<P>PROBLEM TO BE SOLVED: To provide a waste heat recovery device for internal combustion engine provided with EGR device effective for improving energy efficiency. <P>SOLUTION: The waste heat recovery device 1 for an internal combustion engine is provided with an exhaust gas recirculating passage 13 recirculating part of exhaust gas to an intake air passage between an exhaust gas passage 11 and the intake air passage 12. The waste heat recovery device 1 for the internal combustion engine includes a thermoelectric module 4 provided in an exhaust gas recirculation passage 13 to recover and thermoelectrically convert heat of exhaust gas, a regulator 15 converting electric power generated by the thermoelectric module 4, a storage battery 150 constructed to charging electric power generated by the regulator 15, and a temperature sensor 16 measuring index temperature changing with inking with exhaust gas temperature. The thermoelectric module 4 is constructed to perform thermoelectric power generation when index temperature measured by the temperature sensor 16 is a predetermined threshold value or higher. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
