Description

Die Erfindung betrifft ein Kraftfahrzeug mit einem Kraftstofftank mit einem Speicherbehälter, insbesondere einem Aktivkohlefilter, für im Tank verflüchtigte Kraftstoffbestandteile, sowie mit einem von Fahrzeug-Antriebsaggregat unabhängigen Heizgerät für den Fahrzeug-Innenraum.The The invention relates to a motor vehicle with a fuel tank with a storage container, in particular an activated carbon filter, volatilized in the tank Fuel components, as well as with one of vehicle drive unit independent Heater for the vehicle interior.

Im Kraftstofftank eines Kraftfahrzeugs, dessen Antriebsaggregat in Form einer Brennkraftmaschine insbesondere mit Benzin betrieben wird, können sich bekanntlich Kraftstoffdämpfe bilden, die bevorzugt über einen sog. Aktivkohlefilter aufgefangen bzw. in diesem oder allgemein in einem Speicherbehälter zwischengespeichert werden. Dieser Aktivkohlefilter bzw. Speicherbehälter muss regelmäßig zur Regeneration bzw. Entleerung mit Luft gespült werden. Im normalen Betrieb werden die bei der Regeneration bzw. Spülung des Filters bzw. Speicherbehälters anfallenden Kraftstoffdämpfe im Fzg.-Antriebsaggregat verbrannt, indem dieses einen Teil seiner Ansaugluft über den Aktivkohlefilter ansaugt. Die Dosierung dieser Spülluft erfolgt dabei über ein sog. Tankentlüftungsventil, das von der elektronischen Steuereinheit des Antriebsaggregats geeignet angesteuert wird. Aus der DE 199 44 388 A1 ist es ferner bekannt, dass mit den verflüchtigten und im Aktivkohlefilter zwischengespeicherten Kraftstoffbestandteilen durch Verbrennung unter Verwendung der Spülluft ein Abgas-Katalysator der Fzg.-Brennkraftmaschine beheizt und somit auf seine Betriebstemperatur gebracht werden kann.In the fuel tank of a motor vehicle whose drive unit is operated in the form of an internal combustion engine, in particular with gasoline, known fuel vapors can form, which are preferably collected via a so-called. Activated carbon filter or cached in this or generally in a storage container. This activated carbon filter or storage tank must be regularly flushed with air for regeneration or emptying. During normal operation, the fuel vapors accumulating in the regeneration or rinsing of the filter or storage tank are burnt in the vehicle drive unit by sucking in part of its intake air via the activated carbon filter. The metering of this purge air takes place via a so-called. Tank vent valve, which is suitably controlled by the electronic control unit of the drive unit. From the DE 199 44 388 A1 It is also known that with the volatilized and cached in the activated carbon filter fuel components by combustion using the scavenging air, an exhaust gas catalyst of Fzg. internal combustion engine heated and thus can be brought to its operating temperature.

Bei einem Kraftfahrzeug mit einer Brennkraftmaschine als Antriebsaggregat, die wahlweise mit Benzin und alternativ mit Wasserstoff betrieben werden kann, und das dementsprechend mit zwei Kraftstoffversorgungsanlagen, nämlich für Benzin einerseits und Wasserstoff andererseits, versehen ist, ist während der Betriebsphase mit Wasserstoff eine Verwertung der anfallenden Benzindämpfe durch die Brennkraftmaschine naturgemäß nicht möglich.at a motor vehicle with an internal combustion engine as a drive unit, which are optionally operated with gasoline and alternatively with hydrogen can, and accordingly with two fuel supply systems, namely for gasoline on the one hand, and hydrogen, on the other hand, is provided during the Operating phase with hydrogen, a utilization of the resulting gasoline vapors by the internal combustion engine is not natural possible.

Hiermit soll nun aufgezeigt werden, wie in einem Speicherbehälter oder dgl. aufgefangene Kraftstoffbestandteile alternativ zu einer Verbrennung im Antriebsaggregat eines Kraftfahrzeugs nach dem Oberbegriff des Anspruchs 1 günstig verwertet werden können (= Aufgabe der vorliegenden Erfindung). Die Lösung dieser Aufgabe ist dadurch gekennzeichnet, dass ein bzw. das vom Fahrzeug-Antriebsaggregat unabhängiges) Heizgerät des Kraftfahrzeugs zumindest teilweise mit den im Speicherbehälter befindlichen Kraftstoffbestandteilen betrieben wird. Vorteilhafte Weiterbildungen sind Inhalt der Unteransprüche.Herewith will now be shown how in a storage tank or Like. Trapped fuel components as an alternative to combustion in the drive unit of a motor vehicle according to the preamble of Claim 1 low can be recycled (= Object of the present invention). The solution to this problem is thereby in that one or the vehicle drive unit independent) heater of the motor vehicle at least partially with those in the storage container Fuel components is operated. Advantageous developments are content of the subclaims.

Heizgeräte für den Fahrzeug-Innenraum, die Wärme unabhängig vom Fzg.-Antriebsaggregat entwickeln, sind grundsätzlich bekannt und werden oft als fahrzeugunabhängige Heizgeräte oder Brennstoff-Heizgeräte bezeichnet. Hiermit wird nun vorgeschlagen, ein solches Heizgerät zu verwenden, um die Spülluft des Aktivkohlefilters bzw. allg. des genannten Speicherbehälters sinnvoll zu verwerten.Heaters for the vehicle interior, the heat independently from the vehicle drive unit develop are basically are known and often called vehicle-independent heaters or Fuel heaters designated. It is now proposed to use such a heater, around the scavenging air the activated carbon filter or general of said storage container makes sense to recycle.

An dieser Stelle sei ausdrücklich darauf hingewiesen, dass die vorliegende Erfindung keineswegs auf Kraftfahrzeuge mit Brennkraftmaschinen beschränkt ist, die wahlweise mit Benzin oder Wasserstoff betrieben werden können, wenngleich dies in Verbindung mit der Aufgabe der vorliegenden Erfindung erwähnt ist. Unabhängig von dieser Aufgabe ist die vorliegende Erfindung auf jegliche Kraftfahrzeuge mit einer Brennkraftmaschine als Antriebsaggregat ohne weiteres übertragbar, wenngleich bei Kraftfahrzeu gen, die wahlweise auch mit Wasserstoff betrieben werden können, die vorliegende Erfindung sehr vorteilhaft einsetzbar ist, u.a. auch deshalb, weil solche Kraftfahrzeuge aufgrund des relativ geringen Wärmeeintrages ins Kühlwasser der Brennkraftmaschine während des Betriebsmodus mit Wasserstoff nur eine geringe Heizleistung für den Fahrgastraum aufweisen und daher zumeist mit einem eigenständigen Brennstoff-Heizgerät ausgestattet werden dürften.At this place is explicit noted that the present invention by no means Motor vehicles is limited to internal combustion engines, with optional Gasoline or hydrogen can be operated, albeit in conjunction mentioned with the object of the present invention. Independent of This object is the present invention to any motor vehicles with an internal combustion engine as a drive unit readily transferable, although in Kraftfahrzeu gene, which optionally also with hydrogen can be operated the present invention can be used very advantageously, i.a. also because such motor vehicles due to the relatively low heat input into the cooling water the internal combustion engine during operating mode with hydrogen only a low heat output for the Have passenger compartment and therefore usually equipped with a stand-alone fuel heater be allowed.

Für den Betrieb des Brennstoff-Heizgeräts sind unterschiedliche Betriebsmodi bzw. Konzepte möglich.For the business of the fuel heater different operating modes or concepts possible.

So kann dieses vom Fzg.-Antriebsaggregat unabhängige Brennstoff-Heizgerät praktisch wie üblich betrieben werden, wobei eine Zufuhr der sog. Spülluft des Aktivkohlefilters (bzw. Speicherbehälters) in einem solchen Mengenverhältnis zwischen weiterhin zugeführter sog. Brennluft und Spülluft erfolgt, dass für alle auftretenden Kraftstoff-Konzentrationen in der Spülluft des Aktivkohlefilters ein stabiler Brennbetrieb des Heizgeräts gewährleistet ist, ohne dass von dessen elektronischer Steuerung eine Korrektur gegenüber dem Normalbetrieb vorgenommen werden muss. Das für diese Betriebsweise zulässige Mengenverhältnis von Brennluft zu Spülluft kann dabei über eine geeignete Abstimmung der Strömungswiderstände im Luftansaugtrakt des Heizgeräts sowie im sog. Spülluftpfad, über den die mit den zunächst zwischengespeicherten Kraftstoffbestandteilen versehene Spülluft dem Heizgerät zugeführt wird, sichergestellt werden.So This fuel heater, which is independent of the vehicle's propulsion unit, can be practically used as usual operated, wherein a supply of the so-called. Purge air of the activated carbon filter (or storage container) in such a proportion between further supplied so-called combustion air and purge air done that for all occurring fuel concentrations in the purge air of the Activated carbon filter ensures a stable combustion operation of the heater is without any correction from its electronic control across from Normal operation must be made. The allowable for this mode of operation of Combustion air to purge air can over it a suitable coordination of the flow resistance in the air intake tract of the heater and in the so-called. Spülluftpfad, on the those with the first Cached fuel components provided scavenging the heater supplied will be ensured.

Abweichend hiervon kann die Kraftstoff-Konzentration in der Spülluft des Aktivkohlefilters oder dgl. bevorzugt über einen geeigneten Sensor erfasst und als Signalinformation dem Steuergerät des Brennstoff-Heizgeräts zur Verfügung gestellt werden. In diesem Steuergerät kann dann mit dieser Information eine Korrektur der von der Kraftstoffpumpe des Heizgerätes zu fördernden Brennstoffmenge ermittelt und die Ansteuerung der Kraftstoff pumpe entsprechend angepasst werden, um einen stabilen Brennbetrieb des Heizgeräts zu gewährleisten. Hierbei wird somit gesteuert bzw. geregelt das Heizgerät so betrieben, dass dieses die übliche Menge von Kraftstoff erhält, wobei die aus dem Kraftstofftank geförderte Brennstoffmenge entsprechend der über die Aktivkohlefilter-Spülluft zugeführten Kraftstoffmenge reduziert wird. Dabei ist es auch möglich, als weitere Größe die dem Brennstoff-Heizgerät über den sog. Spülluftpfad zugeführte Luftmenge zu erfassen und als weitere Korrekturinformation dem Steuergerät der Brennstoffheizung zur Verfügung zu stellen. Grundsätzlich kann dabei zur Förderung des Spülluftstromes durch den Aktivkohlefilter oder dgl. eine eigenständige, geeignet angesteuerte Luftpumpe vorgesehen sein.Deviating from this, the fuel concentration in the purge air of the activated carbon filter or the like. Preferably via a suitable sensor detected and as signal information to the control unit of Fuel heater are provided. In this control unit can then be determined with this information, a correction of the fuel pump of the heater to be pumped amount of fuel and the control of the fuel pump to be adjusted accordingly to ensure a stable combustion operation of the heater. In this case, the heating device is thus operated or regulated so that it receives the usual amount of fuel, wherein the amount of fuel delivered from the fuel tank is reduced in accordance with the amount of fuel supplied via the activated carbon filter purge air. In this case, it is also possible to detect the amount of air supplied to the fuel heater via the so-called purging air path as a further variable and to make it available to the control unit of the fuel heater as further correction information. In principle, an independent, suitably controlled air pump can be provided to promote the scavenging air flow through the activated carbon filter or the like.

Es ist aber auch möglich, dass das mit Kraftstoff betriebene Heizgerät die für die Brennstoff- oder Kraftstoffverbrennung benötigte sog. Brennluft vollständig über den sog. Spülluftpfad erhält. Auch hierbei kann die Kraftstoff-Konzentration in der Spülluft sowie die Brennluftmenge über geeignete Sensoren erfasst und als Signalinformation dem Steuergerät des Brennstoff-Heizgeräts zur Verfügung gestellt werden. Im Steuergerät wird mit dieser Information die von der Kraftstoffpumpe des Heizgerätes zu fördernde Brennstoffmenge ermittelt und die Ansteuerung der Kraftstoffpumpe geeignet angepasst, um einen stabilen Brennbetrieb des Heizgeräts zu gewährleisten.It but it is also possible that the fuel-fired heater is the one for fuel or fuel combustion needed so-called combustion air completely over the so-called purge air path receives. Again, the fuel concentration in the scavenging air as well the amount of combustion air over detected suitable sensors and provided as signal information to the control unit of the fuel heater. In the control unit This is the information to be conveyed by the fuel pump of the heater Fuel quantity determined and the control of the fuel pump adapted to ensure a stable burning operation of the heater.

Mit der vorgeschlagenen Maßnahme ist somit stets eine effiziente Spülung bzw. Regeneration des Aktivkohlefilters oder dgl. gewährleistet, wobei durchaus eine Vielzahl von Details abweichend von obigen Erläuterungen gestaltet sein können, ohne den Inhalt der Patentansprüche zu verlassen.With the proposed action is thus always an efficient conditioner or regeneration of the Activated carbon filter or the like. Ensures where quite a lot of details deviate from the above explanations can be designed without the content of the claims to leave.
