摘要： 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.

摘要： A lance injector assembly for an exhaust component includes: a shaft configured to extend into an exhaust conduit of the exhaust component, the shaft being hollow so as to define a channel therethrough, wherein an opening is defined in a wall of the shaft proximate to a second end of the shaft that is opposite the first end; a cap coupled to a first end of the shaft; and a supply line disposed within the channel defined by the shaft, wherein a nozzle is disposed at a downstream end of the supply line, the nozzle being fluidly coupled to the shaft around the opening such that reductant is able to flow from the nozzle through the opening and into an exhaust gas flowing through the exhaust conduit. Air is present in the space between the supply line and the wall of the shaft, the air inhibiting heat transfer to the supply line.

摘要： A selective catalytic reduction system may include a single housing defining a single centerline axis. The selective catalytic reduction system may also include a diesel particulate filter disposed within the single housing and having a DPF center axis aligned with the single centerline axis. The selective catalytic reduction system may also include an SCR catalyst disposed within the single housing and having a center axis aligned with the single centerline axis. In some implementations, the diesel particulate filter may include one or more SiC filters. In some implementations, the SCR catalyst may include one or more extruded SCR catalysts.

摘要： Methods of combining catalytic plates into an assembly of a non-monolithic structure, such as a catalyst substrate or filter assembly, of an exhaust aftertreatment system. A plurality of plates may be disposed within a housing in an arrangement that may define a catalytically active volume of a substrate. Each of the plurality of plates may be single-curved or multiple-curved and/or may be represented by three-dimensional nestable structures. The arrangement of plates may be configured such that the flow is axial, radial, or represented by a hybrid, multi-segment intake path. The plurality of plates may be arranged such that they are configured to receive targeted amounts of coating agent, which may differ among the plates.

摘要： An aftertreatment system includes a filter configured to receive an exhaust gas and a selective catalytic reduction (SCR) system configured to treat the exhaust gas. A body mixer is disposed downstream of the filter and upstream of the SCR system. The body mixer includes a housing defining an internal volume and including at least a first passageway, a second passageway, and a third passageway. The first passageway receives a flow of the exhaust gas from the filter and directs the flow of the exhaust gas towards the second passageway. The second passageway redirects the flow in a second direction opposite the first direction towards the third passageway. The third passageway redirects the flow in a third direction opposite the second direction towards the SCR system. An injection port is disposed on a sidewall of the housing and configured to communicate an exhaust reductant into the internal volume.

摘要： A method for reducing reductant deposits in an exhaust conduit fluidly coupled to an engine comprises operating the engine to produce an exhaust gas. The exhaust gas is communicated into the exhaust conduit which has an initial cross-sectional area. An initial flow rate corresponding to an initial flow velocity of the exhaust gas entering the exhaust conduit is determined. The initial flow rate and, thereby the initial flow velocity of the exhaust gas, increases or decreases based on an operating condition of the engine. The initial flow rate of the exhaust gas is compared with a predetermined threshold. If the initial flow rate of the exhaust gas is lower than the predetermined threshold, a cross-sectional area of the exhaust conduit is reduced. The reducing of the cross-sectional area causes the exhaust gas to have an adjusted flow velocity greater than the initial flow velocity.
