Description
Die Erfindung betrifft ein Fahrzeug gemäß Oberbegriff des Anspruchs 1, außerdem ein Verfahren zum Abführen von Schadgas gemäß Oberbegriff des Anspruchs 7 sowie eine Verwendung einer Vakuumpumpe gemäß Anspruch 8.The The invention relates to a vehicle according to the preamble of the claim 1, as well a method for removal of noxious gas according to the preamble of Claim 7 and a use of a vacuum pump according to claim 8th.
Fahrzeuge, insbesondere Kraftfahrzeuge, der hier angesprochenen Art sind bekannt. Sie weisen eine Brennkraftmaschine auf, bei der mindestens eine Brennkammer an einen drucklosen Ölraum angrenzt. Bei Betrieb der Brennkammer entstehen Schadgase, die größtenteils über eine Filtervorrichtung bzw. einen Katalysator abgeführt werden. Aufgrund von Undichtigkeiten der Brennkammer gelangt ein geringer Teil der Schadgase in den drucklosen Ölraum, insbesondere Kurbelwellenraum (Kurbelgehäuse). Schadgase verursachen dort Korrosion und/oder können über Undichtigkeiten ungefiltert in die Umwelt entweichen. Aus diesem Grunde ist bei den bekannten Fahrzeugen eine Schadgasabführeinrichtung, insbesondere eine PCV-Einrichtung, vorgesehen. Die Schadgasabführeinrichtung weist eine Verbindung mit einer Luftzuführung auf, über die dem drucklosen Ölraum Luft zugeführt wird. Darüber hinaus weist die Schadgasabführeinrichtung eine Verbindung des drucklosen Ölraums mit einer an die Brennkammer angeschlossenen Luftversorgung der Brennkraftmaschine auf. Der drucklose Ölraum wird dadurch mit Luft gespült, welche die Schadgases mitnimmt und der Brennkammer zuleitet. Der Luftdurchsatz durch den drucklosen Ölraum wird vom Druckgefälle zwischen Luftzuführung und Luftversorgung bestimmt. Dieses Druckgefälle ist abhängig vom Betriebszustand der Brennkraftmaschine. Die Entsorgung der Schadgase ist in bestimmten Betriebszuständen gegebenenfalls nicht ausreichend.Vehicles, In particular motor vehicles, the type mentioned here are known. You have an internal combustion engine, at least one Combustion chamber to a non-pressurized oil chamber borders. When operating the combustion chamber, harmful gases are produced, most of them via a Filter device or a catalyst are discharged. Due to leaks the combustion chamber enters a small part of the noxious gases in the unpressurized oil chamber, in particular Crankshaft space (crankcase). Harmful gases cause corrosion and / or unfiltered leaks escape to the environment. For this reason, in the known Vehicles a Schadgasabführeinrichtung, in particular a PCV device provided. The Schadgasabführeinrichtung has a connection with an air supply via which the unpressurized oil space air supplied becomes. About that In addition, the Schadgasabführeinrichtung a connection of the unpressurized oil space with an air supply to the internal combustion engine connected to the combustion chamber on. The unpressurized oil room is thereby flushed with air, which entrains the harmful gases and the combustion chamber zuleitet. Of the Air flow through the unpressurized oil space is the pressure gradient between air supply and air supply. This pressure gradient depends on the operating condition of the Internal combustion engine. The disposal of noxious gases is certain operating conditions may not be sufficient.
Es ist daher Aufgabe der Erfindung, ein Fahrzeug zu schaffen, das eine Verbesserung der Entsorgung von in dem drucklosen Ölraum befindlichen Schadgasen gewährleistet.It It is therefore an object of the invention to provide a vehicle that has a Improvement of disposal of pollutants located in the non-pressurized oil space guaranteed.
Zur Lösung dieser Aufgabe wird ein Fahrzeug vorgeschlagen, welches die in Anspruch 1 genannten Merkmale umfasst, nämlich ein Fahrzeug, insbesondere Kraftfahrzeug, mit einer eine Schadgasabführeinrichtung, insbesondere einer PCV-Einrichtung (PCV = Positive Crankcase Ventilation = Positive Kurbelgehäuse-Entlüftung), aufweisenden Brennkraftmaschine und mit einem eine Vakuumpumpe aufweisenden Fahrzeugaggregat, insbesondere Bremskraftverstärker, wobei die Schadgasabführeinrichtung mit einer Luftzuführung verbunden ist und die Vakuumpumpe eine mit dem Fahrzeugaggregat verbun dene Saugseite und eine Druckseite aufweist. Das Fahrzeug zeichnet sich dadurch aus, dass die Druckseite der Vakuumpumpe mit der Schadgasabführeinrichtung und dass die Saugseite der Vakuumpumpe mit der Luftzuführung verbunden ist. Die im Fahrzeug ohnehin schon vorhandene Vakuumpumpe des Fahrzeugaggregats, insbesondere Bremskraftverstärkers, ist somit der Schadgasabführeinrichtung funktionell zugeordnet. Unabhängig vom Betriebszustand der Brennkraftmaschine evakuiert die Vakuumpumpe das Fahrzeugaggregat und gewährleistet die Funktion eines hinreichenden Durchsatzes von Luft durch den drucklosen Ölraum. Der drucklose Ölraum wird mittels der Vakuumpumpe also derart beaufschlagt, dass stets eine hinreichende Durchspülung unabhängig vom Betriebszustand der Brennkraftmaschine gegeben ist. Dadurch stellt sich nur eine geringe Konzentration an Schadgasen in allen Betriebszuständen der Brennkraftmaschine ein, so dass Korrosion und ein Entweichen der Schadgase an die Umwelt vermieden wird.to solution This object is a vehicle proposed which the claim 1 features, namely a vehicle, in particular a motor vehicle, with a harmful gas discharge device, in particular a PCV device (PCV = Positive Crankcase Ventilation = Positive crankcase ventilation), having an internal combustion engine and having a vacuum pump having a Vehicle unit, in particular brake booster, wherein the Schadgasabführeinrichtung with an air supply is connected and the vacuum pump with the vehicle unit verbun dene suction side and having a pressure side. The vehicle is characterized by the fact that the pressure side of the vacuum pump with the Schadgasabführeinrichtung and that the suction side of the vacuum pump is connected to the air supply is. The already existing in the vehicle vacuum pump of the vehicle unit, in particular brake booster, is thus the Schadgasabführeinrichtung functionally assigned. Independent of Operating state of the internal combustion engine evacuates the vacuum pump the vehicle aggregate and guaranteed the function of a sufficient flow of air through the unpressurized oil room. Of the pressureless oil room is thus applied by the vacuum pump so that always a sufficient flushing independently given by the operating condition of the internal combustion engine. Thereby presents only a low concentration of noxious gases in all operating conditions the internal combustion engine, allowing corrosion and escape the noxious gases to the environment is avoided.
Darüber hinaus ist es vorteilhaft, dass ein bereits vorhandenes Bauteil, nämlich die Vakuumpumpe, benutzt werden kann und die Kosten daher gering gehalten werden.Furthermore it is advantageous that an already existing component, namely the Vacuum pump, can be used and the costs therefore kept low become.
Weitere Vorteile ergeben sich aus den Merkmalen der Unteransprüche.Further Advantages result from the features of the subclaims.
Ferner betrifft die Erfindung ein Verfahren zum Abführen von Schadgas bei einem mit einer Brennkraftmaschine versehenen Fahrzeug mittels einer Schadgasabführeinrichtung, insbesondere PCV-Einrichtung. Das Verfahren ist dadurch gekennzeichnet, dass eine einem Evakuieren eines Fahrzeugaggregats, insbesondere eines Bremskraftverstärkers, dienende Vakuumpumpe auch zum insbesondere dosierten Zuführen von Spülluft für die Schadgasabführeinrichtung eingesetzt ist.Further The invention relates to a method for removing harmful gas in a equipped with an internal combustion engine vehicle by means of a Schadgasabführeinrichtung, especially PCV device. The method is characterized in that an evacuation of a vehicle aggregate, in particular a brake booster, Serving vacuum pump for the particular metered feeding of purge air for the Schadgasabführeinrichtung is used.
Ferner betrifft die Erfindung eine Verwendung einer Vakuumpumpe eines Fahrzeugaggregats, insbesondere Bremskraftverstärkers, zum insbesondere gleichzeitigen Zuführen von Spülluft zu einer Schadgasabführeinrichtung, insbesondere PCV-Einrichtung, einer Brennkraftmaschine eines Fahrzeugs. Besonders vorteilhaft bei dieser Verwendung ist es, dass die ohnehin schon vorhandene Vakuumpumpe des Fahrzeugaggregats, insbesondere Bremskraftverstärkers, auch dem Zuführen von Spülluft der Schadgasabführeinrichtung dient und dadurch eine Doppelverwendung vorliegt. Die Doppelverwendung der Vakuumpumpe erspart den Einbau einer zusätzlichen Pumpe und führt zu einer effizienteren Nutzung der bereits vorhandenen Vakuumpumpe.Further the invention relates to a use of a vacuum pump of a vehicle aggregate, in particular brake booster, for the particular simultaneous supply of purging air to a Schadgasabführeinrichtung, in particular PCV device, an internal combustion engine of a vehicle. Particularly advantageous in this use is that the anyway already existing vacuum pump of the vehicle unit, in particular brake booster, too the feeding of purge air the Schadgasabführeinrichtung serves and thereby a double use exists. The double use The vacuum pump saves the installation of an additional pump and leads to a more efficient use of the existing vacuum pump.
