Abstract
Description
Stand der TechnikState of the art
Die Erfindung geht aus von einer Vorrichtung zur Kraftstoffversorgung einer Brennkraftmaschine, insbesondere in einem Kraftfahrzeug, nach dem Oberbegriff des Anspruchs 1.The The invention is based on a device for supplying fuel an internal combustion engine, in particular in a motor vehicle, according to the preamble of claim 1.
Eine
bekannte Kraftstoffversorgungseinrichtung für Kraftfahrzeuge
(
Offenbarung der ErfindungDisclosure of the invention
Die erfindungsgemäße Kraftstoffversorgungsvorrichtung mit den Merkmalen des Anspruchs 1 hat den Vorteil, dass die mindestens eine Saugstrahlpumpe nur dann eingeschaltet wird, wenn dies aufgrund des Füllstands im Vorratsbehälter zum Befüllen des Staubehälters oder Schwalltopfs erforderlich ist. Im Gegensatz zu den dauerhaft betriebenen Saugstrahlpumpen in den bekannten Kraftstoffversorgungseinrichtungen reduziert sich die Antriebsleistung für die mindestens eine Saugstrahlpumpe, d. h. die von der Förderpumpe über die Saugstrahlpumpe gepumte Kraftstofftreibmenge, deutlich, was zu einer reduzierten Bauteilbelastung und geringerem Kraftstoffverbrauch beiträgt. Durch die wesentliche Reduzierung der Einschaltdauer der mindestens einen Saugstrahlpumpe wird auch die durch das Umpumpen entstehende Ausgasungsrate des Kraftstoffs gesenkt, was wiederum zu einer Verringerung der Umweltbelastung beiträgt. Die Punktinformation zur Einschaltung der mindestens einen Saugstrahlpumpe wird mittels des vom Sensor detektierten Minimums des Füllstands im Vorratsbehälter gewonnen, bei dem eine Befüllung des Staubehälters notwendig wird.The Fuel supply device according to the invention with the features of claim 1 has the advantage that the at least a suction jet pump is only turned on, if this is due to the level in the reservoir for filling the dust container or swirl pot is required. in the Contrary to the permanently operated suction jet pumps in the known Fuel supply devices reduces the drive power for the at least one suction jet pump, d. H. the of the pump pumped via the suction jet pump Fuel flow rate, significantly, resulting in reduced component load and contributes to lower fuel consumption. By the essential Reduction of the duty cycle of the at least one suction jet pump is also the resulting by pumping outgassing of the Fuel is lowered, which in turn leads to a reduction in environmental impact contributes. The point information for engaging the at least a suction jet pump is detected by means of the minimum detected by the sensor the level in the reservoir won at a filling of the storage container necessary becomes.
Durch die in den weiteren Ansprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen der im Anspruch 1 angegebenen Kraftstoffversorgungsvorrichtung möglich.By the measures listed in the further claims are advantageous developments and improvements in the claim 1 specified fuel supply device possible.
Gemäß einer vorteilhaften Ausführungsform der Erfindung weist der Vorratsbehälter mindestens zwei durch einen Steg voneinander getrennte Kammern die sog. Haupt- und Transferkammer, auf. Beide Kammern stehen oberhalb des Stegs miteinander in Verbindung, wobei in jeder Kammer eine Saugstrahlpumpe und in der Hauptkammer der Staubehälter angeordnet ist. Bei dieser Ausbildung des Vorratsbehälters für den Kraftstoff kann ein einziger Sensor im Staubehälter oder alternativ in der Hauptkammer ein erster Sensor und in der Transferkammer ein zweiter Sensor angeordnet sein. Im ersten Fall setzt die Steuerelektronik auf das Ausgangssignal des einzigen Sensors hin alle Saugstrahlpumpen in Tätigkeit, während im zweiten Fall die Steuerelektronik mit dem Ausgangssignal des ersten Sensors beide Saugstrahlpumpen in Tätigkeit setzt und mit dem Ausgangssignal des zweiten Sensors die in der Transferkammer angeordnete Saugstrahlpumpe in ihren inaktiven Zustand zurücksetzt, so dass die Saugstrahlpumpe nach Leeren der Tankkammer bis zum Niveau des zweiten Sensors, der vorzugsweise am Boden der Transferkammer angeordnet ist, abgeschaltet ist.According to one advantageous embodiment of the invention, the reservoir at least two chambers separated by a bridge the so-called main and transfer chamber, on. Both chambers are above the web in conjunction, wherein in each chamber a suction jet pump and in the main chamber of the storage container is arranged. In this embodiment of the reservoir for The fuel can be a single sensor in the storage container or alternatively in the main chamber a first sensor and in the Transfer chamber to be arranged a second sensor. In the first case the control electronics sets to the output signal of the single sensor all the suction jet pumps in action while in the second case, the control electronics with the output signal of first sensor puts both suction jet pumps into action and with the output of the second sensor in the transfer chamber resets the arranged suction jet pump into its inactive state, so that the suction jet pump after emptying the tank chamber to the level of the second sensor, preferably at the bottom of the transfer chamber is arranged, is switched off.
Zur Aktivierung der mindestens einen Saugstrahlpumpe wird vorzugsweise ein elektromagnetisches Schaltventil herangezogen, das eine Treibmengenleitung der mindestens einen Saugstrahlpumpe an den Pumpenausgang der Förder pumpe anschließt. Das z. B. als 2/2-Magnetventil ausgebildete Schaltventil trennt die Verbindung zwischen dem Pumpenausgang der Förderpumpe und der Treibmengenleitung der Saugstrahlpumpe und stellt diese durch ein Steuersignal der Steuerelektronik her.to Activation of the at least one suction jet pump is preferably an electromagnetic switching valve used, which is a motive power line the at least one suction jet pump connected to the pump outlet of the delivery pump. The Z. B. as a 2/2-way solenoid valve formed separating valve the connection between the pump outlet of the feed pump and the flow line of the suction jet pump and provides this by a control signal of the control electronics ago.
Alternativ kann anstelle eines Schaltventils auch eine leistungskleine Elektrokraftstoffpumpe eingesetzt werden, die im Vorratsbehälter angeordnet ist und deren Pumpenausgang an die Treibmengenleitung der mindestens einen Saugstrahlpumpe angeschlossen ist. Bei Vorhandensein mehrerer Saugstrahlpumpen in mehreren Kammern des Vorratsbehälters ist jeder Saugstrahlpumpe eine eigene kleine Elektrokraftstoffpumpe zugeordnet die von der Steuerelektronik auf ein Ausgangssignal des mindestens einen Sensors hin gemeinsam eingeschaltet werden und ggf. auf ein Ausgangssignal eines weiteren Sensors hin getrennt wieder abgeschaltet werden.alternative may instead of a switching valve and a small power electric fuel pump can be used, which is arranged in the reservoir and their pump output to the mass flow of at least a suction jet pump is connected. In the presence of several suction jet pumps in several chambers of the reservoir is each suction jet pump its own small electric fuel pump assigned by the control electronics common to an output signal of the at least one sensor be turned on and possibly on an output signal of another Disconnected sensors are switched off again.
