摘要： An interchangeable additive injection apparatus provides a plurality of flow paths from one or more upstream additive tanks to one or more downstream fuel containers. A plurality of additive lines converge into an additive conduit at a manifold disposed within the apparatus. A plurality of valves associated with the additive lines are selectively opened and closed to isolate one of the flow paths. A metering device is disposed along the additive conduit for measuring the flow of additive therethrough. A reversible, multiple port housing surrounds at least the valves and manifold. In a forward orientation, a plurality of upstream ports are coupled to upstream additive tanks, and a downstream port is coupled to a fuel tank. By reversing the housing, the apparatus is placed in a reverse orientation wherein the upstream port is connected to an upstream additive tank and a plurality of downstream ports are connected to downstream fuel tanks. In either orientation, an expansion apparatus may be coupled to an expansion port on the additive injection apparatus to provide a number of additional ports and flow paths. A controller is coupled with the injection apparatus to monitor and control the associated pumps, valves and meters.
摘要翻译：可互换的添加剂注射装置提供从一个或多个上游添加剂罐到一个或多个下游燃料容器的多个流动路径。多个添加剂线在设置在设备内的歧管处汇合成添加剂导管。与添加剂线相关联的多个阀选择性地打开和关闭以隔离流路之一。计量装置沿着添加剂导管设置，用于测量添加剂的流动。可逆的多端口外壳至少围绕阀和歧管。在向前方向上，多个上游端口联接到上游添加剂罐，并且下游端口联接到燃料箱。通过反转壳体，装置处于相反的方向，其中上游端口连接到上游添加剂罐，并且多个下游端口连接到下游燃料箱。在任一方向上，膨胀装置可以联接到添加剂注入装置上的膨胀端口以提供多个附加的端口和流动路径。控制器与注射装置结合以监测和控制相关联的泵，阀和仪表。
