Definitions
- the invention relates to an exhaust gas turbocharger for an internal combustion engine according to Features of the preamble of claim 1.
- a radial turbine for an exhaust gas turbocharger is known from DE 37 24 385 C2, whose inlet channel for the exhaust gases is spiral.
- the curved Inlet geometry can be straight and tangential to the turbine housing aligned inlet duct a compact, the restrictive package requirements modern passenger car meets the overall geometry of the exhaust gas turbocharger become.
- the curved intake duct geometry harbors disadvantages with regard to the Flow distribution of the exhaust gas entering the turbine; in addition, the Geometry for an increased wall flow in the so-called tongue area, the is called in the transition area of the inlet duct into the turbine space, which leads to a leads to additional thermal or mechanical stress.
- the object of the invention is therefore, despite a curved inlet channel for the Turbine housing has the same thermodynamic properties as an exhaust gas turbocharger to achieve that with a straight and tangential to the turbine housing aligned inlet channel is provided.
- the gas flow in the inlet area of the turbine Exhaust gas turbocharger positively influenced, in particular by the inflowing exhaust gas Channel center is directed. This can minimize the flow losses that Flow of the turbine wheel blades improved and the thermodynamic Efficiency of the turbine or the exhaust gas turbocharger can be increased overall. About that is also achieved by the flow deflection that in the tongue area of the Turbine housing provided wall sections are thermally less stressed.
- the flow deflection is easily done by one at the Ramp-like projection provided on the inner channel wall of the inlet channel.
- This hill-like projection is advantageously in the inner wall of the Inlet channel integrated and can thus in a common manufacturing step be produced together with the turbine housing.
- the projection is provided immediately in front to arrange the neck cross-section of the inlet duct.
- the exhaust gas turbocharger essentially consists of a turbine housing 2, a Bearing housing 4 and a compressor housing 6. This takes place in the bearing housing 4 Trolley (not shown) for the turbine wheel 8 arranged in the turbine housing 2 and for the compressor wheel (not shown) arranged in the compressor housing 6 Admission.
- a flange provided on the housing of the exhaust gas turbocharger 10
- the exhaust gas turbocharger can on an exhaust manifold of an internal combustion engine be attached.
- On the exhaust gas turbocharger there is also a fastening bolt 12 provided exhaust flange 14 recognizable by the in the installed state advanced exhaust system is attached.
- On the compressor housing 6 is still a Air outlet 16 recognizable through which the compressed intake air Internal combustion engine is supplied.
- the boost pressure of the exhaust gas turbocharger can be regulated.
- the inlet duct 22 leading to the turbine space 20 is of spiral design.
- a so-called neck cross section Q H is formed between the duct inner wall 24 and the duct outer wall 26.
- a hill-like projection 28 protruding into the inlet channel 22 is formed in the channel inner wall 24.
- This projection 28 which tapers the channel cross section, is formed in one piece from the channel inner wall 24.
- This spoiler-like projection 28 deflects or deflects the exhaust gas flow flowing into the inlet channel 22 toward the center of the channel.
