Claim Text:
1. A supercharged internal combustion engine, comprising: at least one cylinder head with at least two cylinders, in which each cylinder has at least one outlet opening for discharging exhaust gases out of the cylinder, and each outlet opening is adjoined by an exhaust line; wherein the at least two cylinders are configured in such a way as to form two groups with in each case at least one cylinder; wherein the exhaust lines of the cylinders of each cylinder group merge in each case to form an overall exhaust line such that an exhaust manifold is formed; wherein the two overall exhaust lines are connected to a two-channel turbine, which comprises a rotor which is mounted on a rotatable shaft in a turbine housing, such that in each case one overall exhaust line is connected to one of two inlet openings of the turbine, wherein each inlet opening is adjoined by one channel of the turbine, wherein the turbine housing comprises a housing wall and a comb-shaped displaceable wall part, the housing wall having a comb-shaped opening upstream of the rotor and downstream of the inlet openings, and wherein the displaceable wall part is displaceable, via a controller, between a first position and a second position, wherein in the first position of the displaceable wall part, the two channels are separated from one another as far as the rotor by the housing wall, such that exhaust-gas streams of the two channels are conducted separate from one another to the rotor, wherein in the second position of the displaceable wall part, the two channels of the turbine are connected to one another within the turbine housing via the comb-shaped opening in the housing wall.
