Claim Text:
1. An engine system comprising: an engine, said engine having a cooling system, said cooling system being adapted to absorb a quantity of waste heat from said engine to produce a first high temperature gas phase of a coolant and a second high temperature liquid phase of said coolant; a first subsystem, said first subsystem including a converter and a condenser, said converter being adapted to receive said first high temperature gas phase of said coolant and to produce mechanical energy and a third low temperature gas phase of said coolant, said condenser being adapted to receive said low temperature gas phase of said coolant and to extract heat to produce a fourth high temperature liquid phase of said coolant; a second subsystem, said second subsystem being adapted to receive said second high temperature liquid phase of said coolant; a heat exchanger, said heat exchanger being adapted to receive said second high temperature phase of said coolant and said fourth high temperature phase of said coolant, and to extract heat to produce a fifth low temperature phase of said coolant; a valve system, said valve system being coupled to said first and second subsystems, said valve system being adapted to control a flow of said second and fourth high temperature liquid phases of said coolant to said heat exchanger according to an operational state of said engine, such that said heat exchanger forms an exclusive return path upstream of said engine and downstream of said valve system for said second high temperature phase and said fourth high temperature phase of said coolant.
