    摘要： A control system for a fuel injector is disclosed. The control system has a nozzle member with at least one orifice, and a needle check valve. The needle check valve is recipratingly disposed to open and close the at least one orifice. The control system also has a control chamber located at the base end of the needle check valve, and a control valve movable to selectively drain and fill the control chamber. The control system further has an injector body, a first piston located within the injector body, and a second piston located within the injector body. The first piston is operatively connected to the control valve to move the control valve. The second piston is located a distance from the first piston to form a coupling chamber. The control system additionally has a partial-ball check valve associated with the coupling chamber to selectively replenish the coupling chamber.

    摘要： A turbocharger (32) creates intake manifold boost for a diesel engine (10). At times, exhaust valve opening is increasingly retarded in relation to the engine operating cycle to cause the turbocharger to increase boost, engine fueling is also increased in relation to the increased boost, and in response to any incipient surging of the compressor resulting from such increasingly retarded exhaust valve opening and such increased engine fueling, compressed charge air is bled from the intake manifold to counter the incipient surging and thereby avoid any significant turbocharger surge.

    摘要： A reductant dosing system for an engine is disclosed. The reductant dosing system may have a supply of reductant, a reservoir configured to hold pressurized reductant, and a pump configured to draw reductant from the supply and discharge reductant at an elevated pressure into the reservoir. The reductant dosing system may also have a plurality of injectors fluidly connected to the reservoir, and a drain valve fluidly connected between the reservoir and the supply.

    摘要： An engine exhaust aftertreatment system including a bend routing an exhaust flow in a curved direction to a straight part. A nozzle is mounted in the bend to introduce a spray of a fluid with a axis of symmetry into the exhaust flow. The axis of symmetry intersects the exhaust flow traveling in the curved direction at a intersection angle of less than 50 degrees.
