  • Locomotive engine emission control and power compensation
    Patent number: 7165400
    Abstract: A method and apparatus for lowering NOx in diesel engine exhaust gases while maintaining thermal efficiency, by retarding the start of fuel injection, increasing the compression ratio, and reducing the turbocharger inlet flow area to increase turbocharger speed and inlet manifold boost levels for the engine intake air.
    Type: Grant
    Filed: December 15, 2004
    Date of Patent: January 23, 2007
    Assignee: General Electric Company

  • Locomotive engine restart shutdown override system and method
    Publication number: 20050027411
    Abstract: A system for overriding an EMD locomotive engine protective device which includes a low water pressure sensing device in communication with the engine cooling system for shutting down the engine when low water pressure in the engine is sensed, the override system comprising a water assist pump connected to a source of water and communicating with the protective device for supplying pressurized water to the low water pressure sensing device to maintain relatively high water pressure to prevent the device from shutting down the engine; and a controller for activating the water assist pump during start up of the engine.
