Definitions

  • the invention relates to an exhaust pipe according to the preamble of claim 1.
  • a double-walled exhaust pipe which has an insulating material in the annular space between the individual pipes and the encapsulation. Furthermore, an exhaust pipe is known from DE 40 21 563 A1, which has a subdivision. Furthermore, an exhaust pipe is known from US-PS 40 22 019, in which the individual pipes open into a pipe socket, which is designed as a pipe funnel.
  • the object of the invention is to provide an exhaust pipe for an internal combustion engine which can be connected in a simple manner to a catalytic converter and which ensures thermal insulation.
  • the main advantages achieved with the invention are that the individual pipelines branching off the engine - consisting of inner and outer pipes - are combined to form a connection element for connection to an exhaust gas catalytic converter.
  • This is done in a separately manufactured pipe socket, which serves as an adapter for connection to the catalytic converter.
  • This is structurally simple to manufacture and creates a possibility of connecting the four or more individual pipelines with a connecting line of the exhaust gas catalytic converter.
  • the individual pipelines continued in the pipe socket are pressed together with the catalyst up to the fastening flange in such a way that four tubular elements with a triangular cross section are formed which are connected to one another, for example by welding. These are fixed in a hole in the mounting flange by welding.
  • the pipe pieces in the pipe socket are plugged onto or into the individual pipes of the exhaust pipe and have a sliding or loose fit, so that no tension can occur in the high prevailing temperatures in the exhaust pipe.
  • the pipe socket has a housing capsule, in which an air space is formed between the pipe pieces, which is continued in the individual pipes by outer pipes, so that there is a continuous air space and thus a continuous heat insulation from the connection to the engine to the catalytic converter.
  • the housing capsule is connected to the respective individual pipelines, for example, by means of molded rings which are pushed onto the outer pipes of the individual pipelines and which can be welded to the outer pipes and to the housing capsule.
  • the air spaces pass from the individual pipelines into the housing capsule in the area of the molded rings.
  • the pipe socket is deformed by pressing its pipe pieces into a tubular cross section in one or more operations.
  • a connection to the housing capsule is made in the fastening flange by means of a weld, the shaped ring being designed in a Z-shape and establishing a connection to the outer pipe of the individual pipelines and permitting thermal expansion.
  • an exhaust gas line 1 for an internal combustion engine comprises four individual pipelines 2 to 5, which are connected on the engine side via a screw-on flange A and on an exhaust gas catalytic converter (not shown) via an end-side fastening flange 6a.
  • the individual pipelines 2 to 5, coming from the engine, are spatially brought together in front of a pipe socket 6 and connected to the latter.
  • the pipe socket 6 comprises, according to the number of individual pipes 2 to 5, four pipe pieces 7 to 10, which are combined to form a single tubular connecting element R, consisting of four pipe elements 7a to 10a with a triangular cross section, as shown in FIG. 6.
  • the individual pipelines 2 to 5 and the pipe socket 6 each have capsules 11, 12.
  • these consist of outer tubes 13 which surround the inner tubes 14 with an air space 15.
  • the pipe socket 6 has a surrounding housing 12, which encloses all pipe sections 7 to 10 and the compressed pipe elements 7a to 10a with an air space 16.
  • the pipe sections 7 to 10 in the pipe socket 6 are arranged for connection to the exhaust pipe 1 on the inner pipes 14 of the individual pipes 2 to 5 with a sliding or loose fit.
  • the outer tubes 13 are connected to the housing capsule 12 of the pipe socket 6 via Z-shaped shaped rings 20, the legs of which are welded to the housing capsule 12 and to the outer tube 11.
  • the air spaces 15 between the inner and outer tubes 14 and 13 and the air space 16 between the tubes 7 to 10 and the housing capsule 12 have a continuous connection 21 in the area of the plane X-X of the molded rings 20.
  • the pipe sections 7a to 10a having the triangular cross sections are fastened in the fastening flange 6a in a bore which represents the mouth opening 22, for example by welding.
