Zusammenfassung:	A method of operating a power system is disclosed. The power system may include an engine. The engine may include a combustion chamber, a drive member, and a fuel system with a fuel injector. The method may include selectively operating the fuel system to supply fuel from the fuel injector to the combustion chamber and combusting the fuel in the combustion chamber to drive the drive member. The method may also include selectively operating the fuel system to generate parasitic losses without supplying fuel to the combustion chamber to drive the drive member. Operating the fuel system to generate parasitic losses may include generating pressure in a component of the fuel system with power derived from the engine and dissipating at least a portion of the generated pressure without delivering fuel from the fuel injector to the combustion chamber.
