Abstract
Various diffusion apparatuses are provided for facilitating the injection of a nitrogen-oxides reductant solution, such as urea, into exhaust gas as part of a selective catalytic reduction system. These diffusion apparatuses direct exhaust gas from an exhaust pipe, through a conduit, and into a diffusion chamber where urea is injected. The flow of exhaust gas through the conduit provides improved transport of injected reductant solution into the exhaust pipe, and adhesion of the reductant solution to the walls of the diffusion chamber is reduced.
