Supercharged internal combustion engine with twin-flow turbine and method for operating an internal combustion engine of said type

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 an overall exhaust line such that an exhaust manifold is formed, 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 an 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;
• and
• wherein a first group of adjustable guide blades is provided at the rotor-side end of the first channel, and a second group of adjustable guide blades is provided at the rotor-side end of the second channel.
