Abstract: A catalytic converter (9) is interposed in an exhaust passage (3) of an internal combustion engine (1). In the converter (9), a plurality of carriers (21A-21D) are disposed in series with gaps (G1-G3). Each carrier (21A-21D) comprises a hydrocarbon trapping layer (25), a three-way catalyst layer (26) and a number of passages (24) facing the three-way catalyst layer (26). The gaps (G1-G3) interrupts heat transfer between the carriers in order to retard temperature increase in the hydrocarbon trapping layer (25) and promotes a turbulence in exhaust gas flow in the converter (9) in order to homogenize the exhaust gas dispersion in a radial direction, thereby enhancing the hydrocarbon purification performance of the converter (9).

Abstract: A hydrocarbon trapping layer (25) is formed by coating a hydrocarbon trapping material onto a carrier (21A). A number of exhaust gas passages (34) are formed in the carrier (21A) and a plurality of slits (22) are formed on the carrier (21A) to cross the passages (24) in a transverse orientation. The slits (22) delay temperature increases in the downstream hydrocarbon trapping layer (25) and delay the release of trapped hydrocarbons therefrom. This is due to blocking the transmission of heat to the downstream hydrocarbon trapping layer (25) from the upstream hydrocarbon trapping layer (25). The slits (22) further produce a turbulent flow in the flow of exhaust gas and promote diffusion of exhaust gas over the entire surface of the carrier (21A).

Abstract: A rolling regeneration diesel particulate filter and filtering process that utilizes NO produced in the process to generate additional amounts of NO2 than the NO2 produced by the diesel engine. The process includes the step of flowing diesel engine combustion exhaust through a filter system including a first section and a second section. The first section is positioned upstream of the second section with respect to the direction of the flow of the diesel engine exhaust through the filter. The first section includes a foam constructed and arranged to trap carbon-based particulates in the exhaust. A first catalyst is carried by the foam to promote the conversion of NO in the exhaust from the diesel engine to NO2. The first catalyst also promotes the reaction of NO2 with at least a portion of the carbon-based particulates trapped by the foam to form CO and NO. The first catalyst carried by the foam also promotes the oxidation of CO to CO2, and the oxidation of NO, generated by the reaction of NO2 with carbon, to generate additional amounts of NO2. The additional amounts of NO2 are also utilized to oxidize the carbon-based particulates. The second section of the filter system includes a wall flow monolith having a plurality of through hole cells formed therein running the longitudinal length of the monolith. The monolith is constructed and arranged to trap particulates in the exhaust and to promote the reaction of NO2 and carbon to produce NO and CO. The ceramic foam may also be received in and surrounded by the wall flow filter.

Abstract: A cell structure mounting container comprises a cell structure stored within a metal container. The cell structure is held within the metal container by providing a compressed resilience material having cushioning characteristics between the cell structure and the metal container in a compressed state. The compressed resilience material is a heat-resistant and low-expansion material containing ceramic fibers or ceramic fibers and heat-resistant metal fibers. Accordingly, compression characteristics which do not greatly fluctuate within the usage temperature range are obtained, the compression force acting on the periphery portion of the cell structure does not change greatly, and further, the compression force acts essentially uniformly on the periphery portion of the cell structure. Thus, a cell structure mounting container and an assembly thereof can be provided wherein there is little change in compressive pressure on the cell structure within the metal container within the usage temperature range of the catalytic converter or the like, and the compressive pressure distribution is uniform, thereby preventing damage to the cell structure.
