An internal combustion engine, comprising: an EGR system containing an EGR gas and including at least one heat exchanger (65, 66) and a thermal control unit, which provides cooling of EGR gas and is positioned downstream from the at least one heat exchanger (65, 66); a WHR (Waste Heat Recovery) system adapted to provide cooling to the EGR gas, the WHR system including a WHR circuit, a fluid cooling and containment portion, a feed pump operable to pump a working fluid from the fluid cooling and containment portion through the WHR circuit, the at least one heat exchanger (65, 66) positioned downstream from the feed pump and operable to convert the working fluid from a liquid to a high-pressure vapor by transferring heat from the EGR gas to the working fluid, an energy conversion portion positioned between the at least one heat exchanger (65, 66) and the fluid cooling and containment portion, the energy conversion portion being capable of producing additional work or transferring energy to another device or system, the thermal control unit being connected to the WHR circuit and being positioned along an EGR temperature control circuit to further cool the EGR gas, and a compressor positioned along the EGR temperature control circuit to pump working fluid from the thermal control unit; at least one sensor positioned along at least one of the EGR system and the WHR circuit, the at least one sensor adapted to generate an output signal; and a control system adapted to receive the output signal and to generate a control signal based on the output signal to control the speed of at least one of the feed pump and the compressor. an EGR system containing an EGR gas and including at least one heat exchanger (65, 66) and a thermal control unit, which provides cooling of EGR gas and is positioned downstream from the at least one heat exchanger (65, 66); a WHR (Waste Heat Recovery) system adapted to provide cooling to the EGR gas, the WHR system including a WHR circuit, a fluid cooling and containment portion, a feed pump operable to pump a working fluid from the fluid cooling and containment portion through the WHR circuit, the at least one heat exchanger (65, 66) positioned downstream from the feed pump and operable to convert the working fluid from a liquid to a high-pressure vapor by transferring heat from the EGR gas to the working fluid, an energy conversion portion positioned between the at least one heat exchanger (65, 66) and the fluid cooling and containment portion, the energy conversion portion being capable of producing additional work or transferring energy to another device or system, the thermal control unit being connected to the WHR circuit and being positioned along an EGR temperature control circuit to further cool the EGR gas, and a compressor positioned along the EGR temperature control circuit to pump working fluid from the thermal control unit; at least one sensor positioned along at least one of the EGR system and the WHR circuit, the at least one sensor adapted to generate an output signal; and a control system adapted to receive the output signal and to generate a control signal based on the output signal to control the speed of at least one of the feed pump and the compressor.
