    摘要： A method for supplying gaseous fuel from a liquid state to an internal combustion engine includes employing a second internal combustion engine as a source of energy, pumping the gaseous fuel in the liquid state by transforming energy from the source of energy into mechanical work for the pumping, exchanging waste heat from the second internal combustion engine in a first heat exchange fluid circulating through the second internal combustion engine to a second heat exchange fluid, vaporizing the gaseous fuel pumped from the liquid state with heat from the second heat exchange fluid, and delivering the gaseous fuel vaporized from the liquid state to the internal combustion engine. Pressure of the gaseous fuel delivered to the internal combustion engine is maintained within a predetermined range of tolerance by the pumping.

    摘要： An improved apparatus supplies gaseous fuel from a liquid state to an internal combustion engine comprising an electrical energy generating apparatus for generating electrical energy from a store of chemical energy. A liquid pumping apparatus for pumping the gaseous fuel in the liquid state includes an energy converter for converting the electrical energy to mechanical energy which drives the liquid pumping apparatus. The liquid pumping apparatus also includes a first heat exchanger for vaporizing the gaseous fuel received from the pumping apparatus and a controller programmed to operate the liquid pumping apparatus to maintain a pressure of the gaseous fuel supplied to the internal combustion engine within a predetermined range.

    摘要： A supply of gaseous fuel on a tender car for fuelling a locomotive engine requires the coordination of a variety of operational modes to improve the safety and efficiency 10 when operating components for delivering, refueling, draining, capturing and storing gaseous fuel. A method and apparatus for managing a supply of gaseous on a tender car comprises receiving on the tender car a command signal from the locomotive commanding delivery of gaseous fuel from the tender car to the locomotive; transferring from the tender car at least one status signal to the locomotive indicating 1 status of the tender car; representing a plurality of operational modes of the tender car as a plurality of states; and transitioning between the plurality of states in response to the command signal and the at least one status signal.
