Abstract
A device includes an exhaust gas turbocharger and an annular catalytic converter, which is mounted downstream of the turbocharger in the flow direction, wherein the annular catalytic converter has a first tubular flow section, a deflecting region, and a second annular flow section, wherein the tubular flow section is formed by an inner tube, and the annular flow section is formed between an outer tube, running substantially parallel to the inner tube, and the inner tube, and the deflecting region is designed to deflect the exhaust gas flow out of the tubular flow section into the annular flow section, wherein the tubular flow section of the annular catalytic converter comprises the same components as the gas outlet of the turbocharger mounted upstream in the flow direction.
Claims12
A device comprising:
- an exhaust gas turbocharger;
- an annular catalytic converter which is mounted downstream of the exhaust gas turbocharger in a flow direction, wherein the annular catalytic converter has:
- a first tubular flow section formed by an inner tube, configured as an input to the annular catalytic converter and arranged at a first longitudinal end of the annular catalytic converter;
- a second annular flow section formed between an outer tube, running substantially parallel to the inner tube;
- a deflecting region configured to deflect an exhaust gas flow out of the first tubular flow section into the second annular flow section;
- and
- a heater configured as a heating disc formed by a honeycomb body and arranged in the inner tube;
- wherein the first tubular flow section of the annular catalytic converter forms a gas outlet of the exhaust gas turbocharger mounted upstream in the flow direction.
