Abstract
Methods and systems are provided for reducing corrosion of a charge air cooler and preventing engine misfire due to condensate formation. In response to condensate forming in a charge air cooler, engine cooling fan operation is adjusted. Engine cooling fan operation may also be controlled in response to vehicle operating conditions.
Claims23
A method for controlling an engine cooling fan, comprising:
- adjusting engine cooling fan operation in response to condensate formation in a charge air cooler.
A method for controlling an engine cooling fan, comprising:
- adjusting engine cooling fan operation in response to a condensate location in a charge air cooler remaining within a positional range for greater than a threshold duration.
A method for controlling a vehicle engine cooling fan, comprising:
- increasing engine cooling fan speed in response to a condensate-forming location in a charge air cooler, and engine temperature above a threshold or vehicle deceleration conditions;
- and
- decreasing engine cooling fan speed in response to the condensate-forming location, and engine temperature below the threshold.
A method for controlling a vehicle engine cooling fan, comprising:
- adjusting engine cooling fan operation in response to a condensate location in a charge air cooler remaining stagnant for greater than a threshold duration, including increasing engine cooling fan speed in response to a first condition, and decreasing engine cooling fan speed in response to a second condition different from the first condition.
