Abstract:

A multi-stage mixer includes a multi-stage mixer inlet, a multi-stage mixer outlet, a first flow device, and a second flow device. The multi-stage mixer inlet is configured to receive exhaust gas. The multi-stage mixer outlet is configured to provide the exhaust gas to a catalyst. The first flow device is configured to receive the exhaust gas from the multi-stage mixer inlet and to receive reductant such that the reductant is partially mixed with the exhaust gas within the first flow device. The first flow device includes a plurality of main vanes and a plurality of main vane apertures. The plurality of main vane apertures is interspaced between the plurality of main vanes. The plurality of main vane apertures is configured to receive the exhaust gas and to cooperate with the plurality of main vanes to provide the exhaust gas from the first flow device with a swirl flow.

B01J 29/76
B01J 37/06
B01D 53/94

Abstract:

A method for increasing a catalytic efficiency of a catalyst, comprising providing a catalyst. Finally, the catalyst is installed into a selective catalytic reduction system of an aftertreatment system configured to reduce constituents of an exhaust gas generated by an engine. The catalyst is soaked in a liquid which consists essentially of one of water or a water-comprising solution. The soaking occurs at least one of before or after installing the catalyst in the selective catalytic reduction system. The catalyst can include a copper zeolite catalyst.

Assignee:

Cummins Emission Solutions Inc. - Columbus IN

International Classification:

F01N 3/20

Abstract:

A liquid reductant injector nozzle includes a first portion defining a hollow cylindrical static chamber, in fluid communication with second portion defining a hollow frustoconical converging section, which is in turn in fluid communication with a sharp edged type discharge orifice. The hollow cylindrical static chamber is in reductant receiving communication with a reductant source, and has a first and second circular opening having equal diameters. The second circular opening is downstream of the first circular opening. The hollow frustoconical converging section is in reductant receiving communication with the hollow cylindrical static chamber via the second circular opening. Reductant received from the reductant source is discharged through the discharge orifice. A sidewall of the hollow cylindrical static chamber and a frustum side of the frustoconical converging section define an angle of convergence of the liquid reductant injector nozzle relative to a plane of the second circular opening.

Abstract:

Apparatuses and methods for urea dosing of an exhaust after treatment system are disclosed. Exemplary apparatuses include a chamber configured to receive pressurized gas at a first inlet, receive urea solution at a second inlet and provide a combined flow of pressurized gas and urea to an outlet, flow passage extending from the first inlet to a seating surface, and a valve member configured to move between an open position in which the valve member is spaced apart from the seating surface and a closed position in which the valve member contacts the seating surface. As the valve member moves from the open position to the closed position, the valve member contacts the seating surface at a first location and wipes an area of the seating surface extending from the first location in a direction toward the flow passage.
