Description
Die Erfindung betrifft ein Verfahren zum Demineralisieren oder Deionisieren von Wasser in einem Kraftfahrzeug, das einen Wassertank und eine geeignete Aufbereitungsvorrichtung für Wasser, welches einem Verbrennungsmotor oder einer anderen Fahrzeug-Vorrichtung in demineralisierter oder deionisierter Form zuzuführen ist, aufweist. Ferner betrifft die Erfindung eine entsprechende Vorrichtung.The invention relates to a method for demineralizing or deionising water in a motor vehicle, comprising a water tank and a suitable treatment device for water, which is to be supplied to a combustion engine or other vehicle device in demineralized or deionized form. Furthermore, the invention relates to a corresponding device.
Zur Erfüllung künftiger Abgasgrenzwerte von Verbrennungsmotoren in Kraftfahrzeugen kann eine Beimengung von Wasser zur Ansaugluft oder eine Wassereinspritzung in den Brennraum hilfreich sein, wobei jedoch demineralisiertes oder deionisiertes Wasser zu verwenden ist. Dieses wird ebenso wie der zu verbrennende Kraftstoff in einem Tank im Kraftfahrzeug mitgeführt, welcher Tank immer wieder zu befüllen ist. Auch wenn beispielsweise vorgesehen ist, dass dieser Tank nur mir demineralisierten Wasser befüllt werden kann oder soll, kann es vorkommen, dass Verunreinigungen oder verunreinigtes Wasser in den Tank gelangt. Dies müsste dann eigentlich aus dem Tank entfernt und der Tank geeignet gespült werden, was keinem Nutzer eines Kraftfahrzeugs zuzumuten ist.To meet future exhaust emission limits of internal combustion engines in automobiles, it may be helpful to add water to the intake air or to inject water into the combustion chamber, but using demineralized or deionized water. This is like the fuel to be burned carried in a tank in the vehicle, which tank is always to fill. Even if, for example, it is provided that this tank can or should only be filled with demineralized water, it can happen that impurities or contaminated water get into the tank. This would then actually have to be removed from the tank and the tank to be flushed properly, which is not expected to be a user of a motor vehicle.
Daher ist es Aufgabe der vorliegenden Erfindung, eine Abhilfemaßnahme für einen solchen Fall aufzuzeigen. Die Lösung dieser Aufgabe ergibt sich mit den Merkmalen des Anspruchs 1; vorteilhafte Weiterbildungen sowie eine Vorrichtung zur Durchführung des Verfahrens sind Inhalt der weiteren Ansprüche.Therefore, it is an object of the present invention to provide a remedial measure for such a case. The solution to this problem arises with the features of claim 1; advantageous developments and an apparatus for carrying out the method are content of the other claims.
Geeignete Aufbereitungsvorrichtungen zur Demineralisierung von Wasser sind grundsätzlich bekannt. Beispielsweise sei hier eine Umkehrosmose-Vorrichtung genannt, welcher neben einer mechanischen Filtereinheit ein Aktivkohlefilter zur Vermeidung von chemischen Beschädigungen vorgeschaltet sein kann. Eine solche oder eine andere geeignete Aufbereitungsanlage sei nun vorgesehen, wobei selbstverständlich auch geeignete Leitungen, gegebenenfalls mit geeignet schaltbaren Ventilen, sowie zumindest eine Fördervorrichtung zum Fördern von Wasser aus dem Wasser-Tank vorhanden sind. Erfindungsgemäß wird nun selbsttätig Wasser aus dem Wassertank entnommen und durch die Aufbereitungsvorrichtung geführt und daraufhin (nach Art eines Nebenstroms) in den Wassertank zurückgeführt. Es wird somit nicht nur Wasser mit der Fördervorrichtung aus dem Tank zu geeigneten Einspritzventilen geführt, durch welche das Wasser dosiert der Ansaugluft des Verbrennungsmotors beigemengt oder direkt in die Brennräume des Motors eingespritzt wird, sondern es wird Wasser aus dem Tank durch die genannte Aufbereitungsvorrichtung und danach wieder in den Tank zurückgeführt. Letzteres erfolgt selbsttätig in Abhängigkeit von bestimmten Randbedingungen und wird von einer elektronischen Steuereinheit entsprechend veranlasst bzw. gesteuert. Selbstverständlich kann auch jenes Wasser, welches einem oder den vorstehend genannten Einspritzventil(en) zugeführt wird, zuvor durch die ohnehin vorhandene Aufbereitungsvorrichtung geführt werden.Suitable treatment devices for demineralizing water are known in principle. For example, a reverse osmosis device may be mentioned here which, in addition to a mechanical filter unit, may be preceded by an activated carbon filter to prevent chemical damage. Such or another suitable treatment plant is now provided, of course, suitable lines, possibly with suitably switchable valves, and at least one conveying device for conveying water from the water tank are available. According to the invention, water is automatically removed from the water tank and passed through the treatment device and then returned (in the manner of a secondary stream) into the water tank. It is thus not only water with the conveyor out of the tank to suitable injectors, through which the metered water is added to the intake air of the engine or injected directly into the combustion chambers of the engine, but it is water from the tank through said processing device and thereafter returned to the tank. The latter takes place automatically as a function of certain boundary conditions and is initiated or controlled by an electronic control unit. Of course, that water, which is supplied to one or the above-mentioned injection valve (s), previously be performed by the already existing treatment device.
Eine vorstehend beschriebene Wasseraufbereitung mit anschließender Rückführung in den Tank kann dann selbsttätig durchgeführt werden, wenn eine Messeinrichtung, mit welcher die elektrische Leitfähigkeit des Wassers ermittelt wird, die Überschreitung eines Leitfähigkeits-Grenzwertes erkennt. Diese Messeinrichtung kann idealerweise im Tank selbst vorgesehen sein und es erfolgt die Auswertung der Signale eines oder mehrerer entsprechender Sensoren sowie der Vergleich mit einem Grenzwert vorzugsweise seitens der bereits genannten elektronischen Steuereinheit.A water treatment described above with subsequent return to the tank can then be carried out automatically when a measuring device with which the electrical conductivity of the water is detected, detects the exceeding of a conductivity limit. This measuring device may ideally be provided in the tank itself and there is the evaluation of the signals of one or more corresponding sensors and the comparison with a limit value preferably by the aforementioned electronic control unit.
Vorzugsweise wird eine vorstehend beschriebene selbsttätige Wasseraufbereitung (in der Aufbereitungsvorrichtung) mit anschließender Rückführung in den Wasser-Tank nur während des Betriebs des Kraftfahrzeugs oder wenn das Kraftfahrzeug mit einem elektrischen Stromnetz verbunden ist, um eine elektrische Speicherbatterie zu beladen, was im Rahmen der vorliegenden Erfindung auch als ein Betrieb des Kraftfahrzeugs zu verstehen ist. In solchen Fällen ist also gewährleistet, dass genügend Energie zum Betreiben der Fördervorrichtung für das Wasser und weiterer Verbraucher von elektrischer Energie, die für die Durchführung des Verfahrens aktiv sein müssen, zur Verfügung steht.Preferably, an above-described automatic water treatment (in the treatment device) with subsequent return to the water tank only during operation of the motor vehicle or when the motor vehicle is connected to a power grid to load an electric storage battery, which is within the scope of the present invention Also to be understood as an operation of the motor vehicle. In such cases, it is thus ensured that sufficient energy is available for operating the conveying device for the water and other consumers of electrical energy which must be active for carrying out the method.
Eine vorstehend beschriebene Wasseraufbereitung mit anschließender Rückführung in den Tank kann auch dann selbsttätig durchgeführt werden, wenn vorgegebene Betriebszeit-Intervalle des Kraftfahrzeugs abgelaufen sind, d.h. dass die Aufbereitung zeitorientiert nur zeitweise durchgeführt wird. Alternativ kann aber auch kontinuierlich dann, wenn das Kraftfahrzeug in Betrieb ist, eine geringe Menge von Wasser als sog. Grundumwälzmenge durch die Aufbereitungsvorrichtung und zurück in den Wassertank geführt werden. Ebenso kann die selbsttätige Wasseraufbereitung mit anschließender Rückführung des Wassers in den Tank anschließend an eine Neubefüllung des Wassertanks für eine vorgegebene Zeitdauer durchgeführt werden.An above-described water treatment with subsequent return to the tank can be carried out automatically even if predetermined operating time intervals of the motor vehicle have expired, i. that the preparation is time-based only temporarily carried out. Alternatively, however, even when the motor vehicle is in operation, a small amount of water can continuously be passed as a so-called. Grundumwälzmenge through the treatment device and back into the water tank. Likewise, the automatic water treatment can be carried out with subsequent return of the water in the tank following a refilling of the water tank for a predetermined period of time.
