Abstract: A Rankine cycle waste heat recovery system associated with an internal combustion engine is in a configuration that enables handling of exhaust gas recirculation (EGR) gas by using the energy recovered from a Rankine cycle waste heat recovery system. The system includes a control module for regulating various function of the internal combustion engine and its associated systems along with the Rankine cycle waste heat recovery system.

Abstract: A Rankine cycle waste heat recovery system uses a receiver with a maximum liquid working fluid level lower than the minimum liquid working fluid level of a sub-cooler of the waste heat recovery system. The receiver may have a position that is physically lower than the sub-cooler's position. A valve controls transfer of fluid between several of the components in the waste heat recovery system, especially from the receiver to the sub-cooler. The system may also have an associated control module.
