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 emission control catalyst structure for promoting the contact between a gas to be treated and a catalyst by disturbing an exhaust gas flow inside a gas flow passage, and being suitable for obtaining a high-efficient and compact exhaust gas treating apparatus, comprising a plurality of catalyst elements supporting catalyst components on the surface thereof, formed by alternately forming flat sheet portions and step portions so that a flat sheet portion and a step portion form an angle falling within a specific range, and laminated with one another in a frame body. The catalyst element is formed by laminating a large number of metal, ceramics or glass net-like members having a large number of through-holes penetrating through both surfaces. The exhaust emission control catalyst structure is such that dust is hardly deposited between the catalyst elements and sufficient strength can be obtained even when the thickness of the catalyst element is reduced. This catalyst structure is used as an exhaust gas treating apparatus when disposed inside an exhaust gas flue. When this exhaust gas treating apparatus is employed, the pressure loss can be limited without damaging the catalyst element, and exhaust gas treating can be effected efficiently.

摘要： According to the present invention, a metal carrier consists of an end wall member formed at least one axial end portion of a honeycomb body and an outer cylinder reinforcing layer formed by bonding at an axially intermediate portion up to 1/4 of a total number of windings starting at the outermost periphery, whereby the honeycomb body is furnished with suitable expansibility and contractibility. Since the combining of the honeycomb body with an outer cylinder is done mainly at the outermost periphery of the outer cylinder reinforcing layer of the honeycomb body, the thermal stress occurring between the honeycomb body and outer cylinder can be minimized with the strength at a high temperature of the metal carrier maintained at a predetermined level. This prevents the metal carrier from being broken.

摘要： A catalyzer, in particular for internal combustion engines, has a diffusor 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 located 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 of 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 alpha 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.
