  • System and method of fan control
    Patent number: 8160800
    Abstract: A method to operate a vehicle equipped with an electronic controlled internal combustion engine. The engine fan is used as a dynamic fan brake when the vehicle exceeds a minimum predetermined operating parameter for a predetermined period of time, and is disabled once the vehicle is operating within predetermined operating parameters.
    Type: Grant

  • Method of diagnosing a slow EGR system in an internal combustion engine
    Patent number: 8109258
    Abstract: There is disclosed a method for diagnosing slow EGR response in an internal combustion engine equipped with an electronic controller with memory. In one embodiment, the method includes passing an EGR setpoint value and an actual EGR value through first order filters to eliminate high frequency noise; determining an actual EGR gradient as a function of any difference between the EGR set point and the actual EGR value while simultaneously determining an actual EGR gradient; and logging a fault in the electronic controller if the expected EGR gradient is greater than the actual EGR gradient by a predetermined amount.

  • METHOD OF DIAGNOSING A SLOW EGR SYSTEM IN AN INTERNAL COMBUSTION ENGINE
    Publication number: 20110023845
    Abstract: A method for diagnosing slow EGR response in an internal combustion engine equipped with an electronic controller with memory, comprising: determining an actual EGR gradient; determining an expected EGR gradient comparing the expected EGR gradient to the actual EGR gradient determining the expected EGR gradient is greater that the actual EGR gradient and logging a fault in the electronic controller if the expected EGR gradient is greater than the actual EGR gradient, and optionally activating a warning to alert the operator of the logging event.
