摘要： A catalytic converter with excellent OSC performance and Nox purification performance. The catalytic converter includes a substrate with a cell structure and a catalyst layer formed on a cell wall surface of the substrate. The catalyst layer has a catalyst layer arranged on the upstream side and a catalyst layer arranged on the downstream side in an exhaust gas flow direction on the substrate. The catalyst layer on the upstream side includes a support containing an Al2O3—CeO2—ZrO2 ternary composite oxide (ACZ material) and an Al2O3—ZrO2 binary composite oxide (AZ material), and at least Rh that is a noble metal catalyst carried on the support, and the catalyst layer on the downstream side includes a support and Pd or Pt that is a noble metal catalyst carried on the support. In the support in the catalyst layer on the upstream side, the mass proportion of ACZ material/(ACZ material+AZ material) is in the range of 0.33 to 0.5, and greater than or equal to 75% mass Rh is carried on the Al2O3—ZrO2 binary composite oxide of the support.

摘要： An aftertreatment component for use in an exhaust aftertreatment system. The aftertreatment component comprises an aftertreatment substrate and a compressible material. The compressible material may be formed from a plastic thermoset, a rubberized material, or a metal foil which permits for the selective expansion of the substrate within the compressible material, while also reducing cost and manufacturing complexity. In various embodiments, the aftertreatment substrate and the compressible materials may be formed separately and coupled to each other, or they may be formed concurrently via coextrusion.

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