Abstract: A combustion engine system and a method of operating the combustion engine system are disclosed. The combustion engine system includes a first fuel pump operatively coupled to a first prime mover and fluidly coupled to a fuel reservoir, a first power source operatively coupled to the first prime mover, the first power source including a first controller, a third fuel pump having an inlet that is fluidly coupled to a discharge of the first fuel pump, a first filter in fluid communication with the first fuel pump, a combustion engine fluidly coupled to a discharge of the third fuel pump and operative to convert fuel from the third fuel pump into shaft power. The first controller is configured to drive the first prime mover at a substantially constant power, independent of a rate of consumption of the fuel by the combustion engine.
