Title: EXHAUST GAS TURBOCHARGER WITH ANNULAR CATALYTIC CONVERTER FOR AN INTERNAL COMBUSTION ENGINE
Abstract:
The invention relates to an exhaust gas turbocharger (1) with an annular catalytic converter for an internal combustion engine, which comprises a radial compressor (30), a rotor bearing (40) having a bearing housing (41) and an exhaust gas turbine (20) having a turbine housing (21). The turbine housing (21) is mechanically fastened to the bearing housing (41) and comprises a turbine exhaust gas pipe (51) for discharging an exhaust gas mass flow (AM) connecting to the turbine outlet (26). A catalytic converter substrate (53) of an annular catalytic converter (50) is arranged on an external circumference if the turbine exhaust gas pipe (51) and a pot-shaped catalytic converter external housing (52) encloses the turbine exhaust gas pipe (51) and the catalytic converter substrate (53) from an exhaust side (57) of the turbine exhaust gas pipe (51) in such a way that an annular passage (54) is formed between the turbine exhaust gas pipe (51) and the catalytic converter external housing (52) in which passage the catalytic converter substrate (53) is arranged. The annular catalytic converter (50) forms an integral unit together with the turbine housing (21).
