Description

Die Erfindung bezieht sich auf eine Brennkraftmaschine mit einer Ansauganlage nach dem Oberbegriff des Anspruchs 1.The invention relates to an internal combustion engine with an intake system the preamble of claim 1.

In einer Ansauganlage einer Brennkraftmaschine entstehen aufgrund eines variablen Luftdurchsatzes zu den einzelnen Zylindern im Zylinderkopf Luftschallgeräusche, die über den Behälter der Anlage und sonstige Bauteile nach außen weitergeleitet werden und eine akustische Komfortverschlechterung darstellen.In an intake system of an internal combustion engine arise due to a variable Air flow rate to the individual cylinders in the cylinder head be forwarded to the outside via the system container and other components and represent an acoustic deterioration in comfort.

Aus der DE-C-37 42 057 ist eine Ansauganlage für eine Brennkraftmaschine mit einem Behälter, Ansaugstutzen und mehreren Einzelsaugrohren sowie einem Luftreinigungssystem bekannt.From DE-C-37 42 057 is an intake system for an internal combustion engine with a Container, intake manifold and several individual intake pipes and one Air purification system known.

Aus der GB-A-162 934 ist es bei Auspuffschalldämpfern zur Schallverminderung bekannt, den Einlaßstutzen mit einem Führungsrohr ins Innere des Schalldämpfers zu verlängern.From GB-A-162 934 it is used for exhaust silencers for noise reduction known to the inlet port with a guide tube inside the silencer extend.

Aus der EP 0 382 596 A1 ist eine Brennkraftmaschine mit einer Ansauganlage bekannt, die einen Ansaugstutzen und Einzelsaugrohre umfaßt und der Ansaugstutzen durch ein freistehend in den Behälter führendes Lüftungsrohr verlängert ist, das quer zu den Einzelsaugrohren verläuft und seine Mündungsöffnung in einer Mittelebene zwischen den Einzelsaugrohren angeordnet ist und die Mündungsöffnung die Einzelsaugrohre in zwei Gruppen aufteilt. EP 0 382 596 A1 describes an internal combustion engine with an intake system known, which includes an intake manifold and individual intake pipes and the intake manifold is extended by a free-standing ventilation pipe leading into the container, which runs across runs to the individual intake pipes and its mouth opening in a central plane is arranged between the individual suction pipes and the mouth opening Divides individual suction pipes into two groups.

Aufgabe der Erfindung ist es, eine Brennkraftmaschine zu schaffen, die eine Ansauganlage umfasst, in der eine Reduzierung von Luftschallgeräuschen bewirkt wird.The object of the invention is to provide an internal combustion engine which includes an intake system in which a reduction of Airborne noise is caused.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. Weitere vorteilhafte Merkmale beinhalten die Unteransprüche.This object is achieved by the characterizing features of claim 1 solved. Other advantageous features include Subclaims.

Zur Reduzierung von Luftschallgeräuschen ist im Behälter der Ansauganlage ein Luftführungsrohr vorgesehen, das eingangsseitig am Ansaugstutzen des Behälters befestigt ist und freiliegend in den Behälter hineinragt. Dieser Behälter gewährleistet eine verteilte Aufladung der Zylinder infolge der wesentlichen Trennung der Verbindungen durch das Volumen des Behälters. Andererseits führt die gegenseitige Unabhängigkeit des Welleneffekts in den Einzelsaugrohren der Zylinder zu einer schärferen Entwicklung der Gas-Resonanz-Schwingungen in jedem einzelnen Saugrohr.To reduce airborne noise, the Intake system provided an air duct, which on the input side Intake of the container is attached and exposed in the Container protrudes. This container ensures a distributed Charging of the cylinders due to the essential separation of the Connections by the volume of the container. On the other hand, the mutual independence of the wave effect in the individual intake pipes the cylinder to a sharper development of the Gas resonance vibrations in every single intake manifold.

Infolge der Asymmetrie der akustischen, vom Behälter erzeugten Belastungen, sind die Belastungen auf die Einzelsaugrohre der einzelnen Zylinder verschieden und es führt zu einer kleineren Nichtübereinstimmung der Resonanzfrequenz in den einzelnen Einzelsaugrohren. Deshalb werden die Resonanzschwingungen (auf ihrer Resonanzfrequenz), die in einem der Zylinder entstehen, nicht durch die Schwingungen gedämpft, die im Behälter durch die Einzelsaugrohre entstehen und sogar wenn die Anfangsimpulse von den Zylindern kompensiert sind; denn sie laufen in Gegenphase. Die zweite ungünstige Erscheinung ist mit der Erregung der ersten asymmetrischen Form der Gasschwingungen im Behälter verbunden. Regelmäßig liegt ihre Frequenz nahe zu einer Eigenfrequenz der Gasschwingung im Einzelsaugrohr, was zu einer intensiven Schallausstrahlung aus dem System führt, besonders auf den Frequenzen, die mit den ungeraden harmonischen der Hauptfrequenz des Ansaugprozesses übereinstimmen.Due to the asymmetry of the acoustic generated by the container Loads are the loads on the individual suction pipes of the individual Cylinder different and it leads to a smaller one Mismatch in resonance frequency in each Individual suction pipes. Therefore the resonance vibrations (on their Resonance frequency), which arise in one of the cylinders, not by the Vibrations dampened in the tank by the individual suction pipes arise and even when the initial impulses from the cylinders are compensated; because they run in opposite phase. The second inconvenient Appearance is the excitement of the first asymmetrical form of Gas vibrations connected in the container. Their frequency is regular close to a natural frequency of the gas vibration in the single intake manifold, leading to intensive sound radiation from the system the frequencies that match the odd harmonics of the main frequency of the Intake process match.

Zur Beseitigung dieser nachteiligen Erscheinung wird in den Behälter ein Luftführungsrohr eingesetzt, das koaxial zu einer Mittenachse mit der Mittenachse des Behälterraumes angeordnet und eingangsseitig im Ansaugstutzen des Behälters befestigt wird. Dieser verbindet den Behälter mit dem Luftzuführungs- und Luftreinigungssystem.To eliminate this disadvantageous phenomenon, put in the container Air duct used, which is coaxial with a central axis with the Center axis of the container space arranged and on the input side in Intake connector of the container is attached. This connects the Containers with the air supply and air purification system.

Die im Behälter vorgesehene Mündungsöffnung des Luftführungsrohres befindet sich in einer Ebene, die senkrecht zur Seitenwand des Behälters angeordnet ist und die einen etwa gleichen Abstand von den Mittenachsen der Einzelsaugrohre des zweiten und dritten Zylinders haben.The mouth opening of the air guide tube provided in the container is in a plane that is perpendicular to the side wall of the container is arranged and the approximately the same distance from the center axes of the individual intake pipes of the second and third cylinders.

Das freie Ende des Luftführungsrohres ist teilweise perforiert und weist radiale Durchströmöffnungen auf.The free end of the air duct is partially perforated and has radial flow openings.

Dieses Vorhandensein eines auf eine bestimmte Weise angeordneten Luftführungsrohres bewirkt, daß die akustische Belastung auf die Zylinder, die in einer Gegenphase arbeiten, symmetrisch ist und beseitigt die asymmetrische Erregung in den niedrigsten Frequenzen.This presence of one arranged in a certain way Air duct causes the acoustic load on the Cylinder working in an opposite phase, is symmetrical and eliminates asymmetrical excitation at the lowest frequencies.

Außerdem befindet sich die Mündungsöffnung des Luftführungsrohres in der Nähe eines Knotens (Nulldurchgang) einer ersten Gaseigenschwingung des Behälters der Ansauganlage. Hierdurch wird auch bei einer Resonanzerregung verhindert, daß eine Übertragung der akustischen Energie durch das Luftführungsrohr in Richtung Einlaßmündung und dadurch an die Umgebung erfolgt.In addition, the mouth of the air duct is in the Proximity of a node (zero crossing) of a first natural gas oscillation of the Of the intake system. This will also with a Resonance excitation prevents transmission of the acoustic Energy through the air duct towards the inlet mouth and thereby to the environment.
