Abstract
A number of variations may include a combustion engine tailpipe exhaust circuit defining an exhaust stream and a waste heat recovery system constructed and arranged to recover thermal energy from at least one of a tailpipe exhaust circuit, exhaust stream, charge air cooler, exhaust gas recirculation fluid stream, or coolant stream. The waste heat recovery system may include an expander assembly that may include a first pump, an expander, an evaporator, and a condenser. A second pump driven by the waste heat recovery system may be in fluid communication with the tailpipe exhaust circuit and exhaust stream and may be constructed and arranged to reduce exhaust pressure in the tailpipe exhaust circuit and exhaust stream. A third pump may be in fluid communication with an exhaust gas recirculation fluid stream and which is constructed and arranged to pump the exhaust gas recirculation fluid stream within the exhaust gas recirculation system.
