Abstract

L'invention concerne un dispositif (10) comprenant un réducteur d'émissions et un variateur (18) de rapport. Le réducteur d'émissions comprend un piège (12) à NOx et un piège (14) à particules. Le variateur (18) de rapport est configuré pour varier le rapport entre le taux d'oxygène et le taux d'agent régénérateur d'un flux qui se déplace en direction du réducteur, de manière à régénérer partiellement le piège (12) de NOx et le piège (14) à particules en alternance au cours d'une pluralité de cycles. L'invention concerne également un procédé connexe.
