  • 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
    Filed: December 19, 2007
    Date of Patent: April 17, 2012
    Assignee: Detroit Diesel Corporation
    Inventors: Jeffery S. Hawkins, Todd C. Slater, Charles C. Blake, Miguel Menoyo-Alonso, Darren P. Aherne, Matthew T. Baird

  • System for diagnosing operation of a cooling system for an internal combustion engine
    Patent number: 6925376
    Abstract: A system for diagnosing operation of a cooling system for an internal combustion engine includes a coolant temperature sensor producing a temperature signal corresponding to coolant fluid temperature, means for determining either an engine load or a throttle percentage, and a control computer configured to diagnose operation of the cooling system as a function of the temperature signal, either the engine load or throttle percentage, and a fuel delivery command for controllably supplying fuel to the engine. After expiration of a diagnostic period, the control computer diagnoses the cooling system as normally operating if the diagnostic period ended by the temperature signal meeting or exceeding a predefined temperature and if a total energy used by the engine during the diagnostic period is less than an estimated energy, and diagnoses the cooling system as failing if the total energy used during the diagnostic period otherwise meets or exceeds the estimated energy.
