  • Patent number: 8527183
    Abstract: A controller, in electrical communication with the one or more of the injectors and a high-pressure fuel pump, generates a first signal responsive to which the valve in the injector opens or closes and a second signal responsive to which the high-pressure fuel pump increases or decreases the pressure level in the fuel accumulator. The system may also include one or more sensors to detect a pressure within the air manifold and to detect the pressure within the fuel accumulator. The controller is programmed to calculate an in-cylinder gas pressure. When the engine is operating at a maximum engine load and the in-cylinder gas pressure reaches or exceeds a maximum pressure limit, the controller transmits one or more signals to adjust the fuel injection timing and/or adjust the pressure in the fuel accumulator to maintain NOx and fuel consumption within acceptable limits.

  • Patent number: 8494696
    Abstract: A method is provided including determining a first power level required from a diesel powered system. The first power level corresponds to a first proportion of a maximum power. The method also includes determining an emission output for a mission based on the first power level. The method further includes determining a second power level corresponding to a second proportion of the maximum power, wherein alternate use of the second power level and at least one of the first power level or a third power level results in a lower emission output for the mission, with the overall resulting power being proximate the minimum power required. The method also includes automatically controlling operation of the diesel powered system by using the second power level alternately with at least one of the first power level or the third power level.

  • Patent number: 8468809
    Abstract: A system is provided for removing particulate matter from a particulate filter. The system includes an engine controller coupled to a sensor and an engine, and a locomotive controller coupled to the engine controller. The sensor outputs a first alert signal to the engine controller, including the current load and the loading rate of one or more particulate filter units. The engine controller determines a projected load and projected loading rate of the one or more particulate filter units along a route, and a time gap or distance gap based on a trip plan until the one or more particulate filter units are fully loaded. The engine controller determines a time region or distance region to remove particulate matter from the filter unit.

  • Patent number: 7925431
    Abstract: A system is provided for removing particulate matter from a diesel particulate filter. The system includes an engine controller coupled to the diesel engine, and to a locomotive controller. The locomotive controller includes an algorithm to create a trip plan to optimize the performance of the locomotive along a route in accordance with a power setting of the diesel engine at each location along the route. Each sensor is configured to output a first alert signal to the engine controller once the trapped particulate matter exceeds a predetermined threshold. Upon receiving the first alert signal, the engine controller communicates with the locomotive controller to determine a time region or distance region within the trip plan when the power setting exceeds a power threshold. The engine controller increases the temperature of the diesel exhaust gas entering the diesel particulate filter during the time region or distance region.
