    • An engine-waste-heat utilization device includes a Rankine cycle with a heat exchanger that is configured to recover engine-waste-heat to refrigerant, an expander that is configured to generate power using the refrigerant coming out from the heat exchanger, a condenser that is configured to condense the refrigerant coming out from the expander and a refrigerant pump that is configured to supply the refrigerant coming out from the condenser to the heat exchanger by being driven by the expander, a power transmission mechanism (crank pulley, pump pulley, belt) that is configured to transmit surplus power to the engine when the expander has spare power even if the refrigerant pump is driven, a clutch that is configured to connect and disconnecting power transmission by the power transmission mechanism, and a case provided near a high-temperature part of the engine such that a shaft of the expander and that of the refrigerant pump are coaxially arranged, the clutch, the refrigerant pump and the expander are integrally housed in this order and the expander has a higher temperature than the clutch.
    • 发动机废热利用装置包括具有热交换器的兰金循环,所述热交换器构造成将制冷剂中的发动机废热回收,构造成使用从热交换器排出的制冷剂发电的膨胀机,冷凝器 被配置为使从膨胀机排出的制冷剂冷凝;以及制冷剂泵,其被构造成通过由膨胀机驱动从冷凝器供给到热交换器的制冷剂,动力传递机构(曲柄皮带轮,泵皮带轮,皮带 ),即使在制冷剂泵被驱动的情况下,即使膨胀机具有备用电力,也能够将剩余的动力传递给发动机,构成为连接动力传递机构的动力传递的离合器, 发动机的高温部分使得膨胀机和制冷剂泵的轴同轴地布置,离合器,制冷剂泵和 膨胀机以该顺序一体地容纳,并且膨胀机具有比离合器更高的温度。
