An injector configured to introduce a reductant into an exhaust stream, the injector comprising:
- a body including a conduit with a first diameter;
- a nozzle fluidly coupled to the conduit and disposed at a distal end of the body;
- and
- an extension extending from the distal end of the body, the extension extending from the distal end of the body by at least a distance equal to the first diameter.
An aftertreatment module for treating constituents of exhaust gases of an internal combustion engine, the aftertreatment module comprising:
- a housing;
- an injector disposed within the housing, the injector including:
- a body coupled to the housing and including a conduit with a first diameter;
- a nozzle fluidly coupled to the conduit of the body and disposed at a distal end of the body;
- and
- an extension extending from the distal end of the body, the extension extending from the distal end of the body by at least a distance equal to the first diameter;
- and
- a mixing duct disposed downstream of the injector and within the housing.
An injector configured to introduce a reductant into an exhaust stream, the injector comprising:
- a body;
- a nozzle fluidly coupled to, and disposed at a distal end of, the body;
- and
- an extension extending from the distal end of the body, the extension configured to equalize a velocity of exhaust flow over the nozzles in at least two directions.
