Definitions
- the invention relates to an exhaust gas turbocharger for an internal combustion engine according to the preamble of claim 1.
- turbocharger comprises an exhaust gas turbine, which in a turbine housing has a turbine wheel which is to be driven by the exhaust gases of the internal combustion engine.
- the exhaust gas is supplied to the turbine wheel via a plurality of spiral channels, which guide the exhaust gas to the turbine wheel via a respective radial flow inlet cross-section.
- DE 42 42 494 Cl embodiments are described with two, three and four spiral channels, each of which radial flow inlet cross sections are assigned distributed in different angular intervals over the circumference of the turbine wheel.
- each flow inlet cross-section is a guide grid, which allows a defined flow of the turbine wheel with adjustable swirl and volume flow.
- a guide grille with a narrow flow cross section can be used to generate a high back pressure.
- a guide grid with a larger flow cross-section may be provided in order to enable a largely throttle-free exhaust gas flow to the turbine wheel, in particular during partial load operation of the internal combustion engine.
- the different baffles are arranged on a common, sleeve-shaped flow control.
- the Strömungsleitapparat is designed to be axially displaceable, which closed-formed, continuous or interruption-free wall sections of the Strömungsleitapparates can be inserted into individual flow inlet cross-sections and the effective flow area can be reduced accordingly.
- the flow conditions in the case of a guide grille which is only partially exposed and an inlet cross section partially closed by the wall of the flow control device can deteriorate significantly, which in particular impairs the efficiency of the exhaust gas turbocharger.
- the flow control device is usually either placed in a position in which the flow inlet cross section is completely closed or in a position in which the guide grid extends over the entire axial width of the flow inlet cross section.
- the invention is based on the problem to provide with simple structural measures additional adjustment options for a generic exhaust gas turbocharger.
- intermediate positions at the axial width of the flow inlet cross-section to the turbine wheel should be infinitely adjustable without impairing the flow conditions.
- the guide-grid ring is held between two walls which delimit the flow-inlet cross-section axially, one of the walls a- xial is carried out slidably and has a receiving opening into which the guide grid is to be pushed or pushed out during an axial movement of this wall. Due to the axial displacement of the movable wall, the axial width of the flow inlet cross sections can be adjusted. In contrast to the state of the art, any intermediate positions are possible without affecting the flow conditions in the turbine flow, since in each position of the axially displaceable wall, the guide grid is effective in the free, effective flow inlet cross section with its defined guide grid geometry influencing the flow.
- sliding wall can be adjusted by the variation of the axial position of the wall of the optimal for each operating point of the engine radial Str ⁇ mungseintrittsquerites without thereby affecting the arrangement of the turbine wheel negative.
- the depth of the receiving opening on the displaceable wall is advantageously adapted to the axial extent of the guide grid, so that the guide grid can be inserted into the receiving opening until the radial flow inlet cross-section is closed and the flow inlet cross-section is completely closed or except for a residual gap.
- an exhaust turbine designed as a combination turbine which also has a semi-axial flow inlet cross-section in addition to the radial flow inlet cross-section, a complete decoupling from the semi-axial inlet cross-section is possible when the radial inlet cross-sections are closed.
- the combination turbine can thereby be reduced to an axial turbine in certain operating states of the internal combustion engine. the, whereby an increase in efficiency is possible.
- the exhaust gas turbocharger described can be used both in four-cylinder internal combustion engines and in six-cylinder internal combustion engines.
- the exhaust gases of the two middle cylinders are advantageously summarized and fed to a spiral channel and summarized in the same way the exhaust gases of the outer cylinder and fed to the second spiral channel.
- two spiral channels can also be provided, wherein each three cylinders arranged one behind the other are each connected to a spiral channel.
- a separate charge for driving the turbine wheel can advantageously be utilized by the separate combination of the exhaust gases of individual cylinders of the internal combustion engine.
- a high proportion of the kinetic energy can be utilized by passing a pre-charge pressure pulse over the respective spiral channel onto the turbine wheel when opening the exhaust valves.
- FIG. 1 shows a section through an exhaust gas turbine of an exhaust gas turbocharger for an internal combustion engine, with a radial and a semi-axial Str ⁇ mungseintritts- cross section to the turbine wheel, wherein in the radial flow inlet cross section, a guide grid is designed with an axially displaceable wall,

- the exhaust gas turbine 1 has two separately executed spiral channels 4 and 5, which communicate with the exhaust gas line of the internal combustion engine and can be supplied to the turbine wheel 3 via the exhaust gas of the internal combustion engine.
- Each spiral channel 4, 5 is expediently connected via separate exhaust gas lines to a respective part of the cylinders of the internal combustion engine, so that only the exhaust gas of the relevant cylinder is introduced into the respective spiral channel 4 or 5. This makes it possible to exploit in certain operating states of the internal combustion engine, a supercharger to increase the performance of the exhaust gas turbine.
- the two spiral channels 4 and 5 are advantageously carried out mutually almost str ⁇ mungs- or pressure-tight and each have a radial flow inlet cross-section 6 and 7 and a semi-axial flow inlet cross-section 8 and 9, via which the exhaust gas from the spiral channels 4 and 5 impinges on the turbine wheel 3 and this drives.
- the rotational movement of the turbine wheel 3 about the longitudinal loader axis 12 is transmitted via a shaft 13 to the compressor wheel in the exhaust gas turbocharger. After hitting the turbine wheel 3, the exhaust gas flows axially from the exhaust gas turbine 1 via an outflow channel 14.
- the first spiral channel 4 is assigned a radial flow inlet cross section 6 and a semi-axial flow inlet cross section 8.
- the second spiral channel 5 is assigned a radial flow inlet cross-section 7 and a semi-axial flow inlet cross-section 9.
- the flow inlet cross sections of each spiral channel extend in each case over an angular range of 180 ° about the turbine wheel 3rd

- the displaceable wall 16 has on its side facing the housing 15 fixed side one or a plurality of receiving openings 18 which extend over the circumference of the wall 16 and extend in the axial direction.
- These receiving openings 18 are used in an axial approximation of the sliding wall 16 to the housing-fixed wall 15 for receiving the Leitgitterringes 10 and the vanes of the Leitgitterringes 10. In this way it is possible to reduce the distance between the walls 15 and 16 so far that both walls 15 and 16 are in contact with each other and the radial flow inlet cross-sections 6 and 7 are completely closed or up to a remaining gap. This allows the combination turbine to be reduced to a semi-axial turbine. About the insertion of the radial Leitgitterringes 10 in the receiving openings 18, the radial flow inlet cross sections 6 and 7 are continuously adjusted. In order to ensure an optimum flow onto the radial guide-grid ring 10 and the turbine wheel 3, regardless of the axial position of the adjustable wall 16, the adjustable bare wall 16 on its radially outer side a streamlined contour.
