摘要
A method of accelerating warming of components of a vehicle (10, Fig. 1) following engine ignition, the vehicle (10, Fig. 1) comprising an engine 12, an energy recovery system 16, and a coolant circuit 31 that delivers coolant fluid to the energy recovery system 16 for transfer of thermal energy to the coolant fluid, and to each component; the method comprising operating the energy recovery system 16 in a low recovery mode, in which the amount of thermal energy that is converted in to work is reduced relative to a normal recovery mode, during a warm-up period each component, corresponding to a time period during which each component warms to a normal operating temperature following ignition, to increase a rate of transfer of thermal energy recovered from the exhaust gas to coolant fluid in the coolant circuit 31. The energy recovery system may comprise a turbine 21 and compressor 22 that are coupled.
