Abstract
Methods and systems are provided for providing auxiliary heat to a charge air cooler to reduce condensate formation. A coolant valve may control the delivery of heated engine coolant to the inlet side of the charge air cooler. The coolant valve may be adjusted based on condensate formation in the charge air cooler and a temperature at the charge air cooler outlet.
Claims20
An engine method, comprising:
- adjusting heating to a charge air inlet side of a charge air cooler in response to an operating condition.
An engine method, comprising:
- increasing a flow of engine coolant to a charge air inlet side of a charge air cooler responsive to increased potential for condensate formation during engine coolant temperature above a threshold coolant temperature;
- and
- not increasing the flow of engine coolant to the charge air inlet side of the charge air cooler during engine coolant temperature below the threshold coolant temperature.
An engine method, comprising:
- during a first condition, including when condensate formation is greater than a threshold and charge air cooler outlet temperature is less than a threshold temperature, adjusting a coolant valve to deliver heated engine coolant to a charge air inlet side of a charge air cooler and;
- during a second condition, different from the first, closing the coolant valve to stop delivery of heated engine coolant to the charge air inlet side of the charge air cooler.
