Abstract
A selective catalytic reduction system for engine exhaust injects a solution comprising a source of ammonia, preferably an aqueous urea solution, or other ammonia solution, to preferably evaporate, decompose and hydrolyze to produce ammonia to react with and reduce NOx in the exhaust. An inertial impactor in the housing between the injector and the catalyst is impacted by the solution droplets and holds same until evaporated, decomposed and hydrolyzed to ammonia.
