Methods and systems are provided for controlling a turbine within an internal combustion engine. In one example, a turbine system within an internal combustion engine may include at least one turbine with a housing that may further include at least one impeller mounted on a rotatable shaft, inlet and outlet regions, and at least one overpressure line including a self-controlling valve for controlling the flow of exhaust gas.
