Abstract
A heat recovery system for an internal combustion engine may include a heat transfer device flowed through by a fluidic heat carrier for transferring the heat from a combustion exhaust gas of the internal combustion engine to the heat carrier, a heat power machine flowed through by the heat carrier for converting the heat transferred to the heat carrier into mechanical work, a substantially cyclically closed duct system for connecting the heat transfer device with the heat power machine, at least one displacement pump for conveying the heat carrier through the duct system in a predetermined flow direction, and a pump drive for driving the displacement pump. A reduced wear may result when the heat recovery system is supplemented by an impermeable separating membrane for the fluid-tight separation of the heat carrier from the pump drive.
