Abstract
Methods and apparatus for injecting reagent, such as an aqueous urea solution, into an exhaust stream in order to reduce emissions from an engine exhaust. The present teachings can use a whirl plate having a plurality of whirl slots surrounding an exit orifice of an injector, which produce a high velocity rotating flow in the whirl chamber. When the rotating flow of reagent is passed through the exit orifice into an exhaust stream, atomization occurs from a combination of centrifugal force and shearing of the reagent by air as it jets into the exhaust stream.
