Abstract
A dosing lance assembly for an exhaust component includes a housing and a delivery conduit. The housing includes a plate, an endcap, and a pipe. The plate has a first channel. The endcap has a second channel. The pipe has a first end coupled to the plate and a second end coupled to the endcap. The delivery conduit has a first end coupled to the plate and a second end coupled to the endcap, such that reductant is flowable from the first channel to the second channel. When the housing is at an ambient temperature, (i) a length of the delivery conduit is greater than (ii) a first distance between a location at which the first end of the pipe is coupled to the plate and a location at which the second end of the pipe is coupled to the endcap.
