Theoretical Analysis of Waste Heat Recovery from an Internal Combustion Engine in a Hybrid Vehicle 2006-01-1605
This paper presents a theoretical study of different strategies of waste heat recovery in an internal combustion engine, operating in a hybrid vehicle (spark ignition engine and electric motor). Many of the previous studies of energy recovery from waste heat focused on running thermodynamic cycles with the objective of supplying air-conditioning loads. There are two elements of this study that are different from previous studies: first, the end use of the recovered waste heat is the generation of electric power, and, second, the implementation of these heat recovery strategies takes place in a hybrid vehicle. The constant load conditions for the SI-engine in the hybrid vehicle are a potential advantage for the implementation of a heat recovery system. Three configurations of Rankine cycles were considered: a cycle running with the exhaust gases, a cycle with the engine coolant system, and a combined exhaust-engine coolant system. The development of these strategies indicated the requirements and constraints for each of the configurations, the most appropriate fluids and the geometries and sizes of the components.
