ABSTRACT:
A method for controlling engine operation of an engine having a cylinder receiving fuel from a first and a second fuel injector, the first injector having a first relationship between a first input signal and a first amount of injected fuel, and the second injector having a second relationship between a second input signal and a second amount of injected fuel; the method comprising of varying injection from the first injector into the cylinder, varying injection from the second injector into the cylinder, purging fuel vapors from a fuel system into the cylinder, and adaptively learning said first and second relationships based on sensed operating conditions.
