Abstract

A lance injector assembly for an exhaust component includes: an exhaust conduit; a shaft configured to extend into the exhaust conduit and dispense reductant from a hydraulically-actuated valve; an actuator configured to operate the hydraulically-actuated valve; and a mounting system configured to couple the actuator and the shaft to the exhaust conduit. The mounting system prevents the actuator from directly contacting the exhaust conduit.
