Abstract
A method for adjusting an air-fuel ratio of a turbocharged engine that operates without blow though and with blow through is disclosed. In one example, the method provides a way to provide a feed forward fuel adjustment in the presence of engine blow though so that a closed loop controller does not have to exceed its range of control authority.
