A valve operator position is determined for an exhaust gas recirculation valve (117) for an internal combustion engine (101). The valve position may be adjusted (313) for transient engine speed conditions and/or adjusted (309) for transient engine load conditions. During high transient states, the EGR valve is closed more, to allow more air to reach the cylinders of the engine, thereby improving engine performance.

La position du mécanisme de commande d'une vanne est déterminée pour une vanne de recyclage des gaz d'échappement (117) d'un moteur à combustion interne (101). La position de la vanne peut être réglée (313) pour des conditions de régime moteur transitoires et/ou réglée (309) pour des conditions de charge de moteur transitoires. Pendant des états transitoires élevés, la vanne EGR est fermée davantage pour permettre que plus d'air atteigne les cylindres du moteur, améliorant ainsi le rendement du moteur.
