Abstract
A system for applying secondary fluids to vehicular exhaust after-treatment apparatus utilizes a mixing chamber coupled for receipt of a portion of the vehicle's exhaust flow. A source of secondary fluid is coupled to the mixing chamber and a fluid distribution element is positioned in a mean exhaust flow conduit upstream of the exhaust after-treatment apparatus. The fluid distribution element presents a preselected pattern of fluid flow toward an upstream face of the after-treatment apparatus.
