Description
Die Erfindung betrifft ein Verfahren zum Bestimmen des effektiven Kompressibilitätsmoduls eines Einspritzsystems, insbesondere eines Common-Rail-Einspritzsystems gemäß Oberbegriff des Hauptanspruchs.The The invention relates to a method for determining the effective compressibility module an injection system, in particular a common rail injection system according to the generic term of the main claim.
Bekannte Common-Rail-Einspritzanlagen umfassen ein Volumenstromregelventil (VCV-Volume Control Valve), das die Menge des Kraftstoffs regelt, der einer Hochdruckpumpe zugeführt wird und von dieser in einen Druckspeicher (Common Rail) gepumpt wird. Injektoren mit Einspritzdüsen werden von dem Common Rail versorgt und spritzen, von einem Steuergerät gesteuert, Kraftstoff in den Brennraum einer Brennkraftmaschine.Known Common rail injection systems include a volume flow control valve (VCV-Volume Control Valve), which regulates the amount of fuel that fed to a high-pressure pump is pumped and from this in a pressure accumulator (common rail) becomes. Injectors with injectors are supplied and injected by the common rail, controlled by a control unit, Fuel in the combustion chamber of an internal combustion engine.
Bei dieser Art von Einspritzanlage wird vorzugsweise eine Mengen-basierte Druckregelung vorgenommen, wobei die grundlegende physikalische Beziehung für jede Art dieser Druckregelung die Gleichung dP/dt = E/V·Q ist. Dabei bezeichnet P den Druck im System, E den Kompressibilitätsmodul, V das Volumen des Druckspeichers und Q den an dem Druckspeicher bzw. das Rail gelieferten Volumenstrom. Um mittels eines bestimmten Volumenstroms Q einen definierten Druckgradienten dP/dt einstellen zu können, muss folglich die Proportionalitätskonstante E/V bekannt sein. Während das Volumen V in der Regel mit hoher Genauigkeit bekannt ist, trifft dies für den E-Modul oft nicht zu. Bisher wurden für den E-Modul Kennlinien verwendet, die aus der Literatur bekannt sind und die für unterschiedliche Kraftstoffe differenzieren. Zum einen existieren jedoch nicht immer für jeden verwendeten Kraftstoff Literaturwerte, zum anderen muss aber für eine genaue Druckregelung der "effektive" Kompressibilitätsmodul des Gesamtsystems, bestehend aus Medium, d. h. Kraftstoff und der umgebenden Wand verwendet werden. Dafür liegen jedoch keine Literaturwerte (Hochdruckpumpe, Rail, Leitungen, Injektoren) vor.at This type of injection system is preferably a quantity-based Pressure regulation made taking the basic physical relationship for every Type of pressure control is the equation dP / dt = E / V · Q. Where P denotes the pressure in the system, E the compressibility modulus, V is the volume of the pressure accumulator and Q is the pressure accumulator or the rail delivered volume flow. To use a specific Volume flow Q set a defined pressure gradient dP / dt can, must therefore have the proportionality constant E / V be known. While the volume V is usually known with high accuracy, this is true for the E-module often not to. So far, for the E-module uses characteristic curves that are known from the literature and the for Differentiate different fuels. For one thing exist but not always for each used fuel literature values, on the other hand but needs for one accurate pressure control the "effective" compressibility module of the whole system, consisting of medium, d. H. Fuel and the surrounding wall to be used. However, there are no literature values (high-pressure pump, Rail, lines, injectors) in front.

Dadurch, dass anhand der Beziehung zwischen dem Tastverhältnis des dem Volumenstromregelventil zugeführten Steuerstroms bzw. dem effektiven Strom und dem gelieferten Kraftstoffvolumenstrom des VCVs die Brennkraftmaschine in einen Zustand mit einem definierten Kraftstoffvolumenstrom gebracht wird, wobei die Beziehung zwischen dem Tastverhältnis des dem Volumenstromregelventil zugeführten Steuerstroms bzw. dem effektiven Strom und dem gelieferten Kraftstoffvolumenstrom des VCVs vorgegeben ist, danach das zugehörige bekannte Tastverhältnis des Steuerstroms eingestellt wird und der sich dann einstellende Druck des Hochdruckbereichs gemessen wird, dass das Tastverhältnis und somit der Kraftstoff-Volumenstrom anschließend geändert wird und die Druckänderung gemessen wird und dass aus der Gleichung dP/dt = E/V·ΔQ der Kompressibilitätsmodul bestimmt wird, kann der effektive Kompressionsmodul des Gesamtsystems, bestehend aus Kraftstoff und der umgebenden Wand, in einfacher Weise gefunden werden. Durch die Verwendung des erfindungsgemäß ermittelten Wertes des effektiven Kompressibilitätsmoduls kann die Leistungsfähigkeit der Druckregelung verbessert werden. Außerdem lässt sich der Vorgang der Kalibration des Raildruck-Reglers auf diese Weise vereinfachen und verkürzen.Thereby, that based on the relationship between the duty cycle of the flow control valve supplied Control flow or the effective flow and the supplied fuel flow of the VCV, the internal combustion engine in a state with a defined Fuel flow is brought, the relationship between the duty cycle of the flow control valve supplied control flow or the effective current and the delivered fuel volume flow of the VCV is given, then the associated known duty cycle of the control current is set and then adjusting Pressure of the high pressure area is measured, that is the duty cycle and thus the fuel flow rate is subsequently changed and the pressure change is measured and that from the equation dP / dt = E / V · ΔQ the compressibility modulus is determined, the effective compression modulus of the overall system, consisting from fuel and the surrounding wall, found in a simple way become. By using the inventively determined value of the effective Kompressibilitätsmoduls can the performance the pressure control can be improved.

In vorteilhafter Weise kann die vorgegebene Beziehung zwischen dem Tastverhältnis des Ansteuerstroms des Volumenstromregelventils und seinem gelieferten Kraftstoffvolumenstrom dadurch bestimmt werden, dass gemäß einem ersten Schritt die Brennkraftmaschine in einen stationären Zustand mit konstantem Verbrauch gebracht wird und in einem zweiten Schritt das Tastverhältnis des Ansteuerstroms des Volumenstromregelventils so justiert wird, dass sich ein konstanter Druck im Hochdruckbereich einstellt, wodurch ein erstes Wertepaar, Tastverhältnis bzw. Strom und Volumenstrom, erstellt wird und dass die ersten und zweiten Schritte solange wiederholt werden, bis eine ausreichend genaue Kennlinie geliefert wird.Advantageously, the predetermined relationship between the duty cycle of the drive current of the volume flow control valve and its delivered fuel flow can be determined that according to a first step, the internal combustion engine is brought into a steady state state with constant consumption and in a second step, the duty cycle of the drive current of the flow control valve so that is adjusted a constant pressure is established in the high pressure region, whereby a first pair of values, duty cycle and flow rate is created and that the first and second steps are repeated until a sufficiently accurate characteristic is provided.

In der Regel ist der E-Modul nicht nur abhängig vom Druck, sondern auch von der Temperatur. Zusätzlich ist daher ein Temperatursensor vorgesehen und das oben beschriebene Verfahren wird bei verschiedenen Drücken und Temperaturen wiederholt, wobei unterschiedliche stationäre Zustände des Motors eingestellt werden. Der E-Modul kann somit in einem Kennlinienfeld in Abhängigkeit von den Variablen Druck und Temperatur zusammengefasst und einem Steuergerät gespeichert werden.In As a rule, the modulus of elasticity not only depends on the pressure, but also from the temperature. additionally Therefore, a temperature sensor is provided and the above-described Process is repeated at different pressures and temperatures, being different stationary conditions of the motor. The modulus of elasticity can thus be in a characteristic field dependent on summarized by the variables pressure and temperature and one control unit get saved.
