EXHAUST GAS TURBOCHARGER FOR AN INTERNAL COMBUSTION ENGINE

摘要

Disclosed is an exhaust gas turbocharger (2) for an internal combustion engine (1), comprising a compressor (5) in the intake pipe system (6) and an exhaust gas turbine (3) in the exhaust gas leg (4). The exhaust gas turbine (3) is provided with an exhaust gas collection chamber located inside a turbine housing (24). The exhaust gas of said exhaust gas collection chamber can be fed to the turbine wheel (27) via a cross section of a turbine inlet. The inventive exhaust gas turbocharger (2) further comprises an exhaust gas by-pass (31) which bridges the cross section of the turbine inlet and connects the exhaust gas collection chamber to a discharge area (28) of the exhaust gas turbine (3). The exhaust gas turbine (3) forms a pump for a gas-feeding device while a gas-feeding conduit (18, 21) that is assigned to the gas-feeding device extends into the exhaust gas by-pass (31).
