| 摘要 |
The invention relates to a turbocharger comprising a turbine casing ( 2 ) which has an exhaust-gas inlet opening ( 3 ) and an exhaust-gas outlet opening ( 4 ); comprising a turbine wheel ( 5 ) which is fastened to a shaft ( 6 ) and is arranged in the turbine casing ( 2 ); comprising a plurality of blades ( 7 ; T) which are arranged in the turbine casing ( 2 ) between the exhaust-gas inlet opening ( 3 ) and the turbine wheel ( 5 ), wherein each blade has the following: a profile underside ( 8; 8 ') and a profile top side ( 9; 9 ') which determine the blade thickness, a blade leading edge ( 10; 10 ') at a first intersection of the blade underside ( 8; 8 ') and the blade top side ( 9; 9 '), a blade trailing edge ( 11; 11 ') at a second intersection of the blade underside ( 8; 8 ') and the blade top side ( 9; 9 '), a profile centre line ( 12; 12 ') which is defined by the blade underside ( 8; 8 ') and the blade top side ( 9; 9 ') and runs between them from the blade leading edge ( 10; 11 ') to the blade trailing edge ( 11; 11 '), wherein the profile centre line ( 12; 12 ') runs in a wave-like manner.
