(EN) FUEL INJECTION CONTROL DEVICE
(FR) DISPOSITIF DE COMMANDE D INJECTION DE CARBURANT
Abstract: front page image
(EN) A fuel injection control device that prevents a misfire is provided. The fuel injection control device comprises: target injection amount determination means 3 for determining a target injection amount of each fuel injection, so that the amount of fuel to be supplied to a cylinder in one combustion cycle is supplied in a plurality of fuel injections; and fuel injection correction amount determination means 4 for determining a fuel correction amount of one combustion cycle, wherein the fuel injection correction amount determination means 4 distributes the correction amount among each fuel injection in accordance with the ratio of a target injection amount of each fuel injection in the cylinder.
(FR) L’invention concerne un dispositif de commande d’injection de carburant capable d’empêcher tout défaut d’allumage. Le dispositif possède un moyen de détermination de quantité d’injection cible (3) afin de déterminer une quantité d’injection cible de chaque injection pour que la quantité de carburant à acheminer jusqu’à un cylindre dans un cycle de combustion soit fournie en de multiples injections, et comprend également un moyen de détermination de quantité de correction d’injection de carburant (4) afin de déterminer une quantité de correction pour un cycle de combustion. Le moyen de détermination de quantité de correction d’injection de carburant (4) répartit la quantité de correction pour chaque injection de carburant selon le rapport d’une quantité d’injection cible de chaque injection dans le cylindre.
