摘要： An object of the present invention is to provide a heating carrier that does not heat all of exhaust gas flowing into a catalyst converter, but directly supplies, to a catalyst layer, thermal energy in the form of an instantaneous pulse to effectively activate a catalyst during a cold start-up period, and thus may reduce emission pollutants with a small amount of energy, and an exhaust gas reduction carrier having the heating carrier. In order to accomplish the object, the heating carrier of the present invention may include a main body of which the inside is formed to have a honeycomb structure, the main body being formed of a conductive ceramic material that is a nonmetallic heating element; and a catalyst layer formed by coating a first catalyst on a surface of the main body.

摘要： Active catalysts for the treatment of a low temperature exhaust gas stream are provided containing copper oxides dispersed on a spinel oxide for the direct, lean removal of nitrogen oxides from the exhaust gas stream. The low temperature, direct decomposition is accomplished without the need of a reductant molecule. In one example, CuOx may be dispersed as a monolayer on a metal oxide support, such as Co3O4 spinel oxide, synthesized using an incipient wetness impregnation technique. The CuOx/Co3O4 catalyst system converts nitric oxide to nitrogen gas with high product specificity, avoiding the production of a significant concentration of the undesirable N2O product.

摘要： Micropore zones ZMI are defined at upstream sides of partition walls 72 of a particulate filter and macropore zones ZMA are defined at downstream sides of partition walls. The pore size of the partition walls at the micropore zones is set so that the particulate matter and the ash can be trapped by the partition walls at the micropore zones, while the pore size of the partition walls at the macropore zones is set so that the ash can pass through the partition walls at the macropore zones. When a quantity of trapped particulate matter is smaller than a limit quantity, control for increasing gas which temporarily increases the flow rate of the gas which flows into the particulate filter in order to remove the ash from the particulate filter, is performed.

摘要： Synergized platinum group metals (SPGM) with ultra-low PGM loadings employed as underfloor (UF) three-way catalyst (TWC) systems with varied material compositions and configurations are disclosed. SPGM UF catalysts in which ZPGM compositions of binary and ternary spinel structures supported onto support oxides are coupled with commercialized PGM close-coupled (CC) catalysts and tested under Federal Test Procedure FTP-75 within TGDI and PI engines. The performance of the TWC systems including commercialized PGM CC and SPGM UF (with ultra-low PGM loadings) catalysts is compared to the performance of commercialized PGM CC and PGM UF catalysts. The disclosed TWC systems indicate that SPGM UF TWC catalytic performance is comparable or even exceeds high PGM-based conventional TWC catalysts, with reduced tailpipe emissions.

摘要： The exhaust gas purification device is provided with a wall flow structure substrate that has an entry-side cell, an exit-side cell and a porous partition, first catalyst parts which are formed in small pores having a relatively small pore diameter among internal pores in the partition, and second catalyst parts which are formed in large pores having a relatively large pore diameter among the internal pores in the partition. The first catalyst parts and the second catalyst parts each contain a carrier and at least one type of noble metal from among Pt, Pd and Rh supported on the carrier. The noble metal content in the first catalyst parts is smaller than the noble metal content in the second catalyst parts per 1 liter of substrate volume.

摘要： The invention relates to a particle filter (1) for an exhaust gas system (2), and to a method for producing a particle filter. The particle filter (1) comprises a plurality of flow channels (5), which extend from a first end face (6) towards a second end face (7) and which are separated from one another by porous channel walls (8). On the end faces (6, 7), the flow channels (5) each have mutual closing means (9) such that an exhaust gas (10) enters a flow channel (5) that is open on the first end face (6), flows through the channel wall (8), and escapes from the particle filter (1) by way of an adjacent flow channel (5) that is open on the second end face (7). In a direction of flow (11), the channel wall (8) has, in succession, the following layers: a particle filter layer (13); an intermediate layer (14) comprising a first SCR coating (15) having a first catalytic activity (16); a second SCR coating (18) having a second catalytic activity (19), wherein the second catalytic activity (19) is different from the first catalytic activity (16).
