    • System (10) and method for supplying reductants to an emission treatment system. (28) The system includes a fuel tank (14) adapted to supply a premixed fuel stream that includes a primary component and a reductant component, and an engine (12) in fluid communication with the fuel tank(14) , wherein the engine (14) is configured to create an emission. The engine (14) includes an emission treatment system (28) to treat the emission. The system (10) also includes a separation system (32) that includes a membrane with differential permeability for the reductant component relative to the primary component. The separation system (32) is configured to receive at least a portion of the premixed fuel stream from the tank (14) and to separate the premixed fuel stream into a first fraction (44) and a second fraction (3S) . The first fraction (44) includes a higher concentration of the reductant component than the second fraction, (36) and the separation system (32) is configured to supply the first fraction (44) to the emission treatment system (28) .
    • 系统(10)以及将还原剂供给排放处理系统的方法。 (28)该系统包括适于提供包括主要部件和还原剂部件的预混合燃料流的燃料箱(14)和与燃料箱(14)流体连通的发动机(12),其中发动机 14)被配置为产生发射。 发动机(14)包括用于处理排放物的排放处理系统(28)。 系统(10)还包括分离系统(32),其包括相对于主要组分的用于还原剂组分的具有差异渗透性的膜。 分离系统(32)构造成从罐(14)接收至少一部分预混燃料流,并将预混燃料流分离成第一级分(44)和第二级分(3S)。 第一部分(44)包括比第二部分更高浓度的还原剂组分,(36)和分离系统(32)构造成将第一级分(44)供应到排放处理系统(28)。
