Abstract
Description
Die Erfindung betrifft eine Einrichtung zur Zufuhr von An saugluft in den Rohraum eines Luftansaugfilter-Gehäuses ei nes Kraftfahrzeugmotors.The invention relates to a device for supplying to suction air into the tube space of an air intake filter housing nes motor vehicle engine.
Die Ansaugöffnung einer derartigen Einrichtung liegt bei Kraftfahrzeugen üblicherweise in einer Höhe, bei der beim Fahren des Kraftfahrzeuges durch auf dem Fahrweg stehendes Wasser dieses nicht in die Ansaugöffnung eindringen kann.The suction opening of such a device is included Motor vehicles usually at a height at which Driving the motor vehicle by standing on the road Water cannot penetrate the suction opening.
Zu einem Eindringen von Wasser in die Ansaugöffnung kann es jedoch kommen, wenn ein Fahrzeug, insbesondere ein Personen kraftwagen mit einem niedrigen Motorraum, durch extrem hoch stehendes Wasser fährt. Solche Fälle können bei schlechten Fahrwegen oder auch im Falle von Überschwemmungen vorkommen.Water can enter the suction opening however, come when a vehicle, especially a person motor vehicles with a low engine compartment, due to extremely high stagnant water moves. Such cases can be bad Driveways or in the event of flooding.
Hier Abhilfe zu schaffen, ohne die Ansaugöffnung generell an eine für den normalen Fahrzeugbetrieb ungünstig hohe Stelle legen zu müssen, ist das Problem, mit dem sich die Erfindung beschäftigt. To remedy this without generally opening the intake opening a position that is unfavorably high for normal vehicle operation Having to lay is the problem with which the invention is concerned employed.
Eine Lösung hierfür zeigt eine Ausführung nach den kenn zeichnenden Merkmalen des Patentanspruchs 1 auf.A solution for this is shown in an execution according to the kenn drawing features of claim 1.
Diese Lösung beruht auf dem Gedanken, die für den Normalbe trieb wirksame Ansaugöffnung durch auf dem Fahrweg extrem hoch stehendes Wasser automatisch durch das anstehende Was ser selbst verschließen zu lassen. Bei verschlossener Haupt- Ansaugöffnung kann dann weiterhin durch eine kleinere höher und damit sicher vor einem Wassereintritt gelegene Nebenöff nung Ansaugluft angesaugt werden. Für einen solchen Fall, der praktisch nur eine Notsituation darstellt, genügt dann ein geringerer Luftansaugstrom, der im Prinzip lediglich so groß sein muß, daß ein Fahrbetrieb durch den Motor gerade noch sicher gewährleistet ist.This solution is based on the idea that is for the normal effective suction opening through on the driveway extremely high water automatically by what is pending to have it sealed itself. When the main Intake opening can then continue through a smaller higher and thus secondary openings that are safe from water ingress Intake air can be sucked in. In such a case, which is practically only an emergency situation is then sufficient a lower air intake flow, which in principle is only so must be large that driving by the engine straight is still guaranteed.
Zweckmäßige Ausgestaltungen der erfindungsgemäßen Lösung sind Gegenstand der Unteransprüche und werden im Zusammen hang mit der Beschreibung eines Ausführungsbeispieles noch im einzelnen erläutert werden.Appropriate configurations of the solution according to the invention are the subject of the subclaims and are together hang with the description of an embodiment are explained in detail.
Ein solches Ausführungsbeispiel ist in der Zeichnung darge stellt. Such an embodiment is shown in the drawing poses.

Fig. 1 die Anordnung einer erfindungsgemäßen Ansaugluftein richtung im Motorraum eines Personenkraftwagens in schematischer Darstellung, Fig. 1 shows the arrangement according to the invention a Ansaugluftein direction in the engine compartment of a passenger car in a schematic representation;
Fig. 2 einen Längsschnitt durch die Ansaugeinrichtung nach Fig. 1. FIG. 2 shows a longitudinal section through the suction device according to FIG. 1.
In Fahrtrichtung vor dem Motor ist in dem Motorraum eines Kraftfahrzeuges ein Luftfilter-Gehäuse 1 mit einem Hauptan saugstutzen 2 und einem Nebenansaugstutzen 3 angeordnet. Der Hauptansaugstutzen 2 besitzt eine an dem vorderen Ende des Motorraumes liegende Ansaugöffnung 4. Der Nebenansaugstutzen 3 ist nach lotrecht oben gerichtet und besitzt eine Ansau göffnung 5, die oberhalb der Ansaugöffnung 4 liegt. An die Ansaugöffnung 5 kann noch eine Verlängerungsleitung 6 ange schlossen sein, die noch eine weiter oben liegende An saugöffnung 7 besitzt.In the direction of travel in front of the engine, an air filter housing 1 is arranged in the engine compartment of a motor vehicle with a Hauptan intake port 2 and a secondary intake port 3 . The main intake manifold 2 has an intake opening 4 located at the front end of the engine compartment. The secondary intake 3 is directed vertically above and has a suction opening 5 , which lies above the suction opening 4 . At the suction opening 5 , an extension line 6 can be connected, which still has a higher-lying suction opening 7 .
Unterhalb des Hauptansaugstutzens 2 ist ein nach unten offe nes Rohr 8 vorgesehen. In dieses Rohr kann Wasser eindrin gen, wenn dieses auf dem Fahruntergrund entsprechend hoch ansteht, wie dies in Fig. 1 angedeutet ist. Das untere Ende dieses Rohres 8 kann in Fahrtrichtung gekrümmt sein, wie es in Fig. 1 strichpunktiert angedeutet ist. Dadurch kann der von in das Rohr 8 hineinreichendem Wasser ausgehende stati sche Druck noch durch einen von der Fahrgeschwindigkeit er zeugten dynamischen Zusatzdruck erhöht werden.Below the main intake 2 , a downwardly open tube 8 is provided. Water can penetrate into this tube if it stands high on the driving surface, as indicated in FIG. 1. The lower end of this tube 8 can be curved in the direction of travel, as is indicated by dash-dotted lines in FIG. 1. As a result, the static pressure coming from the pipe 8 into the water can be increased by a dynamic additional pressure generated by the driving speed.
Das obere offene Ende des Rohres 8 ist über einen dicht mit dem Rohr verbundenen Faltenbalg 9 dicht mit einer schwenkba ren Klappe 10 verbunden. Die Klappe 10 ist in den Hauptan saugstutzen 2 hinein schwenkbar. Bei voll in den Hauptan saugstutzen 2 eingeschwenkter Position verschließt die Klap pe 10 den Strömungsquerschnitt des Hauptstutzens 2. Um einen dichten Verschluß zu gewährleisten, sind in den Hauptansaug stutzen 2 ebene Anlageflächen 11 eingeformt, an denen die Klappe 10 über eine an dieser befestigte Dichtung 12 dicht anliegen kann.The upper open end of the tube 8 is tightly connected via a bellows 9 connected to the tube tightly with a schwenkba ren flap 10 . The flap 10 can be swiveled into the main inlet 2 . When fully in the suction nozzle 2 Hauptan the pivoted position closes the Klap pe 10 the flow cross section of the main nozzle. 2 In order to ensure a tight seal, 2 flat contact surfaces 11 are formed in the main intake, on which the flap 10 can fit tightly via a seal 12 attached to it.
Die Klappe 10 ist durch eine Feder 13 in Offenstellung vor gespannt. In dieser Offenstellung stellt sie ein Teil der Außenwand des Hauptansaugstutzens 2 dar, wodurch bei offener Klappe 10 ein umfangsmäßig dicht geschlossener Hauptansaug stutzen 2 vorliegt.The flap 10 is tensioned by a spring 13 in the open position. In this open position, it represents part of the outer wall of the main intake 2 , so that when the flap 10 is open, a circumferentially tightly closed main intake 2 is present.
Fährt das Fahrzeug durch derart hohes Wasser, daß dieses in das Rohr 8 eindringt, so bewirkt die Kraft des eingedrunge nen Wassers eine Luftverdrängung in Richtung der Klappe 10. Dadurch wird die Klappe 10 in Schließstellung bewegt, indem sich der Faltenbalg 9 entsprechend ausdehnt. Bei geschlosse ner Klappe 10 saugt der Motor die notwendige Verbrennungs luft ausschließlich über den Nebenansaugstutzen 3 mit der hoch liegenden Ansaugöffnung 5 an. Bei geöffneter Klappe 10, das heißt bei üblichen Fahrten des Kraftfahrzeuges, bei de nen kein in das Rohr 8 hinein ragendes Wasser auf dem Fahruntergrund vorhanden ist, erfolgt das Ansaugen zum über wiegenden Teil durch den Hauptansaugstutzen 2, wobei ein ge ringer Teil der Ansaugluft auch über den Nebenansaugstutzen 3 dem Filtergehäuse zugeführt wird.If the vehicle travels through such high water that it penetrates into the tube 8 , the force of the water penetrated causes an air displacement in the direction of the flap 10 . As a result, the flap 10 is moved into the closed position by the bellows 9 expanding accordingly. When the valve 10 is closed, the engine sucks the necessary combustion air exclusively through the secondary intake 3 with the intake port 5 located high. When the flap 10 is open, that is to say during normal motor vehicle journeys, in which there is no water protruding into the tube 8 on the driving surface, the suction takes place to the predominant part through the main intake pipe 2 , with a small part of the intake air also is fed to the filter housing via the secondary intake 3 .
Eine geschlossene Position der Klappe 10, die durch ein Fah ren durch tiefes Wasser bedingt ist, wird durch den dann in dem Rohraum des Filters entstehenden hohen Unterdruck, der durch die geringe Menge an angesaugter Luft durch den Neben ansaugstutzen 3 verursacht ist, in der Schließwirkung noch zusätzlich unterstützt. Sobald das Fahrzeug nicht mehr in derart tiefem Wasser fährt, daß das Rohr 8 in das Wasser eintaucht, öffnet sich die Klappe 10 unter der Vorspannung der Feder 13 automatisch. Dies wird auch nicht durch einen Unterdruck in dem Rohraum des Filtergehäuses 1 grundsätzlich verhindert, da bei Motorlastwechseln der Unterdruck zumin dest zeitweise verloren geht.A closed position of the flap 10 , which is caused by driving through deep water, is caused by the high vacuum then created in the tube space of the filter, which is caused by the small amount of air sucked in by the secondary intake 3 , in the closing action additionally supported. As soon as the vehicle no longer travels in such deep water that the tube 8 is immersed in the water, the flap 10 opens automatically under the bias of the spring 13 . This is also not fundamentally prevented by a vacuum in the tube chamber of the filter housing 1 , since the vacuum is at least temporarily lost when the engine load changes.
Da vor einem Schließen des Hauptansaugstutzens 2 Spritzwas ser in den Rohraum des Filtergehäuses 1 eintreten kann, ist dieses Gehäuse an der untersten Stelle mit einem unter im Inneren des Rohraumes anstehendem Wasser sich selbständig öffnenden Abflußventil 14 versehen. In seiner einfachsten Ausführungsform kann dies ein sogenanntes Lippenventil sein.Since before the main intake 2 Spritzwas water can enter the tube space of the filter housing 1 , this housing is provided at the lowest point with a water opening in the interior of the tube space automatically opening drain valve 14 . In its simplest embodiment, this can be a so-called lip valve.
