Abstract

A supercharged internal combustion engine wherein a two-channel turbine comprising a shut-off body positioned within a flow transfer duct within a turbine housing fluidly couples the two channels of a turbine housing to one another via the transfer duct responsive to the exhaust gas flow rate to enable better operation of the turbocharger.
