  • Method for Injecting Reductant into an Exhaust Gas of an Engine Using an Oscillating Supply Pressures
    Publication number: 20170089243
    Abstract: A method for injecting a reductant into an exhaust gas of a power system. The method includes injecting the reductant at a commanded flow rate, while simultaneously oscillating a supply pressure of the reductant between a higher supply pressure and a lower supply pressure.

  • VARIABLE GEOMETRY TURBOCHARGER CONTROL SYSTEM
    Publication number: 20140363278
    Abstract: The disclosure relates to a control system for a turbo-charged engine having a variable geometry turbine driving a compressor. An intake manifold temperature sensor senses an intake manifold temperature. An intake manifold pressure sensor senses an intake manifold pressure. A turbine inlet temperature sensor senses a turbine inlet temperature. A turbine inlet pressure sensor senses a turbine inlet pressure. A control unit generates a vane position control signal which is applied to a vane control input of the turbine. The control unit generates the vane position control signal as a function of turbine inlet temperature and turbine inlet pressure.
