  • Publication number: 20120241258
    Abstract: A lubricant supply system for a gearbox includes a lubricant flow circuit having, in fluid flow sequence: a variable-flow rate first pump; an lubricant cooler; and a gearbox. The system also includes: a first temperature sensor for sensing a temperature of lubricant circulating within the lubricant flow circuit; a pressure sensor for sensing a pressure of lubricant circulating within the lubricant flow circuit; and a controller operably connected to the pressure and temperature sensors and to the first pump. The controller is operable to control flow of the pump in response to the sensed temperature and to the sensed pressure.

  • Patent number: 7072747
    Abstract: A method of controlling operation of a train (T) for passage of the train through a tunnel. The train has a plurality of locomotives (L1-Ln) pulling the train. The position of the lead locomotive relative to the tunnel entrance is determined, as is the amount of time before the train enters the tunnel. Each locomotive is separately configured for passage through the tunnel as a function of performance characteristics of the locomotive and the locomotive's current operating status, as the train approaches the tunnel. Once the train enters the tunnel, the performance characteristics of each locomotive are continually monitored. The performance requirements for one or more of the locomotives are then dynamically changed as a function of conditions within the tunnel and the current performance characteristics of each locomotive. This is done to maintain a sufficient combined performance capability from the locomotives to move the train through the tunnel.

  • Patent number: 6604515
    Abstract: A cooling apparatus (10) and method for a turbocharged internal combustion engine (12). The combustion air (16) exiting a turbocharger (18) is passed over an air-to-water intercooler (40) then over an air-to-air intercooler (42) for heat exchange with liquid coolant and with ambient air (32) respectively. During periods of low ambient air temperature, the combustion air may be directed through a bypass duct (80) around the air-to-air intercooler, and further, may be heated by the coolant in the air-to-water intercooler. A multi-speed fan (44) and/or shutters (48) may be used to control the flow of ambient air across the air-to-air intercooler. A cooling duct (68) provides a flow of ambient air to the fan motor (46) during periods of operation when the flow of ambient air over the air-to-air heat exchanger is restricted by the shutters. Coolant exiting a subcooler (28) has the lowest temperature in the system and is directed to a lube oil cooler (34) for engine lubricant cooling.
