摘要： One embodiment is a system comprising an internal combustion engine including an output shaft, a pulley system structured to be driven by the output shaft, a first alternator and a second alternator structured to be driven by the pulley system, and an electromagnetic clutch integrated within one of the pulley system, the first alternator and the second alternator and structured to selectably couple and decouple at least one of the first alternator and the second alternator from the output shaft. The system includes a controller in operative communication with the internal combustion engine system and structured to evaluate power demand and power production capability parameters of the system and to control the electromagnetic clutch to engage or disengage in response to the evaluation.

摘要： A connector block that directs fuel from an outer fuel line to an inner fuel line. The connector block includes an inlet that couples to the outer fuel line, an outlet that coupled to the inner fuel line, and a fuel accumulator fluidly coupled to the inlet and the outlet. The fuel accumulator directs the fuel from the inlet to the outlet.

摘要： A modular system for injecting fuel into an engine comprises a fuel rail coupled to the engine. A plurality of connection members are coupled to the fuel rail, and each of the plurality of connection members is configured to receive fuel from the fuel rail. The fuel is directed to a plurality of fuel injectors, and the plurality of fuel injectors are configured to direct fuel to a plurality of cylinders. A plurality of outer fuel lines are coupled to the plurality of connection members, and the plurality of outer fuel lines are arranged in a single configuration. The single configuration allows the fuel rail to be coupled to a plurality of engine configurations while maintaining the plurality of outer fuel lines arranged in the single configuration.
