  • Publication number: 20180313303
    Abstract: Various methods for controlling EGR rate are disclosed. In one embodiment, a method comprises routing at least a portion of exhaust from a first exhaust manifold to an intake manifold, and not to atmosphere, the first exhaust manifold exclusively coupled to a first cylinder group. The method further includes routing exhaust from at least one additional exhaust manifold coupled to a corresponding at least one additional cylinder group to atmosphere, and during a first engine operating condition where an engine fuel demand is below a threshold demand, not injecting fuel to each of a subset of cylinders in the first cylinder group while injecting fuel to a subset of all cylinders coupled to the at least one additional exhaust manifold, where a number of cylinders of the subset of cylinders in the first cylinder group decreases in response to an increase in a target EGR rate.

  • Patent number: 9422879
    Abstract: Various systems and method for controlling exhaust gas recirculation (EGR) in an internal combustion engine are provided. In one embodiment, a method includes injecting fuel to a subset of cylinders that includes less than all cylinders of a first cylinder group to obtain a target EGR rate. The first cylinder group provides exhaust gas through an exhaust gas recirculation (EGR) passage structure fluidly coupled between the first cylinder group and an intake passage structure. The method further includes injecting fuel to at least one cylinder of a second cylinder group. The second cylinder group provides substantially no exhaust gas through the EGR passage structure.

  • Publication number: 20160076504
    Abstract: Various methods and systems are provided for a pressure relief valve of a fuel system. In one example, a valve includes a first chamber in fluid communication with a first fuel line, a second chamber in fluid communication with a second fuel line and in fluid communication with a fuel storage tank, a piston separating the first chamber from the second chamber, and a needle coupled to the piston and controlling a flow passage between the second fuel line and the second chamber, where the piston and needle are sized such that a force applied on the piston by the first chamber parallel to an axis of movement of the piston maintains the needle in a closed position when the first fuel line flows fuel at a first pressure and the second fuel line flows fuel at a second pressure, the second pressure greater than the first pressure.

  • 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: 8431028
    Abstract: A system for automated water drainage in a fuel system includes a fuel-water separator, a water sensor, first and second drain valves, a drain pressure sensor, and a control system, which is operably connected to the first and second drain valves, the water sensor, and the drain pressure sensor. The water sensor is disposed in the fuel-water separator for detecting the presence of water. The first drain valve is in fluid communication with the fuel-water separator, and the second drain valve is in fluid communication with the first drain valve; a fluid duct connects the first and second drain valves. The drain pressure sensor is positioned in the fluid duct, for detecting pressure levels in the fluid duct. The control system automatically operates the first and second drain valves, for removing purge liquid from the fuel-water separator, based on signal outputs of the water sensor and the drain pressure sensor.
