Reduced Warm-Up and Recovery of the Exhaust and Coolant Heat with a Single Loop Turbo Steamer Integrated with the Engine Architecture in a Hybrid Electric Vehicle 2013-01-2827
The paper considers a novel waste heat recovery (WHR) system integrated with the engine architecture in a hybrid electric vehicle (HEV) platform. The novel WHR system uses water as the working media and recovers both the internal combustion engine coolant and exhaust energy in a single loop. Results of preliminary simulations show a 6% better fuel economy over the cold start UDDS cycle only considering the better fuel usage with the WHR after the quicker warm-up but neglecting the reduced friction losses for the warmer temperatures over the full cycle.
