Abstract
A reductant delivery unit () includes a fluid injector () and a flange () coupled with the fluid injector. An exhaust boss () has a surface () defining a through-hole () that communicates with a vehicle's exhaust flow path. The flange is coupled to a mounting surface such that the outlet of the fluid injector communicates with the exhaust flow path so as to control injection of urea solution into the exhaust gas flow path. A gasket () is sandwiched between the flange and the mounting surface. The gasket has a surface () defining a through-hole () therein that communicates with the through-hole in the exhaust boss to permit the urea solution to pass from the fluid outlet to the exhaust flow path. Gasket shielding structure () covers the surface defining the through-hole in the gasket to prevent the urea solution from contacting the gasket.
