More Information
Summary:An engine assembly comprising an internal combustion engine and a waste heat recovery system, wherein the waste heat recovery system is configured to direct refrigerant around a loop which comprises: a heat exchanger configured to transfer heat from engine exhaust gases to the refrigerant such that the refrigerant is vaporised; a turbine configured to receive and be driven by the vaporised refrigerant; and a condenser configured to cool and condense the refrigerant for subsequent delivery in liquid form to the heat exchanger; wherein the turbine comprises a turbine wheel connected to a shaft which is held in a shaft housing, a bearing lubricated by liquid refrigerant being provided between the shaft and the shaft housing, and wherein squeeze film dampers which utilise the liquid refrigerant are provided between the bearing and the shaft housing.
