Abstract
Various methods and systems are provided for adjusting an amount of intake airflow diverted away from an intake manifold and to atmosphere in response to a temperature of exhaust entering a turbocharger turbine and a target pre-turbine temperature. In one example, an amount of intake airflow entering engine cylinders, and thus an air-fuel ratio entering the engine cylinders, may be controlled to maintain the temperature of exhaust entering the turbocharger turbine at the target pre-turbine temperature.
