NOVELTY - The system (10) has a loop (20) including fluid, a conduit (34o), heat exchangers (24, 40) and a valve (36), where one of the heat exchangers conducts heat energy between the fluid and an exhaust gas recovery system (14), and the other heat exchanger conducts heat energy between the fluid and an exhaust (16). Another loop (22) creating electric power includes another conduit (34i), a third heat exchanger (44) and a turbine (58), where the third heat exchanger transfers heat from the recovery system to another fluid. A fourth heat exchanger (52) transfers heat between the loops.    USE - Waste heat recovery system for a diesel engine.    ADVANTAGE - The three-way valve allows desired amount of engine exhaust gas to flow through the conduit, thus allowing the system to better control the amount of heat from the engine exhaust that is passed to the fluid flowing through the loop by way of the heat exchanger. The three-way valve directs the gas flowing through the engine exhaust into the conduit and allowing the gas to bypass the heat exchanger, thus preventing heat transfer into stagnant fluid present within the heat exchanger. The valve is opened to increase fluid flow through the inner loop and ensure the fluid within loop reaches a desired temperature when an exhaust gas recirculation system is in lower flow state, so that increase in the temperature of the fluid within the conduit allows additional heat to be transferred through the heat exchanger and into the fluid within the conduit so as to ensure that the fluid within conduit enters the turbine at maximum desired temperature.    DETAILED DESCRIPTION - The fluid of the second loop is organic fluid such as butane or pentane.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a waste heat recovery system.
