摘要 |
The invention relates to a drive system for motor vehicles comprising a waste heat-producing internal combustion engine (10) and a circuit for draining off at least partially said waste heat with a working fluid which is relievable in an expansion machine (38), wherein said working fluid comprises several components, wherein at least one component is transferable into a gas phase by absorbing heat of the internal combustion engine and/or another source inside the drive system which also comprises means (34) for separating the liquid fraction from the working fluid prior to the expansion machine pressure removal. The internal combustion engine can be cooled by a first cooling circuit. A second cooling circuit can be used in such a way that the first cooling circuit is cooled thereby. |
