Abstract
Methods and systems are provided for adjusting a compressor recirculation valve in response to condensate forming conditions in a charge air cooler (CAC). In one example, a compressor recirculation valve may be opened in response to an induction pressure greater than a threshold pressure when the induction pressure is greater than required to produce a manifold pressure required for a torque demand. Further, a wastegate may be opened to further reduce the induction pressure during certain driving conditions.
