Definitions

  • the invention relates to an exhaust gas turbocharger for an internal combustion engine, with an exhaust gas turbine and a compressor, as well as with an upstream of the impeller of the exhaust gas turbine axially displaceably arranged in the housing locking slide for controlling the flow, wherein the locking slide has recesses for vanes of the exhaust gas turbine, wherein at least one group of Guide vanes is covered in at least one locking position of the locking slide, wherein the locking slide has at least one flow channel whose cross-section, regardless of the position of the locking slide establishes a flow connection between an inlet spiral and the impeller.
  • the exhaust gas turbine has an axially displaceably arranged in the housing locking slide for controlling the flow.
  • the locking slide has recesses for the guide vanes of the exhaust gas turbine in order to cover the guide vanes in at least one blocking position of the locking slide. It is provided that flow channels remain in the blocking position between the housing and the gate valve to establish a flow connection between the inlet spiral and the impeller.
  • the DE 100 52 555 A1 describes an actively controllable charging system for internal combustion engines with a twin-flow exhaust gas turbine, wherein a first flood is separated from a second flood by a partition and wherein the flow through one of the two floods can be blocked by a gate valve.
  • the object of the invention is to avoid these disadvantages and to increase the turbine efficiency, especially in the partial load range.
  • the exhaust gas turbine has two groups of vanes, wherein guide vanes whose channel cross sections are variable by the gate valve, have a larger radial component, as guide vanes whose Leitschaufelkanalqueritese are unchangeable, preferably the flow channel in the course and in cross section about a corresponds to the guide vane channel spanned by adjacent guide vanes.
  • the blocking slide has a plurality of flow channels, preferably distributed uniformly over the circumference.
  • the impeller of the exhaust turbine Movable Water-driven turbine
  • the impeller of the exhaust turbine Movable Water-driven turbine
  • an inner flood is separated from an outer flood by a rotationally symmetrical partition and the flow through at least one of the two floods can be blocked by the gate valve, preferably yourself partition between an entrance and an exit area of the impeller extends.
  • the flow channels of the locking slide are directed in the blocking position only on one of the floods of the impeller.
  • the gate valve is mechanically or electrically coupled to a preferably formed by a slider control member of the compressor, so that the gate valve of the exhaust turbine and the control member of the Compressor are synchronously movable.
  • the Fig. 1 and Fig. 2 show an exhaust gas turbine 1 of an exhaust gas turbocharger 2 with a housing 3, in which a single-flow impeller 4 is rotatably arranged.
  • Reference numeral 5 designates the inlet spiral.
  • a guide ring 7 is arranged between the entrance spiral 5 and the inlet 6 in the impeller 4, a guide ring 7 is arranged.
  • the guide vane channels 7b are formed, whose cross-section is variable by a in the direction of the axis of rotation 4 'of the impeller 4 sliding gate valve 8.
  • Fig. 1 shows the locking slide 8 in its open position and Fig. 2 the locking slide 8 in its closed position.
  • the locking slide 8 has recesses 8a for the guide vanes 7a, so that the locking slide 8 with the recesses 8a can be pushed over the guide vanes 7a. As a result, the corresponding guide vane channels 7b are reduced or closed in their cross-section.
  • the locking slide 8 also has flow channels 8b distributed uniformly over the circumference, whose cross sections essentially correspond to the guide vanes channels 7b. These flow channels 8b having a radial component and a tangential component do not cause any guide vane channels 7b to be reduced or closed when the locking slide 8 is in the closed position, but instead individual guide vane channels 7b remain open for a defined minimum flow rate irrespective of the position of the locking slide 8.
  • the sum of the always remaining non-controllable vane channels 7b or the sum of the flow channels 8b is approximately one third of the sum of the total cross sections of the vane channels 7b. Due to the defined minimum flow rate, a reduction in the rotational speed, in particular the idling rotational speed, is avoided when adjusting the locking slide 8.
  • FIG. 3 to FIG. 5 show a variant in which the impeller 40 is formed Moflutig and an inner flood 41 and an outer flood 42, wherein the two floods 41, 42 are separated by a rotationally symmetrical partition 43 from each other.
  • the partition wall 43 extends from the inlet region 6 out of the housing 3 to the outlet region 9 of the impeller 40.
  • Fig. 3 shows the locking slide 8 in an open position
  • Fig. 4 the locking slide 8 in an intermediate position
  • Fig. 5 the locking slide 8 in a blocking position.
  • At the in Fig. 3 illustrated open position of the locking slide 8 are both floods 41, 42 of the impeller 40 released completely.
  • the inner flood 41 is at least partially closed.
  • the outer flood 42 remains unthrottled.
  • a defined minimum flow rate into the inner flood 41 can be ensured by flow channels 8b of the blocking slide 8. If the locking slide 8 in the in Fig. 5 brought shown blocking position, so both floods 41, 42 are at least partially closed, whereby also here a defined minimum flow rate can be provided by means of the flow channels 8b of the locking slide 8.
  • this may consist of a ceramic material.
  • the compressor has control elements for flow control, wherein the locking slide 8 of the exhaust turbine 1 and the control elements of the not shown synchronously can be operated.
