The introduction of gasoline direct injection technology into the European market will
depend mainly on the availability of an effective and durable aftertreatment system, in order …

A commercial NOx-storage catalyst for gasoline applications containing Ba/CeO₂/Al₂O₃,
platinum, palladium and rhodium has been sulfated on the engine bench at 390 and 510° C …

Influence of sulfur poisoning on NOx storage-reduction catalysts (NSR catalysts) was
examined using both model gas and an actual vehicle. Deterioration of NSR catalysts is …

A commercial NOx-storage catalyst for gasoline applications containing platinum, palladium
and rhodium together with Ba/CeO2/Al2O3 has been sulfated on the engine bench at 390 …

A commercial NOx-storage catalyst (NSC) has been subjected to different aging procedures
on the engine bench simulating 100,000 km mileage. The aging consisted of cyclical sulfur …

Engine and laboratory tests were carried out to examine the performance of NOx adsorption
catalysts for gasoline lean burn engines in fresh and aged condition. The results show that …

One possibility to improve the fuel economy of Sl-engines is to run the engine with a lean air-
fuel-ratio (AFR). Hydrocarbon and carbon monoxide after-treatment has been proven under …

NOx storage-reduction catalysts (NSR catalysts) have developed for lean-burn and gasoline
direct injection engines. One of the main causes of deterioration of NSR catalysts is sulfur …

Even though substantial improvements have been made for the lean NOx trap (LNT) catalyst
in recent years, the durability still remains problematic because of the sulfur poisoning and …

A detailed study of the sulfation and desulfation phenomena of a NOx storage reduction
catalyst using synthetic gas bench is presented. The experimental observations and results …
