Abstract
Description
Die
Erfindung betrifft ein Olabscheidesystem für eine Brennkraftmaschine gemäß dem Oberbegriff des
Anspruchs 1 (
Nach einer in der Europäischen Union für PKW gültigen Vorschrift darf im Kurbelgehäuse einer Brennkraftmaschine kein Überdruck auftreten, und zwar in keinem Betriebszustand des Motors. Ein Überdruck kann beispielsweise im Leerlauf von Diesel-Motoren oder bei Volllast im niedrigen Drehzahlbereich von Otto-Motoren auftreten. In solchen Betriebszuständen ist im Ansaugtrakt fast kein Unterdruck vorhanden, der als treibende Kraft für die Ölabscheidung aus Blow-by-Gasen erforderlich ist. Das durch den Strömungswiderstand im Ölabscheider erzeugte Druckgefälle kann in diesen Betriebszuständen zu unzulässigem Überdruck im Kurbelgehäuse führen.To one in the European Union for cars valid Regulation may be in the crankcase an internal combustion engine no overpressure occur, in no operating condition of the engine. An overpressure For example, when idling diesel engines or at full load occur in the low speed range of gasoline engines. In such operating conditions There is almost no negative pressure in the intake tract acting as driving Force for the oil separation from blow-by gases is required. That through the flow resistance in the oil separator generated pressure gradient can in these operating conditions to impermissible overpressure in the crankcase.
Mit zunehmender Betriebsdauer einer Brennkraftmaschine steigt die Menge an Blow-by-Gas wegen des Verschleißes von Motorkomponenten, wie Kolbenringen, Kolben und Laufbuchsen, kontinuierlich an. Mit zunehmender Menge von Blow-by-Gas steigt der Druckverlust im Ölabscheider, was die Gefahr des Überschreitens der genannten Vorschrift erhöht.With increasing operating time of an internal combustion engine increases the amount to blow-by gas because of the deterioration of engine components, such as Piston rings, pistons and liners, continuously on. With increasing Amount of blow-by gas increases the pressure drop in the oil separator, what the danger of crossing of that provision.
Um dem zu begegnen, werden im Stand der Technik Druckregelventile in die Ölabscheidesysteme eingebaut, um den Druck im Kurbelgehäuse innerhalb der festgelegten Grenzwerte zu halten.Around In the art, pressure control valves are used in the prior art the oil separator systems fitted to the pressure in the crankcase within the specified To keep limits.
Bei
einer üblichen
Anordnung ist das Druckregelventil (kurz DRV) jedoch in Strömungsrichtung hinter
dem Ölabscheider
angeordnet. Hierbei wird der Druck hinter dem Ölabscheider, nicht aber der Druck
im Kurbelgehäuse
direkt geregelt. Im Kurbelgehäuse
stellt sich bei einer solchen Anordnung ein Druck in Höhe des geregelten
Sollwertes plus dem mit zunehmender Betriebsdauer ansteigenden Druckgefälle oder
Druckverlust im Ölabscheider
ein. Ein zu hoher Unterdruck oder ein Überdruck im Kurbelgehäuse wird
auf diese Weise nicht erfaßt
(
Es
ist auch ein Ölabscheidesystem
bekannt, bei dem ein Druckregelventil in Strömungsrichtung vor dem Ölabscheider
angeordnet ist (
Es
ist auch bekannt, in einer Brennkraftmaschine ein membrangesteuertes
Ventil zur Kurbelgehäuseentlüftung einzusetzen
und diesem Ventil einen Dämpfungsraum
vorzuschalten, der einem Flattern des Ventils infolge von Druckpulsationen
vorbeugen soll (
Der Erfindung liegt die Aufgabe zugrunde, ein Ölabscheidesystem zu schaffen, das der eingangs genannten Vorschrift in allen Betriebszuständen einer Brennkraftmaschine auch bei deren fortgeschrittener Gebrauchsdauer genügt.Of the Invention has for its object to provide an oil separation system, that of the aforementioned provision in all operating conditions of a Internal combustion engine even with their extended service life enough.
Zur Lösung dieser Aufgabe dient Patentanspruch 1.to solution This object is served by claim 1.
Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.advantageous Embodiments of the invention are specified in the subclaims.
Die Erfindung ist im folgenden anhand einer schematischen Zeichnung mit weiteren Einzelheiten näher erläutert.The The invention is described below with reference to a schematic drawing with more details explained.
Die Zeichnung zeigt das Schema eines Ölabscheidesystems gemäß der Erfindung in Einbaulage der Brennkraftmaschine in einem Fahrzeug.The Drawing shows the scheme of a Ölabscheidesystems according to the invention in installation position of the internal combustion engine in a vehicle.
