Title (EN) CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE AND CONTROL METHOD FOR INTERNAL COMBUSTION ENGINE
(FR) DISPOSITIF ET PROCÉDÉ DE COMMANDE POUR MOTEUR À COMBUSTION INTERNE
(JA) 内燃機関の制御装置および内燃機関の制御方法
Abstract:
(EN) When an ECU (100) has received an engine stop command as a result of an engine stop switch (120) being turned ON, fuel supply to a fuel reforming chamber from an injector (25) is stopped while fuel supply to a combustion chamber from an injector (35) continues, and, in this state, the residual amount of reformed fuel inside passages (51, 43) is estimated. Then fuel supply to the combustion chamber (33) from the injector (35) is stopped and the internal combustion engine (1) is stopped, at a point at which this estimated amount has reached a prescribed amount or has reached zero.
(FR) Lorsqu'une unité de commande électronique (ECU) (100) a reçu une commande d'arrêt de moteur en conséquence de l'activation d'un commutateur d'arrêt (120) de moteur, l'alimentation en carburant vers une chambre de reformage de carburant à partir d'un injecteur (25) est arrêtée tandis que l'alimentation en carburant vers une chambre de combustion à partir d'un injecteur (35) continue, et, dans cet état, la quantité résiduelle de reformat à l'intérieur des passages (51, 43) est estimée. Ensuite, l'alimentation en carburant vers la chambre (33) de combustion à partir de l'injecteur (35) est arrêtée et le moteur (1) à combustion interne est arrêté, à un point tel que cette quantité estimée a atteint une quantité prescrite ou a atteint zéro.
(JA) エンジン停止スイッチ(120)のON操作によってECU(100)が機関停止指令を受けた際、インジェクタ(25)から燃料改質室への燃料供給を停止する一方、インジェクタ(35)から燃焼室への燃料供給を継続し、この状態で、通路(51,43)内の改質燃料の残量を推定する。そして、この推定量が所定量に達した時点、または、零になった時点で、インジェクタ(35)から燃焼室(33)への燃料供給を停止して内燃機関(1)を停止させる。
