Aufgabe der Erfindung ist es, ein Verfahren der eingangs genannten Art, wie auch ein Steuergerät und eine Kraftstoffzuführeinrichtung der jeweils eingangs genannten Art derart weiterzubilden, dass eine möglichst genaue Zumessung der erwünschten Kraftstoffmenge in die Brennräume der Brennkraftmaschine möglich ist.The object of the invention is a Method of the type mentioned, as well as a control unit and fuel supply of the type mentioned at the outset in such a way that a preferably accurate metering of the desired amount of fuel into the combustion chambers the internal combustion engine possible is.
Diese Aufgabe wird bei einem Verfahren der eingangs genannten Art durch die kennzeichenden Merkmale des Anspruchs 1 gelöst. Bei einem Steuergerät oder einer Kraftstoffzuführeinrichtung der eingangs genannten Art wird die Aufgabe durch die kennzeichenden Merkmale der nebengeordneten Ansprüche 10 und 11 gelöst.This task is done in a process of the type mentioned by the characterizing features of Claim 1 solved. With a control unit or a fuel supply device of the type mentioned above, the task is characterized by Features of the independent claims 10 and 11 solved.
Der Schließzeitpunkt des Mengensteuerventils stellt im Wesentlichen denjenigen Zeitpunkt dar, ab dem Kraftstoff von der Hochdruckpumpe zu den Einspritzdüsen und damit zu den Brennräumen der Brennkraftmaschine gefördert wird. Durch den Schließzeitpunkt des Mengensteuerventils wird auch die den Brennräumen und damit der Brennkraftmaschine zugeführte Kraftstoffmenge beeinflusst. Der Schließzeitpunkt des Mengensteuerventils selbst ist von einer Mehrzahl von Größen abhängig. So wird der Schließzeitpunkt eher erreicht, wenn die Batteriespannung, an der das Mengensteuerventil anliegt, groß ist. Ebenfalls bestehen Abhängigkeiten des Schließzeitpunkts von dem Spulenwiderstand des Mengensteuerventils, da dieser den Strom durch das Mengensteuerventil bestimmt. Erfindungsgemäß werden diese Abhängigkeiten bei der Ansteuerung des Mengensteuerventils berücksichtigt. So wird bei der Erfindung die Abhängigkeit des Mengensteuerventils von der Batteriespannung und/oder von dem Spulenwiderstand bei der Ermittlung und daraus resultierenden Ansteuerung des Mengensteuerventils zugrunde gelegt. Dadurch wird der Vorteil erreicht, dass die über das Mengensteuerventil beeinflusste, der Brennkraftmaschine zugeführte Kraftstoffmenge auch bei unterschiedlichen Batteriespannungen und/oder bei unterschiedlichen Spulenwiderständen immer dem erwünschten Wert entspricht. Die Genauigkeit der Kraftstoffzumessung wird damit verbessert, was gleichbedeutend ist mit einer Verminderung des Kraftstoffverbrauchs, wie auch mit einer Verminderung von ausgestoßenen Schadstoffen.The closing time of the volume control valve essentially represents the point in time from which fuel from the high pressure pump to the injection nozzles and thus to the combustion chambers of the internal combustion engine promoted becomes. By the closing time The quantity control valve also becomes the combustion chambers and thus the internal combustion engine supplied Fuel quantity affected. The closing time of the volume control valve itself depends on a variety of sizes. So is the closing time rather reached when the battery voltage at which the volume control valve is big. There are also dependencies the closing time of the coil resistance of the volume control valve, since this the Current determined by the volume control valve. According to the invention these dependencies taken into account when controlling the volume control valve. So at Invention the dependency the quantity control valve from the battery voltage and / or from the coil resistance in determining and resulting control of the volume control valve placed. This has the advantage that the over Quantity control valve also influenced the amount of fuel supplied to the internal combustion engine at different battery voltages and / or at different Coil resistances always the desired one Value corresponds. This increases the accuracy of the fuel metering improved, which is equivalent to a reduction in fuel consumption, as well as a reduction in pollutants emitted.
Bei einer vorteilhaften Weiterbildung der Erfindung wird der Spulenwiderstand aus einer Spulentemperatur des Mengensteuerventils ermittelt. Es ist damit erfindungsgemäß nicht erforderlich, den Spulenwiderstand direkt zu messen. Stattdessen reicht es aus, die Spulentemperatur zu erfassen. Aus dieser Spulentemperatur kann auf den Spulenwiderstand geschlossen werden. Die Spulentemperatur des Mengesteuerventils wiederum kann in besonders vorteilhafter Weise aus der Kühlwassertemperatur der Brennkraftmaschine und/oder aus der Ansauglufttemperatur der Brennkraftmaschine ermittelt werden.With an advantageous further education the invention, the coil resistance from a coil temperature of the volume control valve determined. It is therefore not according to the invention required to measure the coil resistance directly. Instead it is sufficient to record the coil temperature. From this coil temperature can be deduced from the coil resistance. The coil temperature of the Flow control valve in turn can be particularly advantageous from the cooling water temperature the internal combustion engine and / or from the intake air temperature Internal combustion engine can be determined.
Bei einer vorteilhaften Ausgestaltung der Erfindung wird das Mengensteuerventil in Abhängigkeit von dem von der Hochdruckpumpe erzeugten Ist-Druck beeinflusst. Auf diese Weise wird durch die Erfindung berücksichtigt, dass das Schließen des Mengensteuerventils und damit der Schließzeitpunkt des Mengensteuerventils abhängig ist von dem von der Hochdruckpumpe erzeugten Ist-Druck. Dieser Ist-Druck wirkt auf das Mengensteuerventil in dem Sinne ein, dass er den Schließvorgang des Mengensteuerventils unterstützt. Durch die Berücksichtigung dieses Ist-Drucks wird die Genauigkeit der Kraftstoffzumessung mit den bereits erläuterten Vorteilen weiter verbessert.In an advantageous embodiment of the invention, the quantity control valve is dependent on that of the high pressure pump generated actual pressure influenced. In this way, the invention considered, that closing of the volume control valve and thus the closing time of the volume control valve dependent is from the actual pressure generated by the high pressure pump. This actual pressure affects that Volume control valve in the sense that it is the closing process of the volume control valve supported. By considering this Actual pressure, the accuracy of the fuel metering with the already explained Benefits further improved.
Bei einer weiteren vorteilhaften Ausgestaltung der Erfindung wird das Mengensteuerventil in Abhängigkeit von der Drehzahl der Brennkraftmaschine beeinflusst. Insbesondere bei Verwendung einer mechanischen Hochdruckpumpe, die mit der Brennkraftmaschine gekoppelt ist, hat die Drehzahl der Brennkraftmaschine einen direkten Einfluss auf die Hochdruckpumpe. Dies wird erfindungsgemäß dadurch berücksichtigt, dass die Drehzahl der Brennkraftmaschine bzw. der Hochdruckpumpe in die Ansteuerung des Mengensteuerventils eingeht. Auch durch diese Maßnahme wird die Genauigkeit der Zumessung von Kraftstoff zu den Brennräumen der Brennkraftmaschine weiter verbessert.In a further advantageous embodiment of the invention, the quantity control valve is influenced as a function of the speed of the internal combustion engine. In particular when using a mechanical high-pressure pump which is coupled to the internal combustion engine, the speed of the internal combustion engine has a direct influence on the high-pressure pump. This is according to the invention thereby takes into account that the speed of the internal combustion engine or the high-pressure pump is included in the control of the quantity control valve. This measure also improves the accuracy of the metering of fuel to the combustion chambers of the internal combustion engine.

Dabei ist auf dem Steuerelement ein. Programm abgespeichert, das auf einem Rechengerät, insbesondere auf einem Mikroprozessor, ablauffähig und zur Ausführung des erfindungsgemäßen Verfahrens geeignet ist.
