Description

The The invention relates to a cross-channel filter for filtering hot combustion exhaust gases from internal combustion engines. Such Cross-channel filters usually consist of a porous monolith or a perforated body with respect to a longitudinal axis more parallel to the longitudinal axis in a plane directly next to each other and one above the other in parallel planes equally juxtaposed and through Filter walls formed inlet channels. In addition, the cross-channel filter has several inlet channels crossing exhaust ports on which in one plane directly next to each other and on top of each other in parallel planes also directly arranged side by side and formed by filter walls are. The cross-channel effect is achieved by the fact that the Levels of inlet channels and levels of outlet channels alternate and the inlet channels through filter walls from the exhaust ducts extending across the inlet ducts are separated.

Further The invention relates to a housing assembly, with a cross-channel filter in an exhaust stream of an exhaust system of a Motor vehicle can be positioned.

The Combustion exhaust gas contains soot and ash particles, via the filter input side (first outside) through the inlet channels. Through a storage space in the housing assembly into which the inlet channels on the back of the filter (second outside), If an overpressure is generated in the inlet channels, through which the combustion exhaust gas through which formed as a filter wall Inner wall of the inlet ducts is routed so that the soot and ash particles on the inner wall of the inlet channels collect and called the filter exhaust gas filtered exhaust gas in the outlet channels flows. The inside the inlet channels are deposited soot particles burned by periodic energy directly in the Kreutzkanalfilter. Ideally, the entire soot particles burn residue-free, so only the ash particles from the inlet channels out promoted must become. In a non-ideal combustion process it can Occur that not all soot particles completely or burn completely residue-free, so that These then also promoted out of the inlet channels Need to become.

State of the art

From the EP 0 318 525 A and the EP 0 318 958 A Cross-channel filters are known in which the combustion exhaust gas inlet channels formed by filter walls are open on both opposite ends of the inlet channels, ie they have on both sides of the cross-channel filter an opening substantially equal in size to the constant channel cross-section. Through the opening on one side of the deposited on the inner wall of the inlet channels ash particles are transported into the storage space, which is designed as a collecting chamber. The filter exhaust gas is directed out of the housing assembly through exhaust passages formed by filter walls and open on one side.

From the DE 103 43 046 A Cross-channel filters are also known which function on the same operating principle with inlet channels open on both sides. The cross-channel filters described here have a semicircular filter cross-section. Due to this filter cross section, some inlet channels are reduced in their cross section, resulting in an asymmetric dynamic pressure distribution, an uneven deposition of soot and ash particles in the inlet channels, because the necessary for the removal of soot and ash particles flow dynamics in the inlet channels, which in are reduced in cross-section is not achieved.

So far, no sintered channel channel filter manufacturing processes are known since the structure is very difficult to produce. Due to the intersecting structures and the inlet channels open on both sides, they are obviously much more unstable than ceramic filters with inlet and outlet channels arranged in parallel and closed on one side, as used, for example, in US Pat EP 0 308 972 A2 are described as round ceramic filter with parallel and open on both sides inlet channels and without outlet channels, as in the US 6,233,926 B are described. Such ceramic filter with a honeycomb body, as in the US 6,233,926 B are described, due to their increased by the circular cross-section in the radial direction stability in the region of the end faces over the entire circumference in the radial direction on the lateral surface clamp.

For the assembly of cuboid sintered monoliths housing arrangements are known, as for example in the EP 0 318 958 A are described. This housing arrangement has an inlet connection for the combustion exhaust gas, at least one outlet connection for the filter exhaust gas and a collecting chamber for soot and ash. The inlet port is connected to the filter inlet side in a flow-tight manner. The collecting chamber is connected to the filter back side in a flow-tight manner and the outlet connection is connected to one of the two filter backs in a flow-tight manner. The other filter back is connected flow-tight to the housing assembly.

The invention has the object of providing a cross-channel filter and a housing assembly for a cross-channel filter in such a way and to arrange that a uniform distribution of the soot particles in the inlet channels is achieved and at the same time the lifetime of the cross-channel filter is increased. With respect to the housing arrangement, it is the objective to simplify the flow-tight connection while ensuring a symmetrical load and reduced voltage storage of the cross-channel filter.

The The basic idea is to use the outlet channels of the cross-channel filters as well as the intake channels on both sides of the Cross-channel filter to open, so that the flow of the filter exhaust on both sides of the outlet channels from the cross-channel filter can flow out. The on both sides of the respective outlet channel opposite openings correspond in their Size is essentially the remaining constant Channel cross section. The outlet channels formed by the filter wall thus allow along its flow cross-section two opposite flow directions of the medium too. The length of the channel is more than ten times larger than the diameter of the constant channel cross-section. The for the production of the inventive sintered cross channel filter with outlet channels open on both sides However, the process found so far is only economical if they be made cuboid.

By the two-sided opening of the outlet channels are opposite the one-sided closed outlet channels for 50% of the exhaust gas flow rate the flow paths reduced by 50%, resulting in a local increase in the flow rate in the outlet channels and to a more even Distribution of soot particles in the inlet channels leads. The thermal load of the cross-channel filter is due to the more uniform redox combustion reduces the soot particles during reheating, because the heat input is distributed more evenly is. A uniform heat input has a more even heat distribution for the benefit of which the voltages and thus the life of the Kreutzkanalfilters elevated.

moreover is reached through the outlet channels open on both sides, that the local flow speed on both sides the inlet channels is increased. Because the flow velocity decisive for the transport of the ash particles into the collecting chamber, is through the two-sided opening the ash transport improves.

It it was found to be for stability and thus also for the lifetime of the cross-channel filter as well essential for its production is that the outlet channels and the inlet channels directly next to each other and in layers are arranged because of this construction, in which the channels be formed by crossing filter walls, sufficient stability with regard to dynamic and thermal stresses during operation. Other forms of cross-channel filters, such as semicircular or tubular, which have higher load profiles remain out of consideration, since they are fluid dynamic as described above disadvantageous and not in the production are economical.

in addition comes that with this construction, in which the channels four sides of the cross-channel filter are open and thereby the cross-channel filter stored in the housing arrangement only over two sides higher demands can be made than if another third page, namely the one with the closed one Outlet channels, for storage of the cross-channel filter for Available. The inlet channels are on the filter input side and at the parallel arranged Filter back side open. The outlet channels are at the two opposite filter outlet sides (third and fourth outside) open.

Further lacks stability in this construction without the third side because the side with closed exhaust ducts not as carrying filter wall acts, so that the resulting reduced stability of the cuboid cross-channel filter according to the invention by the housing arrangement according to the invention must be compensated. The storage of a cuboid ceramic cross-channel filter exclusively via The two front ends is technically life-long with regard to Assembly not possible.

Solved The task of storage of the cross-channel filter is characterized in that the outlet through a flow channel forming housing part fluid-tight with the inlet nozzle is connected and the outlet channels of the cross-channel filter on both sides both on the third outside as well as on the arranged opposite third outside fourth outside in the flow channel open.

hereby is achieved that only two sides of the cross-channel filter, namely the filter input side and the filter output side via a clamping device called a mask, flow-tight must be connected to the housing assembly. The two filter output sides thus remain free of another Device that generates voltages across the cross-channel filter become. The cross-channel filter is a sintered component of a monolith, which is extremely sensitive to tension. ever less stress during assembly in the housing arrangement are introduced, the fewer voltages are at operating temperature generated.

It is advantageous for this purpose that the cross-channel filter with the fifth outside and with the sixth Outside is mounted on a bearing element of the housing part in the housing part, wherein the bearing element has two bearing surfaces for the two outer sides. The full-surface bearing of the cross-channel filter causes significantly less stress than the frontal storage, because the Kreutzkanalfilter is also secured against bending and thus a substrate break is prevented by bending stress. In this case, it is advantageous that the two inactive sides do not have to be sealed off towards the flow channel and the cross channel filter is supported over the entire surface in relation to the perpendicular and protected from the influence of the static and dynamic bending load by its weight mass.

moreover serves the storage area to the Kreutzkanalfilter over ceramic fiber material over the entire surface to protect against vibration and the housing assembly thermally isolate against the Kreutzkanalfilter, with the reheat and the following thermal redox reaction the housing assembly or it adjacent components are not overheated.

One additional advantage is according to one Training that the storage area between 80% and 120% the area size of the fifth Outside or the sixth outside. The over the side of the cross-channel filter out standing Bearing surface can thus partially a flow-conducting Have function.

Between the inlet and the outlet is a recording with two masks for the storage of the cross-channel filter and for the flow-tight connection, referred to as the filter input side first outside and as a filter back designated second outer side of the housing assembly arranged. The inlet nozzle is above the first mask relative to the filter inlet side fluidly to the Cross channel filter connected. The collecting chamber is over the second mask is opposite to that of the filter input side arranged filter backside fluid-tight the cross-channel filter is connected. It is advantageous for this, that the masks the cross-channel filter so in the range of the filter input side and framed in the area of the filter back that the masks at least partially on the four remaining outsides the cross-channel filter are arranged, which are to the filter input side and adjoin the filter back.

Advantageous It is also that the mask is formed at least in two parts and at least two frame parts, wherein the two frame parts after adjusted the insertion of a cross-channel filter in the mask and connected to each other. Due to the extreme production-related Dimensional tolerances of particular cuboid Sintered components, it is provided according to the invention, the mask as a bearing part immediately during assembly to the respective Adjust the size of the cross channel filter. there is to take into account that between the mask and the Kreutzkanalfilter preferred ceramic fiber mats are introduced, around the mask against over the cross channel filter on all to seal four pages.

there It is advantageously provided that the frame part is U-shaped or L-shaped or rod-shaped and the third to sixth outside framed. The for The storage necessary frame summarizes the filter input side or the filter back.

From of particular importance for the present invention, that the frame part is connected to the bearing element or after the insertion of a cross-channel filter in the mask with the bearing element connected is. Depending on the design of the housing arrangement form the mask and the bearing element are a one-piece component or connected to a one-piece component.

in the Connection with the training according to the invention and arrangement, it is advantageous that the cross-sectional profile of Mask or the frame part at least partially L- or U- or T- or double-T or I-shaped. According to the invention provided that the frame parts after the adjusted assembly also at operating temperatures sufficiently tight against the cross-channel filter and a certain degree of tolerance was not exceeded becomes. For this purpose, it is provided, the bending stiffness in one direction perpendicular to the respective outside of the cross-channel filter to increase by appropriate profiles that are very rigid are and in any operating point of the Kreutzkanalfilters plastic deform, so that the tightness is maintained. In this regard, It is essential that the frame parts at each operating point of the Kreutzkanalfilters do not exceed a certain gap, since the introduced between the frame parts and the Kreutzkanalfilter ceramic fiber mats fulfill their function only if they are sufficiently compressed.

It is also advantageous that between the mask and / or the bearing element and the cross-channel filter sealing material and / or bearing material and / or filling material, in particular ceramic fiber mats, wire mesh and / or cement is arranged. The cross-channel filter can not be stored and sealed directly over the frame parts, because the frame part is not sufficiently tight against the cross-channel filter and would be too large by the thermal movements and vibrations in Berieb the abrasion at the cross-channel filter. The flexible wire mesh is preferably used for storage in Direction of the longitudinal axis, since the cross-channel filter in this direction is mechanically loaded the most. The ceramic fiber mats are preferably used for sealing and are advantageously suitable for a planar bearing to fix the Kreutzkanalfilter frictionally without direct contact with a metallic component. They are fluid-tight on the respective outer side of the cross-channel filter. The filling material, such as cement, preferably serves to adapt the shape of the cross-channel filter over the outsides to a round mask in order to store it in a tube.

ever after choosing the material of the cross-channel filter, this can at least also partially by gluing or by soldering to the housing assembly attached and / or opposite the housing assembly be sealed.

Furthermore It is advantageous that the collecting chamber has a closable Access for the removal of soot and ash particles having. This access can be in the cross-channel filter separated and transported into the collecting chamber soot and remove ash particles continuously or discontinuously.

In 1 is a cross-channel filter 2 with a longitudinal axis 20 shown schematically. The cross channel filter 2 has a cuboid filter body with six outer sides A1-A6, of which two outer sides are arranged parallel to each other, ie in pairs opposite one another. The first outer side A1 forms the filter input side and is arranged parallel to the second outer side A2, the filter back. At these two sides, the third and fourth outer sides A3, A4 are arranged substantially at right angles. They form the filter exit sides A3, A4 and are also arranged parallel to each other. The fifth outer side A5 and the sixth outer side A6 are also arranged parallel to each other and are aligned substantially perpendicular to the other two pairs of outer sides A1-A4.

The cross channel filter 2 is a sintered monolith and consists of several inlet channels 21 and several outlet channels 22 that run transversely to each other. The inlet channels 21 run parallel to the longitudinal axis 20 and the outlet channels 22 in this embodiment, perpendicular to the inlet channels 21 , The inlet channels 21 are as well as the outlet channels 22 arranged in a plane parallel next to each other. In a direction perpendicular to the longitudinal axis 20 alternate the levels of inlet channels 21 and the levels of the outlet channels 22 from.

The sintered building material is porous, so that the supporting structure of filter walls 23 is formed. The inlet channels 21 as well as the outlet channels 22 be through these filter walls 23 formed parallel to and at right angles to the longitudinal axis 20 are arranged.

The inlet channels 21 extend from the filter input side A1 parallel to the longitudinal axis 20 up to the back of the filter A2 and are open on both sides. The openings 24 have substantially the same size as the rest of the channel cross-section. The outlet channels 22 are also open on both sides, so that two openings 25 for each of the outlet channels 22 are provided on both filter exit sides A3, A4.

In 2 a section of the filter back A2 is shown. The filter walls 23 form the entire supporting structure, so all the channels 21 . 22 of filter walls 23 be formed. In principle, the combustion exhaust gas to be filtered flows from the filter input side A1 through the intake passages 21 and becomes due to a pressure difference, which will be described below, through the filter walls 23 in the outlet channels 22 directed. It will be on the inner wall 23 the inlet channels 21 the soot and ash particles are separated from the combustion exhaust gas. After the periodic regeneration process, in which the soot particles were burnt without residue, the remaining and incombustible inert ash particles are transferred through the opening 24 the inlet channels 21 in an in 3 and 4 illustrated collection chamber 13 promoted. The filtered and called exhaust gas exhaust gas flows through the outlet channels 22 on both filter exit sides A3, A4 through two openings each 25 per outlet channels 22 from the cross-channel filter 2 out. Due to the symmetrical basic shape of the cross-channel filter 2 , which are connected to the rectangular cross-sections of the inlet and outlet channels 22 adjusted, is one in all intake channels 21 Most of the same dynamic pressure distribution adjustable, so that the combustion exhaust predominantly in the exhaust ducts 22 through the corresponding filter walls 23 flows and not from an inlet channel 21 through the filter wall 23 in the adjacent inlet channel 21 flows.

As in 3 and 4 is shown, the cross-channel filter 2 via a housing arrangement 1 integrated into an exhaust stream of an internal combustion engine not described. For this purpose, the housing arrangement 1 an inlet nozzle 10 for the exhaust gas, via the filter input side A1 of the cross-channel filter 2 to the inlet channels 21 connected. The inlet channels 21 flow into the collecting chamber 13 passing through the filter back A2 at the cross-channel filter 2 connected. The collecting chamber 13 is closed, so that the flow of combustion exhaust gas is backlogged and thereby through the filter walls 23 in the outlet channels 22 flows. In the collection chamber 13 they collect on the filter walls 23 deposited soot and ash particles and can if necessary have access 19 from the collection chamber 13 be removed.

The filter input side A1 and the filter back A2 are as in the 5 to 10c described in more detail on masks M1, M2 to the inlet nozzle 10 or to the collecting chamber 13 connected.

The housing arrangement 1 has a housing part 14 on that the inlet pipe 10 and an outlet 11 fluid-tight interconnects. The housing part 14 simultaneously encloses the two filter exit sides A3, A4 and forms a flow channel 15 in which the outlet channels 22 on both sides A3, A4 of the cross-channel filter 2 lead. Through the flow channel 15 the filter exhaust gas enters the outlet port 11 directed. On the fifth and sixth outside A5, A6 of the cross-channel filter 2 closes the housing part 14 the housing arrangement 1 as in 3 shown off. About these two sides A5, A6 is the cross-channel filter 2 in the housing arrangement 1 stored.

In 5 and 6 Two embodiments of masks M1, M2 are shown, with which the filter input side A1 and the filter rear side A2 are connected. For this purpose, the masks M1, M2 of one or more frame parts 18 formed indirectly via sealing material 3 that in the 7a to 10e is described in detail, resting on the outsides A3-A6. Due to the production-related strongly fluctuating dimensional tolerances of the sintered cross-channel filter 2 The masks M1, M2 to the cross-sectional shape of the cross-channel filter 2 customized. For this, the four in 5 represented or the two in 6 shown frame parts 18 aligned parallel and perpendicular to the outer sides A3-A6 and then via connecting seams 26 connected with each other.

In 7a is a two-part first mask M1 of two U-shaped frame parts 18 shown. The frame parts 18 show as in 7b and 7c illustrated a U-shaped cross-section or a rigid U-profile and are according to 7c put together and then connected. Between the frame parts 18 and the cross-channel filter 2 is sealing material 3 provided in the form of ceramic fiber mats, via which the filter inlet side A1 or the filter back A2 is sealed to the mask M1, M2 and also clamped. The ceramic fiber mat is compressed to a certain degree to fulfill its function. The mask M1, M2 itself becomes, as in 3 shown with the inlet nozzle 10 or with the collection chamber 13 connected fluid-tight. For this purpose, the mask M1, M2 with the inlet nozzle 10 or the collecting chamber 13 welded or glued or soldered.

In 8th an embodiment is shown with a two-part and U-shaped mask M1, M2, which has an I-profile. The mask M1, M2 is according to the embodiment according to 7a over the sealing material 3 connected to the filter input side A1.

The non-active fifth and sixth outer sides A5, A6 serve for the areal storage of the cross-channel filter 2 in the housing arrangement 1 , For this purpose, a bearing element 16 provided that between the two masks M1, M2 on the respective outer side A5, A6 is arranged and on the, as well as in 3 represented the cross-channel filter 2 over stock material 4 stored and thermally insulated. A sealing of one of the outer sides A3 to A6 is not necessary according to the invention, since the filter inlet side A1 and the filter rear side A2 are sealed via the masks M1, M2 and the outlet channels 22 via the filter outlet sides A3, A4 in the flow channel 15 lead.

In 9 is a one-piece mask M1 shown after measuring the cross-channel filter 2 made to measure.

According to the embodiment according to 10a to 10d it is intended, the cuboid cross-channel filter 2 through a filling material 5 to a tubular housing assembly 1 adapt. This is done on the cross-channel filter 2 on the two bearing sides A5, A6 and partly on the filter outlet sides A3, A4 filling material 5 for example, applied in the form of cement and then the round masks M1, M2 connected. The round connection technology allows a tension with a one-piece round frame part 18 in the circumferential direction, as in 10b is shown. The frame part 18 is fixed via a circlip in the axial direction. The circlip will after 10b above with the frame part 18 welded.
