Abstract
An ammonia (reductant) injector for delivering a ammonia into an engine exhaust stream is disclosed. Generally speaking, the injector has a body with an inlet fluidly coupled to a plurality of channels within the body, a plurality of discharge ports, each port being fluidly coupled to at least one channel, and an ammonia feed line connected to the inlet of the body. The plurality of discharge ports are preferably spaced one from another such as to optimize the dispersion of ammonia from the ports throughout a cross-sectional portion of an engine exhaust stream.
