Abstract

A system includes a cylindrical blend chamber having two inlets and one outlet. The outlet is fluidly coupled to a transfer line, and a nozzle is positioned downstream of the transfer line. The nozzle is fluidly coupled to an exhaust stream of an internal combustion engine. The system further includes a first inlet fluidly coupled to a diesel exhaust fluid (DEF) stream, and a second inlet fluidly coupled to an air stream. The DEF stream and the air stream intersect at a divergent angle.
