| 1. A system comprising:
an internal combustion engine including a cooling system,
a heat recovery vapor generator (HRVG) connected to an exhaust of the engine and adapted to utilize heat in exhaust gases
produced by the internal combustion engine to fully vaporize a fully condensed multi-component working fluid stream,
a turbine connected to the HRVG for converting a portion of thermal energy in the fully vaporized multi-component working
fluid stream to a usable form of energy to form a spent multi-component working fluid stream, and
a condensation thermal compression subsystem (CTCSS) connected to the turbine and to the cooling system, where the CTCSS comprises
a plurality of heat exchangers, at least two pumps, a separator, at least one throttle valve, and a plurality of mixing and
combining valves, where the CTCSS is adapted to fully condense the spent multi-component working fluid stream to form the
fully condensed working fluid stream utilizing heat from a cooling system stream, transferring heat between a plurality of
stream comprising three different compositions of the multi-component working fluid and transferring heat to external coolant
streams to form fully condensed streams including the fully condensed multi-component working fluid stream.
