A control system identifies preferred performance information associated with a hydraulic fracturing system; and obtains engine operation information associated with a plurality of engines included in a plurality of respective pump systems of the hydraulic fracturing system. The control system identifies, based on the engine operation information, a set of one or more engines, of the plurality of engines, that are utilizing gaseous fuel and/or that are capable of utilizing gaseous fuel, and obtains methane number information associated with the set of one or more engines. The control system selects, based on the preferred performance information and the methane number information, a set of one or more operation optimization maps, determines, based on the set of one or more operation optimization maps and the engine operation information, control information associated with the plurality of pump systems. The control system controls, based on the control information, the plurality of pump systems.

A control system, apparatus, and method to control load sharing of multiple generator sets of a power supply system are described. Load transient set points to add an individual generator set can include a transient percentage threshold to characterize load transients as a load transient, a transient count threshold, and a transient count time period during which a detected number of load transients is compared with the transient count threshold. A controller can determine whether to add the individual generator set based on whether the detected number of load transients is equal to the transient count threshold within the transient count time period and control addition of the individual generator set responsive to the detected number of load transients equaling the transient count threshold.

System, apparatus, and method for controlling load sharing of generator sets

A vibration reducing system for an engine is disclosed. The vibration reducing system includes at least one pumping member movable through a plurality of pumping strokes during an engine cycle. The vibration reducing system also includes a controller in communication with the at least one pumping member, the controller being configured to identify a vibration characteristic of the engine. The controller also is configured to adjust the displacement of fuel during at least one of the plurality of pumping strokes based on the vibration characteristic.

A condensation dispersion device for use with a power source having an exhaust recirculation system is disclosed. The condensation dispersion device may have a housing with an inlet configured to receive exhaust, and an outlet configured to discharge exhaust. The condensation dispersion device may also have a first static mixing device disposed within the housing and being configured to redirect condensate from an internal wall of the housing into the exhaust.

EGR equipped engine having condensation dispersion device

A condensation reduction device for use with an engine is disclosed. The condensation reduction device may have a first body member configured to receive a flow of exhaust, and a reservoir in fluid communication with the first body member to collect condensate from the flow of exhaust. The condensation reduction device may further have a passageway in fluid communication with the reservoir to direct the collected condensate from the reservoir back into the flow of exhaust.
