| 发明名称 | Heat recovery system for an internal combustion engine | ||
| 摘要 | A heat recovery system for an internal combustion engine may include a heat exchanger, through which a fluid heat-transfer medium flows, for transferring heat from an exhaust gas system to the heat-transfer medium. A heat engine, through which the heat-transfer medium flows, may be included for converting the heat transferred to the heat-transfer medium into mechanical output work. A cyclically closed line system may be included for connecting the heat exchanger to the heat engine. The system may include a positive displacement pump for conveying the heat-transfer medium through the line system in a predefined flow direction via mechanical drive work. The system may include a drive, which is hermetically sealed off from the heat-transfer medium, for feeding the drive work to the positive displacement pump, and an output, which is hermetically sealed off from the heat-transfer medium, for discharging the output work from the heat engine. | ||

| 主权项 | 1. A heat recovery system for an internal combustion engine, comprising: a heat exchanger, through which a fluid heat-transfer medium flows, for transferring heat from an exhaust system to the heat-transfer medium, a heat engine, through which the heat-transfer medium flows, for converting the heat transferred to the heat-transfer medium into mechanical output work, a cyclically closed line system for connecting the heat exchanger to the heat engine, a positive displacement pump for conveying the heat-transfer medium through the line system in a predefined flow direction via mechanical drive work, a drive, which is hermetically sealed off from the heat-transfer medium, for feeding the drive work to the positive displacement pump, and an output, which is hermetically sealed off from the heat-transfer medium, for discharging the output work from the heat engine; wherein the heat engine includes an input operatively connected to the output for transmitting the output work to the output, and wherein the heat engine has a fluid-tight wall separating the input from the output, the wall hermetically sealing off the output from the heat-transfer medium. | ||
