METHODS AND SYSTEMS FOR INCREASING AIRFLOW THROUGH A CHARGE AIR COOLER TO DECREASE CHARGE AIR COOLER CONDENSATE

摘要

Methods and systems are provided for increasing airflow through a charge air cooler (CAC) in order to purge condensate from the CAC. In one example, a method includes increasing airflow through the CAC while maintaining torque by selectively deactivating one or more engine cylinders and increasing boost. The number of deactivated cylinders may be based on an amount of condensate within the CAC.

1. A method for an engine, comprising:
transiently increasing airflow through a charge air cooler (CAC) of the engine by opening a compressor bypass valve; while maintaining engine torque by increasing boost pressure by closing a turbocharger wastegate.
