Abstract
Description
Die Erfindung betrifft eine Saugrohranlage mit einem Resonanzbehälter für eine mehrzylindrige Brennkraftmaschine der im Oberbegriff des Anspruchs 1 angegebenen Gattung.The The invention relates to an intake manifold with a resonant tank for a multi-cylinder internal combustion engine the type specified in the preamble of claim 1.
Aus
der
An den Resonanzbehälter ist bei der bekannten Anordnung ein zusätzlicher Frischlufteintritt über ein Verbindungsrohr vorgesehen, wobei an die Anschlußstutzen der Eingangsseite verlängerte Saugrohre angeschlossen sind. Durch Verschließen des Steuergliedes werden separate Strömungskanäle gebildet, die in unteren Drehzahlbereichen Verbrennungsluft über die langen Saugrohre zuführt. In oberen Drehzahlbereichen wird Luft über kurze Strömungswege zugeführt, da die Steuerglieder in die geöffnete Stellung gebracht sind, wodurch der Füllwert der einzelnen Zylinder erhöht werden kann. Die einzelnen Saugrohe an der Eingangsseite bilden dabei gemeinsam mit dem Resonanzbehälter ein Schwingrohrsystem.At the resonant tank is in the known arrangement an additional fresh air inlet over a Provided connecting pipe, wherein the connection piece of the input side extended Suction pipes are connected. By closing the control member are separate flow channels formed, the combustion air in the lower speed ranges over the feeds long suction tubes. In upper engine speed ranges, air is delivered through short flow paths supplied as the control elements in the open Position, whereby the filling value of the individual cylinders elevated can be. The individual Saugrohe on the input side form together with the resonant tank a vibration tube system.
Die längsverschieblichen Schiebemuffen zwischen den Ansaugstutzen auf der Eingangsseite und der Ausgangsseite des Resonanzbehälters können zwar den Ringspalt zwischen dem feststehenden Rohrabschnitt im Resonanzbehälter und dem gegenüberliegenden Anschlußstutzen wahlweise überbrücken. Jedoch ist aufgrund der erforderlichen Größe des Ringspaltes zur Herstellung von Strömungsverbindungen mit dem erforderlichen Querschnitt ein enormer Bauraum erforderlich. In modernen Fahrzeugen mit größeren Brennkraftmaschinen ist jedoch der zur Verfügung stehende Bauraum regelmäßig sehr begrenzt, so daß die bekannte Anordnung häufig nicht eingesetzt werden kann.The longitudinally movable Sliding sleeves between the intake manifold on the input side and Although the output side of the resonant tank, the annular gap between the fixed pipe section in the resonant tank and the opposite connecting branch optionally bridge. however is due to the required size of the annular gap for the production of flow connections With the required cross section a huge space required. In modern vehicles with larger internal combustion engines However, it is available standing space regularly very limited, so that the known arrangement often can not be used.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, die gattungsgemäße Saugrohranlage derart weiterzubilden, daß der Bauraum des Resonanzbehälters reduziert ist und die erforderlichen Strömungsquerschnitte mit dem verstellbaren Steuerglied wahlweise einstellbar sind.Of the The present invention is based on the object, the generic intake manifold develop such that the Space of the resonant tank is reduced and the required flow cross-sections with the adjustable Control member are selectively adjustable.
Diese Aufgabe wird erfindungsgemäß durch eine Saugrohranlage mit den Merkmalen des Anspruchs 1 gelöst.These The object is achieved by a Saugrohranlage solved with the features of claim 1.
Erfindungsgemäß ist für jedes Saugrohr in dem Resonanzbehälter ein einzelner runder Saugrohrabschnitt zwischen den jeweiligen Anschlußstutzen angeordnet und als Steuerglied eine konzentrisch zum Saugrohrabschnitt drehbar angeordnete Drehmuffe vorgesehen. An dem Umfang der runden Saugrohrabschnitte ist wenigstens ein Fenster vorgesehen, welches in Verschlußstellung der Drehmuffe von dem Umfang der Drehmuffe abgedeckt wird, wodurch separate Strömungskanäle durch die Saugrohrabschnitte gebildet sind. Die Drehmuffe ist an Ihrem Umfang mit pro Fenster einer Öffnung versehen, welche mit dem Fenster zusammenwirkt und durch Verdrehen der Drehmuffe eine fluidische Verbindung der Saugrohrabschnitte zum Innenraum des Resonanzbehälters schafft. Die Ausbildung eines Fensters am Umfang des Saugrohres ermöglicht einen sehr großen Durchgangsquerschnitt im Verhältnis zur Baugröße, wodurch die aus Saugrohr und Drehmuffe bestehende Baugruppe auf sehr geringem Bauraum angeordnet werden kann. Vorteilhaft ist dabei die Drehmuffe außerhalb des Saugrohrabschnitts angeordnet, wodurch zum einen der Strömungsquerschnitt im Inneren des Saugrohrs nicht beeinträchtigt und zum anderen ein einfacher Stelltrieb für die Drehmuffe angeordnet werden kann.According to the invention is for each Suction tube in the resonant tank a single round Saugrohrabschnitt between the respective connecting piece arranged and as a control member concentric with the Saugrohrabschnitt rotatably arranged rotary sleeve provided. At the circumference of the round Saugrohrabschnitte At least one window is provided which in the closed position the rotary sleeve is covered by the circumference of the rotary sleeve, thereby through separate flow channels the Saugrohrabschnitte are formed. The rotary sleeve is on your Perimeter with per window of an opening provided, which cooperates with the window and by twisting the rotary sleeve a fluidic connection of the Saugrohrabschnitte to the interior of the resonant tank creates. The formation of a window on the circumference of the suction tube allows a very big one Passage cross-section in proportion to the size, thereby the intake manifold and rotary sleeve assembly on very low Installation space can be arranged. The advantage here is the rotary sleeve outside arranged on the Saugrohrabschnitts, whereby on the one hand the flow cross-section inside the suction tube is not affected and on the other simple actuator for the rotary sleeve can be arranged.
In bevorzugter Ausgestaltung der Erfindung ist als Stelltrieb eine Stellstange vorgesehen, welche bei parallel in einer Ebene liegenden Saugrohrabschnitten quer zu den Saugrohrabschnitten angeordnet wird. Die Stellstange trägt pro Drehmuffe einen Betätigungsstift, der an einer an der jeweiligen Drehmuffe ausgebildeten Gleitschiene geführt ist, wodurch eine formschlüssige und sichere Betätigung durch Längsverschiebung der Stellstange möglich ist. Die Stellstange kann dabei aus dem Resonanzbehälter herausgeführt werden und dort von einem Stellantrieb betätigt werden.In preferred embodiment of the invention is as an actuator Actuator provided, which in parallel lying in a plane Saugrohrabschnitten is arranged transversely to the Saugrohrabschnitten. The control rod carries one actuating pin per rotary sleeve, at a trained on the respective rotary bushing slide guided is, whereby a form-fitting and safe operation by longitudinal displacement the control rod is possible. The control rod can be led out of the resonant tank and there be actuated by an actuator.
Große Strömungsquerschnitte bei geringen Stellwegen der Drehmuffe können bereitgestellt werden, wenn in dem Saugrohrabschnitt zwei diametral gegenüberliegende Fenster vorgesehen sind. Eine einfache Montage der Drehmuffe an dem Saugrohrabschnitt ergibt sich, wenn die Drehmuffe aus zwei miteinander verbundenen Halbschalen zusammengesetzt ist, welche um das Saugrohr gelegt werden. Zweckmäßig ist dabei der Saugrohrabschnitt durch ein in den Resonanzbehälter einsetzbares Rohrbauteil gebildet, welches mit der Drehmuffe vormontiert werden kann.Large flow cross sections with small travel ranges of the rotary sleeve can be provided if two diametrically opposite windows are provided in the suction pipe section. A simple installation of the rotary sleeve on the Saugrohrabschnitt results when the rotary sleeve is composed of two interconnected half-shells, which are placed around the suction pipe. Expediently, the suction pipe section is formed by a tube component which can be inserted into the resonance container and which can be preassembled with the rotary sleeve.
Der erforderliche Bauraum der Saugrohranlage kann reduziert werden, wenn der kompakte Resonanzbehälter als Luftsammler in die Saugrohranlage integriert wird.Of the required installation space of the intake manifold can be reduced when the compact resonant tank is integrated as an air collector in the intake manifold.
