Definitions
- the invention relates to a gas line system according to the preamble of Claim 1.
- the invention is based, in general a gas line system in the task To create cases where these and similar problems arise, and this Train the gas pipeline system so that it does not affect the tightness of the Systems based on rigid connections of the different parts or areas of the Difficulties based on the gas line system are avoided.
- the invention thus provides for a subdivision of the gas line system into at least two Direction of flow of gases in front of successive parts, forming gaps merge into each other without contact.
- This gap formation has a disadvantage in itself because it can be described as a specific leak in the gas pipe system.
- the second gas line is in the flow direction as Diffuser panel designed by converting speed energy into Pressure energy ensures gas intake from the environment through the gap.
- this gap ensures that a direct movement or Vibration transmission via the gas line system is prevented, and on the other hand it enables relative movements of the components of the gas pipe system to each other, so that a suspension, for example, on vehicle parts that are in operation of the vehicle can also perform somewhat larger relative movements to each other.
- the gas line system contains the first gas line 1 and the second gas line 2, their with respect to the gas flow, here an exhaust gas flow 3, a front end region forms larger flow cross-section F1 than the first gas line 1, so that this under Maintaining a gap 4 protrudes into the first area 5 of the second gas line 2. While this first line region 5 has a constant cross section, the one increases Flow cross section of the adjoining area 6 of the second gas line 2 from a value F2, which is identical to the value F1, continuously up to one Maximum value F3.
- the area 5 has a length I1
- the area 6 has a length I2.
- the flow cross section of the gap 4 amount to at most about 80% of the flow cross section of the first region 5.
- the maximum flow cross section F3 of the outlet area 6 should be smaller than the flow cross-section in which a disruptive flow separation would occur. As has been shown, it is advantageous if the maximum Flow cross section F3 about 100 mm after area 5 twice Flow cross section F2 of the inlet area 5 corresponds. Basically you can say that the smaller the, the better the function of the diffuser screen Flow cross-section of the gap; this contactless decoupling through the gap understandably, however, must not be lost.
- gas lines 1 and 2 are not must necessarily have round cross sections, so the gap 4 also one of the shape of the annular disc can have a different shape.

Abstract
Description
Claims (4)
- Gasleitungssystem, insbesondere Abgasleitungssystem für eine ein Fahrzeug antreibende Brennkraftmaschine, gekennzeichnet durch zwei in Gasströmungsrichtung (3) im wesentlichen aufeinanderfolgende Gasleitungen (1, 2), von denen die der Gasquelle nähere erste Gasleitung (1) mit einem Endbereich unter Wahrung eines Spalts (4) berührungslos in den eine größere lichte Weite aufweisenden zugekehrten Endbereich der zweiten Gasleitung (2) hineinragt, die als Diffusorblende mit in Gasströmungsrichtung (3) kontinuierlich zunehmendem Strömungsquerschnitt ausgebildet ist.
- Gasleitungssystem nach Anspruch 1, dadurch gekennzeichnet, daß die zweite Gasleitung (2) einen der ersten Gasleitung (1) zugekehrten Einlaßbereich (5) mit über seine Länge konstantem Strömungsquerschnitt (F2) und anschließend einen Auslaßbereich (6) mit dem kontinuierlich zunehmenden Strömungsquerschnitt aufweist, wobei der von dem Spalt (4) gebildete Strömungsquerschnitt höchstens etwa 80 % des Strömungsquerschnitts (F2) des Einlaßbereichs (5) beträgt, während der maximale Strömungsquerschnitt (F3) des Auslaßbereichs (6) kleiner als ein Strömungsquerschnitt bemessen ist, bei dem eine störende Strömungsablösung auftritt.
- Gasleitungssystem nach Anspruch 2, dadurch gekennzeichnet, daß der maximale Strömungsquerschnitt (F3) etwa 100 mm hinter dem Einlaßbereich (5) dem Doppelten des Strömungsquerschnitts (F2) des Einlaßbereichs (5) entspricht.
- Gasleitungssystem nach einem der Ansprüche 1 bis 3, dadurch gekennzeichnet, daß es den Endbereich einer Kraftfahrzeug-Abgasanlage bildet.
