Abstract
An engine including a WHR system includes a clutch positioned to engage or disengage a WHR feedpump that moves working fluid through a WHR circuit. The clutch engages or disengages the feedpump under certain operating conditions of the engine and/or the WHR system, and/or at the request of an operator of the engine. Conditions may include cool or cold components, and insufficient working fluid. The operator may also request the clutch be disengaged, such as might be advantageous if the operator detects an operational problem with the WHR system or determines there is an advantage to operating the engine without the WHR system.
