Abstract

PURPOSE: To prevent the vaporization of the reducing agent inside the injector and to aboid the vapor lock and clogging of the reducing agent, by equipping the cover plate parts in close vicinity to the injector for injecting the aqueous solution of urea, NH3 or hydrazine to be used as the reducing agent into the exhaust gas containing NOx.
