Definitions
- the invention relates to a mixer for an exhaust system of an internal combustion engine or of a motor vehicle for mixing liquid and / or gaseous additives into an exhaust gas stream with at least one inlet tube having a tube axis, with at least one outlet tube having a tube axis and with a housing for receiving the tube Inlet tube and the outlet tube, wherein the outlet tube has an inner part arranged within the housing, which is provided for the purpose of discharging the exhaust gas from the housing with at least one outflow opening.
- the assembly includes an inlet tube and an outlet tube disposed in or on a housing.
- the inlet tube in this case runs in the tangential direction to the cylindrically shaped housing or the housing wall.
- the outlet tube is arranged, wherein a central axis of the outlet tube and a central axis of the housing are arranged offset parallel to each other.
- the outlet tube may also be arranged coaxially with the housing.
- the inlet tube is arranged coaxially with the cylindrical housing, while the outlet tube is placed in the radial direction of the housing.
- the center axis of the inlet pipe and the center axis of the outlet pipe are arranged in a plane.
- the center axis of the inlet tube and the center axis of the outlet tube are arranged parallel to each other, wherein the inlet tube and the outlet tube are placed outside the housing center.
- a double-shell exhaust pipe for receiving a mixing nozzle is known.
- the exhaust pipe has a lower flange for receiving an inflow pipe, wherein an output flange of the nozzle serves to receive an outflow pipe.
- the object of the invention is to design and arrange a mixer such that an extended variability with regard to use is ensured.
- the object is achieved according to the invention by the features of claim 1.
- This ensures that the relative position between the respective tube and the housing and / or the relative position of the tubes can be varied within the housing.
- This variation can be achieved as follows. i) By different orientation of the inlet tube or the outlet tube with respect to the same formation or the same passage.
- the inlet tube or the outlet tube can optionally be rotated or swiveled by 180 °, in order to change the orientation of the inlet and outlet, and thus the exhaust gas guide. This change in position can only be used for the inlet pipe and / or only for the outlet pipe.
- the center axes of each two formations or of two passages with the tube axis of the inlet tube and with the tube axis of the outlet tube can be brought into overlap, so that alternatively the inlet tube or the outlet tube with respect to the respective position R1, R2 in the housing shell or in the housing part or can be stored in the housing bottom.
- the gas guidance geometry can be achieved independently of the flexible mounting of the tubes according to variants i) and ii).
- the associated gas guide geometry is varied by changing the relative position of the two housing shells or housing walls to each other.
- a right angle ie 90 °, but also any angles is considered.
- the latter with respect to all three spatial axes, ie a pivot axis c, which is parallel to the tube axis, a pivot axis a, which is perpendicular to the tube axis and a pivot axis b, which is perpendicular to the tube axis and perpendicular to the pivot axis a.
- the shape of the respective edge of the housing ensures a receptacle of the respective tube over a partial circumference of about 180 °, so that storage and sealing of the respective tube over the circumference is ensured by both opposing formations as well as the passage.
- both tubes can also be exchanged with respect to their position in the housing.
- the same tube diameter D ensures the interchangeability of both tubes or any change of position within the housing.
- At least one further formation is provided with a central axis, which is employed with respect to the central axis of the other formation at an angle ⁇ , wherein the inlet pipe or the outlet pipe is an L, T or Y.
- -shaped basic form F has.
- the housing edge forming a graduation plane E is center-symmetrical with respect to a normal N of the graduation plane E or is symmetrical with respect to a straight line G of the graduation plane E. While the axisymmetric design of the housing edge allows a variation of the relative position of the two housing parts in two positions pivoted by 180 °, the point-symmetrical design ensures at least a variation within four positions, that is gradually by 90 °.
- the housing part in the region of the housing edge has a partially cylindrical basic shape F with a central axis b or a partially spherical basic shape F with a center M and an inner radius ri and an outer radius ra, wherein for the relationship between the Inner radius ri of the first housing edge and the outer radius ra of the second housing edge applies:
- a partially cylindrical design of the basic shape F ensures a preferably stepless pivoting of the two housing parts about the cylinder axis thus formed. This ensures optimum adaptation to the installation space conditions during assembly.
- the part-spherical basic shape F ensures preferably stepless relative pivoting of the two housing parts about the center of the sphere, ie around all three spatial axes. This leads to a further optimization with regard to an individual adaptation during assembly.
- both housing parts in the region of the partially cylindrical or partially spherical shape form a sliding seat which ensures said adaptation of the relative positions about the cylinder axis A on the one hand and the ball center M on the other hand.
- the inlet opening and / or the Outflow opening is formed by one or more recesses, which are optionally designed as a swirl flap.
- inlet opening as a perforation in the form of recesses ensures a standardization or homogenization of the gas stream entering the mixer.
- the characteristic as swirl flap ensures a good mixing in of the additive introduced in the outlet pipe.
- the inlet opening and / or the outflow opening has a hydraulic cross-section Q which varies in relation to the course of the tube axis.
- hydraulic cross-section Q increases with respect to the flow direction of the exhaust gas.
- the increase of the hydraulic cross-section Q facilitates the mixing or mixing to the end of the mixing chamber.
- a mixing element is provided with respect to the flow direction of the exhaust gas downstream of the outlet pipe.
- the supplementary arrangement of a mixing element ensures a further optimization of the entry of the additive into the gas stream.
- the further mixing element ensures a time-delayed admixture of a further additive.
- an additive supply unit for introducing the additive into the housing or into the inlet pipe or into the outlet pipe.
- the admixing of the additive takes place only in the outlet pipe, after the exhaust gas flow is unified via the inlet pipe and as far as symmetrically enters the inlet pipe.
- the inlet or outlet tube is conical. The conical design of the inlet and / or outlet tube ensures a further influencing of the flow conditions, in particular with regard to the hydraulic cross-section Q of the perforation or the swirl flaps. By rejuvenation of the tube, the gas flow or the dynamic pressure of the gas is increased, which in turn leads to an increase of the passing through the perforation or the swirl flaps flow.
- first housing part and the second housing part is in each case designed as a housing shell or as a housing bottom, wherein a housing shell is provided, which forms the housing together with the respective bottom.
- housing shells By using housing shells, the assembly is simplified as a whole.
- the housing consists in this case of only two components, which can be aligned and connected in different relative positions to each other due to the connection geometry of the housing edge as previously described.
- the inlet and outlet pipes can be varied within the formations or passages, which overall ensures a very simple structure and a multiplicity of possible variations.
- the formation of the housing as a winding housing d. H. the use of housing bottoms and a housing shell, ensures the above-mentioned variations in terms of the relative position of the housing parts on the one hand and the tubes on the other.
- the housing itself then consists of at least three components which are to be connected to the desired position.
- the housing can be produced by any manufacturing process, such as, for example, as a shell housing or as a winding housing.
