Abstract

In an exhaust gas turbocharger for an internal combustion engine with a turbine casing including a turbine inlet structure with two flow passages separated by a partition, a turbine control valve is arranged in the partition and is in communication with a turbine bypass flow passage, which is disposed in the partition and extends to the turbine outlet for discharging exhaust gases from at least one of the two turbine inlet flow passages to the turbine outlet under the control of the turbine bypass valve.
