Description
Die Neuerung betrifft eine Durchlüftungsanordnung nach dem Oberbegriff des Anspruchs 1.The Innovation concerns a ventilation arrangement according to the preamble of claim 1.
Eine gattungsgemäße Durchlüftungsanordnung ist aus der Motorentechnischen Zeitung MTZ, Ausgabe 10/2004, Jahrgang 65, Seite 5 aus der Übersicht „Systemaufbau aktueller Entlüftungssysteme" bekannt. Dabei schließt die Belüftungsleitung stromaufwärts vom Lader an den Luftansaugtrakt an. Unter einem „Lader" wird im Rahmen des vorliegenden Vorschlages ein Verdichter verstanden, der beispielsweise als abgasgetriebener Turbolader oder als mechanisch angetriebener Kompressor oder dergleichen ausgestaltet sein kann.A generic ventilation arrangement is from the engine technical newspaper MTZ, issue 10/2004, vintage 65, page 5 from the overview "System structure current venting systems. "In this case, the vent line closes upstream of Charger to the air intake. Under a "loader" is under the present proposal a compressor understood, for example, as an exhaust gas driven Turbocharger or as a mechanically driven compressor or the like can be designed.

Der Neuerung liegt die Aufgabe zugrunde, eine gattungsgemäße Durchlüftungsanordnung dahingehend zu verbessern, dass diese sowohl im Teillastbereich als auch im Volllastbereich der Brennkraftmaschine eine möglichst wirksame Durchlüftung des Kurbelgehäuses sicherstellt.Of the Innovation is the object of a generic ventilation arrangement be improved so that this both in the partial load range as well as possible in the full load range of the internal combustion engine effective ventilation of the crankcase ensures.
Diese Aufgabe wird durch eine Durchlüftungsanordnung mit den Merkmalen des Anspruchs 1 gelöst.These Task is through a ventilation arrangement solved with the features of claim 1.
Die Neuerung schlägt mit anderen Worten vor, die Belüftungsleitung in Luftströmungsrichtung hinter dem Lader anzuschließen und demzufolge eine möglichst großes Druckgefälle zu nutzen, so dass auch bei Volllast die Vorteile der Kurbelgehäusebelüftung wirksam werden.The Innovation beats in other words, the aeration line behind in the direction of air flow to connect to the charger and therefore one as possible great pressure drop To use, so that even at full load, the benefits of crankcase ventilation effectively become.
Anscheinend wird in der Fachwelt grundsätzlich davon ausgegangen, dass in den meisten Fällen eine Belüftung des Kurbelgehäuses in Volllastbetrieb nicht erforderlich ist. Wird jedoch beispielsweise bei kaltem Motor ein Fahrzeug unter hoher Last gefahren und dementsprechend der Verbrennungsmotor unter hoher Last betrieben, so ist der Anteil an Kraftstoff im BlowByGas, welches an den Kolben vorbei vom Brennraum in das Kurbelgehäuse des Motors gelangt, besonders hoch. Die wirksame Durchlüftung des Motors auch unter Volllastbedingungen kann daher dazu beitragen, die Beeinträchtigungen der Ölqualität, die ansonsten durch eine Beimischung von Kraftstoff zum Öl zu befürchten sind, zu verringern.Apparently becomes fundamental in the professional world assumed that in most cases ventilation of the crankcase is not required in full load operation. However, for example When the engine is cold, a vehicle has been driven under high load and accordingly the internal combustion engine operated under high load, so is the proportion of fuel in BlowByGas, which is past the pistons of the combustion chamber in the crankcase of the engine gets, especially high. The effective ventilation of the Motors even under full load conditions can therefore help the impairments the oil quality that otherwise to be feared by an admixture of fuel to the oil.
Vorteilhaft kann in der Belüftungsleitung ein Rückschlagventil angeordnet sein, welches nur in Richtung zum Kurbelgehäuse öffnet. Auf diese Weise wird vermieden, dass ölhaltige Gase vom Kurbelgehäuse in den Ansaugtrakt der Brennkraftmaschine angesaugt werden können.Advantageous can in the ventilation duct a check valve be arranged, which opens only in the direction of the crankcase. On This way it is avoided that oily gases from the crankcase in the Intake tract of the internal combustion engine can be sucked.
Vorteilhaft kann vorgesehen sein, dass in der Belüftungsleitung eine Drosselstelle vorgesehen ist, die den Volumenstrom in der Belüftungsleitung begrenzt, so dass insbesondere im Volllastbetrieb ein möglichst großer Volumenstrom der Drosselklappe zugeführt werden kann.Advantageous can be provided that in the ventilation line a throttle point is provided, which limits the volume flow in the ventilation line, so that, in particular, in full load operation as large a volume flow of the throttle valve are supplied can.
Vorteilhaft kann in der Belüftungsleitung ein Belüftungsventil vorgesehen sein, welches bei geringer Motordrehzahl die Belüftungsleitung sperrt oder lediglich zu einem geringen Maße freigibt. Auf diese Weise kann ein stabiles Leerlaufverhalten des Motors unterstützt werden. Dieses Belüftungsventil kann beispielsweise als pneumatisches oder als elektrisches Schaltventil ausgestaltet sein, welches durch die Motorsteuerung bei entsprechenden Betriebsbedingungen des Motors aktiviert wird.Advantageous can in the ventilation duct a ventilation valve be provided, which at low engine speed, the ventilation line locks or releases only to a small extent. In this way a stable idling behavior of the engine can be supported. This ventilation valve For example, as a pneumatic or as an electric switching valve be configured, which by the engine control at appropriate Operating conditions of the engine is activated.
Vorteilhaft kann in an sich bekannter Weise ein Luftmassenmessgerät im Luftansaugtrakt vorgesehen sein. In einem derartigen Fall schließt die Belüftungsleitung vorteilhaft stromabwärts von dem Luftmassenmessgerät an, so dass für die Berechnung des Luftmassenhaushaltes der Brennkraftmaschine die durch die Belüftungsleitung geführte Luft ein Teil der vom Luftmassenmessgerät erfassten Luftmasse ist.Advantageous can in a conventional manner an air mass meter in the air intake tract be provided. In such a case, the vent line advantageously closes downstream of the air mass meter on, so for the calculation of the air mass balance of the internal combustion engine through the ventilation pipe guided Air is part of the air mass detected by the air mass meter.
Vorteilhaft kann eine Kombination von Rückschlagventilen vorgesehen sein, die auch bei stehendem Lader eine Durchlüftung des Kurbelgehäuses sicherstellt, so dass auch bei niedrigeren Drehzahlen, wenn der Lader beispielsweise trägheitsbedingt noch nicht aktiviert ist, eine Durchlüftung des Kurbelgehäuses möglich ist.Advantageous can be a combination of check valves be provided, which even with the charger is a ventilation of the crankcase ensures that even at lower speeds when the Loader, for example, due to inertia not yet activated, a ventilation of the crankcase is possible.
