摘要： One form of the present application is an apparatus including an internal combustion engine structured to produce an exhaust flow, an exhaust system structured to receive the exhaust flow, and a reductant injector structured to inject reductant into a primary passage of the exhaust system upstream of a catalyst. The apparatus further includes an injector passage structured to receive a portion of exhaust upstream of the injector and further structured to flow the exhaust into the primary passage around the injector in a manner such that deposit formation is reduced.

摘要： An exemplary exhaust test tog apparatus includes a housing defining an exhaust flow path extending from an inlet to an outlet. At least a portion of the housing is selectably rotatable relative to an exhaust aftertreatment system. An arm extends from the housing into the exhaust flow path. An exhaust probe configured to measure an exhaust constituent is coupled with the arm and positioned at a location in the exhaust flow path. An actuator is configured to extend and retract the arm to vary the location of the exhaust probe in the exhaust flow path. The exhaust probe is moveable to a plurality of locations within the exhaust flow path through a combination of rotation of the housing and extension and retraction of the arm.

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： Exhaust aftertreatment assemblies and methods of manufacturing and operating exhaust aftertreatment assemblies. The exhaust aftertreatment assembly includes a reductant delivery device, a reductant source fluidly coupled to the reductant delivery device, a mixing chamber positioned between the reductant delivery device and the reductant source and thereby fluidly coupling the reductant source to the reductant delivery device, and a compressed air source fluidly coupled to the mixing chamber upstream of the mixing chamber with respect to the reductant delivery device. The compressed air source provides compressed air to mix with reductant in the mixing chamber.

摘要： An exhaust assisted pipe assembly including an outer portion having an opening for receiving dosed reductant from a dosing module and an inner portion disposed within the outer portion. The inner portion defines a main flow path for receiving a first portion of a fluid from an upstream source, and the inner portion and the outer portion cooperatively define a first flow path and a second flow path. The first flow path is configured to direct a second portion of the fluid from the upstream source past the opening for receiving dosed reductant and into the main flow path to increase momentum of the dosed reductant into the main flow path. The second flow path is configured to direct a third portion of the fluid from the upstream source toward the dosed reductant to decrease the momentum of the dosed reductant in the main flow path.

摘要： Systems and devices for delivering a fluid to an exhaust system. An inlet is configured for receiving the fluid, and a conduit includes openings for expelling the fluid into the exhaust system. A compact gaseous delivery system may include a first conduit in fluid communication with a fluid source, a second conduit in fluid communication with the first conduit, and a plurality of additional conduits in fluid communication with the second conduit and including a plurality of openings for expelling the fluid into the exhaust system. The first conduit, second conduit, and plurality of additional conduits may have axes that are substantially coplanar to form the compact gaseous delivery system that may be disposed within the exhaust system. Implementations may include openings with varying diameters. Other implementations may include a volute conduit with openings.
