Abstract
A method for controlling the power of an engine is provided. The method includes determining a baseline fuel amount, determining an engine cooling fan operating condition based on an engine operating parameter, determining an engine cooling fan command based on the engine cooling fan operating condition, determining an engine cooling fan power level based on the engine speed and the engine cooling fan command, determining an additional fuel amount based on the engine cooling fan power level, adding the additional fuel amount to the baseline fuel amount to create a compensated fuel amount, and providing the compensated fuel amount to the engine. An engine system, including an engine controller coupled to an engine, a fuel system and a hydraulic pump, is also provided. The engine controller includes a processor adapted to perform a set of instructions that controls the power of the engine.
