Abstract

L'invention concerne un procédé de contrôle pour un moteur à combustion interne (1) comprenant un circuit d'admission (2) comprenant un conduit d'admission principal (5) et un conduit d'admission secondaire (5a) et un circuit d'échappement (3) qui comprend un système de post-traitement des gaz d'échappement (19), le moteur pouvant fonctionner dans une phase de régénération pour régénérer le système de post-traitement (19) au cours de laquelle le circuit d'admission est vanné par un volet d'admission (14) et une phase normale sans vannage par ce volet (14) caractérisé en ce que l'on adapte la section de passage de l'air dans le conduit d'admission secondaire (5a) par un moyen d'obturation (20) pour diminuer le contraste de bruit d'admission d'air entre les phases de régénération et les phases normales.
