Definitions
- the invention relates to an internal combustion engine with an internal combustion engine, a
- Exhaust line a fresh gas train, an exhaust gas turbocharger with a turbine integrated into the exhaust line and a compressor integrated in the fresh gas train, and with a trim plate, through which the cross section of the compressor inlet is variable.
- the fresh gas supplied via the fresh gas train of the internal combustion engine is compressed.
- 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 intervention (reduction of the inflow cross section), the compressor inflow can be influenced more strongly by the flow cross section of the impeller close to the hub
- Compressor flow result, which can contribute to a further stabilization of the flow.
- the stabilization of the core flow leads to the desired displacement of the
- Compressor efficiency by means of a Trimstellers the dynamic response and 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.

- 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 before the compressor entry. Both the supply line of the LP EGR and the Trimsteller should function as closely as possible be arranged in front of the impeller of the compressor, which is a competing

- Low pressure exhaust gas recirculation (ND-EGR), through the exhaust gas downstream of the turbine taken from the exhaust line and upstream of the compressor in the fresh gas train can be introduced, wherein (at least) a mouth of the LP-EGR in the region of the Trimstellers, i. in the same section of the fresh gas train as the Trimsteller or the cross section of
- Compressor inflow changing element of the trim adjuster is arranged.
- the integration of the mouth and the design of the Trimstellers or the cross section of the compressor flow changing element is selected such that by means of the Trimstellers 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 be associated with a shift in the operating point of the compressor
- Compressor map correlate in the direction of the surge limit, so that it may preferably be provided that the Trimsteller in a reduction of the cross-section of the
- Compressor current increase a passage cross-section for the exhaust gas.
- 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 trim adjuster can assume the function of an EGR valve, a separate EGR valve can be provided. This can be particularly advantageous if a control of the LP EGR independent of the trim actuator or of its influence on the EGR feedback rate is to be achieved.
- the wall system may have a plurality of first
- the trim plate can have an adjusting device (eg, 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 Verstelivoriques may have a position detection, which can avoid the respective position of the wall system to a control electronics (for example, engine control) of the internal combustion engine 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 outwards, 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) at the the inlet cross section of the
- Wallsystems forming end also be firmly clamped, the angle 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. As a result, if necessary, an additional spring element for
- 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).
- Wall elements are kept small. In addition, this can limit the maximum spread of the wall system.
- a preferred because structurally simple embodiment of the adjusting device may comprise an adjusting ring with one or more guide grooves, wherein the first and / or second wall elements are guided in the guide grooves, that a rotation of the adjusting ring to a radial displacement of the outlet cross-section forming ends of the first and / or second wall elements leads.

At these ends, both wall elements 18 have a substantially semicircular cross-section. In the direction of the downstream end, the lengths of the part-circular cross-sections of the wall elements 18 decrease continuously, the
- Length reduction of the wall element 18 shown in FIGS. 1 to 4 above is higher than that of the lower wall element 18. This allows the upper wall member 18 to be submerged in the lower wall member 18 (see Figure 4) when the wall members 18 are pivoted inwardly by means of an adjustment device, not shown, whereby the free, downstream ends are radially (with respect to the longitudinal axis 20 of the trimmer ) move inwards.
- an adjustment device not shown
- the free, downstream ends are radially (with respect to the longitudinal axis 20 of the trimmer ) move inwards.
- 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.
