摘要： Methods for monitoring thermal characteristics of oxidation catalyst (OC) catalytic composition(s) (CC) are provided, and comprise communicating exhaust gas to the OC, and determining a temperature change of the CC for the time frame based on a plurality of heat sources including heat imparted to the CC from exhaust gas enthalpy, heat imparted to the CC via oxidation of HC and/or CO in exhaust gas, heat imparted to the CC via water present in the exhaust gas condensing on the CC or heat removed from the CC via water evaporating from the CC, and optionally heat exchanged between the CC and the ambient environment. Heat imparted to the CC via water condensing on the CC can be determined using an increasing relative humidity proximate the CC, and heat removed from the CC via water evaporating from the CC can be determined using a decreasing relative humidity proximate the CC.

摘要： Described are exhaust gas treatment systems for treatment of a gasoline engine exhaust gas stream. The exhaust gas treatment systems comprise an ammonia generating and hydrocarbon oxidation catalyst, a TWC catalyst, and an ammonia selective catalytic reduction (SCR) catalyst downstream of the TWC catalyst. The ammonia generating and hydrocarbon oxidation catalyst comprises a refractory metal oxide support, a platinum component, and a palladium component. The ammonia generating and hydrocarbon oxidation catalyst is substantially free of ceria and substantially free of NOx storage components. The platinum and palladium components are present in a platinum to palladium ratio of greater than about 1 to 1.
