Abstract:
1. A system for reducing emissions in an engine, the system comprising: a primary fuel tank having one of diesel or gasoline; a secondary fuel tank having liquefied natural gas (LNG); and a separator in fluid communication with the secondary fuel tank, the engine, and a hydrocarbon-selective catalytic reduction subsystem via a reductant injector, wherein the primary fuel tank is in fluid communication with the engine and the reductant injector such that a more volatile portion of the diesel or a more volatile portion of the gasoline is routed to the reductant injector; wherein the separator separates a less volatile portion of the LNG from a more volatile portion of the LNG, said less volatile portion of the LNG in the separator is routed to the hydrocarbon-selective catalytic reduction subsystem and said more volatile portion of the LNG in the separator is routed to the engine.
