Abstract
An exhaust component assembly for a vehicle exhaust system includes a housing defining an internal cavity configured to receive an exhaust gas after-treatment component. A first chamber is in fluid communication with the internal cavity upstream of the exhaust gas after-treatment component. A first nozzle introduces fluid into the first chamber and a first valve controls flow of the fluid from the first chamber into the internal cavity. A heat source is associated with the first nozzle or first chamber. A second chamber is in fluid communication with the internal cavity upstream of the exhaust gas after-treatment component, and the second chamber is a non-heated chamber. A second nozzle introduces fluid into the second chamber and a second valve controls flow of the fluid from the second chamber into the internal cavity. A controller controls the first and second valves based on at least one predetermined operating condition.
