Patent number: 8839517Abstract: A catalytic device and method for forming a catalytic device are described. The devices and methods described can be used for emissions systems in heavy duty diesel engines. In particular, a method of spin forming a catalytic device generally includes disposing a mat about an outer surface of a catalyst substrate and inserting the catalyst substrate and mat inside a shell. The mat is between the shell and the catalyst substrate. The shell, catalyst substrate, and mat can be spin formed into at least a generally elliptical shape but generally other than a circle shape.Type: GrantFiled: April 29, 2013Date of Patent: September 23, 2014Assignee: Cummings Filtration IP, Inc.Inventors: Bryan E.

Patent number: 8691724Abstract: An inlet face for an aftertreatment device that prevents and/or eliminates face-plugging for a passageway where the inlet face is disposed. The inlet face includes a particular end surface disposed on an outer surface at the end of a substrate. The end surface includes at least one of a three-dimensional topographical configuration disposed at the end of the substrate, a chemical coating applied on the end of the substrate, or both a three-dimensional topographical configuration disposed on the end of the substrate and a chemical coating applied on the three-dimensional topographical configuration. As one example, the inlet face can be helpful in preventing carbonaceous fouling, which can result from engine exhaust material, such as carbon soot and other engine exhaust by-products.Type: GrantFiled: September 4, 2012Date of Patent: April 8, 2014Assignee: Cummins Filtration IP, Inc.Inventors: Conrad J.

Patent number: 8114364Abstract: A means for increasing the robustness of a SCR after-treatment system is provided. Specifically, a hydrolysis catalyst coating is applied to multiple surfaces within a decomposition reactor to aid in urea and urea based deposit decomposition and mitigation of urea based deposits. The reactor includes an injector mount attached to a middle tube portion, an inlet tube, an outlet tube and a mixer. A hydrolysis catalyst coating is applied to an inner surface of the injector mount, an inner surface of the middle tube portion, an inner surface of the outlet tube and an outer edge of the mixer. The hydrolysis catalyst coating is capable of decomposing urea and urea based deposits that comes in contact with the hydrolysis catalyst coating and mitigates the formation of urea based deposits.Type: GrantFiled: February 2, 2009Date of Patent: February 14, 2012Assignee: Cummins Filtration IP, Inc.Inventors: Arvind V.
