ENGINE-WASTE-HEAT RECOVERY DEVICE

WIPO Patent Application WO/2014/103820

A1

This engine-waste-heat recovery device is equipped with: a radiator for cooling an engine-cooling fluid; a Rankine cycle system which includes a heat exchanger for recovering waste heat from the engine in a coolant, an expander for generating power by using the coolant, a condenser for condensing the coolant, and a coolant pump for supplying the coolant to the heat exchanger, and has the condenser and the radiator positioned in order from the upstream side in the direction of airflow; and a drive mechanism for driving the coolant pump. The waste-heat recovery device is further equipped with one of the following: an operation-region-limiting means for limiting an engine operation region when a coolant pump abnormality is produced in the non-operation region of the Rankine system; an engine-maximum-output-limiting means for limiting the maximum output of the engine when a coolant pump abnormality is produced in the non-operation region of the Rankine system; and a maximum-vehicle-speed-limiting means for limiting the maximum vehicle speed of a vehicle when a coolant pump abnormality is produced in the non-operation region of the Rankine system.
