To reduce reduction of engine efficiency due to increase of exhaust pressure of the engine.SOLUTION: In a halfway of an exhaust pipe 5, a waste heat collection path 52 on which an evaporator 31 of a heat pipe system 3 is installed, and a bypass path 53 which detours the waste heat collection path 52 are connected in parallel. A branch part 51a of the waste heat collection path 52 and the bypass path 53 on the exhaust pipe 5 comprises an on-off valve 55 for opening and closing the waste heat collection path 52, and a confluent part 51b of the waste heat collection path 52 and the bypass path 53 on the exhaust pipe 5 has a switch valve 56 for switching communication to the exhaust pipe 5 between the waste heat collection path 52 and the bypass path 53. The switch valve 56 is an exhaust pressure sensitive valve for opening the bypass path 53 for communicating the same to the exhaust pipe 5 when a pressure of the exhaust gas G becomes equal to or greater than a prescribed value, when the bypass path 53 is being closed and the exhaust pipe 5 is being communicated to the waste heat collection path 52.SELECTED DRAWING: Figure 2

    【課題】エンジンの排気圧の上昇によるエンジン効率の低下を低減させる。【解決手段】排気管5の途中に、ヒートパイプシステム3の蒸発器31が設置された排熱回収路52と、排熱回収路52を迂回するバイパス路53とを並列に配置する。排気管5における排熱回収路52とバイパス路53との分岐部51aに排熱回収路52を開閉する開閉弁55を設け、排気管5における排熱回収路52とバイパス路53との合流部51bに、排気管5への連通を排熱回収路52およびバイパス路53との間で切り替える切替弁56を設ける。切替弁56は、バイパス路53を閉じて排気管5を排熱回収路52に連通させている際に、排ガスGの圧力が所定値以上になると、バイパス路53を開放して排気管5とを連通させる排圧感応弁である。【選択図】図2
