Abstract: Systems and methods for managing power on supplied to a load are provided. In some embodiments, a hybrid power system includes a generator and a power source having an inverter connected to one or more loads. The generator may have a controller that is configured to adjust a parameter (e.g., frequency) of electrical power output via the generator based on a current magnitude of electrical power output of the generator. The inverter is configured to detect the parameter of the electrical power supplied to the load and to adjust a magnitude of current electrical power output based on the detected parameter.

Abstract: Systems and apparatuses include an asynchronous electrical machine coupled to an engine, a power supply selectively coupled to the electrical machine by a power supply switch device, and an electrical output coupled to the electrical machine by an output switch device. The electrical machine is structured to produce electricity when the power supply switch device is open, the output switch device is closed, and the electrical machine is mechanically driven by the engine, or perform as a starter motor to start the engine when the power supply switch device is closed, the output switch device is open, and the electrical machine mechanically drives the engine.

Abstract: A method for controlling a dual fuel engine system includes estimating a total indicated engine load, where the total indicated engine load is based on a sum of a measured engine power and a power loss estimate. The method further includes determining a total fueling amount based on an engine speed and the total indicated engine load, where the total fueling amount includes a gas fueling amount and a diesel fueling amount. The method also includes controlling the dual fuel engine system using the total fueling amount.

Abstract: A genset includes an enclosure and an attenuator assembly coupled to the enclosure. The enclosure defines an at least partially enclosed space and a ventilation air opening. The ventilation air opening fluidly couples the enclosed space with an environment surrounding the enclosure. The attenuator assembly includes a plurality of ducted attenuator panels arranged parallel to one another and parallel to an air flow direction through the enclosure. The plurality of ducted attenuator panels is spaced apart from one another to form a plurality of air passages therebetween. At least one ducted attenuator panel of the plurality of ducted attenuator panels defines a plurality of ducts extending parallel to the air flow direction.

Abstract: A method of product visualization and acoustic noise source localization includes receiving acoustic data that is associated with a first product, mapping a sound field around the first product based on the acoustic data, and generating a 3D surface of the sound data for the first product based on the mapping by at least one of interpolating or extrapolating the sound field. The method further includes generating a simulation of the first product by combining the 3D surface with a visual representation of the first product, and providing, via an emitter, an audio output based on the position of an avatar within the simulation with respect to a position of the first product.

Abstract: Systems and apparatuses include a selective catalytic reduction system structured to receive exhaust gases from a dual fuel engine system and include a diesel exhaust fluid dosing unit, an ammonia slip catalyst positioned directly downstream of the selective catalytic reduction catalyst, an oxidation catalyst positioned directly downstream of the ammonia slip catalyst, and one or more processing circuits. The circuits receive a system out NOx value, a space velocity, an ammonia to NOx ratio, an exhaust temperature, a substitution rate, and a conversion efficiency target. The circuits determine a conversion efficiency differential, adjust the substitution rate based on the system out NOx value, adjust the ammonia to NOx ratio based on the space velocity, the ammonia to NOx ratio, the exhaust temperature, the substitution rate, the conversion efficiency target, and the conversion efficiency differential, and determine a diesel exhaust fluid dosing rate for the diesel exhaust fluid dosing unit.
