  • Segmented calibration for aftertreatment optimization in internal combustion engine system
    Patent number: 10400700
    Abstract: An internal combustion engine system includes a control system with a monitoring mechanism producing data of engine operating state within a BMEP/speed envelope, and an electronic control unit structured to output a control command to vary at least one of a fuel delivery property or an air delivery property in the engine based on the data. Outputting the control command switches the engine between or among combustion modes that each satisfy different calibration criteria for optimizing aftertreatment function.
    Type: Grant

  • Extended controller keep alive system and method
    Patent number: 7961449
    Abstract: Methods and systems for supplying auxiliary electrical power to a controller during power loss are described hereinabove. The system is powered by a primary power source, and includes a controller and a winding load that are both powered by the primary power source, and a switching device. When the primary power source is disconnected from the controller and winding load, the winding load continues to residually exercise to generate residual electrical power. The second switching device then channels the residual electrical power to the controller for a period of time at an acceptable level.
