Definitions

  • the present invention concerns an arrangement according to the preamble to claim l for aspirati ng , from an air cleaner in an air intake l ine for a combustion engine, particles that are captured in the air cleaner.

  • Airborne particles in the form of e.g . grit, sand , dust and soot are captured in the air cleaner and thereby prevented from being drawn into the combustion eng ine along with the intake air and causing damage in the combustion engine.
  • An air cleaner in a motor vehicle can, for example, be of the two-stage type, i .e. a so-called two-stage air cleaner.
  • a two-stage air cleaner comprises a pre-cleaner and one or more filter elements.
  • Heavier particles such as those in the form of sand and grit, are captured in the pre-cleaner in a first clean ing stage, whi le lighter particles are filtered out of the intake air by the fi lter element/elements in a subsequent cleaning stage.
  • the pre-cleaner is common ly of the centrifugal type, wherein the intake air is led into the pre-cleaner in such a way that it is caused to rotate in the pre-cleaner so that the heavier particles entrained in the intake air are thrown against the outer edges of the pre-cleaner by centrifugal force.
  • the intake air thus relieved of heavier particles is then led into the filter element/filter elements, where the lighter particles are captured via filtration , after which the filtered intake air is led on to the combustion engine.
  • Aspirating out the particles captured in the pre-cleaner by means of a suction line that is connected at its upstream end to an outlet of the pre-cleaner and connected at its downstream end to an exhaust pipe that is arranged so that exhaust gases from the combustion engine wil l flow through it is known from , for example, FR 889 243 A and US 3 1 37 553 A.
  • the suction line has, at its downstream end , a nozzle that extends into the exhaust pipe at a straight section of the exhaust pipe and has an outlet openi ng located on the center axis of the exhaust pipe .
  • a Venturi effect arises that generates the suction effect in the suction line .
  • the nozzle creates a relatively high exhaust gas counterpressu re in the exhaust line, wh ich resu lts in increased fuel consu mption by the combustion engi ne.
  • the nozzle is also preceded by a relatively long straight section of the exhaust pipe, which means that the exhaust pipe is relatively long and bu lky.
  • a long exhaust pipe is also relatively heavy and sensitive to vibration , wh ich results i n increased stresses on the exhaust pipe suspension elements and an increased risk of damage to the exhaust pipe. If the nozzle is d isposed too close to the outlet opening of the exhaust pipe , problems are also encou ntered with loud noise caused by the exhaust gas eddies that arise during the passage of the exhaust gases through the nozzle. This noise is reduced with a longer exhaust pipe section downstream of the nozzle. However, this also imposes more stringent requ irements in terms of the length of the exhaust pipe.
  • the object of the present invention is to achieve an arrangement of the type specified above that enables a mitigation of the foregoing problems.
  • said object is ach ieved by means of an arrangement exhibiting the features defined in claim 1 .
  • the arrangement accord ing to the invention comprises :
  • suction li ne that is connected at its upstream end to an outlet of an air cleaner and connected at its downstream end to the exhaust pipe .
  • the suction line has an outlet section that extends into the exhaust pipe from a wall section of the exhaust pipe located on the rad ially inner part of said bend , wherein an outlet opening of said outlet section is located in an area in the exhaust pipe downstream of the bend where, during the passage of the exhaust gases through the bend, a negative pressure is generated u nder the action of centrifugal force that acts upon exhaust gases flowi ng through the bend so as to thereby enable the generation of a suction effect in the suction l ine u nder the action of the negative pressure in said area of the exhaust pipe .
  • the radial ly inner part of a bend refers in this description and the subsequent claims to that part of the bend that lies closest to the center of curvature of the bend .
  • the rad ially outer part of the bend consequently refers to that part of the bend that is located furthest from the center of curvatu re of the bend .
  • this natural ly occurring negative pressure in the bend is used to generate the desired suction effect in the suction line that is used to aspirate, from the air cleaner, particles captu red therein .
  • the outlet section of the suction line is arranged in an area of the exhaust line where negative pressure prevails, said outlet section will contribute relatively l ittle to the exhaust gas cou nterpressure in the exhaust pipe. With this placement of the outlet section , the outlet section will not cause any noise-generating eddy formation in the exhaust gases flowing through the exhaust pipe either.
  • the solution according to the invention also obviates the need for a longer straight exhaust gas section upstream of that part of the where the suction line is connected to the exhaust pipe , wh ich thus entails that a shorter and lig hter exhaust pipe can be used as compared to what is the case for the prior art solutions described in the aforementioned patents .
  • said outlet opening of the outlet section is tu rned toward the downstream end of the exhaust pipe .
  • the air f lowing through the suction line will flow out into the exhaust pipe in essentially the same direction as the exhaust gas flow, resu lting in a more u niform flow in the relevant part of the exhaust pipe , and a consequent reduction in the exhaust gas cou nterpressure in the exhaust pipe .
  • the outlet section has a wall that extends into the exhaust pipe and forms a screen inside the exhaust pipe at the outlet opening of the outlet section , wherein said screen prevents the exhaust gases flowing through the exhaust pipe from penetrating into the suction line via the outlet opening of the outlet section.

  • An air cleaner 4 of a type that is known per se is arranged in the air intake line 3 so as to capture particles that are entrained in the intake air.
  • the exhaust gases that leave the combustion engine 2 are led through an exhaust line 5 to an exhaust gas post-processing device 6. After their passage through the exhaust gas postprocessing device 6 , the exhaust gases are led through an exhaust pipe 21 arranged downstream of the exhaust gas postprocessing device and released into the su rroundings via an exhaust gas outlet 22 at the downstream end 23 of the exhaust pipe.

Abstract

La présente invention concerne un agencement permettant d'aspirer des particules qui sont capturées dans un filtre à air (4), comprenant : un tuyau d'échappement (21) qui comporte un coude (24), et une conduite d'aspiration (25) qui est reliée au niveau de son extrémité en amont (26) à une sortie (13) du filtre à air (4) et qui est reliée au niveau de son extrémité en aval (27) au tuyau d'échappement. Au niveau de son extrémité en aval, la conduite d'aspiration comporte une section (28) de sortie qui s'étend dans le tuyau d'échappement à partir d'une section de paroi du tuyau d'échappement située sur la partie (30) radialement intérieure dudit coude, une ouverture de sortie de ladite section de sortie étant située dans une zone (32) dans le tuyau d'échappement en aval du coude dans laquelle, lors du passage de gaz d'échappement à travers le coude, une pression négative est créée sous l'action d'une force centrifuge qui agit sur les gaz d'échappement circulant à travers le coude de sorte à permettre ainsi la génération d'un effet d'aspiration dans la conduite d'aspiration sous l'action de la pression négative dans ladite zone du tuyau d'échappement. L'invention concerne également un véhicule automobile contenant un tel agencement.
