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.

摘要： Modified calibration strategies for controlling an internal combustion engine and monitoring catalyst performance are disclosed. The modified calibration strategies are implemented using an engine (502) and test cell/catalyst chamber (510) setup wherein the engine is a Euro V 1.2 L turbo gasoline direct injection engine and test cells/ catalyst chamber are implemented as substantially free of platinum group metals (PGM) catalysts, herein referred as ZPGM catalysts, and synergized PGM (SPGM) catalysts including a stoichiometric spinel structure within the catalyst configuration. The utilization of an open ECU enables the modified calibration of the engine out targeted AFR. The conventional ECU AFR control strategies are not modified to have the ECU AFR control strategies to continue running normally and only the final engine out targeted AFR values are modified by applying offset AFR values. The modified calibration strategies improve engine operation and catalyst conversion efficiency.

摘要： Hybrid PGM-ZPGM exhaust treatment systems are disclosed. The systems include a PGM close-couple catalytic converter followed by an underfloor ZPGM catalytic converter. The disclosed hybrid systems, including PGM based catalysts and zero-PGM based catalysts may replace pure PGM based exhaust treatment systems. The ZPGM catalyst compositions used may include copper and cerium as active ZPGM catalysts. The disclosed ZPGM underfloor converters may be designed to convert leaks from close-couple converters.
