Claim:
1. A supercharged internal combustion engine having at least one cylinder head with at least two cylinders, comprising: each cylinder has at least one outlet opening for discharging the exhaust gases out of the cylinder via an exhaust-gas discharge system, and each outlet opening is adjoined by an exhaust line; at least two cylinders are configured in such a way as to form two groups with in each case at least one cylinder; the exhaust lines of the cylinders of each cylinder group merge in each case to form two overall exhaust lines such that an exhaust manifold is formed in each case; and 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 the two inlet openings of the two-channel turbine, wherein each inlet opening is adjoined by one channel of the two-channel turbine and the two channels are separated from one another as far as the rotor by means of a wall, such that the exhaust-gas streams of the two channels are conducted separate from one another to the rotor; wherein a first group of adjustable guide blades is provided at a rotor-side end of the first channel, and a second group of adjustable guide blades is provided at a rotor-side end of the second channel, wherein the wall is of a modular construction, wherein the wall further comprises a ring which is fixedly connected to the turbine housing and which surrounds the rotor and which forms a rotor-side end of the wall, wherein the ring further comprises circular disks which are rotatably mounted in a flush manner in circular recesses of the ring, and wherein each disk serves to hold at least one guide blade and is rotationally conjointly connected to said guide blade.
