  • Injector having tangentially oriented purge line
    Patent number: 8499739
    Abstract: A fluid injector for an exhaust treatment device is disclosed. The fluid injector may have a housing at least partially forming a fluid chamber. The housing may have a central axis, and a fluid passageway configured to supply fluid to the fluid chamber. The supply of fluid may be in a tangential direction relative to the central axis.
    Type: Grant

    Date of Patent: August 6, 2013
    Assignee: Caterpillar Inc.
    Inventors: Glenn Brian Cox, Stephen Michael Wiley, Alan R. Stockner, Thomas Randall McClure, Xiaohui Gong, Qiang Chen, Robert Lowell Miller
  • Fluid injector having purge heater
    Patent number: 8484947
    Abstract: A fluid injector for an exhaust treatment system is disclosed. The fluid injector may have a body, a pin member, and a heater. The pin member may be disposed within the body and have a fluid receiving end and a fluid injecting end. The heater may be disposed about the fluid injecting end of the pin member.

  • Power source braking system to prevent engine stalls
    Patent number: 7926464
    Abstract: A system to prevent engine stalls for a machine having a power source is disclosed. The power source is in communication with a controller, which is configured to determine the temperature of the power source and compare the temperature of the power source to a predetermined threshold temperature. The controller is configured to disable power source braking if the temperature of the power source is less than the threshold temperature. The controller is further configured to determine the power source speed and the travel speed of the machine, and disable power source braking if the power source speed and machine travel speed are less than predetermined thresholds.

  • Turbocharger system implementing real time speed limiting
    Publication number: 20090133399
    Abstract: A turbocharger system for use with an engine having a braking mode of operation is disclosed. The turbocharger system may have a turbocharger with variable geometry, and a sensor situated to generate a signal indicative of a turbocharger speed. The turbocharger system may also have a controller in communication with the turbocharger and the sensor. The controller may be configured to vary the geometry of the turbocharger during the engine's braking mode of operation to increase a backpressure of the engine. The controller may also be configured to vary the geometry of the turbocharger to reduce the backpressure when the signal indicates a speed of the turbocharger within an amount of a desired speed.
