Wirtschaftswissenschaft und Ethik,d in fewer days (by running 24 h days) than for vehicle aging. Dynamometer-controlled engine facilities are used for accelerated aging in which the catalysts are exposed to poisons and high temperatures as well as for short emissions tests. A short description of catalyst screening tests as described in published reports follows.
