Abstract:
An exhaust heat recovery system may include an exhaust pipe through which exhaust gas exhausted from an engine moves, a main channel through which a working fluid moves, a turbine rotated by the working fluid exhausted from the main channel to generate energy, an exhaust gas recirculation (EGR) line circulating a portion of the exhaust gas exhausted from the engine to an intake manifold, and channel control valves disposed in the main channel and configured to control movement of the working fluid so that the exhaust gas moving along the EGR line and the working fluid moving along the main channel exchange heat with each other.

Claim (Index 15):
A method of operating an exhaust heat recovery system including a main channel into which a working fluid evaporated through a heat exchanger provided in an exhaust pipe is introduced and a super heater and a turbine that are in selective communication with the main channel through channel control valves provided in the main channel, the super heater heating the working fluid and the turbine generating electric power using the working fluid or the working fluid heated through the super heater, the method comprising:\n driving an engine; and operating the channel control valves so that the main channel and the super heater exchange heat with each other when an EGR valve is operated.
