Abstract
Embodiments for controlling exhaust gas turbines are provided. In one embodiment, a method for controlling a turbocharger arrangement of an internal combustion engine, the turbocharger arrangement having at least a first exhaust-gas turbine and a second exhaust-gas turbine arranged downstream of the first, and an exhaust-gas aftertreatment system being arranged downstream of the second exhaust-gas turbine comprises, in a warm-up mode, controlling at least one exhaust-gas turbine so as to increase an inlet temperature of an exhaust-gas flow at the inlet into the exhaust-gas aftertreatment system. In this way, the exhaust-gas aftertreatment system may be rapidly heated.
