Nitrogen oxides contained in an exhaust gas emitted from a lean-burn engine-mounted internal combustion engines are eliminated with a high efficiency. In an exhaust gas purification apparatus and process for eliminating nitrogen oxides contained in a combustion exhaust gas emitted from an internal combustion engine with a reducing gas such as carbon monoxide, hydrocarbons, etc. contained in the exhaust gas in the presence of a catalyst, a catalyst comprising all of Rh, Pt and Pd, at least one member selected from alkali metals and alkaline earth metals, and Mn or its compound, supported on a porous carrier is used.

L'invention concerne la régulation effective d'oxydes d'azote contenus dans les gaz d'échappement de moteurs à combustion interne compris dans des moteurs à gaz pauvre. Un système et un procédé afférent de régulation de gaz d'échappement consistent à réguler les oxydes d'azote contenus dans les gaz d'échappement de combustion provenant de moteurs à combustion interne en présence d'un catalyseur, au moyen de gaz réducteurs tels que le monoxyde de carbone et l'hydrocarbure contenus dans les gaz d'échappement, le catalyseur utilisé comprenant un support poreux, Rh, Pt et Pd, au moins un métal alcalin ou un métal alcalino-terreux et un Mn ou son composé, tous ces éléments étant formés sur le support poreux.
