Simulation study suggests ORC waste heat recovery system could deliver potential 7% improvement in fuel consumption in a PHEV on highway

Green Car Congress

Starting from a energy-based powertrain simulation model validated on experimental data from the PHEV, the researchers conducted a first- and second-law analysis to identify the potential for engine waste heat recovery, considering a variety of driving cycles and assuming the vehicle operating in charge-sustaining (HEV) mode. Skarke et al.

BMW Study on Rankine Cycle for Waste Heat Recovery Shows Potential Additional 10% Power Output at Highway Speeds

Green Car Congress

In this study, BMW focused on Rankine A (exhaust gas only) and Rankine B (exhaust gas and coolant). BMW is exploring two pathways for waste heat recovery in vehicles: one thermoelectric, the other thermodynamic. System A used exhaust gas only as the heat source; System B used exhaust gas and coolant.
