    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.

    Abstract: A genset enclosure includes a frame system, a plurality of side panels, a plurality of roof panels, a first connector, and a second connector. The frame system includes a plurality of interconnected frame members. The plurality of side panels are coupled to opposing sides of the frame system. The plurality of roof panels are coupled to a roof of the frame system and extend between the opposing sides of the frame system. The plurality of roof panels are oriented perpendicular to the plurality of side panels. The frame system, the plurality of side panels, and the plurality of roof panels together define an enclosure portion having a first open end and a second open end. The first connector and second connector are engageable with one another and are coupled to the frame system along a perimeter of the first open end and the second open end, respectively.

    Abstract: Generally, an overflow conduit is described in apparatuses, systems, and methods to protect a crankcase oil sump from overfill. The overflow conduit is to be connected to a crankcase oil sump of an engine, and is configured to passively receive oil from the crankcase oil sump to avoid an overfill condition from occurring in the crankcase oil sump. The overflow conduit is configured to deliver excess oil received to a sub-base tank located relatively below the crankcase oil sump, or in particular at or below an oil level in the crankcase oil sump.

    Abstract: A modular skid base is provided for supporting, for example, a power generation system that includes a prime mover (e.g., an engine) and a driven machine (e.g., an alternator; a generator; a compressor; a pump; a gear drive for, for example, heavy industrial applications; or any other type of load device). The modular skid base includes a pair of first support skid rails and a pair of second support skid rails. The modular skid base also includes an overlapping section that includes a portion of the second support skid rails overlapping a portion of the first support skid rails along a length direction of the modular skid base. The overlapping section can provide stiffness where required without adding height and mass to the entire modular skid base.

    Abstract: A method for energy control can include receiving an operating point of an energy conversion device at a telematics interface of a data processing system, the telematics interface configured to receive information from the energy conversion device. The method can include generating, by the data processing system, a digital twin of the energy conversion device, the digital twin having a virtual operating point. The method can include predicting, by the data processing system, a future load associated with the energy conversion device. The method can include modeling a predicted response to the future load based on the digital twin, the predicted response corresponding to the virtual operating point. The method can include conveying, to the energy conversion device via the telematics interface, an adjustment to the operating point of the energy conversion device based on the predicted response to the future load.

    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.
