Abstract: A generator set configured to provide an electrical output to an external electrical load. The generator set includes an engine configured to drive an electric generator, the engine including an engine block, where the electric generator is configured to couple to the external electrical load. The generator set includes a heating system in fluid communication with the engine block, the heating system including an electric fluid heater, where the electric jacket fluid includes a resistive load configured to supplement the external electrical load. The generator set includes a control system for: monitoring a first parameter of the engine; generating a first control signal in response to the first parameter being less than a first threshold; and increasing the external electrical load by turning on the electric fluid heater in response to the first control signal.

Abstract: Electric devices of a vehicle are divided into groups according to a magnitude of electric power used by each of the electric devices. The number of the groups is smaller than the number of the electric devices. A controller for the vehicle stores in advance different correction amounts respectively associated with the groups. The controller is configured to, when the number of operating ones of the electric devices belonging to the same group is equal to or greater than a predetermined specified number, perform an increase process of increasing an engine rotation speed of an internal combustion engine by the correction amount associated with the group in which the number of the operating ones of the electric devices is equal to or greater than the specified number.

Abstract: A hydrogen fueled powerplant including an internal combustion engine that drives a motor-generator, and has a two-stage turbocharger, for an aircraft. A control system controls the operation of the motor-generator to maintain the engine at a speed selected based on controlling the engine equivalence ratio. The control system controls an afterburner, an intercooler and an aftercooler to maximize powerplant efficiency. The afterburner also adds power to the turbochargers during high-altitude restarts. The turbochargers also include motor-generators that extract excess power from the exhaust.

Abstract: A fuel selector for use with a dual fuel generator includes a selector plate, a first fuel valve assembly positioned adjacent the selector plate and actuatable between an ON position and an OFF position to selectively control a first fuel flow to an engine of the dual fuel generator, and a second fuel valve assembly positioned adjacent the selector plate and actuatable between an ON position and an OFF position to selectively control a second fuel flow to the engine of the dual fuel generator. A selector switch coupled to the selector plate is linearly translatable from a first position to a second position, so as to enable positioning of only one of the first fuel valve assembly and the second fuel valve assembly in the ON position at a given time, such that the first and second fuel valve assemblies cannot be in the ON position concurrently.

Abstract: A method that may include obtaining environmental parameters related to one or more routes of a trip for a first vehicle system, and determining one or more expenditure sections and one or more charging sections of the one or more routes by predicting where the first vehicle system will consume energy and where the first vehicle system will generate the energy, respectively, during the trip based on the environmental parameters. A first trip plan may be obtained for the trip based on the one or more expenditure sections and the one or more charging sections, the trip plan designating one or more operational settings for the first vehicle system for travel during the trip.

Abstract: A generator set for a transport climate control unit is provided that is operable at a first frequency and a second frequency. The generator set includes a generator, a prime mover configured to operate at a first non-zero speed and a second non-zero speed that is less than the first non-zero speed, and a genset controller configured to control operation of the generator set. When operating at the first non-zero speed, the genset controller is configured to monitor a prime mover load parameter to determine whether the prime mover is approaching or has exceeded an overload or stall situation. The genset controller is configured to reduce the speed of the prime mover from the first non-zero speed to the second non-zero speed to prevent the overload or stall situation.

Abstract: A system for supplementing a fixed fuel source for an engine includes a motor-generator set connected to a mechanical load device and a controller. The motor-generator set includes a motor and a generator. The engine is configured to provide a first torque from a fixed fuel source from an independent variable flow input. The fixed fuel source is independent of the engine and set external to the engine. The mechanical load device is driven by the engine and configured to require a second torque defined by an independent flow device. The controller is configured to compare the first torque and the second torque, provide a first control signal to the motor to provide power to the engine when the second torque exceeds the first torque and provide a second control signal to the generator to draw power from the engine when the first torque exceeds the second torque.
