Title (EN) FUEL INJECTION CONTROL DEVICE
(FR) DISPOSITIF DE COMMANDE D’INJECTION DE CARBURANT
(JA) 燃料噴射制御装置
Abstract:
(EN) A fuel injection control device capable of preventing a misfire. The device has a target injection amount determination means (3) for determining a target injection amount of each injection so that the amount of fuel to be supplied to a cylinder in one combustion cycle is supplied in multiple injections, and also has a fuel injection correction-amount determination means (4) for determining a correction amount for one combustion cycle. The fuel injection correction-amount determination means (4) distributes the correction amount to each fuel injection according to the ratio of a target injection amount of each 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.
(JA) 失火を防止する燃料噴射制御装置を提供する。1燃焼サイクル中に当該気筒に供給するべき量の燃料を複数回の燃料噴射で供給するように各回の目標噴射量を決定する目標噴射量決定手段3と、1燃焼サイクルの補正量を決定する燃料噴射補正量決定手段4とを備えた燃料噴射制御装置において、前記燃料噴射補正量決定手段4は、当該気筒における各回の目標噴射量の比率に応じて上記補正量を各回の燃料噴射に分配する。
