    摘要： The invention provides a NOx adsorber aftertreatment system for internal combustion engines which utilizes a plasma fuel converter operatively coupled to at least one NOx adsorber to aid in the regeneration of the NOx adsorber. Fuel and engine exhaust is injected into a plasma fuel converter upstream of a NOx absorber producing reductant such as H2, and CO, which are inlet into the NOx absorber. Reductants such as H2 and CO acting along and together help to efficiently regenerate the NOx Adsorber which in turn releases exhausts products such as CO2 and N2. Using the reductants generated by the plasma fuel converter NOx adsorbers, catalytic soot filter, and the like can be regenerated at exhaust temperatures less than 250° C. The plasma fuel converter, NOx adsorber regenerating aftertreatment system of the present invention may be used with any suitable control system.

    摘要： A control valve comprising a valve housing including a valve cavity, an inlet means formed in the valve housing for directing fluid into the valve cavity, and an outlet means formed in the valve housing for directing fluid out of the valve cavity. The control valve further includes a valve element mounted for reciprocal movement in the valve cavity between open and closed positions and biased toward the closed position by fluid pressure forces. A valve seat is associated with the valve element which engages the valve seat when in the closed position and permits flow between the valve seat and the valve element when in the open position. A flow force inducing means is positioned adjacent the valve element for redirecting fluid from the inlet means through a predetermined flow path arranged relative to the valve element to cause fluid flow to impact the valve element and create flow induced forces of sufficient magnitude necessary to advantageously counteract the fluid pressure forces.

    摘要： A swirl tip injector nozzle housing is provided for a fuel injector which includes a fuel atomization enhancing feature for creating effective fuel atomization and breakup during discharge from the injector. The fuel atomization enhancing feature includes a plurality of curvilinear spray holes having an angle of curvature equal to approximately 90 degrees. Fuel flowing from the inlet of each spray hole to the outlet is induced, by the 90 degree angle of curvature, to flow through a tangential flow path or swirl within the spray hole causing rapid spreading and breakup of the fuel jet spray upon exiting the outlet of the spray hole. The fuel atomization enhancing feature may also include positioning each spray hole so as to extend orthogonally from the interior surface of the fuel cavity to create optimal entry of the fuel into the tangential flow path.
