(EN) FUEL INJECTION SYSTEM
(FR) SYSTÈME D'INJECTION DE CARBURANT
(JA) 燃料噴射システム
要約
(EN)
A fuel injection system comprising a first control device for outputting a first pulse signal stipulating the charging time of a liquid fuel injection valve, and a second control device for generating a second pulse signal stipulating the charging time of a gas fuel injection valve on the basis of the first pulse signal during gas fuel injection and outputting the second pulse signal to the gas fuel injection valve. When the occurrence of a fuel cut is detected during the gas fuel injection, the second control device implements a cleaning mode for outputting the first pulse signal inputted from the first control device to the liquid fuel injection valve after the fuel cut has ended.
(FR)
Système d'injection de carburant comprenant un premier dispositif de commande destiné à sortir un premier signal d'impulsion stipulant le temps de charge d'une soupape d'injection de carburant liquide, et un second dispositif de commande destiné à générer un second signal d'impulsion stipulant le temps de charge d'une soupape d'injection de carburant gazeux sur la base du premier signal d'impulsion pendant l'injection de carburant gazeux et à sortir le second signal d'impulsion sur la soupape d'injection de carburant gazeux. Lorsque l'apparition d'une interruption de carburant est détectée pendant l'injection de carburant gazeux, le second dispositif de commande exécute un mode nettoyage pour sortir le premier signal d'impulsion entré depuis le premier dispositif de commande sur la soupape d'injection de carburant liquide à la fin de l'interruption de carburant.
(JA)
 燃料噴射システムは、液体燃料噴射弁の通電時間を規定する第1パルス信号を出力する第1制御装置と、気体燃料噴射時には前記第1パルス信号を基に気体燃料噴射弁の通電時間を規定する第2パルス信号を生成して前記気体燃料噴射弁に出力する第2制御装置と、を備え、前記第2制御装置は、前記気体燃料噴射時に燃料カットの発生を検知した場合、前記燃料カットの終了後に前記第1制御装置から入力される前記第1パルス信号を前記液体燃料噴射弁に出力するクリーニングモードを実施する。
