摘要： An exhaust heat recovery device for an engine including a Rankine cycle, including a steam accumulator that stores a surplus of a working medium for driving a turbine, and a leveling line that discharges the stored surplus working medium from the steam accumulator to the turbine, when the turbine cannot output predetermined power only with the working medium flowing out from a boiler, and levels the power outputted from the turbine. Since the power outputted from the turbine can be leveled without reduction of the power, even if the working medium cannot vaporize with the boiler immediately after start-up, immediately before stop, or during a low-load operation of the engine, exhaust heat from the engine can be efficiently used.

摘要翻译： 一种用于发动机的排气热回收装置，其包括兰金循环，其包括储存用于驱动涡轮的多余的工作介质的蒸汽蓄能器，以及将储存的多余工作介质从蒸汽蓄能器排放到涡轮机的流平线， 涡轮机只能在工作介质从锅炉流出的情况下才能输出预定的功率，并且使从涡轮机输出的功率平稳。 由于从涡轮机输出的功率可以在不降低功率的情况下进行调平，即使工作介质在启动后立即在停止之前或在发动机的低负载运行期间不能与锅炉蒸发， 可以有效地利用发动机。
