Abstract
Abstract: The potential of a cost-based optimization method is experimentally demonstrated
on a Euro-VI heavy-duty diesel engine. Based on the actual engine-aftertreatment state, this
model-based Integrated Emission Management (IEM) strategy minimizes operational (fuel and
AdBlue) costs within emission constraints by real-time computation of optimal air management
set points. This work discusses the control design in detail. By EGR-SCR balancing, fuel
consumption and operational costs are reduced by 2.1% and 1.5%, respectively, compared to
the baseline strategy over the hot World Harmonized Transient Cycle. Due to its adaptation
characteristics, the IEM strategy is robust for varying conditions during real-world operation.
