L'invention concerne un dispositif pour commander la teneur en gaz résiduel de cylindres individuels d'un moteur à combustion interne doté d'une distribution à variation mécanique intégrale et d'une commande de charge sans étranglement, et notamment d'une distribution mécaniquement rigide du côté d'échappement. Un arbre à cames côté échappement (1) présente une disposition asymétrique des cames (2); et les cames (2) de cylindres spéciaux individuels présentent sur l'arbre à cames côté échappement (1) des structures de cames différentes (3) afin d'adapter la teneur en gaz résiduel, et présentent une rotation relative de telle sorte qu'un écartement d'échappement (5) est réduit pour des cylindres ayant une teneur en gaz résiduelle excessive, ou qu'un temps d'échappement des cylindres individuels peut être adapté de telle sorte que la même quantité de gaz résiduel se règle dans tous les cylindres.
