Definitions

  • the invention relates to a device and a method for limiting the exhaust gas particle emission when charging internal combustion engines, consisting essentially of a pressure wave machine with charge air flap and / or recirculation flap, and / or exhaust gas bypass valve, and exhaust manifolds opening into an exhaust gas receiver.
  • a reduction of the particle emission in internal combustion engines by measures within the internal combustion engine is not yet possible as of today, however progress has already been made in influencing the particle emission by exhaust gas aftertreatments.
  • the main focus is on processes for the post-combustion of free-floating soot and unburned high-boiling hydrocarbons as well as soot separation by exhaust gas filtering.
  • the exhaust gas temperature after the pressure wave machine is lower than, for example, when charging with a turbocharger because of the purge air.
  • the external energy supply for burning the soot is greater when it is charged with a pressure wave machine.
  • the invention seeks to remedy this.
  • the invention as characterized in the claims, achieves the object of providing a device whereby the particle emission from internal combustion engines charged with pressure wave machines is optimally limited by the exhaust gas particle filter being arranged in the high pressure part of the exhaust system in front of the pressure wave machine.
  • the filter is arranged in the exhaust gas receiver itself.
  • the advantage of this arrangement can be seen in the fact that the hot exhaust gases flowing out of the internal combustion engine can be used for soot combustion without losses.
  • the filter is arranged in a separate section from the actual exhaust gas receiver in the exhaust gas direction immediately before the pressure wave machine.
  • the filter is designed as an interchangeable unit.
  • the filter consists of a monolithic porous and heat-resistant core.
  • the particles present in the exhaust gas hit the surface of the exhaust gas particle filter and agglomerate there in larger particles, whereby the surface quality and the porosity of the exhaust gas particle filter material play a decisive role for the accumulation and agglomeration processes of the soot particles as well as for their combustion.
  • the core of the filter is surrounded by a fibrous mat-like and heat-resistant covering.
  • the core of the filter assembly of the casing is arranged in a cylindrical support tube which is held at one end by the retaining ring provided in the exhaust gas receiver and at the other end by the retaining cam provided in the exhaust gas receiver.
  • the cylindrical support tube is fixed between the flange of the exhaust gas receiver and the flange of the section.
  • the core of the filter is rigidly integrated with the interposition of the fibrous mat-like covering through the cylindrical support tube and its position is precisely fixed in the axial and radial directions.
  • the support tube consists of heat-resistant sheet metal and an elastic, heat-resistant layer is arranged between it and the solid jacket of the section of the exhaust gas receiver.
  • the monolithic porous core of the filter consists of a ceramic material with high thermal shock resistance or steel wool. With these two materials, optimal filter properties are achieved at higher temperatures, taking into account the temperature change.
  • the charge air flap in the charge air line is briefly closed and operated again after the filter has been successfully regenerated.
  • the recirculation flap in the fresh air intake line of the pressure wave machine is closed at short notice and is operated again normally after the filter has been successfully regenerated.
  • the exhaust gas temperature upstream of the filter is increased by briefly opening the exhaust gas bypass valve and operated again after the filter has been successfully regenerated.
  • the exhaust gas bypass valve is arranged in the bypass between the exhaust gas housing and the exhaust line of the pressure wave machine.
  • the method steps according to claims 15-17 are used alternatively. Thus, a number of process options are available to control the exhaust temperature increase in front of the filter and burn soot deposits on the surface of the filter.
  • FIG. 1 shows a cylinder head 1 with six cylinders 2.
  • an inlet / suction channel 3 is arranged for each cylinder, which open into a manifold 4.
  • the manifold 4 is connected to the pressure wave machine 7 through the charge air line 5, in which the charge air flap 6 is located.
  • the exhaust gas channel 8 for each cylinder, to which the exhaust manifolds 9 are connected and which open into an exhaust gas receiver 10.
  • the exhaust gas receiver 10 is connected to the Intermediate piece 11 connected to the exhaust housing 13 of the pressure wave machine 7.
  • the charge air line 5 opens into the pressure wave machine 7, and the fresh air intake line 14 with recirculation flap 37 and the exhaust line 15 are also connected.
  • the exhaust gas bypass valve 36 is located in a bypass 35 between the exhaust gas housing 13 and the exhaust line 15.
  • the mode of operation of the charge air flap 6, the recirculation flap 37 and the exhaust gas bypass valve 36 is subsequently described in more detail in connection with the description of FIG. 4 in connection with the mode of operation of the filter 18 during driving operation explained.
  • the pressure wave machine 7 is driven via a pulley 16 by the motor shaft 17, the connection of V-belts 16 'between the pulley 16 and the motor shaft 17 or the motor pulley 17' being shown only schematically in the drawing for reasons of better clarity.
  • the exhaust gas particle filter 18 is arranged in the exhaust gas receiver 10 itself.
  • the particle filter 18 is only indicated in FIG. 1, but is shown and explained in detail in FIG. 3.
  • the end plate 27 by means of a screw bolt 29, washer 30 and nut 31 with the flange 22 of the exhaust gas receiver 10 and on the other hand the flange 21 of the exhaust gas receiver 10 is also screwed to the flange 19 of the intermediate piece 11 releasably connected.
  • the intermediate piece 11 in turn connects the exhaust gas receiver 10 to the exhaust gas housing 13 of the pressure wave machine 7 and is removably arranged by the flange connection 19, 21 and the flange connection 20, 23.
  • FIG. 2 shows a schematic illustration of a second variant of the exhaust gas particle filter arrangement.
  • the filter 18 is arranged in a section 12 separated from the actual exhaust gas receiver 10 in the exhaust gas direction directly in front of the pressure wave machine 7.
  • the exhaust gas receiver 10 has a smaller diameter than the first variant (FIG. 1) and extends to the section 12.
  • the intermediate piece 11 is omitted in this arrangement.
  • the section 12 is also arranged to be removable.
  • the flange 12 'of the section 12 is detachably connected to one another by a screw connection with the flange 21 of the exhaust gas receiver 10, and on the other hand the flange 1.2 "is also connected to the flange 23 of the exhaust gas housing 13 of the pressure wave machine 7 with a screw connection.
  • Fig. 3 - here the same reference numbers apply as in Fig. 1 - a section through the exhaust gas particle filter arrangement according to the first variant in Fig. 1 is shown. For the sake of clarity, however, only the exhaust gas receiver ends and part of the exhaust gas receiver 10 and part of the filter 18 are shown.
  • the filter 18 consists of a monolithic, porous, heat-resistant and cylindrical core made of ceramic material cf. e.g. SAE-Paper No. 810114 of February 23, 1981 "Cellular Ceramic Diesel Particulate Filters” by John S. Howitt et al, and is provided with a fibrous and heat-resistant mat-like covering 24 made of ceramic or mineral fiber material, the ends 24 ' of the mat-like covering 24 protrude beyond the cylindrical filter 18 in the axial direction and are inclined inwards towards the axis, as a result of which the position of the filter 18 is fixed in the longitudinal direction.
  • the filter 18 together with the cover 24 is fastened in a support tube 25, which consists of heat-resistant sheet metal, which encloses the filter 18 together with the cover 24 under contact pressure, the ends of the support tube 25 being welded along a surface line.
  • the annular exhaust gas inflow space 39 is located between the support tube 25 and the solid casing of the exhaust gas receiver 10. According to the direction of the arrows with the reference number 40, the exhaust gas flows out of the exhaust gas channels 8 into the agas inflow space 39 and from there into the filter antechamber 41.
  • the exhaust gas inflow space 39 and the filter anteroom 41 are connected to one another. After the exhaust gas has passed through the filter 18, it reaches the intermediate piece 11 and is fed from there to the exhaust gas housing 13 of the pressure wave machine 7.
  • a retaining ring 26 is arranged at the downstream end of the exhaust gas receiver 10 and at least four retaining cams 28 are each arranged concentrically at the other end of the exhaust gas receiver 10.
  • An asbestos seal 33 is located between the holding ring 26 and the support tube 25 in order to prevent exhaust gas from reaching the intermediate piece 11 g bypassing the filter 18, while the asbestos seals 33 ′ take over the sealing against the environment.
  • Fig. 4 - here the essentially the same reference numerals as in Fig. 3 apply - a section through the exhaust gas particle filter arrangement according to the variant in Fig. 2 is shown.
  • the construction of the filter 18 is the same as described in detail in FIG. 3.
  • a flange 25 ' is provided, which is clamped between the flange 21 of the exhaust gas receiver 10 and the flange 12' of the section 12 and is fastened by a screw connection 29, 30, 31.
  • An elastic heat-resistant layer 34 made of wire mesh is located between the support tube 25 and the solid jacket of the section 12.
  • the one-sided fastening of the support tube 25 and the lining with the elastic, heat-resistant layer 34 was chosen in order to dampen any vibrations of the machine and to allow vibrations already transmitted to the support tube 25 to subside more quickly.
  • the different thermal expansions of the different materials caused by thermal influence must be taken into account sufficiently. If the support tube 25 is fixed on both sides, thermal stresses would lead to the destruction of the attachment of the support tube 25.
  • the flange 12 ′′ of the section 12 is connected to the flange 23 of the exhaust gas housing 13 of the pressure wave machine 7 by means of a screw connection 29, 30, 31 with the interposition of a seal 33 ′.
  • a temperature surge can also be caused by a brief actuation of the charge air flap 6, the exhaust gas bypass valve 36 or the recirculation flap 37.
  • the charge air flap 6 or the recirculation flap 37 is briefly closed, or when the exhaust gas bypass valve 36 is briefly opened, the charge air density and thus the excess air are briefly reduced, which increases the gas temperature while the fuel injection quantity remains the same.
  • the pressure wave machine 7 tolerates the high temperature peaks because the rotor is flushed with fresh air.
  • the shock wave machine 7's own exhaust gas recirculation capacity can be increased by temperature surges without risk of contamination of the rotor.
