    摘要: A reformer system may include a reformer device having a fuel inlet, an air inlet and a gas outlet, a first valve set coupled to the fuel inlet and configured to selectively supply a reformer fuel flow from an engine fuel flow to the fuel inlet, a second valve set coupled to the air inlet and configured to selectively supply a reformer air flow from a compressor outlet air flow to the air inlet, and a controller in electrical communication with the first valve set and the second valve set. The controller may determine a target reformer fuel flow based on a target gas flow, determine a target reformer air flow based on the reformer fuel flow and a target air-to-fuel ratio, adjust the reformer fuel flow according to the target reformer fuel flow, and adjust the reformer air flow according to the target reformer air flow.

    摘要: A vehicle includes a vehicle platform and a natural gas fueled engine attached to the vehicle platform. The engine provides tractive power to at least one drive wheel. The vehicle includes an enclosure, attachable to the vehicle platform, to contain an array of natural gas storage vessels. The array of natural gas storage vessels is disposed completely within the enclosure. Each storage vessel of the array of natural gas storage vessels is in fluid communication with a single outlet port for selectively extracting the natural gas from the array of natural gas storage vessels. Each storage vessel of the array of natural gas storage vessels is in fluid communication with a single natural gas fill port.
