Abstract
An exhaust after-treatment system for mitigating deposition of urea utilizing selective catalytic reduction (SCR) in exhaust receiving communication with an exhaust gas stream produced by an engine system, including an exhaust passage including a mixing duct through which the exhaust gas stream flows. A fluid reservoir contains a urea solution and a fluid pump is fluidly connected to the fluid reservoir to draw the urea solution from within the fluid reservoir. A fluid injector is configured to receive the urea solution from the fluid pump and deliver the urea solution into the mixing duct and at least one vibration mechanism is mechanically coupled to one or both of the fluid injector and the mixing duct to generate and convey vibrations thereto to mitigate the deposition of urea.
