The present invention relates to an exhaust gas collector for an exhaust system of an internal combustion engine, in particular in a motor vehicle, having two internal shell bodies which each connect a plurality of inlet openings in a communicating fashion to an outlet opening, having an external shell body which encloses a receptacle space in which the two internal shell bodies are at least partially arranged. In order to improve the response behavior of a turbocharger, which can be connected to the exhaust gas collector, a dividing wall is proposed which divides the receptacle space into two partial spaces, one of the two internal shell bodies being at least partially arranged in each of the partial spaces.

1. An exhaust gas collector for an exhaust system of an internal combustion engine, in particular in a motor vehicle, comprising: two internal shell bodies which each connect a plurality of inlet openings in a communicating fashion to an outlet opening;an external shell body which surrounds a receptacle space in which the two internal shell bodies are at least partially arranged;a dividing wall attached to the external shell body and being a separate component from the external shell body, which divides the receptacle space into two partial spaces; andone of the two internal shell bodies being at least partially arranged in each of the partial spaces. 2. The exhaust gas collector of claim 1, wherein the external shell body has an outlet region in which outlet sections of the two internal shell bodies end with their outlet openings; andwherein the dividing wall extends between the outlet sections, as far as the outlet region. 3. The exhaust gas collector of claim 1, wherein the dividing wall is arranged spaced apart from the internal shell bodies. 4. The exhaust gas collector of claim 1, wherein the external shell body is assembled from two external shells; andwherein the dividing wall is attached to at least one of the external shells. 5. The exhaust gas collector of claim 1, wherein the exhaust gas collector is provided for mounting on a cylinder bank of a four-cylinder series mounted engine or of a V8 engine or of a six-cylinder series mounted engine or of an eight-cylinder series mounted engine or of a V12 engine. 6. The exhaust gas collector of claim 1, wherein the outlet openings of the two internal shell bodies are arranged one next to the other in an outlet region of the external shell body and lie in one plane. 7. The exhaust gas collector of claim 1, wherein the exhaust gas collector is configured as an exhaust gas collector with air gap insulation. 8. The exhaust gas collector of claim 1, wherein the inlet openings are each formed on an inlet section of the respective internal shell body; andwherein the exhaust gas collector has a flange for mounting the exhaust gas collector on the internal combustion engine. 9. The exhaust gas collector of claim 8, wherein the internal shell bodies are permanently connected to the flange in the region of the inlet sections. 10. The exhaust gas collector of claim 8, wherein the external shell body is permanently connected to the internal shell bodies in the region of the inlet sections. 11. The exhaust gas collector of claim 8, wherein the external shell body is permanently connected to the flange in the region of the inlet sections. 12. The exhaust gas collector of claim 8, wherein the external shell body is permanently connected to the internal shell bodies in the region of outlet sections, having the outlet openings, of the internal shell bodies. 13. The exhaust gas collector of claim 1, wherein at least one of the internal shell bodies is configured from a plurality of parts. 14. The exhaust gas collector of claim 1, wherein at least one of the internal shell bodies is configured from a plurality of parts in such a way that at least two components of the respective internal shell body are mounted such that they can move one against the other by means of a sliding fit. 15. An exhaust system for an internal combustion engine, in particular in a motor vehicle: having a twin scroll exhaust gas turbocharger;having an exhaust gas collector as claimed in claim 1 which is attached to the exhaust gas turbocharger; andthe two outlet openings of the internal shell bodies being connected in a communicating fashion to two inlet openings of the exhaust gas turbocharger, which inlet openings lead to a turbine of the exhaust gas turbocharger via separate inlet paths. 16. The exhaust gas collector of claim 1, wherein the dividing wall is positioned within the receptacle space to prevent fluid communication between the two partial spaces. 17. The exhaust system of claim 15, wherein the dividing wall of the exhaust gas collector is positioned within the receptacle space to prevent fluid communication between the two partial spaces. 18. An exhaust gas collector for an exhaust system of an internal combustion engine, in particular in a motor vehicle, comprising: two internal shell bodies which each connect a plurality of inlet openings in a communicating fashion to an outlet opening;an external shell body which encloses a receptacle space in which the two internal shell bodies are at least partially arranged;a dividing wall which completely divides the receptacle space into two partial spaces; andone of the two internal shell bodies being at least partially arranged in each of the partial spaces. 19. An exhaust gas collector for an exhaust system of an internal combustion engine, in particular in a motor vehicle, comprising: two internal shell bodies which each connect a plurality of inlet openings in a communicating fashion to an outlet opening;an external shell body which encloses a receptacle space in which the two internal shell bodies are at least partially arranged;a dividing wall which divides the receptacle space into two partial spaces and is configured so as to prevent fluid communication between the two partial spaces; andone of the two internal shell bodies being at least partially arranged in each of the partial spaces.
