- soot particles can be filtered out.
- Such particle filters must be regenerated continuously or discontinuously in order to prevent the
- embedded particles increase the caused by the particulate filter exhaust back pressure in an inadmissible manner. This is done by an afterburning or post-oxidation of the soot particles, for which a correspondingly high (ignition) temperature is required.

- the tube tapers again before it widens again in a third (end) section.
- a plurality of radially arranged and spirally arranged wings are arranged. Through these wings and in combination with the diameter profile of the various sections of the guide tube acceleration of the guide tube flowing through the exhaust gas is to be achieved. This is intended to remove the exhaust gas in an improved manner from the combustion chambers of the internal combustion engine to which the exhaust gas line is connected, which in turn has a positive effect on the operating behavior of the engine
- the device has a further tube which surrounds the third portion of the guide tube on the outside, said tube having an open to both ends annular gap with the outside of the
- the invention had the object of specifying an exhaust pipe for the exhaust system of an internal combustion engine, which has an air connection, which serves to mix air in exhaust gas flowing in the exhaust pipe, wherein by means of the exhaust pipe in a structurally simple and thus cost-effective way possible good mixing should be achieved.
- An exhaust pipe for the exhaust gas line of an internal combustion engine which has an inlet opening for an air connection, is according to the invention by an inner pipe section
- Mixture of the air with the exhaust gas may be of particular importance when the exhaust gas branch branches into at least and in particular exactly two strands in a relatively short distance behind the exhaust pipe, wherein (in each case) a particle filter is integrated into one or more or all of the strands , This can make a training unequal

- an exhaust pipe according to the invention can be provided that within the inner pipe section at least one flow guide for generating a swirl flow of the exhaust gas is arranged.
- Such an exhaust pipe according to the invention can be designed to be producible in an advantageous manner if, as is preferably provided, the flow guide element is designed in the form of a (plastically and thus permanently) deformed pipe jacket section.
- the tube jacket section can particularly preferably have a dirty shape, with a forming edge of the flow guide element being introduced from one into the tube jacket
- Inner tube section is aligned, spiraling with respect to the longitudinal axis of the
- Inner pipe section runs.
- the longitudinal opening terminates at an end edge of the inner pipe section, so that the
- Forming edge also extends to this end edge. In this way, it is possible to dispense with the introduction of a second longitudinal opening that extends in the circumferential direction and merges into the first longitudinal opening.
- the Longitudinal opening (s) may / may preferably be introduced later in the pipe jacket in the form of separating cuts.
- the production of such a flow guide is therefore relatively simple. For this purpose, only the longitudinal opening (s) must / must be introduced into the inner pipe section and then the flow guide be formed by a corresponding triangular pipe casing section is bent along the Umformkante.
- the invention also relates to a corresponding method for producing such an exhaust pipe according to the invention.
- Flow guide can be provided that the inner pipe section adjacent to a preferably downstream (with respect to the intended flow direction of the exhaust gas) side of the flow guide a passage or
- Tube casing opening forms.

- a particularly advantageous mixing between the air and the exhaust gas can be realized.
- An internal combustion engine comprises at least one internal combustion engine and an exhaust system for discharging exhaust gas from the internal combustion engine, wherein an air connection for introducing air into the exhaust system is also integrated into the exhaust system.
- the exhaust gas system further comprises at least one exhaust pipe according to the invention.
- a motor vehicle according to the invention comprises at least one inventive
- the motor vehicle may in particular be a wheel-based motor vehicle, preferably a car or truck.
- the internal combustion engine of the internal combustion engine can be provided in particular for (direct or indirect) provision of the drive power for the motor vehicle.
- the exhaust pipe of an internal combustion engine according to the invention is used for the admixture of air in exhaust gas routed through the exhaust line or through the exhaust pipe as required, this air preferably for the regeneration of a in the exhaust line downstream of the air connection integrated particle filter is used.
- regeneration of the particulate filter using the air admixed with the exhaust gas may be necessary or expedient in particular because an exhaust gas catalyst, in particular a 3-way catalytic converter, is integrated into the exhaust gas line upstream of the air connection, so that a relatively large distance of the particulate filter results from the internal combustion engine, which in turn means that the exhaust gas already has a relatively low temperature when reaching the particulate filter, in particular because of the previous flow through the catalytic converter.
- Such an arrangement of such exhaust aftertreatment devices may be useful, in particular, in a spark-ignited internal combustion engine, in particular in an internal combustion engine (Otto engine) operated according to the Otto principle.
- the particle filter is arranged below a lower floor of the motor vehicle.
- Internal combustion engine receiving engine compartment extends in the direction of the rear of the motor vehicle.
- the provided for admixture in the exhaust air in particular a

- Connecting pipe integrated conveying device which is used to convey air from the
- Fresh gas line is provided to the air connection of the exhaust pipe to supply filtered air.
- Components are thus to be understood that they are present at least once and may be present more than once.
- FIG. 1 shows a simplified representation of an inventive motor vehicle.
- 2 shows a schematic representation of an internal combustion engine according to the invention.
- FIG. 3 shows a partial longitudinal section through an inventive exhaust pipe.
- Fig. 1 shows an inventive motor vehicle with an inventive
- the internal combustion engine 10 may comprise an internal combustion engine 12, in particular a gasoline engine, which forms a plurality of cylinders 14.
- the cylinders 14 together with reciprocating pistons and a cylinder head (not shown) define combustion chambers in which fresh gas (mainly air) is combusted together with fuel, thereby cyclically moving the pistons up and down. This movement of the piston is transmitted in a known manner to a crankshaft, not shown, and thus driven in rotation.
- the fresh gas is supplied to the internal combustion engine 12 via a fresh gas line and sucked to it via an intake port 16 from the environment, cleaned in an air filter 18 and then into a compressor 20, which is part of an exhaust gas turbocharger.
- the fresh gas is compressed by means of the compressor 20, then cooled in a charge air cooler 22 and, optionally controlled by means of a throttle valve 24, fed to the combustion chambers.
- the drive of the compressor 20 is effected by means of a turbine 26, which is integrated in an exhaust line of the internal combustion engine and also part of the exhaust gas turbocharger.
- Exhaust gas which is produced during the combustion of the fuel-fresh gas mixture in the combustion chambers of the internal combustion engine 10, is discharged via the exhaust line from the internal combustion engine 12 and flows through first an exhaust gas catalyst 28 in the form of a 3-way catalyst, then the turbine 26, Subsequently, an inventive exhaust pipe 30 and then a particulate filter 32, before the exhaust gas after a flow through a
- Silencer (not shown) is released into the environment. Due to the arrangement of the exhaust gas catalytic converter 28 close to the engine and due to the arrangement located downstream of the turbine 26, it may be necessary for the sake of the installation space, which is only limited in an engine compartment of the motor vehicle, to place the particulate filter 32 underneath a subfloor 80 of the motor vehicle (see FIG. to arrange.
- the flow through the turbine 26 leads in a known manner to a rotating drive of a turbine impeller, which in turn is non-rotatably connected via a shaft 34 to a compressor impeller of the compressor 20.
- the rotating drive of the turbine runner is thus transmitted to the compressor wheel.
- the turbine 26 can be bypassed in a known manner by means of a so-called wastegate 36.
- a turbine with variable turbine geometry can also be used.
- VGT turbine with variable turbine geometry
- the particle filter 32 serves to filter out particles and in particular soot particles from the exhaust gas. This may cause the particulate filter 32 to become clogged during operation, necessitating regeneration of the particulate filter 32 to prevent the exhaust back pressure caused by the particulate filter 32 from becoming unduly high.
- internal engine measures are implemented during operation of the internal combustion engine 12, on the one hand to set relatively high exhaust gas temperatures and on the other hand to increase the proportion of unburned hydrocarbons within the exhaust gas.
- the oxygen provided for this purpose is supplied to the exhaust gas as a component of air via an air connection 42, which is integrated into an exhaust pipe 30 according to the invention.
- the air via a connecting line 38, the downstream of the air filter 18 from the
- Exhaust pipe 30 opens, led. The conveying of this air is assisted or effected by means of a conveying device 44.
- the exhaust pipe 30 represents a relatively short distance upstream of the particulate filter 32 disposed portion of the exhaust line.
- Such an exhaust pipe 30 may have the structural configuration shown in FIG. 3.
- This exhaust pipe 30 according to FIG. 3 comprises a first pipe section 46, which has constant inner and outer diameter over the longitudinal extent, and a second pipe section 48, which also over the longitudinal extent constant inside and
- the two pipe sections 46, 48 are curved while running educated.
- An end portion 52 of the first tube piece 46 is inserted in the direction along its longitudinal axis 50 and in coaxial arrangement in an end portion 54 of the second tube piece 48. This end portion 52 of the first pipe section 46 provides a
- Outside pipe section 58 of the exhaust pipe 30 is formed between the two end portions 52, 54 and pipe sections 56, 58, an annular channel 60, since the
- Inner diameter of the second pipe section 48 is greater than the outer diameter of the first pipe section 46 to a defined extent.
- This annular channel 60 is formed at the upstream end with respect to the (flow) direction provided for the flow of the exhaust gas 62 and thereby closed to the environment.
- Pipe section 48 forms a radially inwardly extending end edge 66, which contacts the outside of the outside of the first pipe section 46 and sealingly connected thereto, for example, soldered, welded or glued.
- the annular channel 60 is open, whereby air 68, which is supplied to the exhaust pipe 30 via the air connection 42 connected to the inlet port 40, at first fully within the Distribute annular channel 60 and from this with a direction basically the flow direction of the exhaust gas 62 corresponding flow direction in the downstream of the annular channel 60 section of the second pipe section 48 can flow where the air 68 with the exhaust gas 62, from the first pipe section 46 in the second Pipe 48 is overflowed, mix and 70 can be supplied to the particulate filter 32 as an exhaust gas-air mixture.
- the inner pipe section 56 forms at the downstream end with respect to the flow direction of the exhaust gas 62 a plurality of flow guide elements 72 in the form of obliquely with respect to the longitudinal axis 50 of the exhaust pipe 30 aligned baffles. These flow guide 74 cause a spin of this through or
- the flow guide elements 72 are arranged distributed in identical alignment and in a uniform pitch over the circumference of the inner pipe section 56. These were produced by longitudinally extending longitudinally spaced openings 74 with a uniform pitch Length in the form of cuts in the formed by the end portion 52 of the first pipe section 46 pipe jacket have been introduced. Then, in each case a triangular section of this tubular jacket was bent inward along a forming edge 76 running obliquely or helically about the longitudinal axis 50, this forming edge 76 starting from the closed end of the associated longitudinal opening 74 to that end of the inner tube section 56 or of the end section 52 of the first pipe section 46, on which the longitudinal opening 74 terminates.
- passage openings 78 located in the tube jacket of the inner pipe section 56 are simultaneously formed in their slipstreams (with respect to the flow of the exhaust gas 62).
- the exhaust pipe 30 supplied air partially in an angle with respect to the local portion of the longitudinal axis 50 extending directions and with a through the
- Flow guide 72 caused swirl flow into the flow of exhaust gas 62, which also has a positive effect on the mixing of the air 68 with the exhaust gas 62.
