摘要： An exhaust aftertreatment module is provided. The exhaust aftertreatment module includes a housing having a first end and a second end. The at least one inlet is disposed between the first end and the second end and is configured to introduce an exhaust into the housing. A mixing tube is disposed downstream of the at least one inlet. The mixing tube is configured to direct the exhaust towards the second end of the housing. The exhaust aftertreatment module further includes a single bank of Selective Catalytic Reduction (SCR) catalysts disposed at an oblique angle to a longitudinal axis of the mixing tube. The single bank of SCR catalysts is configured to receive the exhaust redirected from the second end of the housing.

摘要： A catalytic converter apparatus for use in an exhaust system of an internal combustion engine includes a housing having a gas inlet and a gas outlet, and at least one catalytic substrate element disposed in the housing. The at least one substrate element is divided into a plurality of zones or sections, the zones at least partially separated from one another to inhibit heat flow. The zones can be at least partially separated with walls. The walls can include insulating material for reducing the mobility of heat radially outwardly. Each of the zones defines a generally separate flow passage connecting the inlet and outlet in fluid communication. The apparatus can heat more rapidly from a cold start compared with conventional catalytic converters.

摘要： An exhaust-gas purifying apparatus includes an outer cylinder, a plurality of cylinder-shaped supports, and a catalytic layer. The cylinder-shaped supports are disposed in the outer cylinder, and have an outer peripheral surface and an inner peripheral surface. At least two of the neighboring cylinder-shaped supports contact with each other with the outer peripheral surfaces. The catalytic layer is loaded on at least one of the outer peripheral surface and inner peripheral surface of the cylinder-shaped supports. At least one of the cylinder-shaped supports has a ring-shaped cross-section with a cut-off, and is disposed in the outer cylinder in such an elastically deformed state that it expands in the centrifugal direction. Thus, the exhaust-gas purifying apparatus not only shows a high exhaust-gas purifying ability, but also is good in terms of the assemblage easiness. Moreover, the exhaust-gas purifying apparatus exhibits improved misfire resistance.

摘要： A catalyzer, in particular for internal combustion engines, has a different that widens in the direction of flow upstream of a honeycombed catalyst body (23), a converger (25) that narrows in the direction of flow downstream of the catalyst body (23) and at least one flow guiding body locating within the diffusor and/or converger. In order to achieve a uniform inflow at the front side of the catalyst body (23) without excessively throttling the flow exhaust gases, a flow guiding body (24) composed of a plurality of adjacent and/or imbricated channels having at least partially an increasing cross-section in the direction of flow is arranged at least in the diffusor. The individual channels preferably have an opening angle that prevents burbling at the walls of the individual channels. In addition, the flow guiding body can be coated with a catalytically active material, thus allowing the volume of the diffusor, if necessary of the converger as well, to be also used for housing catalytically active surfaces. This can improve in particular, besides the inflow at the main catalyst body (23), the cold start properties of the catalyzer.

摘要： A catalyst carrier having a circular cell honeycomb structure formed from a plurality of cell passages whose inner surfaces are substantially circular and are coated with a catalyst for oxidizing and/or deoxidizing exhaust gas of a vehicle, wherein the circular-cross-section cells are integrally formed with the catalyst carrier by extrusion. The catalyst carrier allows the catalyst layer to be uniformly coated on the inner surface of the cell while reducing the amount of catalyst consisting of precious metals, and the cell-density can be increased by minimizing the height between the centers of the cells vertically disposed.
