Abstract: An example system includes an engine and an exhaust passage fluidly coupled to the engine. A waste heat recovery system includes a boiler operatively coupled to the exhaust passage, and a condenser fluidly coupled to the boiler. An integrated cooling system includes an engine cooling circuit, a waste heat recovery cooling circuit, a waste heat recovery bypass valve, and a controller. The waste heat recovery bypass valve is operatively coupled to the exhaust passage upstream of the boiler, and is selectively controllable so as to direct at least a portion of the exhaust gas through an exhaust bypass passage so as to bypass the boiler. The controller is in operative communication with the waste heat recovery bypass valve. The controller is structured to determine a cooling demand of the engine, and to control a valve position of the waste heat recovery bypass valve based on the cooling demand.
