    摘要: An exhaust aftertreatment system including an exhaust flow area, a first bank of one or more exhaust treatment devices in fluid communication with the exhaust flow area and a second bank of one or more exhaust treatment devices in fluid communication with the exhaust flow area. The first bank may be arranged in parallel with the second bank and inlet of the first bank is configured to provide greater flow resistance to the exhaust than the inlet of the second bank.

    摘要: An engine exhaust aftertreatment system including a mixer disposed in the exhaust stream. The mixer includes a mesh section having a mesh of wires and may include a baffle section having a deflector that redirects a direction of flow of the exhaust stream. The mesh section may not extend across an entire width of an exhaust conduit containing the exhaust stream. The mesh section may also be sized and located to intersect the reductant introduced by the injector.

    摘要: A fuel injector for a machine is disclosed. The fuel injector has a nozzle member with a first end and a second end. The first end of the fuel injector has at least one orifice. The fuel injector also has a control chamber located at the second end of the nozzle member with an end wall portion approximately orthogonal to an axial direction of the nozzle member. The fuel injector further has a port disposed in the end wall portion of the control chamber and at least one passageway in fluid communication with the control chamber via the port. The fuel injector additionally has a needle valve element with a tip end and a base end. The tip end is configured to selectively block fuel flow through the at least one orifice. The base end has a recess configured to cap off the port.
