Beschreibung
Zusammenfassung:	Apparatus (A) for reducing harmful components in the exhaust gas from an engine (particularly a diesel engine), includes a nitrogen oxides (NOX) storage catalyst (12). Apparatus (A) for reducing harmful components in the exhaust gas from an engine (particularly a diesel engine), includes, in order in the direction of gas flow and in the exhaust line (4), an oxidation catalyst (9) and filter (11) for removing particles, also an exhaust gas recycle device that includes a recycle line (25) that by-passes the cylinders (2) of the engine. The new feature is that a nitrogen oxides (NOX) storage catalyst (12) is present in (4), behind (9).
