Patent number: 10619544Abstract: A dosing module includes: a frame assembly comprising a plurality of panels; a first manifold configured to separately receive reductant and air and including: a first connector, and a second connector; and a dosing tray including: a base panel, a second manifold configured to separately receive the air and the reductant and provide the air and the reductant back to the first manifold, a third connector selectively coupled to the first connector, and a fourth connector selectively coupled to the second connector. When the third connector is coupled to the first connector and the fourth connector is coupled to the second connector, the reductant or air is routed to the first connector, from the first connector to the third connector, from the third connector to the fourth connector, from the fourth connector to the second connector, and from the second connector outside of the dosing module.Type: GrantFiled: March 27, 2018Date of Patent: April 14, 2020Assignee: Cummins Emission Solutions Inc.Inventors: Tyler Kent Lorenz, Taren DeHart, Matthew K.
