Dynamic-OSC

Dynamic OSC measured over Ce02 and NM/CeOz systems (Yao and Yu Yao 1984)... 

As discussed in sect. 1.3, under real exhaust conditions, the feed-stream quickly oscillates around the stoichiometric point. Accordingly, the OSC measured under dynamic conditions should be more relevant to actual TWC performance. Unfortunately, as already discussed in relation to table 3, the dynamic OSC of Ce02 systems has been analysed by a minority of authors. Some of the literature data are brought together in table 5.

Nevertheless, as will be shown in subsequent sections, there is a clear evidence for a strong relationship between the total/dynamic-OSC and the catalyst efficiency of the TWCs. 

Dynamic OSC was measured over all the synthesised samples using CO as reducing ent. For sake of consistency, all the measured values are reported mol (O2) niol (Ce02). As...
