It is shown in: Fig. 1 a principle sketch of an arrangement according to the present invention, Fig. 2 a perspective view from the side of an exhaust pipe included in an arrangement according to an embodiment of the invention, Fig. 3 a plan view from above of the exhaust pipe according to Fig. 2, Fig. 4 a longitudinal section through the exhaust pipe according to Fig. 2, and Fig. a cross section through the exhaust pipe according to Fig. 2.

DETALJERAD BESKRIVNING AV UTFORINGSFORMER AV 15 UPPFINNINGEN I Fig 1 illustreras mycket schematiskt ett motorfordon 1 forsett med en forbranningsmotor 2 och en luftintagsledning 3 for insugning av inloppsluft till forbranningsmotorn 2. I luftintagsledningen 3 är en luftrenare 4 av i sig kand typ anordnad for uppfangning av partiklar som medfors av inloppsluften. Avgaserna som lamnar forbranningsmotorn 2 leds genom en avgasledning 5 till en avgasefterbehandlingsanordning 6. Efter sin passage genom avgasefterbehandlingsanordningen 6 leds avgaserna genom ett nedstroms avgasefterbehandlingsanordningen anordnat avgasror 21 och avges till omgivningen via ett avgasutlopp 22 vid avgasrorets nedstromsande 23. I avgasroret 21 aterfinns en rorkrok 24, genom vilken avgaserna strommar vid sin forflyttning mellan avgasefterbehandlingsanordningen 6 och avgasutloppet 22. 7 Motorfordonet 1 innefattar ett arrangemang 20 enligt foreliggande uppfinning far att fran luftrenaren 4 suga ut partiklar som fangats upp i luftrenaren. Detta arrangemang 20 innefattar det ovan namnda avgasroret 21 och dessutom en sugledning 25, vii- ken vid sin uppstrOmsande 26 är ansluten till luftrenaren 4 och vid sin nedstromsande 27 är ansluten till avgasroret 21. DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION Fig. 1 very schematically illustrates a motor vehicle 1 provided with an internal combustion engine 2 and an air intake line 3 for sucking in intake air to the internal combustion engine 2. which is carried by the inlet air. The exhaust gases leaving the internal combustion engine 2 are led through an exhaust line 5 to an exhaust aftertreatment device 6. After their passage through the exhaust aftertreatment device 6, the exhaust gases are led through an exhaust pipe 21 arranged downstream of the exhaust aftertreatment device and discharged to the environment via an exhaust pipe 22. , through which the exhaust gases flow during their movement between the exhaust after-treatment device 6 and the exhaust outlet 22. The motor vehicle 1 comprises an arrangement 20 according to the present invention for sucking out particles trapped in the air cleaner from the air purifier 4. This arrangement 20 comprises the above-mentioned exhaust pipe 21 and in addition a suction line 25, which at its upstream 26 is connected to the air purifier 4 and at its downstream 27 is connected to the exhaust pipe 21.

I det i Fig 1 illustrerade exemplet är luftrenaren 4 en tvastegsluftrenare med en forrenare 8 och ett cylindriskt filterelement 9, vilka ar anordnade i ett gemensamt holje 10. Tyngre partiklar som medfoljer inloppsluften uppfangas i forrenaren 8 i ett forsta reningssteg och lattare partiklar bortfiltreras fran inloppsluften i filterelementet 9 i ett efterfoljande andra reningssteg. Den illustrerade forrenaren 8 är av centrifugaltyp och anordnad radiellt ut- vandigt om filterelementet 9. Forrenaren 8 utgors i detta fall av ett cyldindriskt utrymme mellan filterelementet 9 och holjet 10. Inloppsluften leds in i forrenaren 8 via ett i holjet 10 anordnat inlopp 11 pa ett sadant satt att inloppsluften bringas att rotera i forrenaren 8 runt om filterelementet 9 sa att de tyngre partiklar som medfoljer inloppsluften in i luftrenaren 4 slungas ut mot forrena- rens ytterkanter, dvs mot insidan av holjet 10, under verkan av centrifugalkraften. Den fran tyngre partiklar befriade inloppsluften sugs via filterelementets mantelyta vidare in i filterelementet 9 dar de lattare partiklarna bortfiltreras, varefter den filtrerade in- loppsluften leds vidare till forbranningsmotorn 2 via ett forsta ut- lopp 12 hos luftrenaren 4. De i forrenaren 8 uppfangade partiklarna sugs ut ur luftrenaren 4 genom sugledningen 25, vilken ar ansluten till ett andra utlopp 13 hos luftrenaren 4. Det forsta utloppet 12 är anordnat i en gavel 14 hos holjet 10 och anslutet till ett utrymme 15 i centrum av filterelementet 9, medan det andra 8 utloppet 13 är anordnat vid mantelytan 16 hos holjet 10 och anslutet till den radiellt yttre delen av forrenaren 8. In the example illustrated in Fig. 1, the air purifier 4 is a two-stage air purifier with a pre-purifier 8 and a cylindrical filter element 9, which are arranged in a common housing 10. Heavier particles accompanying the inlet air are trapped in the pre-purifier 8 in a first purification stage and lighter particles are filtered out from the inlet air. in the filter element 9 in a subsequent second purification step. The illustrated pre-cleaner 8 is of the centrifugal type and is arranged radially outside the filter element 9. The pre-cleaner 8 in this case consists of a cylindrical space between the filter element 9 and the housing 10. The inlet air is led into the pre-cleaner 8 via an inlet 11 arranged on the housing 10. so that the inlet air is caused to rotate in the pre-cleaner 8 around the filter element 9 so that the heavier particles which accompany the inlet air into the air cleaner 4 are thrown out towards the outer edges of the pre-cleaner, i.e. towards the inside of the housing 10, under the action of centrifugal force. The inlet air freed from heavier particles is sucked via the jacket surface of the filter element further into the filter element 9 where the lighter particles are filtered out, after which the filtered inlet air is led to the combustion engine 2 via a first outlet 12 of the air cleaner 4. The particles trapped in the pre-cleaner 8 are sucked out of the air cleaner 4 through the suction line 25, which is connected to a second outlet 13 of the air cleaner 4. The first outlet 12 is arranged in an end 14 of the housing 10 and connected to a space 15 in the center of the filter element 9, while the second 8 outlet 13 is arranged at the mantle surface 16 of the housing 10 and connected to the radially outer part of the pre-cleaner 8.

Vid sin nedstromsande 27 uppvisar sugledningen 25 ett ut- loppsparti 28 som stracker sig in i avgasroret 21 fran en vagg- sektion 29 hos avgasroret belagen vid den radiellt inre delen 30 av rorkroken 24, sasom visas i narmare detalj i Fig 2-5. I Fig 3 ar den del av utloppspartiet 28 som befinner sig inuti avgasroret 21 markerad med streckade linjer. En utloppsoppning 31 hos ut- loppspartiet 28 är belagen i ett omrade 32 i avgasroret ned- stroms rorkroken 24 dar det vid avgasernas passage av rorkroken bildas ett undertryck under verkan av den centrifugalkraft som verkar pa de genom rorkroken 24 strommande avgaserna. Under verkan av undertrycket i detta omrade 32 i avgasroret 21 genereras en sugverkan i sugledningen 25 och denna sugverkan astadkommer i sin tur utsugning av de i forrenaren 8 uppfangade partiklarna. Dessa partiklar och medfoljande luft strommar ut i avgasroret 21 via utloppsoppningen 31 hos sugledningens utloppsparti 28 och avges till omgivningen via avgasutloppet 22. At its downstream 27, the suction line 25 has an outlet portion 28 which extends into the exhaust pipe 21 from a cradle section 29 of the exhaust pipe located at the radially inner part 30 of the pipe hook 24, as shown in more detail in Figs. 2-5. In Fig. 3, the part of the outlet portion 28 which is located inside the exhaust pipe 21 is marked with dashed lines. An outlet opening 31 of the outlet portion 28 is located in an area 32 in the exhaust pipe downstream of the rudder hook 24 where a negative pressure is formed during the exhaust gas passage of the rudder hook under the action of the centrifugal force acting on the exhaust gases flowing through the rudder hook 24. Under the action of the negative pressure in this area 32 in the exhaust pipe 21, a suction action is generated in the suction line 25 and this suction action in turn causes suction of the particles trapped in the pre-cleaner 8. These particles and accompanying air flow out into the exhaust pipe 21 via the outlet opening 31 of the suction line 28 outlet portion and are discharged to the environment via the exhaust outlet 22.

Nar de genom avgasroret 21 strommande avgaserna passerar rorkroken 24 pressas de av centrifugalkraften mot den radiellt yttre delen 33 av rorkroken, varigenom det uppstar ett undertryck i det omrade 32 av avgasrOret som är belaget precis nedstroms den radiellt inre delen 30 av rorkroken. Detta undertryck utnyttjas for att generera sugverkan i sugledningen 25. As the exhaust gases flowing through the exhaust pipe 21 pass the rudder hook 24, they are pressed by the centrifugal force against the radially outer part 33 of the rudder hook, whereby a negative pressure arises in the area 32 of the exhaust pipe which is located just below the radially inner part 30 of the rudder hook. This negative pressure is used to generate the suction effect in the suction line 25.

Utloppsoppningen 31 hos utloppspartiet 28 är lampligen vand mot avgasrorets nedstromsande 23. Utloppspartiet 28 uppvisar en vagg 34 som stracker sig in i avgasroret 21 och bildar en av- 9 skarmning 35 inuti avgasroret for utloppspartiets utloppsoppning 31. Denna avskarmning 35 hindrar de genom avgasroret 21 strommande avgaserna att tranga in i sugledningen 25 via utloppspartiets utloppsoppning 31. Utloppspartiet 28 är foretrades- vis rorformigt. The outlet opening 31 of the outlet portion 28 is suitably watered towards the downstream 23 of the exhaust pipe. The outlet portion 28 has a cradle 34 which extends into the exhaust pipe 21 and forms a shield 35 inside the exhaust pipe for the outlet portion 31 of the outlet portion. the exhaust gases to penetrate into the suction line 25 via the outlet opening 31 of the outlet portion 31. The outlet portion 28 is preferably tubular.

Det uppfinningsenliga arrangemanget är sarskilt avsett att anvandas i ett tungt motorfordon, sasom exempelvis en buss, ett dragfordon eller en lastbil. The arrangement according to the invention is particularly intended for use in a heavy motor vehicle, such as, for example, a bus, a towing vehicle or a truck.

Uppfinningen är givetvis inte pa nagot satt begransad till de ovan beskrivna utforingsformerna, utan en mangd mojligheter till modifikationer darav torde vara uppenbara for en fackman pa omradet, utan att denne for den skull avviker fran uppfinningens grundtanke sadan denna definieras i bifogade patentkrav. Det uppfinningsenliga arrangemanget kan exempelvis vara anordnat att suga ut partiklar fran en luftrenare som har annan utformning an den som illustreras i Fig 1. The invention is of course not limited in any way to the embodiments described above, but a number of possibilities for modifications thereof should be obvious to a person skilled in the art, without this deviating from the basic idea of the invention as defined in the appended claims. The arrangement according to the invention can for instance be arranged to suck out particles from an air purifier which has a different design than that illustrated in Fig. 1.
