Abstract: Apparatus for utilizing heat wasted from an engine includes first pressure detecting means (73) and first temperature detecting means (81) for detecting a pressure and a temperature in a refrigerant passage extending from a condenser (38) to a refrigerant pump (32), second pressure detecting means (72) and second temperature detecting means (82) for detecting a pressure and a temperature in a refrigerant passage extending from a heat exchanger (36) to an expansion device (37), and control means (71) responsive to these four detecting means when operating a Rankine cycle (31). Means (71) is for diagnosing whether or not an electromagnetic clutch (35) is stuck responsive to either the first pressure detecting means (73) and the first temperature detecting means (81), or the second pressure detecting means (72) and the second temperature detecting means (82).

Abstract: To effectively reduce a situation in which an over-rotation of an expander occurs or the expander becomes a load on an engine at the time of a stop of a Rankine cycle in an exhaust heat recovery device provided with the Rankine cycle that recovers exhaust heat of an engine. A pressure difference ΔP between a high-pressure side and a low-pressure side of the Rankine cycle is obtained when the Rankine cycle is stopped (S1), a waiting time Ta is set (calculated) based on the obtained pressure difference ΔP (S2). Then, a bypass valve is opened to allow a refrigerant to circulate while bypassing the expander (S3), and then an electromagnetic clutch is disengaged when the waiting time Ta has elapsed to block transmission of power between the expander and the engine (S4, S5).
