Abstract
A method and apparatus for aging a catalyst includes selecting an initial catalyst conditioning parameter, such as time and temperature and selecting a kinetic parameter, based on the selected time and temperature parameter, for the catalysis of CO and HC oxidation by the catalyst. A prediction of the vehicle tailpipe emission level, based on the selected kinetic parameter is made. The predicted level is then compared to a target level to determine whether the particular parameters chosen are appropriate to age the catalyst. The catalyst is then aged based on the desired selected parameters.
