Abstract

Procédé de régulation d'injection d'essence et d'alcool d'un moteur à combustion interne (M), caractérisé en ce qu'une injection directe de carburant unique alimente le moteur, le carburant étant soit de l'alcool au-dessus d'un seuil de charge critique (S ) soit de l'essence au-deçà de cette valeur de seuil, et en ce que le moteur (M) est alimenté en carburant parmi l'une de deux voies d'injection directe (T1, T2) en alcool et en essence, cette alimentation du moteur (M) basculant directement d'un carburant à l'autre du fait que l'ouverture d'une voie d'injection (T1, T2) actionne (22) la fermeture simultanée ou quasi-simultanée de l'autre voie d'injection (T2, T1).A method of regulating the injection of gasoline and alcohol of an internal combustion engine (M), characterized in that a single direct fuel injection is supplied to the engine, the fuel being either alcohol above a critical load threshold (S) is gasoline below this threshold value, and in that the engine (M) is supplied with fuel from one of two direct injection channels (T1 , T2) in alcohol and in gasoline, this supply of the engine (M) switching directly from one fuel to the other because the opening of an injection channel (T1, T2) actuates (22) the closing simultaneous or near-simultaneous with the other injection route (T2, T1).
