Abstract
The present invention relates to an exhaust system for an internal combustion engine, more preferably of a motor vehicle, with an exhaust gas turbine, with an exhaust pipe, whose inlet is fluidically connected with an outlet of the exhaust gas turbine, with a flange connection for connecting the exhaust gas turbine with the exhaust pipe which comprises a flange fastened to the exhaust pipe and attached to the exhaust gas turbine, and with a shielding apron which is so arranged and/or incorporated in the flange connection that in the operation of the exhaust system it protects a transition region between the flange and the exhaust pipe from direct admission of exhaust gas.
Claims19
An exhaust system for an internal combustion engine, comprising:
- an exhaust gas turbine,
- an exhaust pipe, whose inlet is fluidically connected with an outlet of the exhaust gas turbine,
- a flange connection for connecting the exhaust gas turbine with the exhaust pipe having a flange fastened to the exhaust pipe and attached to the exhaust gas turbine,
- a shielding apron which is arranged and so incorporated in the flange connection that in operation of the exhaust system the shielding apron protects a transition region between the flange and the exhaust pipe against direct admission of exhaust gas
- wherein the shielding apron overlaps the transition region.

- a shielding apron which is arranged and so incorporated in the flange connection that in operation of the exhaust system the shielding apron protects a transition region between the flange and the exhaust pipe against direct admission of exhaust gas;
- wherein the shielding apron
- extends in circumferential direction only along a part circumference of the exhaust pipe;
- and
- wherein the exhaust turbine
- comprises a wastegate valve, wherein the shielding apron only extends along a part circumference of the exhaust pipe in circumferential direction which in operation of the exhaust system is exposed to an exhaust gas onflow which develops with opened wastegate valve.
