摘要： 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.

摘要： 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.

摘要： 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.

摘要： Systems and methods for regulating transient deviations in an output voltage of a power generator system are provided. An automatic voltage regulator (AVR) may receive a predictive load signal from a load. The predictive load signal may relate to an anticipated change in the load. The predictive load signal can be configured to include information of the anticipated change in the load. The AVR may extract the information of the anticipated change in the load from the predictive load signal, responsive to receiving the predictive load signal. The AVR may analyze the extracted information to determine whether the anticipated change causes a transient deviation above a predetermined level in the output voltage. The AVR may adjust an excitation current of an alternator prior to detecting a difference between a voltage setpoint and the output voltage, responsive to determining that the anticipated change in the load causes the transient deviation.
