Title: Method of determining distribution of vapors in the intake manifold of a banked engine

Abstract: A method is provided for accommodating the purge vapors from an evaporative emission control system of an automotive vehicle. The method includes a means of learning the bank-to-bank distribution of purge vapors within the engine manifold. As such, the fuel to air ratio delivered from various injectors can be selectively controlled to accommodate the purge vapor at that bank of the engine and maintain the desired fuel to air ratio.
