aufweist, z. B. in Strömungsrichtung verrippt ist. Da in Strömungsrichtung gesehen mehrere Thermionikelemente hintereinander liegen, kann es zweckmäßig sein, wenn die Rippen der einzelnen Elemente gegeneinander versetzt sind, indem einfach die entsprechenden Ringelemente gegeneinander verdreht sind.However, the invention prefers a solution, according to which in the cylinder head in each outlet channel immediately next to the outlet valve, annular thermionic elements are arranged, whose collectors are electrically insulated, sit firmly in the cylinder head and via insulating pieces arranged concentrically within each collector wear ring-shaped emitter. The two concentric electrode surfaces lie exactly opposite each other with the smallest possible distance. Another feature of the Invention is seen in the fact that the emitter on its inner circumference for heat absorption has an enlarged surface, e.g. B. is ribbed in the flow direction. There Seen in the direction of flow, several thermionic elements can lie one behind the other it may be useful if the ribs of the individual elements against each other are offset by simply twisting the corresponding ring elements against each other are.

Es wird weiter vorgeschlagen, daß die einzelnen Thermionik-Elemente elektrisch voneinander isoliert sind und ggf. an jedem Element der Zwischenraum zwischen dem Emitter und dem Kollektor mit Gas gefüllt ist. Durch eine solche Gasfüllung läßt sich der Wirkungsgrad erhöhen. Ein weiteres Merkmal der Erfindung ist darin zu sehen, daß untereinander gleiche Thermionikelemente verwendet werden und davon so viel elektrisch in Reihe geschaltet sind, daß die gesamte Ausgangsspannung der Ladespannung der Speicherbatterie entspricht. Man kann di e die hintereintndergeschalteten Thermionik-Elemente zu kompletten Baueinheiten zusammenfassen, die dann einheitlich in die Auspuffrohre einsetzbar sind oder ggf.It is also proposed that the individual thermionic elements are electrically isolated from each other and, if necessary, the space on each element between the emitter and the collector is filled with gas. By such a gas filling the efficiency can be increased. Another feature of the invention is therein to see that the same thermionic elements are used and of them so much are electrically connected in series that the total output voltage of the Corresponds to the charging voltage of the storage battery. You can use the one behind the other Combine thermionic elements into complete structural units, which are then uniform can be inserted into the exhaust pipes or

auch als Zwischenflansch ausgeführt werden und zwischen dem Zylinderkopf und den Auspuffkriimmern eingesetzt werden können.can also be designed as an intermediate flange and between the cylinder head and the exhaust fringes can be used.

Die Leistungsausbeute wird durch Drehzahl und Mitteldruck der Brennkraftmaschine wesentlich beeinflußt, da die Abgas~ temperatur und die Wärmemenge keinesfalls konstant ist. Für eine Regelung - insbesondere um ein Überladen der Batterie bei langen Vollastfahrten zu verhindern - wäre eine Temperatursenkung am Emitter, z. B. durch Frischluftbeimengung oder eine Temperturerhöhung am Kollektor prinzipiell denkbar.The power output is determined by the speed and mean pressure of the internal combustion engine has a significant influence, since the exhaust gas temperature and the amount of heat are by no means constant is. For a regulation - especially to avoid overcharging the battery during long full-load journeys to prevent - would be a temperature reduction at the emitter, z. B. by adding fresh air or an increase in temperature at the collector is conceivable in principle.

Auch eine Spannungsregelung durch An- oder Abschalten einzelner Elemente läßt sich anwenden, sodaß der Spannungsunterschied zwischen der Ausgangsspannung der Thermionikelemente und der Speicherbatterie verringert oder zu Null wird.Voltage regulation by switching individual elements on or off can be applied so that the voltage difference between the output voltage of the thermionic elements and the storage battery decreases or goes to zero.

Einzelheiten der Erfindung zeigt das Ausführungsbeispiel der Zeichnung und zwar zeigt: Fig. 1 die Anordnung der Thermionik-Elemente im Zylinderkopf im Schnitt, Fig. 2 eine vergrößerte Schnittdarstellung der Thermionikelemente gemäß Fig. 1 und Fig. 3 ein einzelnes Thermionikelement gemäß Fig. 2 in Ansicht.Details of the invention are shown in the exemplary embodiment in the drawing namely shows: Fig. 1 the arrangement of the thermionic elements in the cylinder head in Section, FIG. 2 shows an enlarged sectional view of the thermionic elements according to FIG FIGS. 1 and 3 show a single thermionic element according to FIG. 2 in a view.

Nach Fig. 1 befindet sich im Zylinderkopf 10 unmittelbar neben dem Auslaßventil 11 eine Reihe von Thermionikelementen 12, die von heißen Abgasen durchströmt werden. Die Abgase werden dann durch den Krümmer 13 zum nicht mehr dargestellten AuspuffsammelroIr weitergeleitet. Dabei sind so viel einzelne Thermionikelemcnte vorgesehen, daß deren gesamte Ausgangs spannung der Ladespannung der Speicherbatterie entspricht.According to Fig. 1 is located in the cylinder head 10 immediately next to the Outlet valve 11 is a series of thermionic elements 12 through which hot exhaust gases flow will. The exhaust gases are then no longer shown through the manifold 13 Exhaust manifold forwarded. There are so many individual thermionicle components provided that the total output voltage of the charging voltage of the storage battery is equivalent to.

Im vorliegenden Fall sind sechs einzelne Thermionikelemente 12 vorgesehen, wie insbesondere die Figur 2 klar erkennen läßt. Zur Ausnahme dieser Elemente 12 ist der Auspuffkanal 14 mit einer Erweiterung 15 versehen, in welche die einzelnen Thermionikelemente eingesetzt sind. Die li E Elemente sind untereinander alle gleich, so daß nur eines tnlland der Figuren 2 und 3 beschrieben zu werden braucht.In the present case, six individual thermionic elements 12 are provided, as can be seen particularly clearly in FIG. To the exception of these elements 12 the exhaust duct 14 is provided with an extension 15 in which the individual Thermionic elements are used. The li E elements are all equal to each other, so that only one country of FIGS. 2 and 3 needs to be described.

Jenes Thermionikelement 12 besteht aus einem ringförmigen Kollektor i6, der elektrisch isoliert fest in der Erweiterung 15 es Zylinderkopfes 10 sitzt. Dieser ringfö. mige Kollektor 16 nimmt den konzentrisch dazu innen angeordneten ringförmigen Emitter 17 auf, wobei Zwischenstücke 18 den gegenseitigen Abstand der einander genau gegeniiberliesellden Electrodenflachen garantieren. Der Emitter 18 ist innen mit Rippen 19 versehen, die parallel zum Abgasstrom verlaufen. Diese dienen zur besseren Wärmeaufnahme.That thermionic element 12 consists of an annular collector i6, which is firmly seated in the extension 15 of the cylinder head 10 in an electrically insulated manner. This ringfö. Mige collector 16 takes the concentrically arranged inside annular emitter 17, with spacers 18 the mutual spacing of the guarantee that the electrode surfaces lie exactly opposite one another. The emitter 18 is provided with ribs 19 on the inside, which run parallel to the exhaust gas flow. These serve for better heat absorption.

Alle Thermionikelemente 12 sind untereinander und gegen die Wandungen des Zylinderkopfes elektrisch isoliert und diese Isoliermesse 20 dient zugleich zur Aufnahme der elektrischen Verbindungen zwischen den einzelnen Thermionikelementen.All thermionic elements 12 are against each other and against the walls of the cylinder head electrically insulated and this Isoliermesse 20 serves at the same time to accommodate the electrical connections between the individual thermionic elements.

Diese sind - wic bereits erwähnt - in Reihe gesdialtet, so daß sich im vorliegenden Fall eine Ausgangsspannung für die gesamte Anordnung von etwa 6 Volt ergibt. Am Ende der gesamten Anordnung bildet die Isoliermasse eine Art Flansch 21, deren Ansatz 22 die elektrischen Ableitungen 23 enthält.These are - as already mentioned - dialed in series so that in the present case an output voltage for the entire arrangement of approximately 6 Volts results. At the end of the entire arrangement, the insulating compound forms a kind of flange 21, the approach 22 of which contains the electrical conductors 23.

Zwischen dem Zylinderkopf 10 und dem Auspuffkrümmer 13 ist in bekannter Weise eine Dichtung 24 angeordnet.Between the cylinder head 10 and the exhaust manifold 13 is known in Way a seal 24 is arranged.

Es wird zlçeckmaßig sein, die einzelnen Thermionik-Elemente 12 gegeneinander geringfügig zu verdrehen, so daß die Rippen 19 nicht fluchtend hintereinander liegen. Es wäre auch deXcbar, die Rippen schraubenförmig auszubilden, wie überhaupt auch jede andere Oberflächenvergrößerung an der inneren Seite des Emitters brauchbar ist, solange sie den Abgasstrom nicht allzusehr behindert.It will be square, the individual thermionic elements 12 against each other to twist slightly so that the ribs 19 are not aligned one behind the other. It would also be possible to make the ribs helical, as well as in general any other surface enlargement on the inner side of the emitter can be used is as long as it does not impede the flow of exhaust gas too much.
