Method and systems for reducing charge air cooler condensate using a secondary intake throttle
Abstract:
Methods and systems are provided for adjusting a secondary intake throttle based on condensate formation in a charge air cooler, the secondary throttle positioned upstream of the charge air cooler. In one example, a method may include decreasing an opening of the secondary intake throttle in response to increased condensate accumulation within the charge air cooler. The method may further include adjusting a primary throttle positioned in an intake manifold based on the condensate accumulation and torque demand.
