Abstract
Description
Die Erfindung betrifft ein Luftansaugrohr für eine Brenn kraftmaschine nach dem Oberbegriff des Anspruchs 1.The invention relates to an air intake pipe for a burner Motor machine according to the preamble of claim 1.
Derartige Luftansaugrohre weisen zur Erhöhung der Zylinder füllung bzw. des Motordrehmoments erhebliche Schwinglängen auf, und es sind bereits eine Reihe von Vorschlägen be kannt, wie diese mit geringstem Bauraum realisiert werden können (DE-GM 92 17 249).Such air intake pipes have to increase the cylinders filling or the engine torque considerable oscillation lengths on, and there are already a number of suggestions knows how these can be realized with the smallest possible installation space can (DE-GM 92 17 249).
Aus dem DE-GM 89 14 049 ist bereits bekannt, ein Luftan saugrohr aus mehreren Bauteilen herzustellen, die als Guß teile ausgeführt und zusammengeschraubt sind.From DE-GM 89 14 049 an Luftan is already known Manufacture intake manifold from several components that are cast parts executed and screwed together.
Diese Lösung hat jedoch den Nachteil, daß die Bauteilkon taktflächen sehr genau hergestellt werden müssen, um Dich tigkeit zu erlangen, und wegen der Teilevielzahl besteht ein erhöhter Montageaufwand.However, this solution has the disadvantage that the component con tactical areas must be made very precisely to you activity and because of the large number of parts increased assembly effort.
Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, ein gattungsgemäßes Luftansaugrohr derart zu gestalten, daß geringer Bauraum, eine geringe Bauteilanzahl sowie gering ste mechanische Bearbeitung und Montageaufwand erreichbar sind.Proceeding from this, the object of the invention is to design a generic air intake pipe such that small space, a small number of components and small mechanical processing and assembly effort are.
Diese Aufgabe ist durch die im Kennzeichen des Anspruchs 1 angegebenen Merkmale gelöst, weitere Merkmale vorteilhafter Weiterbildungen sind in den Unteransprüchen angegeben.This object is achieved in the characterizing part of claim 1 specified features solved, other features more advantageous Further developments are specified in the subclaims.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird nachfolgend mit Angabe erreichbarer Vorteile beschrieben.An embodiment of the invention is in the drawing is shown and is more accessible below with details Advantages described.
Diese Zeichnung zeigt:This drawing shows:
Fig. 1 ein erfindungsgemäßes Luftansaugrohr, Fig. 1 shows an inventive air intake pipe,
Fig. 2 einen Querschnitt aus Fig. 1, Fig. 2 shows a cross section of Fig. 1,
Fig. 3 einen Längsschnitt aus Fig. 1. Fig. 3 a longitudinal section in FIG. 1.
Fig. 1 zeigt ein Luftansaugrohr 1 für eine Brennkraftma schine, das mit einer Flanschleiste 2 am Zylinderkopf derselben angeschraubt werden kann. Fig. 1 shows an air intake pipe 1 for an internal combustion engine, which can be screwed to the cylinder head of the same with a flange 2 .
Das Luftansaugrohr 1 besteht aus der Flanschleiste 2 und einem Sammelrohr 3, die beide durch Seitenwände 4, einen Rahmen bildend verbunden und als Gußstück hergestellt sind.The air intake pipe 1 consists of the flange 2 and a manifold 3 , both of which are connected by side walls 4 , forming a frame and are produced as a casting.
Zwischen der Flanschleiste 2 und dem Sammelrohr 3 sind, wie in Fig. 2 dargestellt, Rohrkrümmer 5 in entsprechend ausge formte Aufnahmebohrungen 6, 7 eingespannt, die Einzelkanäle bilden, die ausgehend vom Sammelrohr 3 zu den einzelnen Zy lindern der Brennkraftmaschine führen. Das Sammelrohr 3 weist an einer Stirnwand 8 einen integrierten Drosselklap penstutzen 9 auf, wobei die entgegengesetzte Stirnwand 10 von einem Deckel 11 gebildet ist. Auf diese Art läßt sich ein im Drosselklappenstutzen 9 bestehender Drosselabschnitt 12 ausformen, wie aus Fig. 3 ersichtlich, indem beiderseits des Drosselabschnitts 12 Formzüge ausgezogen werden können.Between the flange 2 and the manifold 3 , as shown in Fig. 2, pipe elbows 5 are clamped in correspondingly shaped receiving bores 6 , 7 , which form individual channels that alleviate starting from the manifold 3 to the individual Zy the engine. The header tube 3 has an integrated Drosselklap penstutzen 9 on an end wall 8 , the opposite end wall 10 being formed by a cover 11 . In this way, an existing throttle section 12 in the throttle valve neck 9 can be formed, as can be seen in FIG. 3, by pulling out molds 12 on both sides of the throttle section.
Die Rohrkrümmer 5 werden, wie in Fig. 2 dargestellt ist, unter Zwischenlage einer elastischen Dichtung 13 einge spannt und durch umgeformte Sammelrohr- bzw. Flanschlei stenwände 14 bzw. 15 gehalten.The elbows 5 are, as shown in Fig. 2, clamped with the interposition of an elastic seal 13 and are held by reshaped manifold or flange guide walls 14 and 15 respectively.
Die Montage der Rohrkrümmer 5 wird erleichtert, wenn die Rohrkrümmer 5 einen Krümmungsbogenabschnitt mit einem Win kel α von etwa 180° aufweisen.The assembly of the pipe elbow 5 is facilitated if the pipe elbow 5 have a curved section with a win angle α of about 180 °.
In die Flanschleiste 2 können elektrische Einspritzventile eingesetzt werden, wobei die hierfür vorgesehenen Aufnahme bohrungen in Einzelkanäle 16 einmünden, die in der Flansch leiste 2 in Weiterführung der Rohrkrümmerkanäle bestehen. Die elastische Dichtung 13 ist vorteilhafterweise auf der Einströmseite als Einlauflufttrichter 17 ausgebildet.In the flange strip 2 , electrical injection valves can be used, the receptacles provided for this purpose opening into individual channels 16 , which consist in the flange strip 2 in continuation of the pipe elbow channels. The elastic seal 13 is advantageously designed as an inlet air funnel 17 on the inflow side.
Mit dem erfindungsgemäßen Luftansaugrohr 1 liegt eine sehr steife Rahmenkonstruktion vor, die als Gußteil in Formma schinen und mit weniger mechanischer Bearbeitung herge stellt werden kann. With the air intake pipe 1 according to the invention, there is a very rigid frame construction which can be machined as a casting in Formma and can be produced with less mechanical processing.
Die als gelängte Rohrkrümmer 5 ausgeführten Einzelkanäle sind sehr dünnwandig und weisen eine sehr glatte Oberfläche auf. Damit liegt eine Gewichtsreduzierung gegenüber gegos senen Rohren vor und die angesaugte Luft strömt mit vermin derter Reibung in die Brennzylinder ein, womit eine bessere Füllung erreicht wird. Die durch umgeformte Wandungen 14, 15 erreichte Befestigung der Rohrkrümmer 5 ist gegenüber Verschraubung billiger.The individual channels 5, which are designed as elongated elbows, are very thin-walled and have a very smooth surface. This results in a weight reduction compared to cast pipes and the sucked-in air flows into the combustion cylinder with reduced friction, thus achieving a better filling. The fastening of the pipe elbow 5 achieved by deformed walls 14 , 15 is cheaper than screwing.
Die integrierte Anordnung des Drosselklappenstutzens 9 so wie der elektrischen Einspritzventile läßt ein kompaktes Einbauteil entstehen, das eine integrierte Funktionsüber prüfung der einzelnen Funktionsgruppen ermöglicht. Hierdurch werden Qualität erhöht und Kosten vermieden.The integrated arrangement of the throttle valve connector 9 as well as the electric injection valves allows a compact installation part to be created which enables an integrated function check of the individual function groups. This increases quality and avoids costs.
