Abstract
Luftfiltergehäuse für eine Brennkraftmaschine, in dem ein Luftfilter angeordnet ist, das das Luftfiltergehäuse in eine Rohluftseite und eine Reinluftseite trennt, wobei rohluftseitig ein erster Rohlufteinlass für eine Hauptluftansaugung und ein zweiter Rohlufteinlass für eine Notluftansaugung vorgesehen sind, wobei der erste Rohlufteinlass und der zweite Rohlufteinlass bis zum Luftfilter strömungstechnisch voneinander getrennt sind. Durch die erfindungsgemäße Ausgestaltung ist ein vollständiges Verstopfen des Luftfilters durch Eis und Schnee verhindert.An air cleaner housing for an internal combustion engine, in which an air filter is arranged, which separates the air filter housing in a dirty air side and a clean air side, wherein a first unfiltered air inlet for a main air intake and a second unfiltered air intake for emergency air intake are provided on the bluff side, wherein the first unfiltered air intake and the second unfiltered air intake to the air filter fluidly separated from each other. The inventive design a complete clogging of the air filter is prevented by ice and snow.
Description
Die Erfindung betrifft ein Luftfiltergehäuse für eine Brennkraftmaschine mit den Merkmalen aus dem Oberbegriff des Patentanspruchs 1.The invention relates to an air filter housing for an internal combustion engine with the features of the preamble of
Bei einem Personenkraftwagen gelangt beim Fahren bei Schneefall auch Schnee in die Ansaugluftführung des Fahrzeuges. Der Schnee wird durch das Filterelement in der Rohluftschale gehalten und setzt das Filterelement zu, so dass die Brennkraftmaschine keine Verbrennungsluft mehr bekommt. Aus diesem Grund wird in der Regel ein Schneeventil eingesetzt, das einen Bypass öffnet, damit die Brennkraftmaschine über diesen Bypass Verbrennungsluft ansaugen kann.In a passenger car, when driving in snow, snow also enters the intake air duct of the vehicle. The snow is held by the filter element in the Rohluftschale and sets the filter element, so that the internal combustion engine gets no combustion air more. For this reason, a snow valve is usually used, which opens a bypass, so that the internal combustion engine can suck combustion air through this bypass.
Nachteilig an diesem bekannten Stand der Technik sind die Kosten für ein zusätzliches Schneeventil.A disadvantage of this known prior art, the cost of an additional snow valve.
Zur Lösung dieses Problems wird in der deutschen Offenlegungsschrift
Nachteilig an dieser Ausgestaltung ist, dass sich der gesamte Luftfilter mit Schnee und Eis zusetzen kann, so dass der zweite Rohlufteinlass wirkungslos bleibt. Weiter tritt im normalen Betrieb der Brennkraftmaschine aufgrund des Siebes ein erhöhter Druckverlust im Luftfiltergehäuse, auf.A disadvantage of this configuration is that the entire air filter can be clogged with snow and ice, so that the second Rohlufteinlass remains ineffective. Further occurs in normal operation of the internal combustion engine due to the screen, an increased pressure drop in the air filter housing on.
Aufgabe der vorliegenden Erfindung ist es, eine Maßnahme aufzuzeigen, um oben genannten Nachteil zu vermeiden.Object of the present invention is to show a measure to avoid the above drawback.
Diese Aufgabe wird durch das Merkmal im kennzeichnenden Teil des Patentanspruchs 1 gelöst. Erfindungsgemäß wird die Rohlufteinlassführung über eine Leitrippe geteilt, so dass ein Ansaugkanal, der Notluftansaugkanal, an einer Stelle im Motorraum ansaugt, zu der sehr schwer Schnee gelangt und ein Hauptluftansaugkanal an der herkömmlichen Ansaugstelle ansaugt. Diese Leitrippe wird dann im Ansauggeräuschdämpfer verlängert und dichtet zum Luftfilter ab, so dass ein ständig vom Schnee geschützter Bereich entsteht.This object is achieved by the feature in the characterizing part of
Die Ausgestaltung gemäß Patentanspruch 2 ist eine besonders bevorzugte Ausführungsvariante.The embodiment according to
Die Ausgestaltung gemäß Patentanspruch 3 erlaubt einen. sicheren Betrieb der Brennkraftmaschine im Notlauf, auch wenn mit verminderter Leistung.The embodiment according to
Im Folgenden ist die Erfindung anhand eines Ausführungsbeispieles in zwei Figuren näher erläutert.In the following the invention with reference to an embodiment in two figures is explained in more detail.
Bevorzugt ragt der zweite Rohlufteinlass
In einer besonders bevorzugten Ausführungsvariante weist der zweite Rohlufteinlass

Erfindungsgemäß ist die Rohluftführung über eine Leitrippe geteilt, so dass ein Ansaugkanal an einer Stelle ansaugt, zu der sehr schwer Schnee gelangt und ein Ansaugkanal an der herkömmlichen Ansaugstelle ansaugt. Diese Leitrippe wird dann im Ansauggeräuschdämpfer verlängert und dichtet zum Luftfilterelement ab, so dass ein geschützter Bereich für den Luftfilter entsteht.According to the invention, the untreated air duct is divided by a guide rib, so that an intake duct sucks at a location to which snow reaches very heavily and sucks in an intake duct at the conventional intake location. This guide rib is then extended in the intake silencer and seals to the air filter element, so that a protected area for the air filter is formed.
