The Importance of Reversible Deactivation Dynamics for On-Board Catalyst Control and Obd Systems

Transient measurements of pre- and post-catalyst exhaust gas components and AFR are used to investigate the relationship between post-catalyst AFR and tailpipe emissions. This relationship is critical to the ability of on-board oxygen storage dominated models to predict emissions levels. The results...
