A system for controlling condensation associated with a vehicle engine air supply includes a shutter assembly 50 selectively allowing airflow, eg having a plurality of movable shutter members 52. An air supply cooler, eg intercooler 36, is situated near the shutter assembly 50 such that air flowing through the shutter assembly is incident on an exterior of the air supply cooler 36. A controller 54 determines when at least one condition exists that is conducive to condensation within the air supply cooler 36 and controls the shutter assembly 50 to alter an amount of air incident on the exterior of the cooler for controlling condensation in the cooler, eg to maintain the temperature of the intake air at or above a condensation threshold temperature. Conditions conducive to condensation may be determined by sensing the temperature and pressure of the ambient air and the temperature of the air exiting the cooler 36. Operation of the windscreen wipers may be taken to indicate that there is moisture in the ambient air which would increase the cooling capacity of the cooler 36 and thus contribute to condensation formation. |
