Abstract
Description
Die Erfindung betrifft ein Kraftstoffeinspritzsystem für Kraftstoff, aufweisend ein Niederdrucksystem mit einem Tank und einer Niederdruckpumpe, sowie eine Wasserbevorratungseinrichtung und eine Vorrichtung zur Beimischung von Wasser zu dem Kraftstoff. The invention relates to a fuel injection system for fuel, comprising a low-pressure system with a tank and a low-pressure pump, and a water storage device and a device for adding water to the fuel.
Stand der Technik State of the art
Ein derartiges Kraftstoffeinspritzsystem für Kraftstoff ist aus der
Der Erfindung liegt die Aufgabe zugrunde, ein Kraftstoffeinspritzsystem mit einer Vorrichtung zur Beimischung von Wasser zu dem Kraftstoff bereitzustellen, mit dem eine stabile Kraftstoff-Wasser-Emulsion erzeugt werden kann. The invention has for its object to provide a fuel injection system with a device for adding water to the fuel, with which a stable fuel-water emulsion can be produced.
Offenbarung der ErfindungDisclosure of the invention
Vorteile der ErfindungAdvantages of the invention
Diese Aufgabe wird dadurch gelöst, dass die Vorrichtung eine Ultraschalleinrichtung ist, und dass die Ultraschalleinrichtung mit einer in das Kraftstoffeinspritzsystem integrierten Mischkammer zusammenwirkt. Mit einer Ultraschalleinrichtung kann eine zumindest über mehrere Stunden stabile Kraftstoff-Wasser-Emulsion erzeugt werden. Dabei wird dem Kraftstoff unmittelbar vor oder in einer den Kraftstoffeinspritzsystem zugeordneten Einspritzvorrichtung die gewünschte Wassermenge zudosiert und mit der Ultraschalleinrichtung in eine über Stunden stabile Emulsion gebracht. Diese Emulsion wird dann über die konventionelle Einspritzvorrichtung direkt in ein beliebiges System eingespritzt. Betriebspunktabhängig kann dabei der Wassergehalt der Emulsion in weiten Bereichen variiert werden.This object is achieved in that the device is an ultrasonic device, and that the ultrasonic device cooperates with a mixing chamber integrated in the fuel injection system. An ultrasound device can be used to generate a fuel-water emulsion that is stable for at least several hours. In this case, the fuel is added to the fuel immediately before or in a fuel injection system associated with the desired amount of water and brought with the ultrasonic device in an hourly stable emulsion. This emulsion is then injected directly into any system via the conventional injector. Depending on the operating point, the water content of the emulsion can be varied within wide ranges.
Insbesondere bei der Verbrennung von Dieselkraftstoff entstehen Stickoxide und Rußpartikel. Diese Rußpartikel können über einen Rußfilter aus dem Abgas ausgeschieden und beispielsweise verbrannt werden. Die Vermeidung von Stickoxiden kann durch eine Verbesserung der Gemischaufbereitung vor der Verbrennung erreicht werden. Dies ist aber mit steigendem Einspritzdruck und damit erhöhtem Aufwand für das Kraftstoffeinspritzsystem verbunden. Zudem muss die Energie für den hohen Druck aufgebracht werden, was wiederum den Verbrauch des Kraftstoffeinspritzsystems erhöht. Alternativ kann auch ein Betriebspunkt im Stickoxid/Ruß-Emissionsdiagramm gewählt werden, bei dem niedrige Stickoxidemissionen auf Kosten von erhöhter Rußemissionen erreicht werden. Wenn auch die Rußemissionen durch den Einsatz eines Partikelfilters eliminiert werden können, ist dieses System mit einem höheren Verbrauch verbunden. In particular, the combustion of diesel fuel produces nitrogen oxides and soot particles. These soot particles can be eliminated via a soot filter from the exhaust gas and burned, for example. The avoidance of nitrogen oxides can be achieved by improving the mixture preparation before combustion. However, this is associated with increasing injection pressure and thus increased effort for the fuel injection system. In addition, the energy for the high pressure must be applied, which in turn increases the consumption of the fuel injection system. Alternatively, an operating point in the nitrogen oxide / soot emission diagram can be selected in which low nitrogen oxide emissions are achieved at the expense of increased soot emissions. Although soot emissions can be eliminated by using a particulate filter, this system requires more fuel.
Durch die Beigabe von Wasser zusammen mit dem Kraftstoff in den Brennraum oder eine Brennkammer, kann die Temperatur bei der Verbrennung abgesenkt werden, so dass die Stickoxidentstehung reduziert oder vermieden wird. Dadurch kann alternativ bei gleicher Stickoxidemission im Vergleich zu herkömmlichen Brennverfahren der Verbrauch gesenkt werden. By adding water together with the fuel in the combustion chamber or a combustion chamber, the temperature can be lowered during combustion, so that the nitrogen oxide formation is reduced or avoided. As a result, the consumption can be reduced alternatively with the same nitrogen oxide emission compared to conventional combustion processes.
Die Beigabe von Wasser in den Brennraum oder die Brennkammer kann auch durch eine direkte Einspritzung in den Brennraum bzw. die Brennkammer erfolgen. Nachteil dieser Methode ist es aber, das zu dem Kraftstoffeinspritzsystem ein weiteres System für die Einspritzung von Wasser vorhanden sein muss, wobei zudem bei einer Benetzung der Brennraumwände oder der Brennkammerwände mit Wasser beispielsweise Korrosion auftreten kann. The addition of water into the combustion chamber or the combustion chamber can also be effected by direct injection into the combustion chamber or the combustion chamber. Disadvantage of this method, however, is that to the fuel injection system, a further system for the injection of water must be present, in addition, when wetting the combustion chamber walls or the combustion chamber walls with water, for example, corrosion may occur.
Alternativ kann aber mit einem konventionellen Kraftstoffeinspritzsystem beziehungsweise dessen Einspritzvorrichtung eine Kraftstoff-Wasser-Emulsion dann eingespritzt werden, wenn diese stabil ist. Stabil bedeutet, dass die Emulsion zumindest für den Zeitraum, in dem diese in den Brennraum bzw. die Brennkammer eingespritzt wird, ohne Zersetzungsgefahr, aufrechterhalten wird. Dies ist gemäß dem Stand der Technik nur durch Zugabe eines Emulgators möglich, der eine Lagerung der Emulsion auch über eine längere Zeit in der Größenordnung von zumindest mehreren Tagen ermöglicht. Nachteilig ist, dass der in einem Behälter zu bevorratende Emulgator den Emissionsvorschriften genügen muss und gegebenenfalls die Emissionen deutlich verschlechtern kann. Schließlich kann bei einer solchen vorgefertigten Emulsion der Wassergehalt nicht individuell beispielsweise betriebspunktabhängig an die Erfordernisse angepasst werden. Alternatively, however, with a conventional fuel injection system or its injection device, a fuel-water emulsion can then be injected if it is stable. Stable means that the emulsion is maintained at least for the period in which it is injected into the combustion chamber or the combustion chamber, without risk of decomposition. This is possible according to the prior art only by adding an emulsifier, which allows storage of the emulsion over a longer time on the order of at least several days. The disadvantage is that the emulsifier to be stored in a container has to comply with emission regulations and, if appropriate, can markedly reduce emissions. Finally, with such a prefabricated emulsion, the water content can not be adjusted individually to the requirements, for example, depending on the operating point.
Durch die erfindungsgemäße Ausgestaltung der Vorrichtung als Ultraschalleinrichtung, die mit einer in das Kraftstoffeinspritzsystem integrierten Mischkammer zusammenwirkt, lassen sich die geschilderten Nachteile allesamt ausschalten und eine über einen längeren Zeitraum stabile Kraftstoff-Wasser-Emulsion erzeugen, bei der der Wassergehalt in weiten Grenzen betriebspunktabhängig veränderbar ist. Dabei ist der Bauaufwand für die Vorrichtung im Vergleich zu anderen Systemen überschaubar.Due to the inventive design of the device as an ultrasonic device, which is integrated with a in the fuel injection system Mixing chamber cooperates, the disadvantages can all turn off and produce a stable over a longer period of fuel-water emulsion, in which the water content is variable depending on operating point dependent. The construction cost of the device compared to other systems manageable.
In Weiterbildung der Erfindung ist die Ultraschalleinrichtung eine Ultraschallsonde oder in alternativer Ausgestaltung ein Ultraschallpulser. Mit solchen Ultraschalleinrichtungen lässt sich eine stabile Kraftstoff-Wasser-Emulsion besonders vorteilhaft erzeugen. Dabei wird bei beiden Ultraschalleinrichtungen das Wasser in die Mischkammer dosiert eingegeben und von der Ultraschalleinrichtung wird das Wasser mit dem Kraftstoff in eine stabile Emulsion gebracht. In a development of the invention, the ultrasound device is an ultrasound probe or, in an alternative embodiment, an ultrasound pulse. With such ultrasonic devices, a stable fuel-water emulsion can be produced particularly advantageously. In this case, in both ultrasonic devices, the water is metered into the mixing chamber and the ultrasound device brings the water with the fuel into a stable emulsion.
In Weiterbildung der Erfindung weist die Kraftstoffeinspritzvorrichtung ein Hochdrucksystem mit einer Hochdruckpumpe auf und die Ultraschalleinrichtung und die Mischkammer sind in Strömungsrichtung vor dem Hochdrucksystem angeordnet oder alternativ sind sie Bestandteil des Hochdrucksystems. Die Anordnung der Mischkammer vor dem Hochdrucksystem hat den Vorteil, dass das Wasser nur unter dem geringen Druck des Niederdrucksystems in die Mischkammer eingebracht werden muss. Wird das Wasser aber in das Hochdrucksystem eingebracht, muss das Wasser entsprechend dem in dem Hochdrucksystem herrschenden Druck gefördert bzw. eingebracht werden. Andererseits hat dieses System den Vorteil, dass die Möglichkeit eines Kontakts mit beispielsweise korrosionsgefährdeten Teilen des vorgeschalteten Hochdrucksystems gering ist.In a development of the invention, the fuel injection device has a high-pressure system with a high-pressure pump, and the ultrasonic device and the mixing chamber are arranged upstream of the high-pressure system in the flow direction or alternatively they are part of the high-pressure system. The arrangement of the mixing chamber before the high pressure system has the advantage that the water must be introduced only in the mixing chamber under the low pressure of the low pressure system. However, if the water is introduced into the high-pressure system, the water must be conveyed or introduced in accordance with the pressure prevailing in the high-pressure system. On the other hand, this system has the advantage that the possibility of contact with, for example, corrosion-prone parts of the upstream high-pressure system is low.
In weiterer Ausgestaltung ist vorgesehen, dass das Hochdrucksystem eine kraftstoffgeschmierte Hochdruckpumpe aufweist und dass die Mischkammer dem Schmiersystem der Hochdruckpumpe nachgeschaltet ist. Durch diese Ausgestaltung wird eine nachteilige Beeinflussung des gesamten Schmiersystems vermieden. Dabei kann die Mischklammer aber noch vor dem eigentlichen Hochdrucksystem angeordnet sein.In a further embodiment, it is provided that the high-pressure system has a fuel-lubricated high-pressure pump and that the mixing chamber is connected downstream of the lubrication system of the high-pressure pump. By this configuration, an adverse effect on the entire lubrication system is avoided. However, the mixing bracket can still be arranged before the actual high-pressure system.
In Weiterbildung der Erfindung ist das Hochdrucksystem Bestandteil einer Brennkraftmaschine und der Kraftstoff ist Dieselkraftstoff. Insbesondere bei einer solchen Anwendung in Verbindung mit einem Common Rail Einspritzsystem ist der Gegenstand der Erfindung vorteilhaft umsetzbar. In a further development of the invention, the high-pressure system is part of an internal combustion engine and the fuel is diesel fuel. In particular, in such an application in conjunction with a common rail injection system, the subject of the invention is advantageously implemented.
Alternativ ist in weiterer Ausgestaltung das Kraftstoffeinspritzsystem ein Brenner, beispielsweise ein Brenner zum Anbau an eine Regenerationseinrichtung für einen Rußfilter. Der Brenner kann aber auch ein beliebiger sonstiger mit einem Dieselkraftstoff oder Öl, insbesondere Heizöl betriebener Brenner sein, der beispielsweise in einer Heizungsanlage eingesetzt wird. Alternatively, in another embodiment, the fuel injection system is a burner, for example a burner for mounting on a regeneration device for a soot filter. However, the burner can also be any other burner operated with a diesel fuel or oil, in particular fuel oil, which is used, for example, in a heating system.
In Weiterbildung der Erfindung weist das Kraftstoffeinspritzsystem eine Einspritzvorrichtung, die beispielsweise Kraftstoffinjektoren aufweisen kann, auf und die Einspritzvorrichtung weist zudem einen Wasserabscheider auf. Ein solcher Wasserabscheider wird vorgesehen, wenn die Möglichkeit besteht, dass die Wasser-Brennstoff-Emulsion über einen längeren Zeitraum in dem Kraftstoffeinspritzsystem beispielsweise im Rahmen einer Abstellung verbleibt oder aber wenn die Einspritzvorrichtung einen Leckagestrom aufweist, der in den Tank zurückgeführt wird. In einem solchen Fall wird dann das Wasser aus der Emulsion herausgetrennt, so dass in den Tank nur Kraftstoff zurückgeführt wird. In a further development of the invention, the fuel injection system has an injection device, which may have fuel injectors, for example, and the injection device also has a water separator. Such a water separator is provided if there is the possibility that the water-fuel emulsion remains in the fuel injection system for a longer period of time, for example, in the context of shutdown or if the injection device has a leakage flow, which is returned to the tank. In such a case, the water is then separated from the emulsion, so that only fuel is returned to the tank.
