<P>PROBLEM TO BE SOLVED: To provide an exhaust heat energy recovering system for a hybrid vehicle capable of using a catalyst converter as a stack, being compact, and suppressing heat transmission loss. <P>SOLUTION: The exhaust heat energy recovering system comprises a second catalyst converter 6, a cooling device 10, a resonance pipe 8, control valves V1, V2, and a generating device 9. After stopping the operation of an engine 1, a loop path 20 is formed by the control valves V1, V2. An exhaust gas downstream side end portion of the second catalyst converter 6 is cooled by the cooling device 10, thereby generating a temperature gradient. <P>COPYRIGHT: (C)2008,JPO&INPIT |
