Description
Die Erfindung betrifft eine Anordnung eines Luftfiltergehäuses für eine Brennkraftmaschine im Motorraum eines Kraftfahrzeuges mit den Merkmalen aus dem Oberbegriff des Patentanspruchs 1.The The invention relates to an arrangement of an air filter housing for an internal combustion engine in the engine compartment of a motor vehicle with the features of the preamble of claim 1

Patentschrift
Aufgabe der vorliegenden Erfindung ist es, ein gattungsgemäßes Luftfiltergehäuse besonders Platz sparend in den Motorraum eines Kraftfahrzeuges zu integrieren.task The present invention is particularly space for a generic air filter housing saving to integrate into the engine compartment of a motor vehicle.
Diese Aufgabe wird durch das Merkmal im kennzeichnenden Teil des Patentanspruchs 1 dadurch gelöst, dass der Ansaugbereich geodätisch oberhalb eines Kühlmittelwärmetauschers der Brennkraftmaschine angeordnet ist und von dem Motorraum vor dem Ansaugbereich zumindest ein Luftleitelement gebildet ist und in dem Luftführungskanal ein Luftmengenmesselement angeordnet ist.These The object is achieved by the feature in the characterizing part of the claim 1 solved by that the intake area geodetically above a coolant heat exchanger the internal combustion engine is arranged and from the engine compartment the suction at least one air guide is formed and in the air duct Air quantity measuring element is arranged.
Durch die erfindungsgemäße Ausgestaltung wird die Luft durch den Ansaugbereich, allgemein Ansaugschnorchel genannt, oberhalb des Kühlmittelwärmetauschers angesaugt. Durch das von der Karosserie gebildete zumindest eine Luftleitelement am Eintritt in das Luftfiltergehäuse, wird die Rohluft in den tiefen Teil des Luftfiltergehäuses umgelenkt, wo Wasser und Grobpartikel ausgeschieden und drainiert werden sodass der Filter weniger verschmutzt, bzw. angefeuchtet wird. Dies ist insbesondere für selbstzündende Brennkraftmaschinen wichtig, da über die der Brennkraftmaschine zugeführte Luftmasse die aktuell notwendige Brennstoffmenge ermittelt wird. Feuchte Ansaugluft kühlt jedoch einen Luftmassenmesser schneller ab als Trockene, wodurch bei feuchter Ansaugluft eine zu große Ansaugluftmasse ermittelt wird und somit eine falsche Brennstoffmenge der Brennkraftmaschine zugeführt wird. Weiter wird über eine Einströmöffnung mit einem Fangkragen die vorgereinigte Rohluft dem Luftfilter zugeführt. Die nach dem Luftfilter gereinigte Luft strömt anschließend zu einem Luftmengenmesselement, das ebenfalls im Luftfiltermodul integriert ist.By the embodiment of the invention will the air through the intake area, commonly called intake snorkel, above the coolant heat exchanger sucked. Due to the body formed by at least one Air guide at the entrance to the air filter housing, the unfiltered air in the deep part of the air filter housing redirected where water and coarse particles are excreted and drained so that the filter is less polluted or moistened becomes. This is especially for self-igniting internal combustion engines important, over there the supplied to the internal combustion engine Air mass, the currently required amount of fuel is determined. Moist intake air cools However, an air mass meter faster than dry, thereby If the intake air is too moist, the intake air mass is too high is and thus a wrong amount of fuel of the internal combustion engine supplied becomes. Next will be over an inflow opening with a Fang collar the pre-cleaned raw air supplied to the air filter. The air cleaned after the air filter then flows to an air flow meter, which is also integrated in the air filter module.
In einer weiteren Ausgestaltungsvariante kann gemäß Patentanspruch 2 in Hauptströmrichtung vor dem Luftmengenmesselement ein weiteres Strömungselement angeordnet sein, wodurch die Luft vor der Luftmengenmessung gleichgerichtet wird und eine genauere und präzisere Messung möglich ist. Zusätzlich wird der Druckverlust durch das Strömungsleitelement zum Luftmengenmesselement verringert und die Anströmverhältnisse des Luft mengenmesselementes verbessert, wodurch die Kennlinie des Luftmengenmesselementes verbessert, d. h. linearisiert wird.In A further embodiment variant can according to claim 2 in the main flow direction be arranged before the air flow measuring element another flow element, whereby the air is rectified before the air flow measurement and a more precise and precise Measurement is possible. additionally the pressure loss is reduced by the flow guide to the air flow measuring element and the flow conditions the air quantity measuring element improved, whereby the characteristic of the Air quantity measuring element improved, d. H. is linearized.
Gemäß Patentanspruch 3 ist das Luftmengenmesselement ein besonders robuster Heißfilmluftmassensensor.According to claim 3, the air flow meter is a particularly robust hot film air mass sensor.
Ferner verfügt die Rohluftschale gemäß Patentanspruch 4 über eine Öffnung, durch die die zuvor beschriebene vorab abgeschiedene Feuchtigkeit sowie grobe Schmutzpartikel ausgeschieden werden. Durch diese Maßnahme ist die Wasserschlaggefahr minimiert und die Lebensdauer des Luftfilters verlängert.Further has the Rohluftschale according to claim 4 over an opening, by the previously deposited pre-separated moisture as well coarse dirt particles are excreted. By this measure is minimizes the risk of water hammer and extends the service life of the air filter.
Gemäß Patentanspruch 5 kann an die Rohluftschale und/oder an die Reinluftschale ein zusätzlicher Resonator angeordnet sein. Durch diese Maßnahme werden ungewünschte Geräusche wirkungsvoll gedämpft.According to claim 5 may be an additional to the Rohluftschale and / or the clean air bowl Resonator can be arranged. By this measure, unwanted noises become effective attenuated.
Die Anordnung gemäß Patentanspruch 6 erlaubt eine schwingungstechnische Entkopplung zwischen Luftfiltergehäuse und Brennkraftmaschine.The Arrangement according to claim 6 allows a vibration control decoupling between the air filter housing and Internal combustion engine.
Im Folgenden ist das erfindungsgemäße Luftfiltergehäuse anhand eines bevorzugten Ausführungsbeispieles in zwei Figuren näher erläutert.in the Below is the air filter housing according to the invention a preferred embodiment closer in two figures explained.
