A method for operating an internal combustion engine having a waste heat utilization device including a waste heat utilization cycle in which a valve mechanism, an evaporator, and an expander are arranged, may include adjusting the valve mechanism between an evaporator position and a bypass position via a control/regulating device as a function of at least one operating parameter of the internal combustion engine. The method may also include calculating at least one of a power and an energy generatable by the waste heat utilization device via the control/regulating device as a function of the at least one operating parameter of the internal combustion engine. The method may further include switching the expander between an active state and an inactive state via the control/regulating device as a function of the at least one of the calculated power and the calculated energy.
