Abstract
This study presents an integrated energy and emission management strategy for an Euro-VI diesel engine with Waste Heat Recovery (WHR) system. This Integrated Powertrain Control (IPC) strategy optimizes the CO2-NOx trade-off by minimizing the operational costs associated with fuel and AdBlue consumption. The main contribution of this work is that the effect of tailpipe emissions and WHR dynamics are included in the control design. In a simulation study, the potential of this strategy is demonstrated over a World Harmonized Transient Cycle. These results are compared with a baseline engine control strategy. This study shows that slow WHR dynamics strongly affect the engine performance: neglecting these dynamics in the control design leads to unacceptable high tailpipe NOx emissions. By applying the IPC strategy, an additional 2.8% CO2 reduction is achieved within the NOx emission limit compared to the baseline strategy.
