METHOD FOR ESTIMATING CHARGE AIR COOLER CONDENSATION STORAGE WITH AN INTAKE OXYGEN SENSOR

摘要

Methods and systems are provided for estimating water storage in a charge air cooler (CAC). In one example, an amount of water accumulating in the CAC may be based on an output of an oxygen sensor positioned downstream of the CAC and ambient humidity. Further, engine actuators may be adjusted to purge condensate from the CAC and/or reduce condensate formation based on the amount of water inside the CAC.
