Abstract
Procedures are described for rapidly aging and for testing three-way catalysts on an engine dynamometer which are relatable to actual vehicle aging and CVS testing. The accelerated aging cycle consists of a modification of the AMA durability driving cycle; testing consists of the measurement of HC, CO and NOx conversion as a function of A/F with superimposed perturbations which simulate limit cycle variations of A/F in a closed-loop fuel control system.
