Nevertheless, the required tight stoichiometry constraints in a randomly oscillating dynamic combustion were not easily attainable. There was a need for a composition smoothing device/material akin to a surge tank in a hydraulic system or [Pg.344]

The TWC has undergone significant advances during the past 20 years or so, a number of which have involved major changes in the way ceria is deployed. In the early years (roughly 1981-1985), the TWC formulation was relatively simple and consisted of noble metals co-impregnated with ceria onto alumina. Even this [Pg.346]
