| 摘要 |
The invention relates to an internal combustion engine (1) comprising a waste-heating recovery system (10), in particularly working according to the organic Rankine cycle, which system comprises at least one compressor (11), at least one heat exchanger (12), at least one expander (13) and at least one condenser (14), wherein an output shaft (5) of the expander (13) can be drivingly connected via a power train (2) comprising at least one shaft coupling (6) to a crankshaft (4) of the internal combustion engine (1), wherein at least one braking device (7) is arranged in the power train (2) between the expander (13) and the internal combustion engine (1). In order to avoid, reliably and with little design effort, an over-speed of the expander (13), the expander (13) can be braked by the brake device (7) if the speed (n2) of the expander (13) exceeds a defined critical limit speed (nk) of the expander (13). |
