Integrated energy and emission management for heavy-duty diesel engines with waste heat recovery system
conference paper
Rankine-cycleWasteHeatRecovery (WHR)systems are promising solutions to reduce fuel consumption for trucks. Due to coupling between engine andWHR system, control of these complex systems is challenging. This study presents an integrated energy and emission management strategy for an Euro-VI Diesel engine withWHRsystem. This Integrated Powertrain Control (IPC) strategy optimizes the CO2-NOx trade-off by minimizing online the operational costs associated with fuel and AdBlue consumption. Contrary to other control studies, the proposed control strategy optimizes overall engine-aftertreatment-WHR systemperformance and dealswith emission constraints. Fromsimulations, the potential of this IPC strategy is demonstrated over a World Harmonized Transient Cycle (WHTC) using a highfidelity simulationmodel. These results are compared with a state-of-the-art baseline engine control strategy. By applying the IPC strategy, an additional 2.6%CO2 reduction is achieved compare to the baseline strategy, while meeting the tailpipeNOx emission limit. In addition, the proposed low-levelWHR controller is shown to deal with the cold start challenges.
