ABSTRACT:
The present invention provides a method of compensating for a boil-off condition in a flexible fuel compensation control system for a flexible fueled vehicle with a PCV solenoid. The methodology determines both the presence and extent of boil-off corruption and handles closed loop controls normally as if no boil-off corruption exists. The methodology also determines the amount of boil-off corruption being introduced through the PCV system and updates the flexible fueled vehicle fueling during a blend change between ethanol and gasoline. Additionally, the methodology determines when boil-off corruption is no longer influencing closed loop fuel control.
