Zusammenfassung:	A system and method for delivering a reductant into an engine exhaust stream for use in the reduction of NOx is disclosed. The system includes a cartridge having an interior space for storing the reductant containing material, a fluid supply line fluidly connected to the cartridge for receiving the reductant, a pressure boosting device for boosting the flow of reductant, a flow management device, and, an injector for injecting the reductant into an after-treatment system for combining with the exhaust stream. The reductant may include ammonia. Use of the pressure boosting device increases the reductant pressure into the aftertreatment system, providing for a reduction in the time to inject the reductant into the exhaust stream, while improving the distribution of reductant into the exhaust stream.
