Temperature-based control of reagent distribution

The present disclosure provides a method of treating a diesel exhaust system that includes heating a reagent to a temperature such that at least a portion of the reagent is heated to a gaseous phase, injecting the reagent into a diesel exhaust stream upstream of a catalyst, and reacting the diesel e...

description	The present disclosure provides a method of treating a diesel exhaust system that includes heating a reagent to a temperature such that at least a portion of the reagent is heated to a gaseous phase, injecting the reagent into a diesel exhaust stream upstream of a catalyst, and reacting the diesel exhaust with the heated reagent over the catalyst to convert NOx into N2 and H2O. The heating modulates a mass flow rate of the reagent by converting a state of matter of the reagent at least partially to the gaseous phase prior to or after being injected, and the heated reagent in the gaseous form reduces deposit formations within the diesel exhaust system.
