Provided is a catalyst article for simultaneously remediating the nitrogen oxides (NOx), particulate matter, and gaseous hydrocarbons present in diesel engine exhaust streams. The catalyst article has a soot filter coated with a material effective in the Selective Catalytic Reduction (SCR) of NOx by a reductant, e.g., ammonia.

A mounting assembly far mounting a diesel oxidation catalyst (DOC) system within a work vehicle may generally include a support bracket having a first side and a second side. The mounting assembly may also include a mount plate configured to be coupled to the first side of the bracket. The mount plate may include first and second plate walls and may define an elongated slot through the first plate wall. Additionally, the assembly may include a retention band configured to at least partially wrap around a housing of the DOC system between a first end configured to be coupled to the mount plate and a second end configured to be coupled to the second side of the support bracket. The mount plate may be configured to be moved laterally relative to the support bracket to allow the retention hand to be tightened and loosened around the housing.

A method of manufacturing an exhaust gas carrying device, in particular an exhaust gas purification device, and a tool provided therefor include segment-like jaws that are used to deforma an outer housing. The jaws have indentations or projections adjacent to each other, and which are complementary to form a continuously surrounding indentation/projection. The reshaped outer housing is provided with one or more surrounding projections or indentations by the deformation.

An emissions cleaning module is provided including a first support, a second support and a mixer module. The mixer module extends between the first support and the second support. The mixer module includes an outer body and an inner body located within the outer body. In addition the outer body is fixedly retained to the first support and the second support. Further, a first end of the inner body is slidingly retained within the outer body, and a second end of the inner body is fixedly retained relative to the outer body at or near the second support.

A reactor cell for measuring gas and liquid permeation is disclosed. The reactor cell comprises a reactor module having a reactor chamber and a cover. A first hole extends into the reactor chamber from a first surface, a second hole opposing the first hole extends into the reactor chamber from a second surface, a third hole extends into the reactor chamber from a third surface and a fourth hole opposing the third hole extends into the reactor chamber from a fourth surface. A hollow fiber is supported by and sealed into the first and second holes of the reactor module. The first and second ends of the hollow fiber are sealed with a sealing solution. Methods for making and using the reactor cell are also disclosed. As made and used, the reactor cell further comprises a molecular sieving membrane grown on an inner bore surface of the hollow fiber.

A mounting assembly for mounting a diesel oxidation catalyst (DOC) system within a work vehicle may generally include a support. bracket having a first side and a second side. The mounting assembly may also include a mount plate configured to be coupled to the first side of the bracket. The mount plate may include first and second plate walls and may define an elongated slot through the first plate wall. Additionally, the assembly may include a retention hand configured to at least partially wrap around a housing of the DOC system between a first end configured to he coupled to the mount plate and a second end configured to be coupled to the second side of the support bracket. The mount plate may be configured to he moved laterally relative to the support bracket to allow the retention band to he tightened and loosened around the housing.

Reactor installation tools and methods for installing reactor components in a reactor tube are described herein. A reactor installation tool can include a releasable attachment assembly for securing the tool to a reactor or support for holding reactor components. The tool can include a movable cylinder that can be actuated to engage and push on a reactor component in an interior region of the reactor for positioning the contents of the reactor in a desired location. The tool can further include means for supply blasts of compressed gas to an interior region of the reactor to aid in the expansion and positioning of the reactor contents. A skirt seal can be used to ensure that the blasts of compressed gas are contained in the interior region of the reactor.

An exhaust mixer provided may be used for mixing an additive, such as urea, in exhaust fluid flow. The exhaust mixer may be useful in reducing or preventing build-up of solid additive deposits by increasing efficiency of mixing of the additive. The exhaust mixer may be located at least partially within a mixing conduit and includes plurality of elongate mixing blades held in spaced configuration by a support. Each mixing blade may have a longitudinal axis extending along a longitudinal axis of the mixing conduit, wherein an injector module may be located upstream of the inlet of the mixing conduit.

A catalytic converter substrate comprising a plurality of micro-structured hollow ceramic tubes, each tube having an inside surface and an outside surface, the inside surface having openings to micro-channels distributed radially throughout the tube cross-section, the micro-channels extending from the openings in the inside surface towards the outside surface.

An ammonia generating device for treating exhaust gases of internal combustion engines, notably of automobile vehicles, includes a reservoir having a body capable of releasing ammonia by desorption and a heating device positioned inside the reservoir to heat the body in the reservoir. The heating device comprises a heat generating element that has an elongated form. The heating device further includes at least one heat transfer feature laid out along an axial direction of the heat generating element and extending in a direction radial to the heat generating element.
