Definitions
- the present invention relates to an exhaust system for an internal combustion engine, in particular of a motor vehicle, with the features of claim 1.
- Such an exhaust system is known for example from US 5,666,805 and comprises an exhaust pipe which is connected to a catalyst unit containing a housing in a monolith whose cross section is greater than a cross section of the exhaust pipe at a mouth end of the exhaust pipe.
- the catalyst unit also has a funnel to which the exhaust pipe is connected.
- the funnel is designed as an angle piece, so that the exhaust pipe and catalyst unit can be mounted with mutually inclined longitudinal central axes.
- the exhaust pipe is formed at its mouth end and dimensioned so that it can be inserted into the associated funnel end. In the known exhaust system, the exhaust pipe does not protrude into the funnel, but ends in the associated funnel end.
- a catalyst unit which contains a catalytically active monolith in a housing.
- a cross section of this monolith is larger than a cross section of an exhaust pipe to which the catalyst unit is to be connected.
- the housing comprises a funnel which can be connected at one end to the exhaust pipe and at the other end passes into the housing, with the funnel expanding correspondingly between its ends.
- the connection point, in which the exhaust pipe is connected to the funnel lies outside a funnel interior.
- the known catalyst unit also has a arranged in the funnel, longitudinally adjustable flow guide, which defines depending on its relative position through which the exhaust gas flowed through cross section of the monolith, so as to accelerate the achievement of the light-off temperature of the catalyst. The installation of such a flow guide is associated with a relatively high cost.
- a further catalyst unit which has a housing in which a monolith is arranged.
- the monolith is fixed with a securing or retaining element in the housing.
- the housing is equipped at its ends with funnels, which taper from the large cross section in the area of the monolith to a small cross section up to a flange.
- the funnels comprise an outer funnel on each side of the housing and an inner funnel concentrically arranged therein, which is dimensioned such that it covers the cross-section of the monolith as close as possible to the monolith. This ensures that the securing or retaining element is exposed during operation no gas flow.
- the housing is connected to exhaust pipes. The installation of such additional inner funnel is associated with a relatively high cost.
- the present invention addresses the problem of providing for an exhaust system of the type mentioned in an improved embodiment, which in particular has a simple structure and is inexpensive to produce.
- the present invention is based on the general idea, the housing of the catalyst or particulate filter unit and the exhaust pipe to be connected to match so that the exhaust pipe in the hopper of the housing laterally, ie opposite a longitudinal central axis of the monolith and the filter body is inserted from the outside inclined , In this way, the connection of the exhaust pipe to the housing of the catalyst or particle filter unit is simplified.
- the side of the exhaust pipe in the funnel there is also the possibility, by an appropriate design of the mouth end within the funnel Funnel targeted to produce a desired flow guidance. In particular, this makes it possible to optimize the distribution of the supplied exhaust gases to the monolith or filter body cross section.
- formed by the projecting into the funnel interior mouth end between the funnel and the exhaust pipe from an annular gap which is virtually not flowed through during operation and thus causes a thermal insulation for the hopper.
- the mouth end is arranged so that it lies in a plane whose normal is inclined relative to the longitudinal center line of the exhaust pipe in the mouth end.
- the mouth end lies in a plane whose normal runs substantially parallel to the longitudinal central axis of the monolith or of the filter body.
- the exhaust pipe is quasi beveled at its mouth end, whereby the outlet cross-section increases at the mouth end, without having to be expanded, the exhaust pipe.
- the exhaust gas flow can be widened with the help of the so-designed mouth end in the funnel interior, although the exhaust pipe with its mouth end from the outside, ie from the monolith or from the filter body side facing away from the funnel can be inserted.
- a flow-conducting Shaping at the mouth end can thus be realized in the exhaust system according to the invention without much effort.
- an exhaust system 1 according to the invention and only partially shown comprises at least one exhaust pipe 2 shown here only in one end section and a catalyst or particulate filter unit 3 connected thereto, which is also shown only in a section connected to the exhaust pipe 2 ,
- the exhaust system 1 is for attachment to an internal combustion engine, not shown here, which may be housed in particular in a motor vehicle, suitable and serves to dissipate the exhaust gases generated by the internal combustion engine.
- the catalyst or particle filter unit 3 comprises a housing 4, in which at least one monolith or at least one filter body 5 is accommodated.
- the monolith 5 or the filter body 5 is usually stored or positioned in the housing 4 with a bearing mat, not shown here.
- the filter body 5 may be, for example, a soot filter.
- the catalyst or particle filter unit 3 also has a funnel 6, which is connected with a first end 7 to the exhaust pipe 2 and with a second end 8 to the housing 4.
- the monolith or filter body 5 usually has a cross section 9, which is significantly larger than a cross section 10 of the exhaust pipe 2 in the region of the first funnel end 7. Accordingly, the funnel 6 widens from its first end 7 to its second end 8.
- the monolith or filter body cross section 9 is also larger than a cross section 11 of a mouth end 12 of the exhaust pipe 2.
- the monolith or filter body cross section 9 and the exhaust pipe cross section 10 are here transverse to the longitudinal central axis 13 of the monolith or filter body 5 and transverse to a longitudinal center line 14 of the exhaust pipe 2 measured.
- the orifice cross section 11 is measured in a plane 21, in which the mouth end 12 extends.
- the exhaust pipe 2 is inserted concentrically with its mouth end 12 in the first funnel end 7, so that the longitudinal center line 14 of the exhaust pipe 2 coincides with a first longitudinal center axis 15 of the funnel 6, as long as the longitudinal center line 14 of the exhaust pipe 2 extends in a straight line. Furthermore, a second longitudinal central axis 16 of the funnel 6 coincides with the longitudinal central axis 13 of the monolith or of the filter body 5, since the monolith or filter body 5 is arranged concentrically with respect to the second funnel end 8.
- the funnel 6 is shaped such that its ends 7, 8 are inclined relative to one another, ie the first longitudinal central axis 15 and the second longitudinal central axis 16 of the funnel 6 are not parallel to each other, but are inclined to each other.
- the exhaust pipe 2 does not axially connect with respect to the longitudinal central axis 13 of the monolith or of the filter body 5, but laterally against the funnel 6.
- the exhaust pipe 2 is inserted into the first funnel end 7, such that the mouth end 12 of the exhaust pipe 2 protrudes through the first funnel end 7 and projects into a funnel interior 17.
- the configuration of the exhaust pipe 2 and the geometry of the first funnel end 7 are coordinated with one another such that the exhaust pipe 2 is away from the side facing away from the monolith or from the filter body 5 through the first funnel opening 7 in the hopper interior 17 can be inserted.
- a perpendicular to the longitudinal center line 14 of the exhaust pipe 2 measured cross section is constant and / or always equal to or smaller than an open inner cross section of the first funnel end 7.
- the exhaust pipe 2 may be formed so that its longitudinal center line 14 in the hopper interior 17 is rectilinear. Such an exhaust pipe 2 is particularly easy to produce. The insertion of the exhaust pipe 2 in the funnel 6 is characterized very simple.
- the exhaust pipe 2 is formed so that its longitudinal center line 14 within the hopper interior 17 has a curved course. Accordingly, this longitudinal center line 14 in the hopper interior 17 deviates from the first longitudinal central axis 15 in the first end 7 of the hopper 6.
- This course of the longitudinal center line 14 is achieved in that the exhaust pipe 2 is bent without changing its cross section in terms of shape and / or surface accordingly. It is important to ensure that the radii of curvature formed are chosen so that the exhaust pipe 2 in the desired manner in the first funnel end 7 can be inserted from the outside.
- this embodiment is somewhat more expensive to assemble, it opens up greater possibilities for the design of the flow guidance in the interior of the catalyst or particle filter unit 3.
- the exhaust pipe 2 inserted laterally into the funnel 6 is used to influence the flow in the interior of the catalyst or particle filter unit 3.
- the mouth end 12 in the plane 21 whose normal or perpendicular to the longitudinal center line 14 is inclined at the point of intersection 19 with said mouth end plane 21.
- this inclination is - as here - chosen so that the muzzle end plane 21 extends substantially parallel to an end face 20 of the monolith and the filter body 5. That is, the normal or vertical of the muzzle end plane 21 extends substantially parallel to the longitudinal central axis 13 of the monolith and the filter body 5.
- the flow guide from the mouth end 12 to the end face 20 of the monolith and the filter body 5 can be influenced and designed specifically. In particular, it is thereby possible to distribute the hot exhaust gas flow in a desired manner to the cross section of the monolith or of the filter body 5.
- a flow guide can be expedient in which, with regard to gas temperature and / or flow velocity, a symmetrical, in particular uniform, distribution in monolith or filter body cross-section 9 forms.
- the area of the exhaust line 1 shown in FIGS. 1 and 2 may be formed at the inlet of the catalyst or particle filter unit 3, so that then the funnel 6 forms an inlet funnel 6.
- the catalyst or particle filter unit 3 may be designed according to the invention at its outlet, so that then the funnel 6 is designed as outlet funnel.
