Beschreibung
Zusammenfassung:	The present invention relates to an exhaust gas purification system comprising two catalytic sub-systems, wherein the first catalytic sub-system is for conversion of NOx, HC, CO and optionally particulate matter, and the second sub-system is for conversion of CO. The second sub-system locates at the downstream of the first catalytic sub-system. An air injection is positioned between the first catalytic sub-system and second catalytic sub-system.
