The effects of gasoline fuel HC components on individual exhaust HC emissions have been investigated. It is found that aromatics are easily emitted into exhaust gases. Consequently total HC emissions increase as aromatic components increase. Particularly, heavy aromatics (i.e. C8 ∼) are highly emitted into exhaust gases. It seems that heavy aromatics tend to be absorbed into the oil films on the...
A new concept 3-way catalyst with NOx storage-reduction capability which has sufficiently high conversion efficiency in practical range of temperature and space velocity was developed for lean burn engine. Investigations into the NOx storage mechanism showed that NOx is stored on the storage components after being oxidized by precious metals under lean conditions. Under rich conditions, the stored...
