Abstract
The present disclosure relates to a method and apparatus to reduce fuel consumption while remaining in NOx compliance by simultaneous and coordinated control of the engine and the selective catalytic reduction (SCR) system. More particularly, the present disclosure identifies methods and apparatus to increase NOx output within a diesel engine to optimize the performance of a given SCR system while simultaneously reducing fuel consumption at a selected and targeted intake oxygen concentration.
