Definitions

  • the invention relates to an exhaust gas turbocharger for an internal combustion engine according to the preamble of claim 1.
  • a diffuser emerges in an exhaust gas guide section of an exhaust gas turbocharger for an internal combustion engine.
  • the distributor has a number of adjustable guide vanes which are positioned in an inflow passage in the exhaust guide section, upstream of a wheel chamber in the exhaust guide section, in which the turbine wheel is rotatably received.
  • the distributor has a bearing ring and a contour sleeve, wherein the bearing ring and the contour sleeve are fixed by means of spacer elements such that a certain, first distance between the bearing ring and the contour sleeve is present. Due to the positioning of the spacer elements in the inflow passage of the exhaust gas flow is opposite to a flow resistance, whereby efficiency losses of the exhaust gas turbocharger are brought about.
  • the published patent EP 1 394 364 A1 also discloses a nozzle for an exhaust gas turbocharger, having an exhaust gas guide portion, which has a spiral channel with a spiral tongue, wherein the nozzle assigned to spacer elements.
  • These spacers are aerodynamically designed such that in the inflow of the Abgasanströmung a contrary to the usual known in the prior art spacer elements reduced flow resistance due to the positioning of the spacer elements is realized. Nevertheless, efficiency losses are still due to the positioning of the spacer elements.
  • the invention is based on the object of bringing about a further reduction of efficiency losses, which occur due to the spacer elements positioned in the inflow channel, with the aid of simple measures.
  • the at least one spacer element has a lateral surface whose second distance from a longitudinal axis of the spacer element over a length of the spacer element and / or over a cross-sectional area of the spacer element is variable, wherein the spacer element is positioned in a region of a second wake of the spiral tongue.
  • the outer surface can thereby be designed such that a flow resistance formed on the basis of the spacer element can be reduced, and to increase the efficiency, the spacer element is positioned such that it is arranged in a region of a second caster.
  • a spiral tongue is formed in the exhaust gas guide section. In the region of the spiral tongue, the second wake of the exhaust gas flow is formed when flowing through the spiral channel.
  • the efficiency losses occurring due to the second caster are not or only slightly affected by the positioning of the spacer element in this area.
  • the increase in efficiency is due to the fact that the efficiency losses occurring through the spacer element are compensated by the positioning in the region of the second wake.
  • the cross-sectional area of the spacer element is drop-shaped, similar to a vane cross-sectional area, so that a particularly small flow resistance coefficient can be realized.
  • an embodiment of the spacer element has proven in which a chord length of the spacer element has at least twice the size of a largest profile thickness of the spacer element.
  • the spacer element is to be positioned such that a first wake initiated by the spacer element can be flowed through a channel formed by a first guide vane and a second guide vane adjacent to the first guide vane, without interaction with a boundary layer of the second vane.
  • a flow section which is formed downstream of a flow-around element, can be referred to as a wake.
  • the wake is a flow section formed on the blade trailing edge. This caster leads here to influence the flow in the channel formed between two vanes.
  • the distance between the bearing ring and the contour sleeve is secured over a circumference of the bearing ring.
  • the in Fig. 1 shown istiereströmbare exhaust gas guide portion 2 of an exhaust gas turbocharger 1 is provided in an exhaust tract of an internal combustion engine, not shown, in which it is a gasoline engine or a diesel engine, provided.
  • the exhaust gas turbocharger 1 further includes a non-illustrated throughflow fresh air guide portion and a bearing portion, not shown, which is arranged in a non-illustrated intake tract of the internal combustion engine.
  • the exhaust gas turbocharger 1 has a running gear 3, which is a not-shown compressor wheel for sucking and compressing combustion air, a turbine wheel 4 for expansion of exhaust gas and a compressor wheel with the turbine wheel 4 rotatably connecting shaft 5 with a Rotary axis 6 includes.
  • the shaft 5 is rotatably mounted in the bearing portion of the exhaust gas turbocharger 1, which is positioned between the air guide portion and the exhaust gas guide portion 2.
  • an inlet channel 7 is formed in the exhaust gas guide section 2.
  • the inlet channel 7 is used to condition the exhaust gas, which puts the turbine wheel 4 in a rotating motion during operation of the internal combustion engine.
  • the compressor wheel With the help of the shaft 5, the compressor wheel is also set in rotation, so that it sucks in combustion air and compressed.
  • a spiral channel 8 is arranged in the exhaust gas guide section 2, which serves to provide a rotationally symmetrical flow. Furthermore, the spiral channel 8 is formed as a connecting channel between the inlet channel 7 and an inflow channel 9, which is positioned downstream of the spiral channel 8. At the entry into the spiral channel 8, a spiral tongue 20 is configured in the exhaust gas guide section 2. Downstream of the inflow channel 9, a wheel chamber 10 is arranged in the exhaust gas guide section 2, in which the turbine wheel 4 is rotatably received. Downstream of the wheel chamber 10, the exhaust gas guide section 2 has an outlet channel 11 for the escape of the exhaust gas from the exhaust gas guide section 2.
  • a nozzle 12 is shown according to the prior art.
  • the nozzle 12, the turbine wheel 4 is formed annularly comprehensive and has a bearing ring 13 for receiving guide vanes 14, which are provided for flow conditioning.
  • the guide vanes 14 are rotatably mounted on the bearing ring 13.
  • the bearing ring 13 is positioned in the exhaust gas guide section 2 so that the guide vanes 14 are arranged in the inflow channel 9.
  • the bearing ring 13 is positioned opposite a contour sleeve 15, which is designed for flow conditioning and simplified assembly of the nozzle 12.
  • spacer elements 16 are positioned in the inflow channel 9.
  • spacers 16 according to the prior art are cylindrical.
  • Fig. 3 is shown in a plan view of the nozzle 12 of an exhaust gas turbocharger 1.
  • the spacer elements 16 have a longitudinal axis 17, a lateral surface 18, a length L and a cross-sectional area 19 (see FIG. Fig. 5 ).
  • the spacer elements 16 of the exhaust gas turbocharger 1 according to the invention gem.
  • Fig. 4 are designed aerodynamically, such that the lateral surface 18 has a second distance MA from the longitudinal axis 17, which is variable over the cross-sectional area 19.
  • a preferred cross-sectional area 19 of the spacer element 16 is realized, which has a drop-shaped shape similar to a guide blade cross-sectional area.
  • the cross-sectional area 19 is designed to be consistent along the longitudinal axis 17.
  • the lateral surface 18 could additionally or exclusively over the length L have a variable second distance MA, so that
  • the spacer element 16 has a symmetrical or asymmetrical, waisted or a bulbous contour.
  • a total of three spacer elements 16 are arranged at a third distance RD from the axis of rotation 6, which is greater than a fourth distance RL of the guide vanes 14 from the axis of rotation 6.
  • the spacer elements 16 are preferably formed sleeve-shaped. In a further embodiment, at least four spacer elements 16 are provided.
  • a chord length SL of the spacer element 16 in the exemplary embodiment has approximately four times the size of a largest profile thickness PD of the spacer element 16. To achieve an improvement in efficiency, the chord length SL should be at least twice the size of the profile thickness PD.
  • the spacers 16 are placed relative to the vanes 14 in a streamlined positioning.
  • the positioning is selected such that a first wake 21 initiated by the spacer element 16 can flow through a channel 22 formed by two guide vanes 14 arranged next to one another, ideally in the middle thereof.
