Definitions
- the invention relates to an exhaust pipe according to the preamble of Claim 1.
- the object of the invention is to provide an exhaust pipe for an internal combustion engine create that is easily connected to a catalyst and a Thermal insulation guaranteed.
- the pipe sections in the pipe socket are on or in the individual pipes of the exhaust pipe inserted and have a sliding or loose seat, which means at high prevailing temperatures in the exhaust pipe no tension can.
- the pipe socket has a housing capsule, in which between the Pipe pieces an air space is formed by the individual pipes Outer tubes is continued, so that from the connection to the engine a continuous air space directly to the catalytic converter and thus one continuous thermal insulation results.
- a connection between the housing capsule and the individual pipelines takes place, for example, by pushing onto the outer pipes of the individual pipes Form rings, which with the outer tubes and with the housing capsule are weldable.
- a passage of the air spaces from the individual pipelines into the housing capsule takes place in the area of the form rings.
- the pipe socket becomes one by pressing its pipe sections tubular cross-section deformed in one or more operations.
- a connection to the housing capsule is made in the mounting flange a weld, the form ring is Z-shaped and a Connects to the outer pipe of the individual pipes and a Allows thermal expansion.
- An exhaust pipe 1 for an internal combustion engine comprises a four-cylinder one Internal combustion engine four individual pipes 2 to 5, the one on the engine side Screw-on flange A and on an exhaust gas catalytic converter (not shown) via a end mounting flange 6a are connected.
- the individual pipes 2 to 5 are spatially in front of one coming from the engine Pipe socket 6 merged and connected to this.
- the pipe socket 6 includes 2 to 5 four pieces of pipe according to the number of individual pipes 7 to 10, consisting of a single tubular connecting element R four tubular elements 7a to 10a with a triangular cross section, are summarized, as shown in FIG. 6.
- the individual pipes 2 to 5 and the pipe socket 6 each have capsules 11, 12 on.
- these consist of outer pipes 13, which surround the inner tubes 14 with an air space 15.
- the pipe socket 6 has, as a capsule, a surrounding housing 12 which contains all the pipe sections 7 to 10 and the compressed pipe elements 7a to 10a with an air space 16 encloses.
- the pipe sections 7 to 10 in the pipe socket 6 are for connecting to the Exhaust pipe 1 on the inner pipes 14 of the individual pipes 2 to 5 with a Sliding or loose seat arranged.
- a connection of the outer tubes 13 to the housing capsule 12 of the pipe socket 6 takes place via Z-shaped form rings 20, the legs of which with the housing capsule 12 and are welded 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 in Area of the plane X-X of the shaped rings 20 has a continuous connection 21.
- the pipe sections 7a to 10a having the triangular cross sections are in the mounting flange 6a in a bore which defines the mouth opening 22 represents, for example, fixed by a weld.
