LABORATORY EVALUATION OF THREE-WAY CATALYSTS

A comprehensive laboratory evaluation was carried out on recent three-way catalyst formulations. The evaluation of selectivity characteristics was made in a synthetic exhaust mixture where "window" widths and positions for three-way conversion and their change after durability runs were determined. A thorough evaluation of the "oxygen- storage" capability of the catalysts was performed and the results correlated with engine dynamometer experiments. The implications of the Chanical formation of the catalysts in the overall design of the system, which includes fuel metering and feedback control along with the catalyst, are discussed. /GMRL/
