  • Generator set exercising system
    Patent number: 10924043
    Abstract: Systems and apparatuses include a control unit structured to communicate with a first generator set, a second generator set, and a third generator set, operate the first generator set as an output generator in an exercise mode, and operate the second generator set and the third generator set as load generators in the exercise mode to use electrical power produced by the first generator set. The second generator set uses a second genset portion of the electrical power and the third generator set uses a third genset portion of the electrical power.
    Type: Grant

  • Genset engine using electrical sensing to control components for optimized performance
    Patent number: 9708950
    Abstract: A genset comprises an engine; an alternator, an exhaust system, a controller, and at least one of an intake system, an EVAP system, a fuel injector, an EGR system, a SAI system and an aftertreatment system. The controller is configured to control at least a portion of the genset. The controller is in electrical communication with one or more of the alternator, the EVAP system, the EGR system, the SAI system and the aftertreatment system via communication circuitry. Furthermore, the controller is configured to: (a) receive an electrical output from the alternator via the communication circuitry, (b) determine a load on the alternator from the electrical output, which corresponds to mechanical load on the engine, and (c) generate an electrical signal configured to at least partially control operation of at least one of the EVAP system, the EGR system, the SAI system and the aftertreatment system via the communication circuitry.
