Abstract
Apparatus for utilizing heat wasted from an engine includes: a Rankine cycle (); a transmission mechanism that couples an output shaft of an expansion device () to a rotary shaft of an engine via an electromagnetic clutch () that can be engaged and disengaged; a passage () through which refrigerant exiting a heat exchanger () flows so as to bypass the expansion device (); and a bypass valve () interposed in the passage. To stop the expansion device (), the electromagnetic clutch () is switched from an engaged state to a disengaged state after switching the bypass valve () from a closed state to an open state. If the bypass valve () becomes stuck in the closed state, expansion device front-rear differential pressure limiting processing in which a front-rear differential pressure of the expansion device is limited while maintaining the electromagnetic clutch () in the engaged state is performed.
