Abstract

A system (80) for controlled regeneration of a lean NOx trap for an internal combustion engine. The system may include regenerating one trap (82, 83) or a portion of a lean NOx trap while using another trap or portion of the lean NOx trap for an exhaust, and then interchanging operations. The portions may be individual structures or of one structure. The trap may be a rotating element that is regenerated in part at a time. There may be valves (91, 93, 94) that direct the exhaust gas through one trap and regeneration gas through another trap and vice versa. Also, an exhaust gas system with regeneration may include temperature, pressure, NOx and differential pressure sensors. A processor may be connected to the sensors. There may be emission sampling lines connected to different parts of the system and to a collector to take, store, detect and analysed samples. A processor may be connected to the collector.
