Description

Die Erfindung geht aus von einer Luftfilterpatrone für ein Lufteinlasssystem einer Brennkraftmaschine sowie von einem Lufteinlasssystem für eine Brennkraftmaschine gemäß den Merkmalen der Oberbegriffe der Ansprüche 1 und 5.The invention relates to an air filter cartridge for an air intake system of a Internal combustion engine and an air intake system for an internal combustion engine according to the features of the preambles of claims 1 and 5.

Zur Reinigung der von einem Verbrennungsmotor angesaugten bzw. zugeführten Verbrennungsluft sind Lufteinlasssysteme mit einer darin angeordneten Luftfilterpatrone bekannt (siehe z.B. DE 197 56 247 Al). Die Luftfilterpatrone weist dabei beispielsweise ein in Längsrichtung gefaltetes Papierfilterelement auf, welches den mit der angesaugten Luft mitgeführten Staub oder andere Verunreinigungen zurückhält.For cleaning the sucked or supplied by an internal combustion engine Combustion air are air intake systems with an air filter cartridge arranged therein known (see for example DE 197 56 247 Al). The air filter cartridge has, for example a longitudinally folded paper filter element, which with the sucked Traps airborne dust or other contaminants.

Es ist weiterhin allgemein bekannt - in Strömungsrichtung gesehen - hinter dem Luftfiltergehäuse die dem Motor zugeführte Verbrennungsluftmenge durch einen Luftmassenmesser, z.B. in Form eines HFM, zu bestimmen, damit der für eine optimale Verbrennung erforderliche Kraftstoff zugeführt werden kann. Untersuchungen haben gezeigt, dass über die Lebensdauer der Luftfilterpatrone das HFM-Signal verfälscht wird. Eine mögliche Ursache dafür liegt darin, dass sich der Strömungsverlauf der zugeführten Verbrennungsluft aufgrund der im vorderen Bereich der Luftfilterpatrone beginnenden Verschmutzung des Luftfilterpapiers verändert, so dass eine entsprechende Kennliniendrift des Luftmassenmessers feststellbar ist.It is also well known - seen in the flow direction - behind the Air filter housing, the amount of combustion air supplied to the engine through a Air mass meter, e.g. in the form of an HFM, to determine that for optimal Combustion required fuel can be supplied. Have investigations shown that over the life of the air filter cartridge, the HFM signal is corrupted. One possible reason for this is that the flow of the supplied Combustion air due to the beginning in the front of the air filter cartridge Pollution of the air filter paper changed, so that a corresponding Characteristic drift of the air mass meter is detectable.

Aufgabe der Erfindung ist es daher, sicherzustellen, dass über die Lebensdauer der Luftfilterpatrone das Signal des Luftmassenmessers entsprechend der zugeführten Luftmasse unverfälscht bleibt.The object of the invention is therefore to ensure that over the life of Air filter cartridge the signal of the air mass meter according to the supplied Air mass remains unadulterated.

Die Aufgabe der Erfindung wird durch die im Anspruch 1 sowie im Anspruch 5 angegebenen Merkmale gelöst.The object of the invention is characterized by that in claim 1 and in claim 5 specified characteristics solved.

Dadurch, dass in der Luftfilterpatrone eine Drosselblende angeordnet ist, kann die Kennlinie des Luftmassenmessers über die gesamte Lauf- bzw. Lebenszeit des Luftfilters konstant gehalten werden, so dass eine stabile, sichere und emissionsarme Verbrennung sichergestellt ist.The fact that in the air filter cartridge an orifice is arranged, the Characteristic of the air mass meter over the entire running or lifetime of the air filter be kept constant, allowing a stable, safe and low-emission combustion is ensured.

Weitere, die Erfindung ausgestaltende Merkmale sind in den Unteransprüchen aufgeführt.Further, the invention ausgestaltende features are listed in the subclaims.

Eine für die Erfassung des HFM-Signals optimale Lage der Drosselblende ergibt sich, wenn diese -bezogen auf die Längsachse der Luftfilterpatrone- im wesentlichen senkrecht dazu und -bezogen auf die Länge I der Luftfilterpatrone- im wesentlichen mittig im Hohlraum der Luftfilterpatrone angeordnet ist.An optimum position of the orifice plate for the detection of the HFM signal results, if this-related to the longitudinal axis of the Luftfilterpatrone- substantially perpendicular for this purpose and -related to the length I of the air filter cartridge- substantially in the center Cavity of the air filter cartridge is arranged.

Die Drosselblende ist vorteilhaft aus einer Lochscheibe mit kreisförmigen Öffnungen gebildet.The orifice is advantageous from a perforated disc with circular openings educated.

Der Mantelkörper der Luftfilterpatrone weist eine Rippenstruktur auf, aus der die Lochscheibe einstückig herausgebildet ist. Dabei ist die Rippenstruktur vorzugsweise aus einem Kunststoff hergestellt.The jacket body of the air filter cartridge has a rib structure, from which the Perforated disk is formed integrally. In this case, the rib structure is preferably made made of a plastic.

Die Erfindung betrifft weiterhin ein Lufteinlasssystem für eine Brennkraftmaschine mit einem Luftfiltergehäuse, das einen Reinluftauslass und Rohlufteinlass aufweist, wobei im Luftfiltergehäuse eine Luftfilterpatrone gemäß einem der Ansprüche 1 bis 4 aufgenommen ist.The invention further relates to an air intake system for an internal combustion engine with an air cleaner housing having a clean air outlet and unfiltered air intake, wherein in Air filter housing an air filter cartridge according to one of claims 1 to 4 is included.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt, das nachstehend näher beschrieben ist.In the drawing, an embodiment of the invention is shown below is described in more detail.

Beschreibung des AusführungsbeispielsDescription of the embodiment

In Fig. 1 ist ein Lufteinlasssystem für eine Brennkraftmaschine dargestellt, das ein Luftfiltergehäuse 2 aufweist, in dem eine Luftfilterpatrone 4 angeordnet ist. Die im Querschnitt ovalförmig ausgebildete Luftfilterpatrone 4 ist dabei über einen am Luftfiltergehäuse 2 vorgesehenen Gehäusedeckel 6 zugänglich. Das Luftfiltergehäuse 2 weist einen Einlassstutzen 8 für die Rohluft sowie ein Auslassrohr 10 für die durch die Luftfilterpatrone 4 gereinigte Verbrennungsluft auf. Das Auslassrohr 10 ist dabei mit einem nicht dargestellten Drosselklappengehäuse verbunden, über das die Verbrennungsluft entsprechend dosiert, dem Zylinderkopf der Brennkraftmaschine zugeführt wird. In Strömungsrichtung gesehen hinter dem Auslassrohr 10 ist ein Luftmassenmesser, z.B. in Form eines HFM befestigt, der den Luftmassenstrom entsprechend erfasst, bevor er über das Drosselklappengehäuse in den Brennraum gelangt.In Fig. 1, an air intake system for an internal combustion engine is shown, the one Air filter housing 2, in which an air filter cartridge 4 is arranged.

Hohlraum 15 der Luftfilterpatrone 4 gelangt. Von dort aus strömt die gefilterte bzw. gereinigte Rohluft als Reinluft über das Auslassrohr 10 in den Ansaugtrakt der Brennkraftmaschine. Wie insbesondere in den Fig. 3 und 4 erkennbar, ist - bezogen auf die Längsachse 16 der Luftfilterpatrone 4 - im wesentlichen senkrecht dazu und -bezogen auf die Länge I der Luftfilterpatrone 4- im wesentlichen mittig eine Drosselblende 18 angeordnet, die in Form einer Lochscheibe mit kreisförmigen Öffnungen 20 ausgebildet ist. Die Lochscheibe 18 ist dabei einstückig aus der Rippenstruktur 12a des Mantelkörpers 12 herausgebildet, wobei die Rippenstruktur 12a vorzugsweise aus einem Kunststoffmaterial besteht.The air filter cartridge 4 has a jacket body 12 made of a rib structure 12a. The individual ribs of the rib structure 12a are spaced apart from each other and form between them corresponding cavities 12b, on the combustion air - as shown the arrows shown in Fig. 2 - on the on the lateral surface of the air filter cartridge. 4 arranged filter paper 14 in the interior or cavity 15 of the air filter cartridge 4th arrives. From there, the filtered or purified raw air flows through the system as clean air Outlet pipe 10 in the intake tract of the internal combustion engine. As in particular in FIGS. 3 and 4 can be seen, is - based on the longitudinal axis 16 of the air filter cartridge 4 - in essential perpendicular thereto and - related to the length I of the air filter cartridge 4- im essentially centrally disposed an orifice 18, which in the form of a perforated disc with circular openings 20 is formed.
