Abstract

To the individual engine cylinders lead pipe sections (2), extending individually, or in a bundle over the cylinder head (3), or its cover hood (4). The pipe sections are interconnected by a ribbed wall (5) forming, together with the pipe sections a cylinder head and its hood cover (6). Pref. the hood cover, or the ribbed wall, ends in a skirt edge (7). The ribbed wall may have apertures (8) for elements of a fuel injection system, closed by sound absorbing lids (9), lined with foamed plastics. Typically the cylinder head hood and intake manifold (2) form an integral unit.

Description

Die Erfindung betrifft ein Luftansaugrohr für Brennkraftmaschinen nach dem Oberbe­ griff des Patentanspruchs 1. Ein derartiges Luftansaugrohr ist in der DE-A1- 42 40 114 offenbart mit den Merkmalen, daß zu einzelnen Zylindern der Brenn­ kraftmaschine führende Rohrabschnitte in einer parallel zur Längsachse der Brenn­ kraftmaschine gedachten Fläche liegen, d. h., die Rohrabschnitte ragen über den Zylinderkopf bzw. dessen Abschlußdeckel.The invention relates to an air intake pipe for internal combustion engines according to the Oberbe handle of claim 1. Such an air intake pipe is in DE-A1- 42 40 114 discloses with the features that the combustion of individual cylinders engine-leading pipe sections in a parallel to the longitudinal axis of the combustion machine imaginary area, d. that is, the pipe sections protrude above the Cylinder head or its end cover.

Aus der DE-A1-42 12 255 ist eine Anordnung einer Kraftstoff-Einspritzvorrichtung am Gehäuse einer Brennkraftmaschine bekannt, bei der ein Bauelement der Kraft­ stoff-Einspritzvorrichtung an der Zylinderkopfhaube angeordnet ist, bevorzugt soll ein Pumpelement mit einem Magnetventil an der Zylinderkopfhaube angeordnet sein.DE-A1-42 12 255 describes an arrangement of a fuel injection device known on the housing of an internal combustion engine, in which a component of the force Material injection device is arranged on the cylinder head cover, preferably one Pump element can be arranged with a solenoid valve on the cylinder head cover.

Eine Kombination des Luftansaugrohrs mit der Anordnung des Bauelements, das auswechselbar sein muß, an der Zylinderkopfhaube hätte zur Folge, daß das/die Bauelement(e) zwischen den Rohrabschnitten angeordnet ist/sind.A combination of the air intake pipe with the arrangement of the component that replaceable, on the cylinder head cover would result in that Component (s) is / are arranged between the pipe sections.

Die so angeordneten Bauelemente und die weiteren, am Zylinderkopf selbst an­ geordneten Bauelemente bilden eine erhebliche Lärmquelle und müssen durch Dämp­ fungs- und Abschirmmaßnahmen isoliert werden, die teuer sind und Bauraum- und Teileaufwand erfordern.The components arranged in this way and the others on the cylinder head itself Ordered components form a significant source of noise and must be damped Isolation and shielding measures are isolated, which are expensive and space and Require parts.

Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, ein gattungsgemäßes Luftansaugrohr derart zu gestalten, daß in bezug auf die Kraftstoff-Einspritzvor­ richtung eine Lärmquellenisolierung erreicht wird. Proceeding from this, the object of the invention is to create a generic one To design the air intake pipe so that in relation to the fuel injection direction noise source insulation is achieved.  

Diese Aufgabe ist durch die im Kennzeichen des Patentanspruchs 1 angegebenen Maßnahmen gelöst. Vorteilhafte Weiterbildungen sind in den Unteransprüchen angegeben.This object is indicated by the characterizing part of claim 1 Measures solved. Advantageous further developments are in the subclaims specified.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird nachfolgend beschrieben.An embodiment of the invention is shown in the drawing and will described below.

Diese zeigt;
Eine Ansicht einer Brennkraftmaschine mit einem Luftansaugrohr 1 mit zu den einzelnen Zylindern der Brennkraftmaschine führenden Rohrabschnitten 2, die sich einzeln oder gebündelt über den Zylinderkopf 3 bzw. die Zylinderkopfhaube 4 erstrec­ ken. Die Rohrabschnitte 2 sind untereinander mit einer Rippenwandung 5 verbunden, die in Verbindung mit den Rohrabschnitten 2 eine Zylinderkopf-/Zylinderkopfhauben­ abdeckung 6 ergibt. Vorteilhafterweise endet die Rippenwandung 5 in einer Schür­ zenumrandung 7. Die Brennkraftmaschine weist eine nicht extra dargestellte Kraft­ stoff-Einspritzvorrichtung auf, deren Bauelemente unterhalb der Abdeckung 6 an dem Zylinderkopf 3 bzw. der Zylinderkopfhaube 4 angeordnet sind. Es ist nun vorgesehen, daß diese ohne Demontage des Luftansaugrohrs 1 ausgewechselt werden können. Hierfür weist das Luftansaugrohr 1 in der Rippenwandung 5 bzw. der Abdeckung 6 Durchbrüche 8 auf. Diese können, wie dargestellt, durch Deckel 9 verschlossen werden, die schallschluckend ausgebildet sind, z. B. durch eine Auskleidung 10 mit Schaumstoff. Es kann vorgesehen sein, daß die Zylinderkopfhaube 4 einstückig mit dem Luftansaugrohr 1 ausgebildet ist. Hierbei würde eine Schwingungsentkopplung über ein als Dichtung wirkendes Elastomerbauteil erfolgen, das zwischen Zylin­ derkopf 3 und Luftansaugrohr 1 bzw. Zylinderkopfhaube 4 angeordnet ist (nicht dargestellt).This shows;
A view of an internal combustion engine with an air intake pipe 1 with pipe sections 2 leading to the individual cylinders of the internal combustion engine, which are individually or bundled via the cylinder head 3 or the cylinder head cover 4, respectively. The pipe sections 2 are connected to one another with a rib wall 5 , which in connection with the pipe sections 2 gives a cylinder head / cylinder head cover 6 . Advantageously, the rib wall 5 ends in a border zen 7th The internal combustion engine has a fuel injector, not shown, the components of which are arranged below the cover 6 on the cylinder head 3 or the cylinder head cover 4 . It is now provided that these can be replaced without dismantling the air intake pipe 1 . For this purpose, the air intake pipe 1 has openings 8 in the rib wall 5 or the cover 6 . These can, as shown, be closed by cover 9 , which are sound-absorbing, for. B. by a lining 10 with foam. It can be provided that the cylinder head cover 4 is formed in one piece with the air intake pipe 1 . Here, a vibration decoupling would take place via an elastomer component acting as a seal, which is arranged between the cylinder head 3 and the air intake pipe 1 or cylinder head cover 4 (not shown).

Insgesamt ergibt die Ausführung des Luftansaugrohrs 1 nach der Erfindung eine leicht herzustellende und wirksame Schallisolierung der Bauelemente der Kraftstoff- Einspritzvorrichtung, womit eine damit ausgestattete Brennkraftmaschine für den Einsatz in einem Kraftfahrzeug geeignet ist.Overall, the design of the air intake pipe 1 according to the invention results in easy-to-manufacture and effective sound insulation of the components of the fuel injection device, so that an internal combustion engine equipped therewith is suitable for use in a motor vehicle.
