Definitions
- the invention relates to an exhaust gas turbocharger for an internal combustion engine Combustion according to the preamble of claim 1.
- EP 0 196 183 B shows a turbocharger in which the flow cross section can also be changed.
- the uneven application of the circumferential direction Impeller added which causes a one-sided mechanical load on the bearing.
- the same applies to a solution as disclosed in US 4,512,714 A. is.
- DE 197 17 559 A describes a turbocharger with two flows are alternately exposed to exhaust gas, with one flood surrounding the other and is connected to it via openings.
- Such a turbocharger is due the flow losses and the premature expansion of the exhaust gas unsatisfactory efficiency.
- DE 42 42 494 C also shows an adjustable flow guide for the Impeller of an exhaust gas turbocharger that can be switched via various floods can be formed, can be flowed to. It can thus be achieved that the Exhaust gas turbocharger is optimally operated in wide areas of the engine map. However, if individual floods are blocked off, the impeller becomes asymmetrical flowed to, which leads to an increased bearing load and a loss of efficiency leads.
- the object of the invention is to avoid these disadvantages and an exhaust gas turbocharger to create one in a wide range of operating conditions has good efficiency.
- an exhaust gas turbocharger to create one in a wide range of operating conditions has good efficiency.
- Internal combustion engine to achieve the greatest possible power on the turbine, a quick response and a favorable torque curve to reach. It should be a strength solution and a long lifespan can be achieved.
- this is achieved in that the nozzles of a first group are arranged at even angular intervals around the impeller and that between these nozzles, further nozzles are provided which are designed to be controllable are.
- the solution according to the invention ensures that in all operating states a centrally symmetrical flow to the impeller is guaranteed, which results in a correspondingly low bearing load, so that a long service life is achieved.
- the inflow cross-section can optimally match the respective Exhaust gas flow can be adjusted, but always the optimal flow technology Flow conditions up to the turbine wheel inlet are given. In particular all nozzles always show the optimal, i.e. generally minimal Distance to the impeller.
- the guide device consists of at least two Groups of nozzles exist that are directly on the outer circumference of the impeller are directed, and that the volute is divided into at least two floods each of which is in flow communication with a group of nozzles stands, and that further a switching device is provided to individual or all floods of the volute with the internal combustion engine on the exhaust gas side connect to.
- the nozzles are through fixed guide vanes educated. This makes a particularly simple, fluidically advantageous Construction reached. Since the guide device has no moving parts, one is such a solution is particularly robust and in particular for use in commercial vehicles suitable.
- a particularly good adaptation of the turbocharger to the respective operating condition the internal combustion engine can be achieved in that the first Group of nozzles, the second group and any other groups a different one Have number of nozzles.
- the nozzles of the first group, the nozzles of the second Group and the nozzles of any other groups a different width in Have circumferential direction.
- a particularly simple construction of the invention is characterized in that that the switching device by a motor-operated Flap is formed.
- the width of the nozzles is circumferential at least the circumferential distance of the blades of the impeller equivalent.
- electromotive support of the turbine is provided.
- an electric motor directly into the connection between the impeller and the turbine be integrated.
- the guide device has a plurality of fixed nozzles, which are immediate are directed to the outer periphery of the impeller, as well as several pivoting guide vanes, which are arranged around the impeller and which in can be brought into a position in which the volute almost exclusively through the fixed nozzles are in flow connection with the impeller.
- This Solution stands out compared to known turbochargers with variable turbine geometry characterized by the fact that even with a small gas throughput optimal flow conditions are given for the impeller, because the nozzles in terms of distance to the impeller, the flow angle and the cross-sectional area are optimized. This allows the internal combustion engine to operate even at low speeds high turbine speeds and thus high boost pressures can be achieved. With higher gas throughput, the guide vanes are opened to allow larger flow cross-sections to reach.
- a further preferred embodiment variant looks downstream of the switching device in the area of a flood a blow-off valve in front of the predetermined pressure in the flood opens. This ensures that additional to the possible power levels of the turbine by switching the individual Floods are given, an additional stage for highest exhaust gas flows is created the blow-off valve, the so-called waste gate, is opened is. Therefore, it is not necessary to set the turbine to the highest possible exhaust gas flow to be designed, so that with a somewhat smaller turbine found the sufficiency can be. This enables an additional improvement in the response behavior and the possibility of a finer gradation of the turbine performance.
- a particular advantage is that only a partial flow of the exhaust gas is influenced by the waste gate.
- each corresponding Impact sectors of the impeller e.g. a situation with kick-down achieved that the flood with waste gate through the switching device is not applied, and in the other flood or the other floods higher exhaust gas pressure can be achieved than the opening pressure of the waste gate pretends.
- the switching device has a predetermined position, in the high Gas throughput the pressure in both floods is approximately the same.
- Position of the switching device can be by a catch or a preprogrammed Setting must be specified.
- the blow-off device When the blow-off device is closed the switching device is in a central position when there is a high gas throughput, to apply both floods evenly.
- the blow off device i.e. the waste gate opens, it is advantageous to slightly favor the gas flows to redirect the flood in which the waste gate is located. To this Even with the waste gate open, even application can occur the turbine can be guaranteed.
- the exhaust gas turbocharger generally has a turbine 1, which also has a shaft 2 is connected to a compressor 3 and drives it.
- a Impeller 4 is provided, which has a guide device 5, which consists of guide vanes 6 exists, with the exhaust gas of an internal combustion engine, not shown becomes. After flowing through the impeller 4, the exhaust gas flows in one axial opening 7 from.
- the exhaust gas becomes a guide device via a spiral housing 8 5 guided, in which two floods 9, 10 arranged side by side in the axial direction are separated from each other by a partition 14.
- the turbine 1 is connected upstream of an adapter 21 which, in addition to the flap 13, has a relief valve 20 records.
- This relief valve 20 is shown as a flap valve that as mechanically actuated or as electromagnetic actuated by the engine control Valve can be executed. It is also possible in a known way Way to provide mechanical control over the boost pressure, or simply use a pressure relief valve.
- the gas flow from the blow-off valve 20 opens into an exhaust pipe 22 downstream of the turbine 1.
- FIG. 2 It can be seen from FIG. 2 that a total of nine stationary guide blades 6 are arranged at uniform angular intervals around the impeller 4, so that 6 nozzles 11, 12 are formed between these guide vanes, which on the Impeller 4 are directed.
- the nozzles 11 of the first group stand with the first Flood 9 in fluid communication.
- the impeller 4 depending on the operating state the internal combustion engine via three nozzles 11 of the first group, over six Nozzles 12 of the second group or applied to all nine nozzles 11, 12 become. This allows a high speed even with a low exhaust gas flow the impeller 4 and thus a favorable boost pressure and a quick response can be achieved.
- control ratio 1: 2: 3 can be changed as required, for example can that between the nozzles 11 of the first group, for example three nozzles 12 of the second group can be arranged.
- width of each Nozzles are designed differently in the circumferential direction. It is essential that all guide blades 6 have an optimal gap width s to the outer circumference of the impeller 4.
- a motor-driven flap 13 can be seen schematically from FIG. 3, with which the exhaust gas flow in the first flood 9 or in the second flood 10 or in the Middle position in both floods 9, 10 can be steered.
- 3 is with solid lines show a position of the flap 13 in which the exhaust gas flow into the first flood 9 to act on the first group of nozzles 11 is set.
- Another position is shown with broken lines, in the the exhaust gas flow into the second flood 10 to act on the second group of Nozzles 12 is directed.
- the flap 13 can be arranged directly in the housing of the turbine 1 be, also be provided in a special adapter housing that to the flue gas turbocharger according to the invention is flanged or in the exhaust manifold of the internal combustion engine.
- the upstream side of the flap 13 is in two Channels 15, 16 divided into different groups of not shown Guide cylinders of the internal combustion engine.
- the two channels 15, 16 are combined in the first flood 9.
- the channels 15, 16 are separated from one another with the Floods 9, 10 connected, which additionally has a gas dynamic effect double-flow turbine housings can be used.
- FIG. 5 essentially corresponds to FIG. 3, but with the flap 13 in is shown in a position in which it is at the highest exhaust gas flow and open Blow-off valve is located.
- the exhaust gas flow becomes the first flood 9 somewhat throttled and an additional exhaust gas stream redirected to the second flood 10. Downstream of the waste gate, which is not shown in FIG. 5, therefore results approximately a uniform pressure level in both floods 9, 10.
- FIG. 6 shows an embodiment in which the locking body 30 is in the axial direction can be inserted into the first nozzles 11 in order to largely close them.
- the strength of the engine braking effect can also be continuously adjusted by that the blocking bodies 30 are immersed at different depths in the nozzles 11.
- An optimal engine braking effect is achieved when the switching device 13 directs the entire exhaust gas flow onto the first nozzles 11 and thus the nozzles 12 switches off the second group. In this way, the relief valve 20 deactivated.
- Turbine 7 has a Turbine 1, which is connected via a shaft 2 to a compressor, not shown and drives it.
- An impeller 4 is provided in the turbine 1, that via a guide device 5, which consists of pivotable guide vanes 6, with the exhaust gas of an internal combustion engine, not shown.
- a total of twelve guide blades 6 are provided, arranged in groups of three blades around the impeller 4 are.
- Nozzles 11 are arranged between the individual groups of guide blades 6, which are formed from fixed guide vanes 6a.
- volute casing 8 In the position of the pivoting guide vanes drawn with solid lines 6, the volute casing 8 is only connected to the impeller 4 via the nozzles 11 in connection, since the guide blades seal against one another and at the nozzles 11 issue.
- the impeller 4 is therefore flowed only through the nozzles 11, the radial gap s and the inflow angle are optimized.
- With higher gas throughput are the pivotable guide vanes 6 simultaneously or one after the other opened, as shown partly by broken lines, to one to provide the corresponding flow cross-section.
- the present invention makes it possible, even at low engine speeds and thus a low exhaust gas flow a high turbine speed and thus a good one To achieve responsiveness and optimal charging.
