Description
Die Erfindung betrifft ein Fluideinspritzventil zum Einspritzen eines Fluids, das zumindest Wasser aufweist, in einen Brennraum einer Brennkraftmaschinenanordnung, mit einer Gehäuseanordnung, die zumindest ein Fluidzuführgehäuseteil und ein Antriebsgehäuseteil aufweist, in dem ein Ventilglied, das mittels einer Antriebseinrichtung antreibbar ist, beweglich gelagert ist, wobei das Ventilglied ein Ventilverschlussglied aufweist, das mit einer Durchströmöffnungsanordnung zusammenwirkt. Die Erfindung betrifft ebenfalls eine Brennkraftmaschinenanordnung mit einem derartigen Fluideinspritzventil.The invention relates to a fluid injection valve for injecting a fluid, which has at least water, into a combustion chamber of an internal combustion engine arrangement, with a housing arrangement which has at least one fluid supply housing part and a drive housing part in which a valve member which can be driven by means of a drive device is movably mounted, wherein the valve member has a valve closure member which cooperates with a throughflow opening arrangement. The invention also relates to an internal combustion engine arrangement with such a fluid injection valve.
Derartige Brennkraftmaschinenanordnungen sind aus dem Stand der Technik hinlänglich bekannt. Neben einer Brennstoffeinspritzanordnung, die geeigneten Brennstoff in den Brennraum einspritzt, ist ein Fluidspritzventil vorgesehen, das zumindest Wasser in den wesentlichen Verbrennungsluft führenden Einlasskanal spritzt. Hierdurch soll eine Kühlung des Verbrennungsgases und damit eine Wirkungsgradverbesserung erreicht werden. Beispiele hierfür sind bekannt aus der
Aufgabe der Erfindung ist es daher, ein Fluideinspritzventil sowie eine Brennkraftmaschinenanordnung bereitzustellen, die die oben genannten Nachteile auf einfache und kostengünstige Weise vermeidet.The object of the invention is therefore to provide a fluid injection valve and an internal combustion engine arrangement which avoid the above-mentioned disadvantages in a simple and inexpensive manner.
Diese Aufgabe wird dadurch gelöst, dass eine Elektrolyse-Anordnung in der Gehäuseanordnung vorgesehen ist, die zumindest einen Teil des Wassers in Wasserstoff- und Sauerstoffbestandteile aufspaltet. Hierdurch ist es möglich, die Vorteile der Elektrolyse mit der Wassereinspritzung zu kombinieren. Es findet hierdurch insbesondere ein Strahlaufbruch des Wasserstrahls statt, wodurch die Kühlwirkung mittels der Wassereinspritzung noch einmal erhöht werden kann. Zudem sind keine weiteren Bauteile notwendig, die im Motorenraum angeordnet werden müssen.This object is achieved in that an electrolysis arrangement is provided in the housing arrangement, which splits at least part of the water into hydrogen and oxygen components. This makes it possible to combine the advantages of electrolysis with water injection. In particular, this causes the water jet to break open, as a result of which the cooling effect can be increased again by means of the water injection. In addition, no further components are required that have to be arranged in the engine compartment.
In einer bevorzugten Ausführungsform sind eine Elektrolyse-Kathode und eine Elektrolyse-Anode der Elektrolyse-Anordnung im Antriebsgehäuseteil vorgesehen. Alternativ kann in vorteilhafter Weise die Elektrolyse-Kathode oder die Elektrolyse-Anode im Fluidzuführgehäuseteil vorgesehen sein.In a preferred embodiment, an electrolysis cathode and an electrolysis anode of the electrolysis arrangement are provided in the drive housing part. Alternatively, the electrolysis cathode or the electrolysis anode can advantageously be provided in the fluid supply housing part.
Alternativ kann die Elektrolyse-Kathode oder die Elektrolyse-Anode auch als ein metallisch ausgebildetes Filterelement ausgeführt sein.Alternatively, the electrolysis cathode or the electrolysis anode can also be designed as a metallic filter element.
In einer besonders vorteilhaften Ausführungsform ist die Antriebseinrichtung als ein Magnetaktuator ausgebildet, wobei das Ventilglied zumindest teilweise als Anker ausgebildet ist.In a particularly advantageous embodiment, the drive device is designed as a magnetic actuator, the valve member being at least partially designed as an armature.
Das Ventilglied kann eine Schließkugel als Ventilverschlussglied aufweisen. In besonders vorteilhafter Weise ist die Durchströmöffnungsanordnung als Spritzlochscheibe ausgeführt. Das feine Wasserspray kann hierdurch besonders effektiv verteilt werden.The valve member can have a closing ball as a valve closure member. In a particularly advantageous manner, the throughflow opening arrangement is designed as a spray perforated disk. This allows the fine water spray to be distributed particularly effectively.
Die Erfindung wird ebenfalls gelöst, durch eine Brennkraftmaschinenanordnung mit mindestens einem Zylinderblock, in dem mindestens ein Zylinder vorgesehen ist, und mindestens einem Zylinderkopf, wobei in dem Zylinder ein Brennraum vorgesehen ist, der durch einen Kolben und den Zylinderkopf begrenzt ist, wobei in dem Zylinderkopf eine Einlasskanalanordnung mit mindestens einem Einlassventil und eine Auslasskanalanordnung mit mindestens einem Auslassventil vorgesehen sind, wobei des Weiteren eine Fluidzulaufanordnung vorgesehen ist, um Fluid, das zumindest Wasser aufweist, über zumindest ein erfindungsgemäß ausgebildetes Fluideinspritzventil in den Brennraum zu führen.The invention is also achieved by an internal combustion engine arrangement with at least one cylinder block, in which at least one cylinder is provided, and at least one cylinder head, wherein a combustion chamber is provided in the cylinder, which is delimited by a piston and the cylinder head, wherein in the cylinder head an inlet duct arrangement with at least one inlet valve and an outlet duct arrangement with at least one outlet valve are provided, furthermore a fluid inlet arrangement is provided in order to guide fluid, which has at least water, into the combustion chamber via at least one fluid injection valve designed according to the invention.
Hierbei kann es vorteilhaft sein, dass in der Fluidzulaufanordnung mindestens eine zusätzliche Elektrolyse-Anordnung vorgesehen ist.It can be advantageous here for at least one additional electrolysis arrangement to be provided in the fluid inlet arrangement.
Auch kann es vorteilhaft sein, dass im Zylinderkopf eine integrierte Wasserrail mit einem Fluidanschluss vorgesehen ist, die fluidisch mit den Fluideinspritzventilen verbunden ist. Alternativ ist es natürlich auch denkbar, eine separate Wasserrail vorzusehen, die auf dem Zylinderkopf aufgesetzt ist.It can also be advantageous for an integrated water rail with a fluid connection to be provided in the cylinder head, which is fluidically connected to the fluid injection valves. Alternatively, it is of course also conceivable to provide a separate water rail that is placed on the cylinder head.
