Abstract
Procédé de réduction des gaz d'échappement nocifs d'un moteur à combustion interne équipé d'un catalyseur accumulateur d'oxydes NOx, selon lequel on fournit pendant une phase de génération, un agent réducteur variable dans le temps pour évacuer l'accumulateur d'oxydes NOx. On optimise la réduction des matières polluantes dans les gaz d'échappement en tenant compte d'un fonctionnement aussi avantageux que possible du moteur à combustion interne et du système de catalyseur en fournissant en alternance dans le temps l'agent réducteur à au moins deux veines partielles distinctes.
