Abstract: Control of an internal combustion engine system in response to a condensation condition associated with a charge air cooler is disclosed. One or more operating parameters of the internal combustion engine are monitored to the control charge air cooler coolant inlet temperature to keep the charge temperature above the estimated dew point to reduce or prevent condensation upstream of the intake manifold.
