Abstract

Methods and systems are provided for de-icing a charge-air cooler of a boosted engine system when the engine is turned off. In one example, a method may include recirculating air through a bypass passage including an activated electric supercharger and the CAC. The air is warmed by compression and thaws ice accumulated in the CAC.
