METHOD FOR ESTIMATING CHARGE AIR COOLER CONDENSATION STORAGE AND/OR RELEASE 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 in charge air exiting the CAC may be based on an output of an oxygen sensor positioned downstream of the CAC. Further, engine actuators may be adjusted to increase combustion stability and/or reduce condensate formation based on the amount of water exiting the CAC.
