Controlling charge air cooler condensation by using heated intake air

摘要

Methods and systems are provided for adjusting the temperature of intake air entering an engine. In response to condensate in a charge air cooler and engine operating conditions, the position of an induction valve is adjusted to draw in air from a warm or cool air duct. Induction valve operation is further controlled to reduce fuel economy losses.
