Summary:

This paper presents the identification and validation of adynamic Waste Heat Recovery (WHR) system model. Driven by upcomingCO₂ emission targets and increasing fuel costs, engine exhaust gasheat utilization has recently attracted much attention to improvefuel efficiency, especially for heavy-duty automotiveapplications.In this study, we focus on a Euro-VI heavy-duty diesel engine,which is equipped with a Waste Heat Recovery system based on anOrganic Rankine Cycle. The applied model, which combines firstprinciple modeling with stationary component models, covers thetwo-phase flow behavior and the effect of control inputs.Furthermore, it describes the interaction with the engine on bothgas and drivetrain side.Using engine dynamometer measurements, an optimal fit of unknownmodel parameters is determined for stationary operating points.From model validation, it is concluded that the identified modelshows good accuracy in steady-state and can reasonably capture themost important dynamics over a wide range of operating conditions.The resulting real-time model is suitable for model-basedcontrol
