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.

Abstract: A method for predicating a service life of a fuel filter includes causing a fuel pump of a fuel system to direct fuel through a fuel filter of a fuel system. The method also includes receiving work cycle data from machines that implement a same or similar fuel system. The method further includes receiving, via sensors of the fuel system, fuel system data and determining, from the fuel system data, a pressure difference across the fuel filter. The method further includes determining, based on the work cycle data, predicted load cycle data for the fuel system and determining, via a filter life model, a filter service interval representing an amount of time the fuel filter is operable in the fuel system prior to the pressure difference reaching a predetermined value.
