An injector mount clamp for coupling an injector of an exhaust gas treatment system to an exhaust conduit of an engine while the conduit is in an installed position includes a resilient monolithic clamp body having an aperture extending therethrough and being shaped as a split collar having a first end spaced apart from a second end a distance allowing the clamp body to be transversely moved relative to an exhaust flow direction to a position circumferentially surrounding the exhaust conduit. An injector mounting boss is disposed on the clamp body and defines a passage that fluidly communicates with the aperture of the clamp body. The mounting boss has a mounting face configured to oppose the injector.

Retrofit injector mount

The present invention provides methods and apparatus for injecting fluid, such as an aqueous urea solution, into an exhaust stream in order to reduce oxides of nitrogen (NOx) emissions from diesel engine exhaust. More particularly, the present invention provides a dual-injector system for diesel emissions control and corresponding methods.
