Zusammenfassung:A system for reducing emissions in an engine is provided. The system includes a primary fuel tank having a primary fuel. The system also includes a secondary fuel tank having a secondary fuel. The system further includes a separator in fluid communication with the secondary fuel tank or the primary fuel tank or both the secondary fuel tank and the primary fuel tank, the engine and a hydrocarbon-selective catalytic reduction subsystem. The subsystem separator separates a less volatile portion of the secondary fuel or the primary fuel from a more volatile portion, said less volatile portion of the secondary fuel or the primary fuel in the separator is routed to the hydrocarbon-selective catalytic reduction subsystem and said more volatile portion of the secondary fuel or the primary fuel in the separator is routed to the engine.
