Abstract
Description
Die Erfindung betrifft eine Kraftstoffversorgungseinrichtung für eine Brennkraftmaschine gemäß den Merkmalen des Oberbegriffs des Patentanspruchs 1.The The invention relates to a fuel supply device for an internal combustion engine according to the characteristics the preamble of claim 1.
Aus
der
Aufgabe der Erfindung ist es daher, eine Kraftstoff-Druckverstärkungseinrichtung zu schaffen, die einfach und kostengünstig umsetzbar und hinsichtlich ihrer Kapazität auch an unterschiedliche Kraftstoffversorgungssysteme anpassbar ist.task The invention is therefore a fuel pressure boosting device to create that simple and inexpensive to implement and in terms of their capacity also adaptable to different fuel supply systems is.
Die Aufgabe wird durch die im Anspruch 1 angegebenen Merkmale gelöst.The The object is achieved by the features specified in claim 1.
Die nach dem hydraulischen Widder-Prinzip funktionierende Kraftstoff-Druckverstärkungseinrichtung zeichnet sich durch einen einfachen Aufbau aus und ist darüber hinaus variabel einsetzbar, da die Druckstöße über das ansteuerbare Sperrventil beliebig lange generierbar sind.The Fuel pressure boosting device operating according to the hydraulic ram principle is characterized by a simple structure and is beyond Can be used variably, as the pressure surges can be activated via the check valve can be generated for any length of time.
In den Unteransprüchen sind weitere Maßnahmen zur vorteilhaften Ausgestaltung und Weiterbildung der Kraftstoffversorgungseinrichtung enthalten.In the subclaims are further measures on the advantageous embodiment and development of the fuel supply device contain.
Zur Erzeugung von Druckstößen in der zum Kraftstoffverteiler (Hochdruckrail) führenden Druckleitung wird das Sperrventil über eine Steuereinheit getaktet betrieben.to Generation of pressure surges in the this becomes the pressure line leading to the fuel distributor (high pressure rail) Check valve over a control unit operated clocked.
Das vorgeschlagene Prinzip der Kraftstoff- Druckerhöhung vor bzw. während des Motorstarts eignet sich insbesondere für den Einsatz bei der Benzin-Direkteinspritzung, bei der neben einer elektrisch betriebenen Kraftstoff-Vorförderpumpe eine mechanisch angetriebene Hochdruckpumpe vorgesehen ist. Solange die beispielsweise von der Nockenwelle angetriebene Hochdruckpumpe noch nicht den für eine optimale Verbrennung erforderlichen Betriebsdruck erreicht hat, kann der Kraftstoffverteiler (Hochdruckrail) über die erfindungsgemäße Druckverstärkungseinrichtung mit entsprechendem Druck versorgt werden.The proposed principle of fuel pressure increase before or during Engine starts are particularly suitable for use in gasoline direct injection, in addition to an electrically operated fuel feed pump a mechanically driven high pressure pump is provided. As long as the high-pressure pump, for example driven by the camshaft not yet for one optimal combustion has reached the required operating pressure, can the fuel rail (high pressure rail) via the pressure boosting device according to the invention be supplied with appropriate pressure.
Die Erfindung wird nachfolgend anhand der Zeichnung und der Beschreibung näher erläutert.The Invention is described below with reference to the drawing and the description explained in more detail.
Die einzige Figur zeigt die schematische Darstellung einer Kraftstoff-Versorgungseinrichtung.The only figure shows the schematic representation of a fuel supply device.
Die
Kraftstoffversorgungseinrichtung weist einen Kraftstoffverteiler,
im folgenden als Hochdruckrail
Die
Kraftstoffversorgungseinrichtung funktioniert auf folgende Art und
Weise:
Bei der Entriegelung der Fahrzeugtür oder beispielsweise beim
Einschalten der Zündung
wird die elektrische Vorförderpumpe
When the vehicle door is unlocked or, for example, when the ignition is switched on, the electric feed pump is activated
