<P>PROBLEM TO BE SOLVED: To provide a waste heat regeneration system 100 capable of promptly stopping a Rankine cycle circuit 30 after stopping an engine 10 while preventing a temperature rise of a high-temperature boiler 34 and working fluid and the runaway of rotating speed of an expander 36. <P>SOLUTION: The waste heat regeneration system 100 includes: the Rankine cycle circuit 30 which includes a pump 32, the high-temperature boiler 34, the expander 36 and a capacitor 38; an expander bypass flow passage 31 which bypasses the expander 36 and has an on-off valve 33; and a control means 60 which circulates, when the operation of the engine 10 is stopped, refrigerant to the expander bypass flow passage 31 with the on-off valve 33 being opened, and also force-feeds refrigerant to the pump 32 at a flow rate larger than in an idling state. <P>COPYRIGHT: (C)2013,JPO&INPIT |
