Definitions

  • the invention relates to an internal combustion engine having an internal combustion engine, an exhaust system, a fresh gas train, an exhaust gas turbocharger with a turbine integrated into the exhaust system and a compressor integrated in the fresh gas train, and with a trim plate, by means of which the cross section of the compressor inlet can be changed.
  • the fresh gas supplied via the fresh gas train of the internal combustion engine is compressed.
  • the pressure increase is dependent on the speed of the impeller of the compressor as well as the mass flow of the guided over the impeller fresh gas.
  • the surge limit of the compressor map the inflow of the leading edges of the impeller vanes takes place on the pressure side as a result of the inflow velocity decreasing relative to the peripheral velocity. the incidence of the flow increases steadily. From an operating point-dependent limit value of the incidence, the surge line, the flow at the entry edges triggers and the flow in the compressor becomes unstable.
  • a trim controller is used to shift the surge limit of a compressor map in the direction of low mass flows at high pressure conditions.
  • a trim control can increase the compressor efficiency in the area of the pumping limit.
  • a trim plate comprises a device by means of which the inflow cross-section, in which the impeller of the compressor is impinged, can be changed. Due to the nozzle effect of the trim adjuster achieved in this way, with increasing control engagement (reduction of the inflow cross-section), the compressor inflow can be focused more strongly on the hub-near flow cross-section of the compressor impeller. As a result, less fluid flows into the low-pulse and lossy region of the backflow bubble, and the core flow in the region near the hub is accelerated and thereby additionally stabilized.
  • the acceleration of the flow in the The near-compressor region of the compressor additionally results in a suction-side displacement of the compressor inflow, which can contribute to a further stabilization of the flow.
  • the stabilization of the core flow leads to the desired shift of the surge limit of the compressor map to lower mass flows of the exhaust gas. If not desired control intervention (Trimsteller fully open) as far as possible, the entire cross section of the fresh gas line is released before the compressor, so that in the compressor flow as possible no additional friction or throttle losses.
  • the compressor efficiency and the width of the compressor map are therefore not significantly adversely affected in the direction of Stopfgrenze by the Trimsteller.
  • the dynamic response as well as the partial load operation of supercharged internal combustion engines can be improved. Due to the improved system efficiency, the exhaust back pressure can be lowered in the partial load range, whereby the consumption of the internal combustion engine decreases. Due to the increase in efficiency and the shift of the surge limit, the maximum engine torque can already be achieved at lower engine speeds and thus the transient response of the internal combustion engine can be improved.
  • a generic internal combustion engine is from the DE 10 2010 026 176 A1 known.
  • the trim controller there comprises a cone, which in one embodiment consists of a plurality of lamellae.
  • the lamellae are arranged in two layers, wherein the lamellae of each layer are spaced apart from one another and the two layers are offset in relation to each other in rotation so that the lamellae of one layer cover the distances between the lamellae of the respective other layer.
  • LP-EGR low-pressure exhaust gas recirculation
  • the exhaust gas taken downstream of a turbine of an exhaust-gas turbocharger is introduced via a feed upstream of the compressor of the exhaust-gas turbocharger and drawn in by it with the fresh gas.
  • the introduction of the recirculated exhaust gas should be as close as possible in front of the compressor in order to avoid or keep unwanted condensate formation in the fresh gas.
  • a control valve is usually integrated into the LP EGR introduction prior to compressor entry.
  • Both the supply of the LP EGR and the Trimsteller should function as closely as possible be arranged in front of the impeller of the compressor, resulting in a competing space situation result.
  • the present invention seeks to provide an advantageous way to integrate a LP-EGR in a generic internal combustion engine.
  • ND-EGR low-pressure exhaust gas recirculation
  • the inventive design of an internal combustion engine further advantages can be achieved, as shown below.
  • the integration of the mouth and the design of the trim plate or the cross section of the compressor flow changing element is selected such that by means of the trim setter and the amount of introduced into the fresh gas exhaust gas is controlled or regulated.
  • the movable compressor inflow varying member may preferably be arranged and configured to serve as a control valve or control valve for the LP EGR.
  • This embodiment is in particular advantageously implementable, because the operating ranges of the internal combustion engine, in which a LP EGR is usefully used, regularly correlate with a corresponding operation of the compressor in the vicinity of the surge limit.
  • an increase in the LP EGR rate may correlate with a shift in the operating point of the compressor in the compressor map in the direction of the surge limit, so that it may preferably be provided that the trim plate increases a passage cross section for the exhaust gas as the cross section of the compressor inlet is reduced.
  • the amount of exhaust gas recirculated via the LP EGR can be increased in proportion to the reduction of the inflow section by the trim plate.
  • the trim plate can have a funnel-shaped wall system arranged inside a tubular housing (a section of the fresh gas line), wherein an outlet cross section of the wall system is variable by a more or less spreading of the wall system and wherein the passage cross section for the exhaust gas between the wall system and the housing is formed.
  • the mouth of the LP-EGR can be arranged in the region of the wall system.
  • the wall system may serve as a valve body of an EGR valve for the LP EGR, with the wall system at full spread, i. the largest possible flow cross-section of the compressor impeller, a portion of the housing uses as a valve seat.
  • the wall system may comprise a plurality of first wall elements circumferentially spaced apart from one another annularly and a plurality of second wall elements circumferentially spaced apart from each other in an annular manner, the second wall elements covering the distances between the first wall elements.
  • the trim plate can have an adjusting device (for example, electrically, pneumatically or hydraulically actuated), by means of which the ends of the first and / or second wall elements forming the outlet cross section are in Radial direction are displaced.
  • an adjustable, funnel-shaped wall system can be created in a structurally simple manner, which makes do without the use of highly elastic materials, such as elastomers.
  • the wall elements can thus advantageously be formed from a substantially rigid material and in particular metal (s) (eg steel).
  • the adjusting device may have a position detection, which can confirm the respective position of the wall system to a control electronics (for example engine control) of the internal combustion engine, in order to set a targeted adjustment of the trim adjuster to the operating point of the internal combustion engine.
  • a control electronics for example engine control
  • the wall elements are rotatably mounted on the end forming an inlet cross section of the wall system.
  • the wall elements are mounted rocker-like, so that in a radial, inwardly directed displacement of the outlet cross-section forming ends of these wall elements, the inlet cross-section forming ends of these wall elements are displaced radially outward, resulting in an elastic Bias (at least) connected to a spring element.
  • a rotatable mounting can be realized with a spring action of the wall system in its open position in a simple manner.
  • the wall elements can (at least partially) also be firmly clamped on the end forming the inlet cross section of the wall system, wherein the angular change is absorbed by an elastic deformation of the wall elements. Since the deformation in this case is comparatively small, this can also be achieved with wall elements made of e.g. Metal (s) can be realized. This may optionally account for an additional spring element for acting on the wall system in its open position.
  • the wall elements have a U-shaped cross-section, wherein the ends of the free legs of each first wall element rest on a respective second wall element (and vice versa).
  • the resistance for the sliding relative movement between the first wall elements and the second wall elements can be kept small.
  • this can limit the maximum spread of the wall system.

  • the lengths of the part-circular cross sections of the wall elements 18 decrease continuously, wherein the length reduction of the in the Fig. 1 to 4 Wall element 18 shown above is higher than that of the lower wall element 18.
  • the reduction of the outlet cross section leads to a focus of the fresh gas flowing through the trim plate 12 on the central portion of an impeller 22 of the centrifugal compressor 10 and thus to a reduction of the inflow cross section of the centrifugal compressor 10 in comparison to the fully open position of the trim adjuster 12th
  • the lower wall element 18 also serves as an EGR valve of a LP EGR, which opens into the housing 14 in the region of the wall system 16 of the trim actuator 12.
