摘要： Close-coupled catalysts (CCC) for TWC applications are disclosed. The novel CCCs are implemented using light-weighted ceramic substrates in which a thin coating employing a low loading of Iron (Fe)-activated Rhodium (Rh) material composition, with Iron loadings and an OSM of Ceria-Zirconia, are deposited onto the substrates. Different CCC samples are produced to determine and/or verify improved light-off (LO) and NOX conversion of the CCCs. Other CCC samples produced are a CCC including a standard (non-activated) Rh thin coating and a heavily loaded CCC with a single coating of Pd/Rh material composition. The CCC samples are aged under dyno-aging using the multi-mode aging cycle and their performance tested using a car engine with ports on the exhaust to measure the emissions, according to the testing protocol in the Environmental Protection Agency Federal Test Procedure 75. During testing, the thin coatings of Fe-activated Rh exhibit improved light-off and NOx conversion efficiency.

摘要： A vehicle exhaust system is provided and comprises a catalyst positioned in an exhaust passage of a vehicle. The catalyst is in the form of a washcoat supported on a substrate. The system includes a phase change material located adjacent to the catalyst to maintain the temperature of the catalyst between engine shut-down and subsequent start-up as well as to regulate the temperature during engine operation. In some embodiments, the phase change material comprises particles of a metal or metal alloy encapsulated in a ceramic material. The metal or metal alloy is adapted to have a phase change that occurs within a temperature range wherein the catalyst is active.
