Hierbei ist das Druckbegrenzungsventil (20) zusätzlich als Entlüftungs- und Entleerungsventil ausgebildet.The invention relates to a fuel supply device for an internal combustion engine, in particular a direct injection gasoline engine, in particular of a motor vehicle, with a high pressure line (10) for fuel, which is connected to a pressure relief valve (20). Here, the pressure relief valve (20) is additionally designed as a venting and drain valve.
Description
Die Erfindung betrifft eine Kraftstoffversorgungseinrichtung für eine Brennkraftmaschine, insbesondere einen direkteinspritzenden Ottomotor, insbesondere eines Kraftfahrzeugs, mit einer Hochdruckleitung für Kraftstoff, welche mit einem Druckbegrenzungsventil verbunden ist, gemäß dem Oberbegriff des Patentanspruchs 1. Die Erfindung betrifft ferner ein Verfahren zum Betreiben einer Brennkraftmaschine, insbesondere eines direkteinspritzenden Ottomotors, insbesondere eines Kraftfahrzeugs, mit einer Kraftstoffversorgungseinrichtung, die eine Hochdruckleitung für Kraftstoff, welche mit einem Druckbegrenzungsventil verbunden ist, aufweist, gemäß dem Oberbegriff des Patentanspruchs 10.The The invention relates to a fuel supply device for an internal combustion engine, in particular a direct injection gasoline engine, in particular a motor vehicle, with a high-pressure line for fuel, which is connected to a pressure relief valve, according to the preamble of patent claim 1. The invention further relates to a method for operating an internal combustion engine, in particular a direct injection gasoline engine, in particular of a motor vehicle, with a fuel supply device, the one high pressure line for Fuel, which is connected to a pressure relief valve, according to the preamble of claim 10.

Der Erfindung liegt die Aufgabe zugrunde, ein Kraftstoffsystem, insbesondere Hochdrucksystem, für eine Brennkraftmaschine, insbesondere eines direkteinspritzenden Ottomotors, zu verbessern.Of the Invention is based on the object, a fuel system, in particular High pressure system, for an internal combustion engine, in particular a direct injection Ottomotors, to improve.
Diese Aufgabe wird erfindungsgemäß durch eine Kraftstoffversorgungseinrichtung der o.g. Art mit den in Anspruch 1 gekennzeichneten Merkmalen und durch ein Verfahren der o.g. Art mit den in Anspruch 10 gekennzeichneten Merkmalen gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den abhängigen Ansprüchen angegeben.These The object is achieved by a Fuel supply device of the o.g. Kind of claim 1 characterized features and by a method of o.g. kind solved with the features characterized in claim 10. Advantageous embodiments of the invention are in the dependent claims specified.
Dazu ist es bei einer Kraftstoffversorgungseinrichtung der o.g. Art erfindungsgemäß vorgesehen, dass das Druckbegrenzungsventil zusätzlich als Entlüftungs- und Entleerungsventil ausgebildet ist.To it is the o.g. Art provided according to the invention, that the pressure relief valve additionally acts as a venting and drain valve is formed.
Ferner ist es bei einem Verfahren der o.g. Art erfindungsgemäß vorgesehen, dass die Hochdruckleitung über das Druckbegrenzungsventil entlüftet und entleert wird.Further is it in a procedure of o.g. Art provided according to the invention, that the high pressure line over the pressure relief valve vented and is emptied.
Dies hat den Vorteil, dass das Druckbegrenzungsventil gleichzeitig als Entlüftungs- und Entleerungsventil für die Kraftstoffversorgungseinrichtung dient, so dass eine Dauer für das Befüllen der Kraftstoffversorgungseinrichtung mit Kraftstoff bzw. für das Entleeren von Kraftstoff aus der Kraftstoffversorgungseinrichtung wesentlich reduziert ist.This has the advantage that the pressure relief valve at the same time vent and drain valve for the fuel supply device is used, so that a duration for filling the Fuel supply device with fuel or for emptying of fuel from the fuel supply essential is reduced.
Beispielsweise ist die Hochdruckleitung als Kraftstoffverteilerleiste ausgebildet.For example the high pressure line is designed as a fuel rail.
Zweckmäßigerweise ist das Druckbegrenzungsventil in einer rohrförmigen Zweigleitung der Hochdruckleitung für Kraftstoff angeordnet, wobei die Zweigleitung eine Rücklauföffnung aufweist. Die Zweigleitung ist an einem von der Hochdruckleitung abgewandten Ende offen, wobei das Druckbegrenzungsventil in diese offene Seite sowie diese verschließend eingeschoben ist.Conveniently, is the pressure relief valve in a tubular branch line of the high pressure line for fuel arranged, wherein the branch line has a return opening. The branch line is open at one end facing away from the high pressure line, wherein the pressure relief valve inserted into this open side and this closing is.
In einer bevorzugten Ausführungsform ist das Druckbegrenzungsventil in der Zweigleitung in eine erste Position und eine zweite Position axial verschiebbar, wobei in der ersten Position das Druckbegrenzungsventil die Rücklauföffnung von der Hochdruckleitung trennt und in der zweiten Position die Rücklauföffnung in fluidleitender Verbindung mit der Hochdruckleitung steht. Hierbei ist das Druckbegrenzungsventil in der ersten Position lösbar festgelegt, so dass es beispielsweise manuell einfach lösbar und verschließbar ist.In a preferred embodiment is the pressure relief valve in the branch line in a first Position and a second position axially displaceable, wherein in the first position the pressure relief valve the return port of the high pressure line separates and in the second position, the return opening in fluid-conducting connection with the high pressure line is. Here is the pressure relief valve solvable in the first position set, so that it is manually easily solvable and closed, for example.
In einer alternativen bevorzugten Ausführungsform weist das Druckbegrenzungsventil einen Kanal auf, welcher die Hochdruckleitung mit der Rücklauföffnung verbindet, wobei in dem Druckbegrenzungsventil ein Schließelement vorgesehen ist, welches in eine den Kanal verschließende Schließposition und eine den Kanal öffnende Position verschiebbar ist. Das Schließelement ist zweckmäßigerweise in Richtung der Schließposition mit einer elastischen Kraft beaufschlagt, wobei bevorzugt ein Federelement vorgesehen ist, welches das Schließelement in die Schließposition drückt.In an alternative preferred embodiment, the pressure relief valve a channel connecting the high pressure line to the return port, wherein in the pressure limiting valve, a closing element is provided, which in a closing the channel closed position and one opening the channel Position is displaced. The closing element is expediently in the direction of the closed position acted upon by an elastic force, wherein preferably a spring element is provided, which the closing element in the closed position suppressed.
