Abstract

Procédé, pour un moteur à injection directe, de découpage d’une injection de carburant correspondant à un cycle moteur en sous-injections minimales, comprenant les étapes suivantes :- détermination d’un nombre maximal souhaité (N) de sous-injections en divisant une masse (M) de carburant à injecter au cours du cycle moteur par une masse minimale (Mmin) injectable et en arrondissant à l’entier inférieur,- bornage inférieure dudit nombre maximal souhaité (N) par un nombre maximal autorisé (Nmax) de sous-injections,- vérification qu’une durée d’injection (D), pour un tel nombre maximal souhaité (N) de sous-injections, est inférieure à une durée (Dmax) d’une fenêtre d’injection possible et décrémentation du nombre maximal souhaité (N) sinon, itération jusqu’à une vérification positive.
